I just found that the query in question works ... In following conditions ...

using case structure instead of DECODE
by running the report with cursor_sharing=3Dexact or providing cursor_sharing_exact hint at statement level
Running the select with rule hint.

BTW it is not datatype conversion issue, the actual decode statement is as follows ...

"and decode('C8','C8','237','0') =3D '237'"
=20

It is becoming obvious to me that this is an optimizer issue. I'll be digging further ... =20

Hi again

Sorry, haven't looked into it. Since we already changed everything to =
=3D

CASE on 9.2.0.4.0. The reason wasn't a bug but to be coherent with the =
=3D

usage of DECODE / CASE. We agreed upon ANSI style stuff (INNER JOIN, =3D CASE blahblah) since 2 developers have a SQL Server background and seem
=3D to comprehend that faster (no pun intended, they're great).
