Hi,
Regards,Amit S
In one of the queries TKProof shows, most time is spent in accessing a table thousands of times inside NOT EXIST condition.
I am looking for your inputs if it's a promising idea to replace NOT EXIST with the LEFT OUTER JOIN and IS NULL condition?
Any inputs in this regard are appreciated.
