sql连接问题

Question

我有以下表格

nid    timestamp   title

82  1245157883  Home
61  1245100302  Minutes
132    1245097268  Sample Form
95  1245096985  Goals & Objectives
99  1245096952  Members

和

        pid     src         dst                                     language



        70  node/82         department/34-section-2      
        45  node/61/feed    department/22-section-2/feed     
        26  node/15         department/department1/15-department1    
        303 node/101        department/101-section-4 

这些是表的片段,并且缺少其余的数据(它们都非常大),但我试图将第二个表中的dst列加入到第一个表中.它们应匹配"nid",但第二个表有节点/ [nid],这使得它更复杂.我也想忽略以"feed"结尾的那些,因为我不需要它.

非常感谢

编辑:我不好意思没有提到这个,但第一个表是一个sql结果来自

select nid, MAX(timestamp) as timestamp, title from node_revisions group by nid ORDER BY timestamp DESC LIMIT 0,5

第二个表的名称为"url_alias"

Answer 1

尝试

select * from table1 inner join table2 on src=concat('node/',nid)

编辑以反映OP中的更改

select `nid`, MAX(`timestamp`) as `timestamp`, `title` from `node_revisions` inner join `url_alias` on `src`=concat('node/',`nid`) group by `nid` ORDER BY `timestamp` DESC LIMIT 0,5
