我有2张桌子 - 员工桌和Emplabor桌子 - 员工表:
Employee Table
EMPLOYEEID (primary key)
,EMPLOYEENO
,EMPLOYEENAME
,LABORCODE
,LOGINNAME
,STARTDATE
,ADDRESS0
Emplabor表:
EMPLABORID (primary key)
,LABORCRID
,EMPLOYEEID
,LABORCODE
我想更新Emplabor的Employee表中的LABORCODE列 这就是我所做的::
UPDATE dbo.EMPLOYEE
SET LABORCODE =dbo.EMPLABOR.LABORCODE
FROM dbo.EMPLABOR
WHERE dbo.EMPLOYEE.EMPLOYEEID=dbo.EMPLABOR.EMPLOYEEID
这项工作还可以更新我的所有员工的LABORCODE我已添加到数据库中,但是当我在Employee Table中添加一名新员工并从Emplabor Table中选择LABORCODE给该员工时,它就是dosn&#t; t在该员工的EMployee表中找到了LABORCODE
答案 0 :(得分:0)
使用加入:
UPDATE emp
SET LABORCODE = empl.LABORCODE
FROM dbo.EMPLOYEE emp
JOIN dbo.EMPLABOR empl
ON emp.EMPLOYEEID = empl.EMPLOYEEID
