本文为大家介绍下使用inner join 进行查询/删除/修改，具体实现如下，学习mysql的朋也可以学习下，希望对大家有所帮助
--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 ;
-- 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' ;
--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' ;
