Question

查询：

UPDATE EMPLOYEE AS E 
INNER JOIN EMPLOYEE_TEL AS T ON E.EMP_NUMBER = T.EMP_NUMBER
   SET E.FIRST_NAME = @fname
      ,E.MID_NAME = @mname
      ,E.INITIALS =@initilas
      ,E.SURNAME = @sname
      ,E.GENDER = @gender
      ,E.CIVIL_STATUS = @CS
      ,E.DOB =@datetime 
      ,E.NIC_NUMBER = @nic
      ,E.ADDRESS_LINE1 =@adline1
      ,E.ADDRESS_LINE2 = @adline2
      ,E.ADDRESS_LINE3 = @adline3
      ,E.EMAIL = @email
      ,E.DESG_NO =@designo
      ,E.BASIC_SALARY = @sal
      ,E.TITLE = @title
      ,T.TELEPHONE=@tel
WHERE E.EMP_NUMBER=@empnum

我在这个SQL Server中尝试过，但它出现了错误

'Msg 156，Level 15，State 1，Procedure SPUPDATEEMP，Line 21
关键字“AS”附近的语法不正确。

我找不到错误。这是错的吗？

Answer 1

UPDATE EMPLLOYEE
   SET FIRST_NAME = @fname
      ,MID_NAME = @mname
      ,INITIALS =@initilas
      ,SURNAME = @sname
      ,GENDER = @gender
      ,CIVIL_STATUS = @CS
      ,DOB =@datetime 
      ,NIC_NUMBER = @nic
      ,ADDRESS_LINE1 =@adline1
      ,ADDRESS_LINE2 = @adline2
      ,ADDRESS_LINE3 = @adline3
      ,EMAIL = @email
      ,DESG_NO =@designo
      ,BASIC_SALARY = @sal
      ,TITLE = @title
WHERE EMP_NUMBER=@empnum

UPDATE EMPLOYEE_TEL
    SET TELEPHONE=@tel
    WHERE EMP_NUMBER=@empnum

Answer 2

进行JOINS时，您不需要使用“as”来为表名设置别名。

但是，在进行更新时，您不能像想要的那样为名称添加别名。

UPDATE E
FROM Employee

Answer 3

您要做的是一次更新两个表 - 您无法在SQL Server中执行此操作 - 您必须将其拆分为两个单独的更新：

UPDATE EMPLOYEE 
SET 
  FIRST_NAME = @fname,
  MID_NAME = @mname,
  ..... 
  TITLE = @title
WHERE 
   EMP_NUMBER = @empnum

UPDATE EMPLOYEE_TEL 
SET 
   TELEPHONE = @tel
WHERE 
   EMP_NUMBER = @empnum
