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)

Possibly something along these lines:

SELECT CAST(CASE WHEN COUNT(*) > 0 THEN 1 ELSE 0 END AS BIT)
FROM dummy WHERE id = 1;
