You Asked

Hello Sir,
My problem is thru stored procedure or pl/sql annonyms block how to write the records into Excell sheet in Oracle 8i.My collique is doing thru vb.But We want to achieve thru oracle pl/sql.For ex,I am getting all employee records from employee table and instead of spooling into a text file I want to write into excell sheet.
You were asked the working environment
Windows NT Workstation
Oracle 8i
Server Located in same workstation
There have no cartridges and app server or web server even not from forms.

Our Achievement has to be done thru pl/sql procedure.
For extreem case if not possible only in database server...please explain how to do in Oracle Web server 3.

Thank You


and we said...

We can do this with a straight plsql procedure. There are more then one format we can use to write an excel file -- from CSV to SYLK. I will demonstrate the SYLK format as I already have the code and it offers the ability to do much fancier stuff like fonts, headings, formulas and such.

We will use UTL_FILE (see the supplied packages guide for setup info on that package. You need an init.ora parameter set for this to work correctly). UTL_FILE allows us to write a file on the server and since your workstation = server, this should work nicely for you.

Here is the code with an example. It should get you going:

Rem NAME
Rem owasylk.sql - Dump to Spreadsheet with formatting
Rem DESCRIPTION
Rem This package provides an API to generate a file in the
Rem SYLK file format. This allow for formatting in a
Rem spreadsheet with only a ascii text file. This version
Rem of owa_sylk is specific to Oracle8.
Rem NOTES

/*
This package allows you to send the results of any query to
a spreadsheet using UTL_FILE

parameters:
p_query - a text string of the query. The query
can be parameterized
using the :VARAIBLE syntax. See example
below.

p_parm_names - an owaSylkArray of the paramter names
used as bind variables in p_query

p_parm_values - an owaSylkArray of the values of the
bind variable names. The values
muse reside in the same index as the
name it corresponds to.

p_cursor - an open cursor that has had the query
parsed already.

p_sum_column - a owaSylkArray of 'Y's and 'N's
corresponding to the location
of the columns selected in p_query.
A value of NYNYY will result
in the 2nd, 4th and 5th columns being
summed in the resulting
spreadsheet.

p_max_rows - the maxium number of row to return.

p_show_null_as - how to display nulls in the spreadsheet

p_show_grid - show/hide the grid in the spreadsheet.

p_show_col_headers - show/hide the row/column headers
in the spreadsheet.

p_font_name - the name of the font

p_widths - a owaSylkArray of column widths. This
will override the default column widths.

p_headings - a owaSylkArray of column titles.
This will override the default column
titles.

p_strip_html - this will remove the HTML tags from the
results before
displaying them in the spreadsheet cells.
Useful when the
query selects an anchor tag. Only the
text between <a href>
and </a> tags will be sent to the
spreadsheet.

examples:

This example will create a spreadsheet of all the MANAGERS
in the scott.emp table and will sum up the salaries
and commissions for them. No grid will be in the
spreadsheet.



declare
output utl_file.file_type;
begin
output := utl_file.fopen( 'c:\temp\', 'emp1.slk', 'w',32000 );

owa_sylk.show(
p_file => output,
p_query => 'select empno id, ename employee,
sal Salary, comm commission ' ||
'from scott.emp ' ||
'where job = :JOB ' ||
'and sal > :SAL',
p_parm_names =>
owa_sylk.owaSylkArray( 'JOB', 'SAL'),
p_parm_values =>
owa_sylk.owaSylkArray( 'MANAGER', '2000' ),
p_sum_column =>
owa_sylk.owaSylkArray( 'N', 'N', 'Y', 'Y'),
p_show_grid => 'NO' );

utl_file.fclose( output );
end;



This example will create the same spreadsheet but will
send in a pre-parsed cursor instead

declare
l_cursor number := dbms_sql.open_cursor;
output utl_file.file_type;
begin
output := utl_file.fopen( 'c:\temp\', 'emp2.slk', 'w',32000 );

dbms_sql.parse( l_cursor,
'select empno id, ename employee,
sal Salary, comm commission ' ||
'from scott.emp ' ||
'where job = ''MANAGER'' ' ||
'and sal > 2000',
dbms_sql.native );

owa_sylk.show(
p_file => output ,
p_cursor => l_cursor,
p_sum_column =>
owa_sylk.owaSylkArray( 'N', 'N', 'Y', 'Y' ),
p_show_grid => 'NO' );
dbms_sql.close_cursor( l_cursor );
utl_file.fclose( output );
end;

