Hi Tom,

I have created a Table say table-A and created a synonym TableAX.

When I say Truncate table table-A it is truncating without any problem. But if I give Truncate table TableAX (Synonym) it says table or view doesn't exist. I was surprised by this (I never used synonym before in Truncate statement, but this time I need to use synonym in Truncate). When we use synonym in all other place, why not Oracle doesn't allows us to use synonym in Truncate Statement ?

Is it done purposely not to use Synonym in Truncate or is it a bug?

Thanks,

Senthil.

A synonym can only be used with some commands. See

</code> http://docs.oracle.com/cd/A81042_01/DOC/server.816/a76989/ch4g8.htm#3702 <code>

For DDL, this is specifically:


AUDIT
NOAUDIT
GRANT
REVOKE
COMMENT

so, truncate does not stand alone:

tkyte@TKYTE816> create procedure p as begin null; end;
2 /

Procedure created.

tkyte@TKYTE816> create synonym p_syn for p;

Synonym created.

tkyte@TKYTE816> alter procedure p compile;

Procedure altered.

tkyte@TKYTE816> alter procedure p_syn compile;
alter procedure p_syn compile
*
ERROR at line 1:
ORA-04043: object P_SYN does not exist


tkyte@TKYTE816> exec p;

PL/SQL procedure successfully completed.

tkyte@TKYTE816> exec p_syn;

PL/SQL procedure successfully completed.

is another example....
