What is the difference between two queries: 1. SELECT * FROM table WHERE 1=1; 2. SELECT * FROM tab..

Answer / hitesh taneja

When we use 1=1 or any condition which is always going to
true, it will take extra bit of time bcoz it is a condion so
althouth the output of the query will be the same the
performance time will be bit higher with condition.

Hi SQL gurus,

My team is having a problem in sql server. when user slects