Please bear with me i made mistake in the question

Richard, December 12, 2001 - 6:20 am UTC

My question is that I have 3 tables, 2 of which contain many records. I have
to write a code(plsql) that will select all matching records and insert them
into the 3rd table(C) .The real problem is that table A(not table C) must contain records in
either Excel or Access file format which is saved on a diskette. Thus apart
from selecting records from table B to be inserted into table C, I should also
find a way of reading or selecting matching records(in table A ) saved on the floppy
diskette.
Can this be achievable in oracle7.3.2? Can you give me a simple code to do that?
NB. Table A(studnumber,subject,level)
Table B(studnumber,dept,year)
Table C(studnumber,subject,level,dept,year).
Thanks a lot.
Please bear with me.

not understanding the difference here.

I showed you how to populate table C with an insert into select.

I showed you how to dump any query to a file using UTL_FILE, be it against table A, table C, table foobar.

A reader, January 23, 2002 - 3:18 pm UTC

hi Tom.

I want to give heading to excel report inside spreadsheet?

e.g

REPORT FOR SALES DEPT.

then ...........all data


Can you help me?

Tom Kyte
January 23, 2002 - 6:22 pm UTC

the SYLK file format is an open, documented standard. You can search www.google.com for references to it, they can show you how to format a sylk file in that fashion. then you just have to modify the code....

Exporting in Lotus 1-2-3

Arvind, January 24, 2002 - 12:47 am UTC

This is very useful for use

Is this method is also applicable for Lotus 1-2-3 spreadsheets. Secondly can we import data from Lotus 1-2-3 sheets into oracle

Tom Kyte
January 25, 2002 - 6:55 am UTC

if lotus can read sylk files, sure (i think it can, at least the last time I saw it about 8 years ago it could, didn't even know it was still around).

You would EXPORT the data from lotus into a delimited file and use sqlldr to load it.

A reader, January 24, 2002 - 9:12 am UTC

Tom

i search www.googli.com web site for SYLK utility.
and i found sylk FILE FORMAT. I change you program for report heading.

ThnakS a lot

YOU ARE THE "BEST"



Good One But

Parag, January 24, 2002 - 10:04 am UTC

Hi :

I am using Oralce 8.1.7 on SUN. I have Fired the code give by U . After Creating Package , When i try to execute the code (where we used to call package ) it's giving me foll error.

ERROR at line 1:
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "SYS.UTL_FILE", line 101

Please help me out.

Tom Kyte
January 25, 2002 - 8:16 am UTC

you have not setup the necessary INIT.ORA parameters for utl-file. Please refer to the supplied packages guide, you need to setup the utl_file_dir init.ora parameter.

Why you get ORA-06510: PL/SQL: unhandled user-defined exception ...

Ravi, January 24, 2002 - 11:31 am UTC

You get this error if:
1 You have not specified utl_file_dir init parameter (as Tom warned)
2 You have specified it, but as a specific directory c:\temp

Solution to 2 is :
- Specify it as utl_file_dir = *
- Or change the directory to 'c:\temp' from 'c:\temp\' in Tom's code

I tested on Windows.

see the Oracle server reference manual and read about the utl_file_dir init.ora parameter which you NEED to set up

need suggestion

Mohd Ahmed, January 27, 2002 - 6:08 am UTC

What are your suggestions in order to have this working on 7.3.4.4 instead of 8i?


Tom Kyte
January 27, 2002 - 10:44 am UTC

You'll have to recode it to not use the new collection type syntax available with 8.0 and up -- use plsql index by table types instead. So, thats really the only changes you'll have to make. It's not as easy to initialize plsql index by tables as it is collection types -- so, instead of the caller coding:


declare
output utl_file.file_type;
begin
output := utl_file.fopen( 'c:\temp\', 'emp1.slk', 'w',32000 );

owa_sylk.show(
...
p_parm_names => owa_sylk.owaSylkArray( 'JOB', 'SAL'),
...

p_show_grid => 'NO' );

utl_file.fclose( output );
end;

they'll have to code (after you rewrite the owasylk package)
declare
output utl_file.file_type;
l_parm_names owa_sylk.owaSylkArray;
begin
output := utl_file.fopen( 'c:\temp\', 'emp1.slk', 'w',32000 );

l_parm_names(1) := 'JOB';
l_parm_names(2) := 'SAL';

owa_sylk.show(
...
p_parm_names => l_parm_names,
...

p_show_grid => 'NO' );

utl_file.fclose( output );
end;



Very neat.

