如何使用带有Having 子句的Result 列

Question

我有一个存储过程，

我想对列 IsUserFruitEater 和 IsUserOnSite 使用 HAVING 子句，但它说列不存在。

不确定如何使用列，必须有一种方法可以使用存储过程结果的列...

ALTER procedure [dbo].[Risks_GetFruitCratesForUser]
(
    @UserID VARCHAR(200),
    @URLFilter varchar(256)
)
AS
SELECT DISTINCT 
    Fruits.*
    ,FruitsCrate.* dbo.IsUserRegularFruitEater(@UserID, FruitsCrate.FutureID) AS 
    IsUserFruitEater
    ,dbo.IsUserOnSite(@UserID, FruitsCrate.FID) AS IsUserOnSite
    ,COALESCE(doThis.deeraw, - 1) AS deeraw
    ,COALESCE(doThat.HeroSheema, - 1) AS HeroSheema
    ,Jootey.deeraw * Jootey.HeroSheema AS BigBang
FROM someTable....
WHERE blahblah NOT NULL
    AND blahblah2 LIKE "abc"
HAVING Min(IsUserFruitEater) > 0
    OR Min(IsUserOnSite) > 0

Answer 1

使用子查询和where 子句：

SELECT t.*
FROM (SELECT DISTINCT Fruits.*, FruitsCrate.*
            dbo.IsUserRegularFruitEater(@UserID, FruitsCrate.FutureID) AS IsUserFruitEater,
            dbo.IsUserOnSite(@UserID, FruitsCrate.FID) AS IsUserOnSite,
            COALESCE(doThis.deeraw, -1) As deeraw  , COALESCE(doThat.HeroSheema, -1) As HeroSheema,
            Jootey.deeraw * Jootey.HeroSheema As BigBang
      From someTable....
      WHERE blahblah NOT NULL AND blahblah2 LIKE "abc"
     ) t
WHERE IsUserFruitEater > 0 or IsUserOnSite > 0;

我不确定min() 的用途。您没有group by，这是使用having 子句的问题。
