SQL Server - IN-klausul med flere felter

Ikke som du har skrevet. Du kan kun returnere et enkelt felt eller type for IN at arbejde.

Fra MSDN (IN ):

test_expression [ NOT ] IN 
    ( subquery | expression [ ,...n ]
    ) 

subquery - Is a subquery that has a result set of one column. 
           This column must have the same data type as test_expression.

expression[ ,... n ] - Is a list of expressions to test for a match. 
                       All expressions must be of the same type as 
                       test_expression.

I stedet for IN , kan du bruge en JOIN ved at bruge de to felter:

SELECT U.* 
FROM user U
  INNER JOIN userType UT
    ON U.code = UT.code
    AND U.userType = UT.userType