At present I create reports as txt files which are opened as delimited in Excel.

This is much better!
No need for formatting etc.

Thanks.





Bind variables in Owa_SYLK

Tom, August 09, 2002 - 4:14 pm UTC

Tom,

One question. I notice that Owa_sylk passes in a table of bind name and a table of bind values as varchar2 data, although the columns to be bound may be numbers / dates. Am I misunderstanding how dbms_sql.bind_value works, or will this not cause each variable to be bound as a string, thus meaning that indexes will be ignored on predicates where the datatype is not a string.


Tom Kyte
August 09, 2002 - 4:42 pm UTC

you should use to_number and to_date where appropriate, eg:


select * from emp where empno = to_number(:x)

select * from emp where hiredate = to_date( :x )

select * from emp where ename = :x


would all be appropriate for example.

for TEXT_IO how to work

A reader, September 12, 2002 - 11:31 am UTC

Hi, Tom,

I want to write the file into client machine by TEXT_IO.
You told us we can change from UTL_FILE to TEXT_IO?
And I create the package "owa_sylk" in the "program unit"
within form, and also change all the UTL_FILE to
TEXT_IO type. But when I compiled it, there is an error:
DBMS_SQL(...., native)<---- error.
How can I solve that?

Thanks


Tom Kyte
September 12, 2002 - 3:44 pm UTC

in forms, you probably want to use EXEC_SQL, you can use DBMS_SQL but you cannot in some releases of forms reference a packaged variable like that.

Just use the number 1

.....
-- CONSTANTS
--
v6 constant integer := 0;
native constant integer := 1;
v7 constant integer := 2;
--


Ignore that

A reader, September 12, 2002 - 12:12 pm UTC

Hi, Tom

I solved that "dbms_sql.native" problem on the client side.
So, please ignore that question.

Thanks and have a nice day.




"Text" cell format, how?

A reader, September 12, 2002 - 12:26 pm UTC

Hi, Tom,

Thanks for you excellent works.
My question is: we got data write into the excel file, but
this is actually in "general" cell format. What i want to do is generate the data in "TEXT" format. In you "print_row" codes, can we implement that? Could you shed
a light on this lease?

Thanks,


Tom Kyte
September 12, 2002 - 4:11 pm UTC

You'll have to dig up the SYLK file format on the web -- google it, it is a documented standard.

Dynamic Data type

A reader, September 15, 2002 - 11:43 pm UTC

Hi, Tom,

Appreciate for the solution.
There are basically 3 types of data in the database:
VARCHAR2, NUMBER and Date. I want to dynamically write them
into excel datasheet. So I have to dynamically get the data type of each column and then wirte them into the column(row) based on the derived data type. Could you shed some light on this topic please? Also for the Number, how do I know it is just NUMBER or NUMBER(6,2)? Are there any difference to process that?
At last, we want to use JAVA implement the same function(
write data into excel), for example, SQLJ or JDBC. Could you compare your solution and JAVA solution in the
aspect of performance and easy of use as well as security
please?

Thanks a million

Tom Kyte
September 16, 2002 - 7:17 am UTC

No you don't.

A number can be fetched into a varchar2.
A date can be fetched into a varchar2.

When you print -- they will all be converted into varchar2 regardless.

Hence, I just fetch them into varchar2. This utility handles dates/numbers "as is".

A comparision of this to java

o this is written, the java one is not
o this is easy to code, performant, and will never throw a Null pointer exception
o you need to setup utl_file_dir to make this plsql version work (in releases before 9iR2, in 9iR2 you can use a directory object instead). You have to use dbms_java.grant_permission to make this work in java -- more or less the same.

Java will not make this any "better", trust me on that one. Why do you care what language something is written in.

