Question

我有三张桌子：

CREATE TABLE tblEmployee1  
(  
 Id int Primary Key,  
 Name nvarchar(30),  
 Gender nvarchar(10),  
 DepartmentId int  
) 

CREATE TABLE tblDepartment1  
(  
 DeptId int Primary Key,  
 DeptName nvarchar(20)  
)

CREATE TABLE tblEmployee  
(  
 Id int Primary Key,  
 Name nvarchar(30),  
 Gender nvarchar(10),  
 DepartmentId int,  
 DeptName nvarchar(20)
)

其中两个人加入了一个观点：

Create view ViewEmployeeDetails1  
as  
Select Id, Name, Gender,DepartmentId, DeptName  
from tblEmployee1  
join tblDepartment1  
on tblEmployee1.DepartmentId = tblDepartment1.DeptId

我创建了触发器，以便在更新视图时使用数据触发器触发并使用视图中的数据更新第三个表（tblEmployee），而不使用重复记录。触发剂量似乎在更新视图时将值插入到tblEmployee。你能不能帮我解决问题，不知道它的发展方向我的触发器在下面先谢谢。

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER [dbo].[Update_Employee]
   ON  dbo.ViewEmployeeDetails1 
   INSTEAD OF UPDATE
AS 
BEGIN
insert into dbo.tblEmployee  
([Id], [Name], [Gender], [DepartmentId], [DeptName])

SELECT  i.[Id],i.[Name], i.[Gender], i.[DepartmentId], i.[DeptName] 

        FROM   dbo.ViewEmployeeDetails1  t
       INNER JOIN i
        ON t.Id = i.Id 
        WHERE i.Id IS  NOT NULL
end

Answer 1

表格中没有DeptName，所以您似乎想要：

insert into dbo.tblEmployee  ([Id], [Name], [Gender], [DepartmentId])
    SELECT  i.[Id], i.[Name], i.[Gender], i.[DepartmentId]
    FROM inserted i
    WHERE i.Id IS  NOT NULL
end;

在sql视图上更新数据时更新第三个表
