怎么样在SQL中查找某几个字段完全一样的数据?
有以下一个表
movestar(id,name,title,address),内容为:
现在要查找所有具有相同的title和address的人
复制代码 代码如下:
select star1.name,star2.name,star1.title,star1.address
from movestar as star1,movestar as star2
where star1.title = star2.title
and star1.address = star2.address
and star1.name < star2.name;
from movestar as star1,movestar as star2
where star1.title = star2.title
and star1.address = star2.address
and star1.name < star2.name;
结果:
要点:使用了<,假如用<>则会将内容重复列出
以上就是SQL中查找某几个字段完全一样的数据的全部内容,希望能给大家一个参考,也希望大家多多支持路饭。
