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
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
