EF 映射没有主键的视图

Posted 2021-01-26 coffeeeddy

在数据库中先把视图建好，

然后在右键视图->编写视图脚本->CREATE->新查询窗口

在光标出添加主键

1 CREATE VIEW [dbo].[V_ShareData]
2 AS
3 SELECT   ISNULL(NEWID(), ‘d1e57ca7-6eee-495a-be13-73d5e7d51f36‘) AS Id,dbo.ShareData.*, dbo.Tag.TagName, dbo.[User].UserName
4 FROM      dbo.Tag INNER JOIN
5                 dbo.ShareData ON dbo.Tag.TagId = dbo.ShareData.TagId INNER JOIN
6                 dbo.[User] ON dbo.ShareData.UserId = dbo.[User].UserId

然后在视图中就有主键，可以在EF中映射了
