Hi Tom

I hit a problem, when gen DDL statement using DDL command in sqlcl tools. Follow with my environment:

(1) Redhat
(2) Oracle Database 12c Standard Edition Release 12.1.0.2.0 - 64bit Production
(3) SQLcl: Release 4.2.0.17.097.0719 Production

In the database schema , it have a view and it have 2 trigger depend on it. When I use 'DDL XXX VIEW' command, it will gen the VIEW and it's dependence triggers DDL statement. It issue is the trigger DDL gen order will be difference, some times is :
VIEW XXX DDL -> TRIGGER A DDL -> TRIGGER B DDL.
VIEW XXX DDL -> TRIGGER B DDL -> TRIGGER A DDL.

Because we have a batch job to gen all objects DDL and compare have any changes everyday. This issue cause incorrect compare result.

Have any setting to fixed objects DDL statement gen order OR disable gen dependents objects










and Connor said...

I've had a look and the order does not appear to be deterministic.

I've asked the Product Manager for SQLcl to take a look.

I'll update this answer when I get more information.

Looks like a 22.2 regression - I'll log a bug

Liquibase and SQLCL

Rajeshwaran, Jeyabal, September 06, 2022 - 4:59 am UTC

Thanks for helping us on that.

Here is another one from using Liquibase with the SQLCL (22.2) version connecting to an Oracle database 21c (21.3)

got two schema A (source) and B (target)

on the source schema did this
a@PDB1> create table t1(x number);
 
Table T1 created.
 
a@PDB1> create table t2(x number, y date);
 
Table T2 created.
 
a@PDB1>
a@PDB1> create or replace procedure demo_call
 2 as
 3 l_cnt number;
 4 begin
 5 select count(*) into l_cnt from t2;
 6 dbms_output.put_line('Table t2 got '||l_cnt||' rows..');
 7 end;
 8* /

Action successfully completed please review created file demo_call_procedure4.xml
a@PDB1>

However on the target database, when we executed the "UPDATESQL" command to verify the sql, saw this.
(see the below highlighted "<========" for details about "statement terminator", instead of "/", it was like this "/;" )
and due to that, when we run the "UPDATE" command from Liquibase it errored like below.

Liquibase and SQLCL

Rajeshwaran, Jeyabal, September 07, 2022 - 5:07 am UTC

Team,

Please ignore my above request, reached Oracle support and they confirmed it as a bug.

Here is the bug details and the workaround from Oracle support on this.
Its a bug and already tracked by SQLcl Development

Bug 34449082 : SECOND LB GENSCHEMA COMMAND IN SINGLE SQLCL SESSION BREAKS XML FILE & ADDS /

As a workaround do a genschema without -split.


Just verified the workaround and it works in the above case. Thanks.

SQLCL and the SPOOL command output.

Rajeshwaran, Jeyabal, September 13, 2022 - 5:07 am UTC

Team,

see the below, spool command output from SQLCL is not similar to the SQL*Plus. why the command inputs are not available in the spool file generated from SQLCL, where as the SQL*Plus got those.

From SQLCL (version 22.2.1) got this

Known bug

BUG 34601609 - SQLCL SPOOL OUTPUT IS NOT CONTAIN SQL STATEMENTS

Fixed in an upcoming release

SQLCL and Liquibase on Reference Partitioned tables.

Rajeshwaran, Jeyabal, September 13, 2022 - 5:11 am UTC

Team,

we got few application tables that got reference partitioned in our Development database.
Testcase crafted below looks close to our application model.

grant connect,resource,create session to a identified by "a";
alter user a default tablespace users quota unlimited on users;

grant connect,resource,create session to b identified by "b";
alter user b default tablespace users quota unlimited on users;


conn a/a@pdb1

create table t1(x number generated by default as identity, y date,
       constraint t1_pk primary key(x) )
partition by range(y)
interval( numtoyminterval(1,'month') )
( partition p1 values less than
       ( to_date('01-jan-2022','dd-mon-yyyy') ) 
);

create table t2(x1 number generated by default as identity,x2 number not null, 
       constraint t2_pk primary key(x1) ,
       constraint t2_fk foreign key(x2)
             references t1(x) )
partition by reference(t2_fk);          

lb genschema -label run1

conn b/b@pdb1
tables
lb update -changelog controller.xml -label run1
tables 

conn a/a@pdb1 

alter table t2 add Z number;
lb genschema -label run2

conn b/b@pdb1
lb updatesql -changelog controller.xml -label run2


that final "lb updatesql" command produces the following ddl

-- Changeset t2_table.xml::cadc02c572f3991d731e71330e63a98857c6c54d::(A)-Generated
ALTER TABLE "T2" ADD ("Z" NUMBER)
/
  ALTER TABLE "T2" MODIFY ("X1" GENERATED BY DEFAULT AS IDENTITY
)
/
  ALTER TABLE "T2" DROP CONSTRAINT "T2_FK"
/
  ALTER TABLE "T2" ADD CONSTRAINT "T2_FK" FOREIGN KEY ("X2") REFERENCES "T1"("X") ENABLE;


dropping that FK is not possible, since we got reference partitioned using this FK constraint

so got a couple of question, please help us to clarify.
1) why do we get modify command on identity column here (what is the need for this ddl? (ALTER TABLE "T2" MODIFY ("X1" GENERATED BY DEFAULT AS IDENTITY) )
2) why the Liquibase is trying to drop and recreate the FK constraint, for a simple add column on the source schema?

LB UPDATE command ended up with error like this, any work around or fix available for this ?

b@PDB1> lb update -changelog controller.xml -label run2
