Question

我有一个动态数据透视查询，在条件语句中使用csv值。我创建了一个函数（splitstring（“ABC，sd”，“，”）），它拆分csv字符串并以表格形式返回，函数正在'IN'条款条件下工作，除了在'PIVOT'声明中......

insert into @filteredUsers  select * from @users users
 Where (
    (@IncludeInactiveUsers = 1 AND ( users.Status = 'Active' OR (users.Status = 'Inactive')) )
 OR (@IncludeInactiveUsers = 0 AND  users.Status = 'Active')
)


SELECT @columns = STUFF((
            SELECT DISTINCT ',' + QUOTENAME(NAME)
            FROM @filteredUsers
            FOR XML PATH('')
                ,TYPE
            ).value('.', 'NVARCHAR(MAX)'), 1, 1, '');

SELECT @SelectedColumns = STUFF((
            SELECT DISTINCT ',ISNULL(' + QUOTENAME(NAME) + ', ''N'') AS [' + NAME + ']'
            FROM @filteredUsers
            FOR XML PATH('')
                ,TYPE
            ).value('.', 'NVARCHAR(MAX)'), 1, 1, '');



DECLARE @loanProgramChannels TABLE (
    id UNIQUEIDENTIFIER
    ,NAME VARCHAR(500)
    ,[Broker] VARCHAR(2)
    ,[Correspond] VARCHAR(2)
    ,[Retail] VARCHAR(2)
    );
insert into @loanProgramChannels  select
        id,
        [Loan Program Name],
        ISNULL([Broker],'N') as [Broker],
        ISNULL([Correspond],'N') as [Correspond],
        ISNULL([Retail],'N') as [Retail]
    FROM
        (
            SELECT LoanPrograms.Id
            , LoanPrograms.NAME AS [Loan Program Name]
            , ' Y ' AS Y
            , Channels.NAME AS [ChannelType]
            FROM LoanPrograms
            LEFT JOIN LoanProgramChannels ON LoanPrograms.id = LoanProgramChannels.Loanprogram_Id
            LEFT JOIN Channels ON Channels.id = LoanProgramChannels.Channel_id
        ) programs
        PIVOT
        (
            MAX(Y) FOR [ChannelType] IN ([Broker],[Correspond],[Retail])
        )PivotTable

SELECT Name,Broker,Correspond,Retail,  @SelectedColumns 
FROM
(
    SELECT LoanPrograms.NAME
    ,LP.[Broker]
    ,LP.[Correspond]
    ,LP.[Retail]
    ,(
        CASE 
            WHEN UserParameterValues.value IS NULL
                THEN ' N '
            ELSE ' Y '
            END
        ) AS value
    ,(users.FirstName + space(1) + users.LastName) FullName
    FROM LoanPrograms
    LEFT JOIN UserParameterValues ON LoanPrograms.id = UserParameterValues.ValueId
    LEFT JOIN Parameters on UserParameterValues.ParameterId = Parameters.id 
        AND Parameters.Name = 'UwHierarchy'
    LEFT JOIN users ON UserParameterValues.UserId = Users.Id
    LEFT JOIN @loanProgramChannels LP ON LP.id = loanPrograms.id


) AS UsersTable
PIVOT 
(
SUM(value)
  FOR FullName IN( SELECT *
                FROM dbo.SplitString(@UserNames, ',' ) ) AS pvt

不确定如何在我的PIVOT语句IN子句中使用相同的函数。？

Answer 1

IN子句中的Pivot子句与IN子句中的Where运算符不同。
它指定了pivot的列，SQL Server需要一个常量的列列表，而不是表为了使此数据透视查询正常工作，您必须使用动态sql。

我打算尝试重新编写你的代码，但是我不太确定你需要在数据透视表中使用哪些列，所以我只是给你这个解释动态数据透视技术的link在sql server中。
