I stand corrected: tracing probably won't work because the cr and cu values would wrap.

Just kidding. :)

BEFORE YOU TRY disabling indexes (or anything else for that matter), I strongly advise you to trace the program so you can see where it spends its time. Even if you have guessed the solution correctly, tracing will provide the enormous value of allowing you to quantify exactly how much ground you will have gained.

Then there's always the chance that you haven't guessed the solution correctly, in which case you'll need the trace data to help you divine the actual right solution.

HI ,

I have noticed that both deleting and inserting is too slow (about five hours to insert 40000 rows !!!!),
this may be because i have more than 40 INDEX ON THIS TWO tables,I will
try to disable them before i run my insert statement .

Thanks,
