I presume, your query is running out of indexes. Run the explain plan and
check if Oracle performs any full scan into a table.
Then, create an index for that particular case. If for any reason, Oracle
doesn't use the index created, apply a hint ( /+ /) into your SQL, meaning
that your going to force the engine to use it as a part of your execution
plan.
If the above still without working, I suggest to check your query, you might
be able to reformulate your query by analyzing the product Cartesian that
would return to you.
HTH,

Subject: Query question
Hello gurus
please help
I am running following query
This takes forever to complete.
select pay.gl_date from
noetix_sys.noetix_current_period off
2 ,gl.gl_sets_of_books sob, gl.gl_periods per,
3 ar.ar_payment_schedules_all pay
4 where
5 pay.gl_date between per.start_date and
per.end_date
6 and per.period_set_name||'' =sob.period_set_name
7 and per.period_type = sob.accounted_period_type
8 and sob.set_of_books_id=26
9 and off.application_id=222
10 and off.period_type=sob.accounted_period_type
11* and off.set_of_books_id=26
Now if I takeout following line
and off.period_type=sob.accounted_period_type
it works
the column "off.period_type" and
"sob.acoount_period_type" are both not null
varchar2(15) type.
Could anybody has some idea, why its doing that.
thank you very much
Please help
