使用来自不同表的WHERE语句从SQL Server中删除行

Question

我需要根据两个表中的混合where语句从表中删除一些行.

我试过这个:

delete from tblI t1, tblS t2 
where t2.rcode = 'ALA' and t1.sid > 5

但我得到一个语法错误.请帮我解决这个问题

将其更改为JOINS:

delete from tblI
inner join tblS
on tblI.sourceid = tblS.sourceid
where tblS.rcode = 'ALA' and tblI.sourceid > 5

但有些事情仍然是错误的,请帮助.

你必须告诉它要删除哪个表.

delete t1
from tblI t1 
join tblS t2  on t1.sid = t2.sid
where t2.rcode = 'ALA' 
and  t1.sid > 5
