7张表怎么同时比对其中的相同内容
select * from table1,table2
where table1.sfzh=table2.sfzh;
如果有7张表怎么写。
------解决方案--------------------
- SQL code
select * from table1 inner join table2 on table1.sfzh=table2.sfzh inner join table3 on table1.sfzh=table3.sfzh inner join table4 on table1.sfzh=table4.sfzh inner join table5 on table1.sfzh=table5.sfzh inner join table6 on table1.sfzh=table6.sfzh inner join table7 on table1.sfzh=table7.sfzh
