Lines 11-18 were not executed at all. This would have been due to the
filter operation on line 4. If you check the execution plan with
dbms_xplan.display_cursor then you will get the predicates section
(something that SQL Live Monitor reports are lacking), you should see what
it says about line 4 for clues.
Hope that helps,
Andrew

Hi Listers,
I have one quick question. Does the blank column values mean those
operations are not called and do they mean 0 records returned.
