sql 用INTERSECT 删除交集 2个表结构相同那么取交集是 select * from table1 INTERSECT select * from table2 如何用 INTERSECT 快速删除交集,我想在table1中删除table1和table2的交集。 不用delete from table1 where field* in (select field* from table2) 或者delete from table1 where exist (select * from table2 where field*=table1.field*)之类的需定位到字段匹配的sql。 谢谢!
