Home -> Community -> Mailing Lists -> Oracle-L -> RE: SQL comparison addition:
SQL> select sys_context('userenv','session_user'),
2 dump(sys_context('userenv','session_user')), a.reports_login,
3 dump(a.reports_login)
4 from global.client_dim a
5 WHERE sys_context('userenv','session_user') = trim(a.REPORTS_LOGIN);
SYS_CONTEXT('USERENV','SESSION_USER')
And
1 SELECT count(*)
2 FROM global.client_dim a
3* WHERE sys_context('userenv','session_user') =
trim(a.REPORTS_LOGIN)
0
I'm going to open a tar on this.
I will email the resolution. ...and check for any more suggestions! :)

Produces some output.
Your original query does not return anything.
1 SELECT count(*)
2 FROM global.client_dim a
3* WHERE sys_context('userenv','session_user') =
trim(a.REPORTS_LOGIN)
The obvious differences here are:
. TRIM function
. probably when you've tried to launch the original query you had pofile
functions enabled, when you tried it second time it was disabled.
. query rewrite is used (could be, right?)
Could you please check the second and third items?