Bear with me

A reader, September 16, 2002 - 10:57 am UTC

Hi, Tom,

Please bear with me, I'm kinda insist my opinion.
Because what I want to do is "pre-format" each column when
write them to the excelsheet. The person who receives
the excelsheet probably doesn't know the datatype for
each column(beacuse it is always "GENERAL" format when he/she opens the column(cell) format property). So by this "pre-format", each column will be in the right format when the guy open the column(cell) format and know what the "original" format of the data. That means we are not only write data into excel but also prepare the file(format column) for the person with no/little DB knowledge.
We are aware of we can do this by using PRO/C* or JAVA because we can write them into excel by correct format---
"%s, %i, %d" and it is in the right format and ready to
be checked by opening the format property in the excelsheet.
I remember there are some lines of codes which handle
finding datatypes of the outcome from a query dynamically,
but I can not find it, would you give me that pointer please?

Thanks a million


Tom Kyte
September 16, 2002 - 7:33 pm UTC

you can modify the code, which uses dbms_sql, to call the describe routine in dbms_sql to discover the datatype, scale and precision and do whatever formatting output you like.



Date format

A reader, September 17, 2002 - 5:04 pm UTC

Hi, Tom,

I already solved the problem(datatype) by myself.
One more problem;
How can I find the DATE value including time?
I try to extract the date value(including time) and
manipulate it with the other times and write the result
to excel.
I can not use "gcvalue" because it don't allow me to
for example:
SELECT to_date(gcvalue, 'DD-MON-YYYY HH24:MI:SS')
- to_date(other_date, 'DD-MON-YYYY HH24:MI:SS')
FROM DUAL;
It can only do this(with YY), but it doesn't give time portion:
SELECT to_date(gcvalue, 'DD-MOC-YY HH24:MI:SS')
- to_date(other_date, 'DD-MON-YY
HH24:MI:SS')
I tried to define another variable(for date):
g_dvalue DATE and use:
dbms_sql.column_value( c, i, g_dvalue ) if it is
a date type, but it gives me error(not match col type).
Again, I tried to do:
dbms_sql.define_column( p_cursor, i, g_dvalue, 32765)
brfore getting date value but it give me another error.
So, I'm running out gas, and could you let me know how
can I get exectly date value(including time) and write
them into excel by correct format(I can do this part)?

Thanks a million



Tom Kyte

looks like you are trying to get the difference between two dates right? if so, see:
</code> http://asktom.oracle.com/Misc/DateDiff.html <code>


Time portion

A reader, September 17, 2002 - 11:41 pm UTC

Nop, SIr,

The problem is that I can not get the time portion out of the variable "g_cvalue"(only date portion with two digits
of year show up no matter what format I specify, e.g even
I use 'DD-MON-YYYY HH24:MI:SS' to explicitly covert it and
display to the output).
I can handle the diff between two dates.
Is VARCHAR2 variable such as "g_cvalue" capable of getting
the value from binded column even the type is date?

Thanks,


Tom Kyte
September 18, 2002 - 7:22 am UTC

if you select

to_char( g_cvalue, 'dd-mon-yyyy hh24:mi:ss' )

you will most certainly get that string with TIME in it.. You would really really need to provide a complete YET very concise example of your issue in order for me to comment, because I just don't understand what your problem could be. CONCISE being an important word in that sentence.

Explain

A reader, September 18, 2002 - 9:44 am UTC

Hi, TOm,

Thanks for your time.
Ok, here is the problem:
if I call the package by passing a query which includes a column having a date type, then the time portion is not show up and only comes with two digits year format even I specified explicitly the date format that i want.
For example:
dbms_sql.parse( l_cursor, 'select * from emp', DBMS_SQL.NATIVE);
owa_sylk.show(p_file => output , p_cursor => l_cursor,
p_show_grid => 'YES' );
in the above format, there is a "hiredate" date type field
which can not be correctly displayed in excel after generating the file. But if I do:
dbms_sql.parse( l_cursor, 'select empno, ename, mgr...
to_char(credate, 'DD-MM-YYYY HH24:MI:SS') hd from emp', DBMS_SQL.NATIVE);
it can displayed the date correctly in excel but it is in the format of "TEXT" because it belongs to VARCHAR2.
So, my problem is: I still can not extract the time portion for a date type column, could you test the code by just passing query "select * from emp", write hiredate as a time format(col_type=12), and finally you will find the hiredate column is not correctly displayed if you open the excel sheet.
Can the variable g_cvalue be used to get the value of date format(i mean including TIME portion and be any format if i specified the date format explicitly) if we know the type of the column is 12(col_type=12)?

Thanks


Tom Kyte
September 18, 2002 - 3:03 pm UTC

pass it a query that formats the date as you like (eg: don't use *, use empno, ename, to_char(hiredate, 'dd-mon-yyyy hh24:mi:ss' ), .....

