Question

我使用下面的代码在出现某个字符或数字后，在分隔的字符串中提取一些数据，我希望在拉出这些值之前拉出另一条数据。我不完全理解代码是如何工作的，尽管我确实理解它的元素。我只想重复拉动并将其集成到查询结果中。

USE RUG_Data 

IF OBJECT_ID('tempdb..#splitoutdata','U') IS NOT NULL DROP TABLE #SPLITOUTDATA;
CREATE TABLE #SPLITOUTDATA (
    INDEX1 INT,
    ROWNUM INT,
    BITOFDATA VARCHAR(max));


IF OBJECT_ID(N'dbo.Split_XML', N'TF') IS NOT NULL DROP FUNCTION dbo.Split_XML
GO
SET QUOTED_IDENTIFIER ON

CREATE FUNCTION dbo.Split_XML
    (
     @Parameter VARCHAR(MAX)
    ,@Delimiter VARCHAR(1)
    )
RETURNS @Result TABLE
    (
     ItemNumber INT
    ,ItemValue VARCHAR(MAX)
    )
AS 
    BEGIN
        DECLARE @XML XML ;
        SET @Parameter = ( SELECT   @Parameter
                         FOR XML PATH('')
                         ) ;
        SELECT  @XML = '<r>' + REPLACE(@Parameter, @Delimiter, '</r><r>') + '</r>' ;

        INSERT  INTO @Result
                (
                 ItemNumber
                ,ItemValue
                )
                SELECT  ROW_NUMBER() OVER ( ORDER BY ( SELECT NULL) ) AS ItemNumber
                ,       Item.value('text()[1]', 'VARCHAR(MAX)') AS ItemValue
                FROM    @XML.nodes('//r') R ( Item ) ;
        RETURN ;
    END ;
GO


;WITH
REFORMATTEDDATA AS

    row_number()over(order by (select null)) as INDEX1,

SELECT

        --  AND 
        --(SELECT BITOFDATA FROM #SPLITOUTDATA so5 WHERE so5.DC_INDEX_FK = so1.DC_INDEX_FK AND so5.ROWNUM = 10) NOT IN ('TR01')

) AS PVT



IF OBJECT_ID('tempdb..#splitoutdata','U') IS NOT NULL DROP TABLE #SPLITOUTDATA;
IF OBJECT_ID(N'dbo.Split_XML', N'TF') IS NOT NULL DROP FUNCTION dbo.Split_XML

目前我的查询结果显示为 -

[Date], [MPAN],
[1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],
[20],[21],[22],[23],[24],[25],[26],[27],[28],[29],[30],[31],[32],[33],[34],[35],[36],[37],[38],[39],[40],[41],[42],[43],[44],[45],[46],[47],[48],[49],[50]

我希望

[Date], [MPAN],
[E/A],[1], [E/A], [2], [E/A], [3], [E/A], [4], [E/A], [5], [E/A], [6], [E/A], [7], [E/A], [8], [E/A], [9], [E/A], [10], [E/A], [11], [E/A], [12], [E/A], [13], [E/A], [14], [E/A], [15], [E/A], [16], [E/A], [17], [E/A], [18], [E/A], [19], [E/A],[20], [E/A], [21], [E/A], [22], [E/A], [23], [E/A], [24], [E/A], [25], [E/A], [26], [E/A], [27], [E/A],[28], [E/A], [29], [E/A], [30], [E/A], [31], [E/A], [32], [E/A], [33], [E/A], [34], [E/A],[35], [E/A],[36], [E/A], [37], [E/A], [38], [E/A], [39], [E/A], [40], [E/A], [41], [E/A], [42], [E/A], [43], [E/A], [44], [E/A], [45], [E/A], [46], [E/A], [47], [E/A], [48], [E/A],[49], [E/A], [50]

E / A值也在分隔的字符串中，并且在我每次拉动的值之前都有一个部分，所以我假设我会用某些代码将它拉出来：

(SELECT BITOFDATA FROM #SPLITOUTDATA so4 WHERE so4.INDEX1 = so1.INDEX1 AND so4.ROWNUM = so1.ROWNUM +2) AS BITOFDATA 
FROM #SPLITOUTDATA so1 
WHERE BITOFDATA = '012'

由于某些原因我无法让它工作，因为我对此很新，但我认为它相当简单。

很抱歉，如果我没有很好地解释它。

Answer 1

没有样本数据很难判断，但你应该能够第二次在你的PIVOT结果上进行PIVOT以获得你想要的结果

从分隔字符串中提取另一位数据以获取查询结果
