Hi Guru,
When I ran my adhoc script below it generated only 45000 reads or 4
seconds but when I wrapped it into procedure it took about two minutes
or millions of reads. The parameters calling both adhoc and proc are
indeed the same. I'm pretty 99.9% sure that the proc does not recompile
because I don't mix up between DDL and DML, no temp tables or any thing
to cause proc to recompile. The big difference is adhoc used index scan
for 45% but proc used bookmark lookup for 75%. Why it's so difference
since they both returned the same results?
Please help...