OR issue:

execute immediate 'alter session set nls_date_format = ''dd-mon-yyyy hh24:mi:ss'' ';

before calling owa_sylk to change the default date format.



If you want to do this in owa_sylk you will have to

a) check for the datatype are you are
b) make sure you bind a date datatype -- not a character string
c) format it however you like after getting it


I'll not be of any more use on this one cause

a) you get the time component (you said so -- when (I use to_char......)
b) it is how you need to output it for excel that you need to discover
c) I don't know squat about excel ;)



Is it possible to create multiple sheets in Excel file

sylk is sylk. worksheets are MS's thing. At this point, you would have to ask MS -- what is the standard flat file format I can write that lets me use all of your features.

We can

A reader, September 18, 2002 - 1:03 pm UTC

Hi,

We can create separate worksheet by learning from sample files. All we lack is the current standard format file of
SYLK supported by MICROSOFT, the lastest one I can find is still for EXCEL 2.0 in published in 1985-1986. But as I said we CAN create separate worksheet.

Thanks


Thanks

A reader, September 18, 2002 - 3:21 pm UTC

Hi, TOm,

I solved the problem of not showing time portion by g_cvalue, because it is VARHCAR2 type(g_cvalue)--maybe
it is a bug. So I bind the date format by declare another
date variable g_dvalue in order to match them when i
get the column value.

Thanks anyway for your useful codes.

BTW, we can do most of the thing to excel format by using
this code, but you must to modify the code to your own needs.


Number of records in SYLK

A reader, September 18, 2002 - 5:05 pm UTC

Hi, Tom,

What is the largest number of records we can write into
excel by using this code?

I have tried to write about 450,000 records(from a table, pure query) into excel(SYLK) by this method, but I only got 10001 reocrds showup after I open the SYLK file under MS excel.

Please clarify.

THanks

450k -- no way, they don't do that

Speed

Parasheh, October 04, 2002 - 3:26 pm UTC

Hi, Tom,

Appreciate you code.

Ine thing I want to ask is that the speed of code execution
is very slow if the table is fairly large(both # of columns
and # of records are very large, e.g: million records and
100 columns). it will take at least 5~20 minutes to finish
the job). Would mind tell us how to increase the speed
please?

Thanks

You could recode to use array processing....

You could use a faster method such as C (search for array_flat on this site, code already exists)

dbms_sql can parse infinitely complex queries -- it is just an interface to the database.

hows about this -- you add a little debug -- or take your query and try:

declare
type rc is ref cursor;
l_cursor rc;
<other variables>
begin
open L_cursor for 'select * from ( ' || .......
using variable, variable, ....;
end;
/

just to see if you have it right. I see immediately:

'and trunc(e.createdt) = trunc(sysdate)'||
'union'||
'select c.s

for example which will result in :

'and trunc(e.createdt) = trunc(sysdate)unionselect c.s


suggestion:

don't concatenate, just let it flow:

p_query => 'select *
from ( select *
from ( select *
from dual )
)
', .....


you don't need to break it up as you have -- but if you do -- watch the whitespace!!!!

how to solve?

Thank you.

Tom Kyte
May 03, 2003 - 11:54 am UTC

1) you would need to research the SYLK file format to see if that is even possible. SYLK is open systems, portable, generic. worksheets -- are not

2) "it doesn't work" is ambigous as "my car won't start -- why". Sure it works, we can write a big5 file -- can excel read it?

Excellent.

Tamas Szecsy, June 04, 2003 - 4:27 am UTC

Just a small comment on my part: I faced the same problem and decided to the other way: while it is somewhat more difficult and less portable to other spreadsheets, I wrote a small package that writes Excel 2000 specific HTML file with xls extension. This way I can make use of the many features of Excel - SYLK is somewhat limited - and still need no OLE or Excel installed and can use utl_file to write a simple ASCII file.

Here is my easy way to pump html to excel

Tom,
I screwed I admit. The package runs but now I have a different problem. The SYLK file that it makes is invalid, it says that Excell convert some of the cells. Now after further debugging I got the root of the problem. Please refer to your print_heading procedure, there you have a line as : p('ID;ORACLE' ); which basically writes the first record as ID which according to the Standard is for identifying the file as SYLK. If I comment off that then I don't get any formats/fonts etc. But if I keep it and generate the file, although it gives me the above mentioned error , but it keeps the fonts for the report. I am at a total loss here. Could you help me in this regard.

