Question

How to select a result of comparison operator as a field with type BIT?

How it does work in C#:

bool isGreater = FieldA > FieldB;

How it doesn't work in T-SQL:

SELECT (FieldA > FieldB) AS BIT FROM t

How to write such task properly?

CASE
    WHEN FieldA > FieldB THEN 1
    ELSE 0
END AS [BIT]
