MYSQL使用inner join 进行 查询/删除/修改示例

复制代码 代码如下: --查询 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'

复制代码 代码如下: --查询 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 ; 复制代码 代码如下: -- 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' ; 复制代码 代码如下: --删除 DELETE FROM jx_lsjl jx INNER JOIN isa_gtxx gt ON jx.ckid=gt.gtbh WHERE gt.jgm='27010825' AND jx.jgm='27010825' ;