Thanks

go back to the original code -- unedited -- as provided.

can you reproduce with that?

if not, figure out what you changed to make it so.

if yes, then give us a test case -- create table, insert into table just enough data, the call to owa_sylk. then we can look at it.

I have got the crux!!

Arindam Mukherjee, November 07, 2003 - 5:54 pm UTC

Tom,
I could figure out what was the problem. I changed the code which inserted invalid characters in the SYLK. Sorry I troubled you. I have a related question though.
In the package :
procedure show(
p_file in utl_file.file_type,
p_cursor in integer,
p_sum_column in owaSylkArray default owaSylkArray(),
p_max_rows in number default 10000,
p_show_null_as in varchar2 default null,
p_show_grid in varchar2 default 'YES',
p_show_col_headers in varchar2 default 'YES',
p_font_name in varchar2 default 'Courier New',
p_widths in owaSylkArray default owaSylkArray(),
p_titles in owaSylkArray default owaSylkArray(),
p_strip_html in varchar2 default 'YES',
p_report_name in varchar2,
p_update_date in varchar2,
p_job_number in varchar2 );

p_sum_column is an Table array. Now when we call it from anonymous block we have to give the array elements as you have shown in your example. My problem is I don't know upfront what will be the elements would be, only at runtime it will be determined whether I want to sum on an column or not. For eg. I'll call onto a table to find out whether there is a particular flag set. If its set to 1 then I'll sum on that column or else not. How can I possibly do this ? Or can it be at all done ? Please help.

Regards
Arindam

Tom Kyte

yes, you can do this -- arrays are just variables -- so in the same manner you pass in different queries, you can fill an array variable with anything you want and pass it in.

you just declare an array variable and fill it up? i don't see what is "hard" or "obscure" here.

maybe you post an example of what you tried and we'll take a look at it.


declare
l_var owa_sylk.owaSylkArray := owa_sylk.owaSylkArray();
begin
l_var.extend( number_of_columns_in_your_query );
for i in 1 .. l_var.count
loop
l_var(i) := 'N';
end loop;
-- now query your table and set the i'th element in the array to Y

the problem is YOU DO NOT have to give something like v_flag_list(1), ....

you have to FILL IN a variable v_flag_list (as demoed above) and then pass the single array v_flag_list

(please -- begging you -- use bind variables -- at the very very very least, use alter session set cursor_sharing=force!!!)

do you have a pl/sql programmer around? someone whose used arrays before?

But additionaly I would like to know if there is any possibility to put additional header information to the sheets.

Eg.

Create User : Scott
Created Date : 27-Aug-2003
Description : Testing

col1 col2 col3 col4 col5
----- ---- ---- ---- ----
A B C D E
F G H I J
.. .. .. .. ..

So in the above format could you please let us know how to add any type of headers as shown in the example( Created Date, Created User, Description etc).

Also is it possible to position the cell position to display contents eg cell(1,3) 1st row, 3rd column.

Set background color for heading, setting allignments etc.

I could not find any information on google.com about the SYLK format, could you please let me now.

Thankyou

Opening the file in EXCEL on a new session, not in the browser

Amanda, May 10, 2004 - 2:05 am UTC

I have a Web PL/SQL application. When I save the file it is written to the Unix box and not my work station. How can I open or spool this file to open in Excel on a new session and not just over the brwoser?

Tom Kyte
May 10, 2004 - 7:57 am UTC

that would be a virus like capability, wouldn't it.

the client must PULL the data -- we cannot just open up a client filesystem and have at it.


Hence you must use something, anything you want, on the client to write to the client. given that pretty much every client has a web browser - that might be a good choice.

Another Option

Need help converting owasylk.sql version 8i to 7.3.4

Hugo Francesco Monterroso Rivera, September 10, 2004 - 4:07 pm UTC

Hi Tom:

I read the suggestion you do to Mohd Ahmed on January 27, 2002. He ask you this: "What are your suggestions in order to have this working on 7.3.4.4 instead of 8i?"

You said him that he need to recode it using plsql index by tables types.

My question is: Do you have the package already compiled in 7.3.4 or with the changes you suggest? because i have some problem to compile it with no errors.

Thank you for your help.

