报错：子查询注意！

SELECT @JS_ID = A.ID,
        @JSHM = A.JSHM,
        @JS_MC = A.JS_MC,
        @XY_DM = A.XY_DM,
        @RS = A.RS
    FROM(select ID,JSHM,JS_MC,XY_DM,RS
     FROM F_Get_ZYBJ_JXB_JSXX(@ID_ZYBJ_KKKC_JXB,@ID_1,@XND_Q,@XND_Z,@XNXQ)
     where JSLX_DM = @JSLX_DM
     and DXBZ >= @BJSL)AS A
    WHERE A.ID NOT IN(dbo.aa(@i,@num,@PK_JS_JG_Array)) 之前没有写 “AS  A” 报错，而在where语句中若要用到子查询则不需启别名。
