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

Use 'Exists' which returns either 0 or 1.

The query will be like:

SELECT EXISTS(SELECT * FROM USER WHERE UserID = 20070022)
