我有一个名为 Home 的 View :
CREATE VIEW `skohr`.`Home` AS
Select Song_OID, Song_Name, Album_Name, Artist_First_Name, Artist_Last_Name, Band_Name, Genre, Album_Art_File_Path
From Song, Album, Artist, Track_Number, Made
Where Song_OID = Track_Number.Song_OID_FK AND Album_OID=Track_Number.Album_OID_FK AND Album_OID=Made.Album_OID_FK AND Artist_OID=Made.Artist_OID_FK
ORDER BY Song_Name Asc
我在 View 上运行了以下查询以获得我想要的表:
Select DISTINCT * From Home LEFT OUTER JOIN (SELECT * FROM Song_Setting, user WHERE User_OID=User_OID_FK) AS UserSongs
ON Song_OID=Song_OID_FK
如何将两个单独的查询合并为一个以创建单个 View ？
最佳答案
尝试只创建 View
CREATE VIEW `skohr`.`MyNewView` AS
Select DISTINCT * From Home h
LEFT OUTER JOIN Song_Setting x
ON h.Song_OID_FK = x.Song_OID
INNER JOIN user u
ON u.User_OID = x.User_OID_FK
关于mysql - 结合 SQL View 和 Left Outer Join 查询，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13692596/
