   --查詢
   SELECT tp.tp_id, tp.tpmc, tp.leveid, tp.tpdz, tp.jgm, tp.scsj, tp.pbzyid, tp.ksbfsj, tp.jsbfsj, tp.status, tp.tpbz   FROM  qdgl_tupian tp INNER JOIN  qdgl_pqb  pq
    ON  tp.tp_id=pq.tpid  WHERE  pq.bfjgm='27010825'  AND  ps_bfsj >= '2013-01' AND  ps_bfsj< 2013-05-31  ;

  -- 修改
    UPDATE jx_lsjl jx INNER JOIN isa_gtxx gt ON jx.ckid=gt.gtbh  set jx.ckid=gt.gtid WHERE gt.jgm='27010825' AND jx.jgm='27010825' ;

   --刪除
    DELETE jx FROM  jx_lsjl jx INNER JOIN isa_gtxx gt ON jx.ckid=gt.gtbh    WHERE gt.jgm='27010825' AND jx.jgm='27010825' ;
