Hi
 

It's an Insert .... select.
The select part is spending exactly the same amount of time(13 secs) from the extended trace.
 
 

Rows  Operation
 

0  LOAD TABLE CONVENTIONAL (crC1112 pr4448 pw=0 time11385671 us) 43,564     FILTER (crB7284 prD8 pw=0 time572425 us)
 

Thanks

Hi Antony,
Have you enabled entended sql trace to check the what's the major component of the current 6-7 minutes. Unless identifying what's responsible for the response time, we can only guess.

what's the method to insert the rows, are inserted in a single insert...select... statment, in by inserting 45,000 times, in such a case,  you may want to try the array insert method, the forall statment.
