Question

我正在设置此存储过程，但出现此错误：

无法绑定多部分标识符

在选择的所有列上。

这是我的查询：

ALTER PROCEDURE [dbo].[Ps_GetEquipeProjet] 
    @PROJET_ID INT = NULL,
    @RoleID INT = NULL
AS
BEGIN
    DECLARE @requete VARCHAR(250)
    SET @requete = (SELECT CleRepartition FROM EQUIPE_PROJET  
                    WHERE Projet_Id = @PROJET_ID AND Role_Id = 3 
                      AND CleRepartition IS NOT NULL) 

    SELECT 
        EP.Equipe_Projet_Id AS PROJET_ID,
        U.USR_ID, U.USR_NOM, U.USR_PRENOM,
        U.USR_LOGIN,
        RE.Role_Eq_Libelle AS ROLE_NOM,
        EP.CleRepartition = CASE
                               WHEN @RoleID = 1 AND @requete IS NOT NULL AND @requete = 75 
                                  THEN 25 
                               WHEN @RoleID = 1 AND @requete IS NOT NULL AND @requete = 50 
                                  THEN 50 
                               WHEN @RoleID = 2 AND @requete IS NOT NULL 
                                  THEN 20
                               ELSE NULL      
                            END   
    FROM 
        [EQUIPE_PROJET] EP
    INNER JOIN 
        UTILISATEUR U ON  U.USR_ID = EP.[User_Id]
    INNER JOIN 
        Ref_Role_Eq RE ON RE.Role_Eq_Id = EP.[Role_Id] 
    WHERE 
        (@PROJET_ID IS NULL OR @PROJET_ID = EP.[Projet_Id]) 
        AND EP.Deletion_Date IS NULL
        AND (@RoleID IS NULL OR [Role_Id] = @RoleID)
END

就像我在评论中说的那样，在将带有UPDATE的数据集返回到表示层的同一语句中，您无法SELECT的列。您首先需要UPDATE的值CleRepartition，然后执行SELECT。我无法对此进行测试，但是大概是您需要的：

ALTER PROCEDURE [dbo].[Ps_GetEquipeProjet] @PROJET_ID int = NULL,
                                           @RoleID int = NULL
AS
BEGIN
    DECLARE @requete varchar(250);
    SET @requete = (SELECT CleRepartition
                    FROM EQUIPE_PROJET
                    WHERE Projet_Id = @PROJET_ID
                      AND Role_Id = 3
                      AND CleRepartition IS NOT NULL);

    UPDATE EP
    SET CleRepartition = CASE
                              WHEN @RoleID = 1
                               AND @requete IS NOT NULL
                               AND @requete = 75 THEN 25
                              WHEN @RoleID = 1
                               AND @requete IS NOT NULL
                               AND @requete = 50 THEN 50
                              WHEN @RoleID = 2
                               AND @requete IS NOT NULL THEN 20
                              ELSE NULL
                         END
    FROM [EQUIPE_PROJET] EP
         INNER JOIN UTILISATEUR U ON U.USR_ID = EP.[User_Id]
         INNER JOIN Ref_Role_Eq RE ON RE.Role_Eq_Id = EP.[Role_Id]
    WHERE (@PROJET_ID IS NULL
        OR @PROJET_ID = EP.[Projet_Id])
      AND EP.Deletion_Date IS NULL
      AND (@RoleID IS NULL
        OR [Role_Id] = @RoleID);


    SELECT EP.Equipe_Projet_Id AS PROJET_ID,
           U.USR_ID,
           U.USR_NOM,
           U.USR_PRENOM,
           U.USR_LOGIN,
           RE.Role_Eq_Libelle AS ROLE_NOM,
           EP.CleRepartition
    FROM [EQUIPE_PROJET] EP
         INNER JOIN UTILISATEUR U ON U.USR_ID = EP.[User_Id]
         INNER JOIN Ref_Role_Eq RE ON RE.Role_Eq_Id = EP.[Role_Id]
    WHERE (@PROJET_ID IS NULL
        OR @PROJET_ID = EP.[Projet_Id])
      AND EP.Deletion_Date IS NULL
      AND (@RoleID IS NULL
        OR [Role_Id] = @RoleID);
END;

换句话说，这里的内容称为“全部查询”，或者（如Aaron Bertrand所说的）是“厨房水槽”查询。确实，您想使用动态SQL进行此类查询，或者使用OPTION (RECOMPILE)（我个人喜欢前者）。这是一些有关盖尔·肖（Gail Shaw）和贝特朗（Bertrand）的主题的文章：Catch-All Queries，Revisiting Catch-All Queries和#BackToBasics: An Updated "Kitchen Sink" Example
