Hi friendsHow to Exclude Records using join . I usually do not in
Example: I have a Table A and Table B
I want to exclude all the loans from table A where Table B has condition with COLUMN_B = "Y"
example In not in : select * from TableA where ColumnA not in ( Select * from TableB where ColumnA='Y')
Thanks,
Komal
Probably something like this:
SELECT *
FROM TableA a
INNER JOIN TableB b ON a.LoanID = b.LoanID
WHERE b.ColumnA <> 'Y'
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
