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
