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,
