Return Boolean Value on SQL Select Statement

Question

How to return a boolean value on SQL Select Statement?

I tried this code:

SELECT CAST(1 AS BIT) AS Expr1
FROM [User]
WHERE (UserID = 20070022)
         


        

Answer 1

select CAST(COUNT(*) AS BIT) FROM [User] WHERE (UserID = 20070022)

If count(*) = 0 returns false. If count(*) > 0 returns true.
