count返回的是int类型，我这个赋值0不是int类型吗

SELECT
        COUNT(*) AS fNUM
        ,'0' fSUM
        ,P.FDWID AS fOwerOrgID
    FROM
        ECON_Proj_MultiBusiness S
            LEFT JOIN BC_MT_Project P
                ON P.FID = S.fProjectID
    WHERE
        S.fState = '在施'
    GROUP BY
        P.FDWID
UNION ALL
SELECT
        '0' fNUM
        ,COUNT(*) fSUM
        ,P.FDWID AS fOwerOrgID
    FROM
        ECON_Proj_MultiBusiness S
            LEFT JOIN BC_MT_Project P
                ON P.FID = S.fProjectID
    WHERE
        S.fState = '在施'
        AND S.FSFQDZRS = '是'
    GROUP BY
        P.FDWID;
