实现的功能：
视图的创建：
--两个表的查询 select a.*,b.* from [dbo].[Department] as a inner join [dbo].[UserManager] as b on a.DepartmentId=b.DepartmentId --三个表的查询 select a.*,b.*,c.* from [dbo].[Department] as a ,[dbo].[UserManager] as b, [dbo].[tbRose] as c where a.DepartmentId=b.DepartmentId and c.RoseID=b.RoleId --创建视图 查询中不能有相同的列 CREATE VIEW UserInfoView AS select a.[DepartmentName],b.*,c.[RoseName] from [dbo].[Department] as a ,[dbo].[UserManager] as b, [dbo].[tbRose] as c where a.DepartmentId=b.DepartmentId and c.RoseID=b.RoleId select * from [dbo].[UserInfoView]
直接在视图中修改员工状态：
SELECT a.DepartmentName, b.UserId, b.LoginName, b.UserName, b.Password, b.DepartmentId, b.RoleId, b.Birthday, b.Mobile,
b.Email, b.Photo, b.Address, b.LastLoginDate, b.Sex, b.DisplayOrder, b.Sate, c.RoseName,
CASE b.sate WHEN ‘True‘ THEN ‘正式员工‘ ELSE ‘试用期员工‘ END AS StateName
FROM dbo.Department AS a INNER JOIN
dbo.UserManager AS b ON a.DepartmentId = b.DepartmentId INNER JOIN
dbo.tbRose AS c ON b.RoleId = c.RoseID
