更新A表的信息,使A表的a数据=B表的b数据。这个算是比较简单的一个查询语句,但我总是搞错。
写为:(该语法在Access里是成立的)
update xsjbdab inner join adab on xsjbdab.xh=adab.xh
set xsjbdab.byrq=adab.byrq
where xsjbdab.xh like '2008%'
set xsjbdab.byrq=adab.byrq
where xsjbdab.xh like '2008%'
正确应为:
update xsjbdab
set xsjbdab.byrq=adab.byrq
from xsjbdab inner join adab on xsjbdab.xh=adab.xh
where xsjbdab.xh like '2008%'
set xsjbdab.byrq=adab.byrq
from xsjbdab inner join adab on xsjbdab.xh=adab.xh
where xsjbdab.xh like '2008%'