"Oracle datas into Excell Sheet using pl/sql procedure in Oracle 8i",

Mousumi, July 26, 2005 - 8:12 am UTC

Hi Tom,
Using the package owa_sylk I can format font,width etc. of an excel file through Oracle.
If possible can you please give some idea or code to change background color,font color in the excel sheet.For Example,
using PL/SQL query I have to print the following infor mation in an excel sheet.

Employee Information

Emp. Name Ram Kishan Desig.
Jr. Software Developer
Emd. Id. 67823

Nor in the above example "Employee Ingormation","Emp. Name","Emp. Id","Desig" should be bold,in a color suppose red and the values should be in different color and not bold.Now the whole information should be in a block and its color should be yellow.

commit commits any outstanding transactions. commit_form (as I recall, it has been a decade since I did a form), POSTS all outstanding work from the form to the database and then commits.

WHAT IS THE DIFFERENCE BETWEEN COUNT(*) AND COUNT(1)

Tom Kyte
December 15, 2005 - 10:40 am UTC

count(1) is "wrong" and count(*) is correct.


count(*) says "i want to count the number of rows"

count(1) says "I want to count the number of 1's - for some reason".


count(*) is correct and proper.

count(1) is internally rewritten to be count(*) to fix it for those that don't use count(*) as they should...

HELP with Aligning UTL_FILE

Sandra Padron, May 16, 2006 - 1:49 pm UTC

I would really appreciate it.

Tom Kyte

well, this is just sort of "padding with spaces" isn't it?

It is not very clear what you mean - the reference to "use a file path" and "not using DBMS" is throwing me off the track here.


I believe you probably just want to use "lpad" to left pad a string to make it be "centered"?

The ExcelDocumentType generates an Excel XML document as its end product. Excel XML documents are automatically recognized by IE and the Windows OS as Excel documents, and are treated as such when opened (double click ...). The documents generated by the object work very well with Office 2003 (not with Open Office ...). The object gives the user the ability to create documents with the following features:

yeah, because utl_file is running on the SERVER

therefore, utl_file cannot dump to your PC, you would need a client program on the client to dump to the local file system


instead of utl_file.putline, use dbms_output.put_line and then you can use SPOOL from sqlplus to run the procedure and capture the output locally.

Instead of that you can use just the following simple code for the data generation in excel.

FILENAME UTL_FILE.FILE_TYPE;
FILENAME1 VARCHAR2(1000);

cursor c1 is
select OPTION , NOUN_NAME ,
CONFIG
from fp_cha
ORDER BY ORDER_BY;

BEGIN
FILENAME1:='SIRI_FP.slk';
FILENAME:=UTL_FILE.FOPEN('/tmp',FILENAME1,'W');
FOR I IN C1 LOOP
UTL_FILE.PUT_LINE(FILENAME,I.OPTION||' '||I.NOUN_NAME||' '||i.config);
EXIT WHEN C1%NOTFOUND;
END LOOP;
UTL_FILE.FCLOSE(FILENAME);
END;

The file will be created in the server where your database is installed.

use your powers of debugging to figure it out?

come on, you have the code (so do I - here we are equal)
you have the tables you are querying (you have them, I do not)
you have the query you are using (you have it, I do not)
you have the block of code that called this, you know the inputs (you do, not me)

so, it would seem you might be in a much better position to figure this out then I.

Loop in build_cursor

Gary, May 22, 2008 - 9:53 pm UTC

The 'subscript beyond count' issue is a problem in the BUILD_CURSOR function in the code in the original response. It has an uncontrolled loop (ie it has no exit condition, so either errors or continues until killed).
loop
  dbms_sql.bind_variable( c, n(i), v(i) );
  i := i + 1;
end loop;

can be replaced with :
WHILE i <= n.count LOOP
  dbms_sql.bind_variable( c, n(i), v(i) );
  i := i + 1;
end loop;

Also make sure you are giving values for all your bind variables.

.... look into this Query And Answer. ....

I had a really hard time getting past that sentence.


and then I hit this one:

... This Prodcedure is working .But my expected out put is different. ...


Here is my question to you:

I got in my car and it started, I expected it to work differently.
1) can't we use a missing key to start it?
2) I have lots of keys on my key chain
3) If I am missing a key it should beep
4) I cannot compete with that one. You win on #4 :)



Seriously - what sort of answer could I give

1) can a number variable contain null - absolutely, pretty much any variable could be NULL as long as it is not nullable - sure.

