t-sql
Update XXX set XXX where 这种写法大家都知道，
这里update和delete支持inner join的update 的定法
update tb_Userset pass=''from tb_User usrinner join tb_Address addr on usr.nAddressFK = addr.nAddressIDwhere usr.id=123
update的格式是
update t1 set t1.name=’Liu’ from t1 inner join t2 on t1.id = t2.tid
delete 语句也是类似
delete from t1 from t1 inner join t2 on t1.id = t2.tid
