Subj:   SQL Problem and CASE WHEN statements
 
From:   Rick Davis

All,

I'm facing new problem in one of my SQL(INSERT/SELECT) target table is empty , SQL has couple of left outer and inner joins , it works fine every night , it INSERTs some thousand rows in few minutes. Suddenly from yesterday its running for long time , select count(*) for the same join works fine , but actually it has couple of CASE WHEN statements in SQL , does these CASE statements in SELECT degrades performance?


Thanks,

Rick