2) You can do it yourself
http://asktom.oracle.com/pls/ask/search?p_string=collection+arrays+java+store+procedure
or use jpublisher to publish an interface class
http://docs.oracle.com/docs/cd/B19306_01/java.102/b14188/toc.htm


3) define "miss a field in a procedure". If you mean "the variable MUST be passed and cannot be NULL


ops$tkyte%ORA10GR2> create or replace package types_pkg
  2  as
  3          subtype mynumber is number NOT NULL;
  4  end;

if you want to catch the error in your OWN procedure, you would have to validate the inputs yourself (else your scope never comes into play)

probably easiest to do with a wrapper procedure:

4) if you mean "to pass null" - which is not really 'missing a field' but rather 'passing null', no, do not use '' for null, use the keyword null for null

generate text files locally thru PL/SQL

Rahul, October 17, 2008 - 3:46 am UTC

Hi Tom,

What if we need to generate TEXT file on local/client machine not on the server.

Here after defining path for "utl_file_dir" parameter all file will be written on the server & some time everybody doesn't have access to server to fetch the generated file.

Can we generate text file locally instead of writing it on server thru PL/SQL

Look forward to hear from you.

you will not be using plsql. Plsql can only, will only, should only write to file systems available on the server.

PLSQL would be very "virus like" otherwise.


Think about it this way - would you expect a java routine running on an application server to be able to read and write YOUR pc's file system???


You need a client routine that can cannot to the database, run something on database, retrieve output and write it locally

(eg: a URL could do this, the client would 'execute' the URL locally, the browser being the client can use mod_plsql in the middle tier to run a stored procedure that generates output and send it back to the browser which can save it to disk (or open it, or display it, whatever)

Dynamic column

A reader, October 30, 2008 - 6:58 am UTC

hi,
I am dynamically trying to pass a particular column name to the select list of a select statement.

that is

@var = 'Col1'

so I need the following query

select col1 from tbl1

I will not know the column name is 'Col1' but the value will be in @var. How can I use it?

By the way I am using Oracle10g.
Thanks in advance.

Problem while saving the output into .xls from concurrent program

Alaka, July 10, 2009 - 7:32 am UTC

Hi,

As mentioned in the following link
http://garethroberts.blogspot.com/2007/10/excel-file-output-from-oracle.html

we have created concurrent program with output type as PCL and all the other steps including UPDATE MIME TYPE to get the output in .XLS.

But we have a problem here,
We are able to open the output as .pcl.xls format, but when we save the file the format is in .PCL only.
What could be the reason for this.?
How to resolve this issue? We need the output should be saved in .XLS instead of .PCL format.

Thanks
Alaka

How to retrieve the data from the Excel sheet using SQL SELECT statement within Oracle database.

I will be very thankful if anyone reply me.

K, February 08, 2013 - 2:18 pm UTC

Tom,
I granted execute rights for SYS.DBMS_SQL to "Sam" and ran the below sql but still getting an error. Can you please tell me what I am doing wrong? I replaced the directory location with an Oracle Directory name "DATADIR". I am using
Oracle 11.2.0.2.0 on Windows XP.

1 declare
2 output utl_file.file_type;
3 begin
4 output := utl_file.fopen( 'DATADIR', 'emp1.slk', 'w',32000 );

5 owa_sylk.show(
6 p_file => output,
7 p_query => 'select empno id, ename employee,
8 sal Salary, comm commission ' ||
9 'from scott.emp ' ||
10 'where job = :JOB ' ||
11 'and sal > :SAL',
12 p_parm_names =>
13 owa_sylk.owaSylkArray( 'JOB', 'SAL'),
14 p_parm_values =>
15 owa_sylk.owaSylkArray( 'MANAGER', '2000' ),
16 p_sum_column =>
17 owa_sylk.owaSylkArray( 'N', 'N', 'Y', 'Y'),
18 p_show_grid => 'NO' );
19 utl_file.fclose( output );
20* end;
21 /
declare

if you type

SQL> set role none;
SQL> select * from scott.emp;


does it work - if not:

http://asktom.oracle.com/pls/asktom/ASKTOM.download_file?p_file=6551289900368934430


it has nothing to do with dbms_sql, it has everything to do with the inability of your account to access scott.emp in a stored procedure.
