refactor SELECT WHERE AND OR EXISTS :     SELECT *
    FROM a
    WHERE
    a.field=@fieldValue
    AND
    (
        YEAR(a.myDate)=@y
        OR EXISTS
        (
        SELECT *
        FROM b
        WHERE b.Id=a.Id
        )
        OR EXISTS
        (
        SELECT *
        FROM c
        WHERE c.Id=a.Id
        )
    ...
    )
How can this be rewritten in a simpler way ?
