                                         FROM dbo.Table2 
                                         WHERE RefRolleId =@Id)

Answer 1

just remove IS and it will work (this is just to answer your question directly and nothing else (eg performance improvement))

SELECT dbo.Table1.*,
       CAST (CASE WHEN Table1.Id  IN ( SELECT Id 
                                         FROM dbo.Table2 
                                         WHERE RefRolleId =@Id) 
              THEN 0 ELSE 1 END AS bit) AS selected
FROM   dbo.Table1
