原文地址：SQL中使用update inner join和delete inner join

 

 

Update XXX set XXX where 这种写法大家肯定都知道，才发现update和delete居然支持inner join的update方式，太神奇了。分享段示例代码：

view source
print?
1
update tb_User 
2
set pass=''
3
from tb_User usr 
4
inner join tb_Address addr on usr.nAddressFK = addr.nAddressID 
5
where 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

注意蓝色部分。
