CTE的语法无效

Question

世界上可能出错的地方，语法看起来不错：

With photos(PhotoID, MemberID) as
(
    select  photoID,
            memberID
    from MemberPhotos
)
select PhotoID, MemberID from photos

Answer 1

如果CTE来自其他查询，则应在semi-colon关键字之前添加WITH。

;With photos(PhotoID, MemberID) as
(
    select  photoID,
            memberID
    from MemberPhotos
)
select PhotoID, MemberID from photos
