insert 语句问题?
use my_oa
go
insert into tb_AA (InfoId)
select InfoId
from tb_BB
where tb_AA.AName = tb_BB .BName


插入表tb_AA时失败，错在哪里？该如何改呢？


[解决办法]
insert into tb_AA (InfoId) values(你的值)

[解决办法]
接分
[解决办法]
insert into tb_AA (A.InfoId)
select B.InfoId
from tb_BB B Left Join tb_AA A
On A.AName = B.BName

[解决办法]
use my_oa
go
insert into tb_AA (InfoId)
select tb_AA.InfoId
from tb_BB,tb_AA
where tb_AA.AName = tb_BB.BName


这样就可以了

[解决办法]
insert into tb_AA s(InfoId)
select InfoId
from tb_AA ,tb_BB
where tb_AA.AName = tb_BB .BName
[解决办法]
insert into tb_AA (A.InfoId)
select B.InfoId
from tb_BB B Left Join tb_AA A
On A.AName = B.BName
--------------------
正解
[解决办法]
insert into tb_AA (A.InfoId)
(select B.InfoId
from tb_BB B Left Join tb_AA A
On A.AName = B.BName)

[解决办法]
update 原理是一样的，可以用下面的语句


Update tb_AA set InfoId = B.InfoId
from tb_BB B Left Join tb_AA A
On A.AName = B.BName
