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.
