Question

我有一个查询，稍后将使用它来进行动态数据透视。我想在进行区分之前对这个查询进行排序。我怎样才能做到这一点？每当我下令订购时，它都会完全打破常规。

    DECLARE @cols NVARCHAR(max);
SET @cols = STUFF
(
    (SELECT distinct ',' + c.[PivotColumnTitle]
        FROM [myTable] c
        WHERE c.Id = @idInput
        AND c.IsPivotVisible = 1
              --order by c.PivotColumnOrder
        FOR XML PATH(''), TYPE
    ).value('.', 'NVARCHAR(MAX)') 
    ,1,1,''
)

Answer 1

尝试一下：

DECLARE @cols NVARCHAR(max);

SET @cols = STUFF
(
    (
        SELECT ',' + c.[PivotColumnTitle]
        FROM [myTable] c
        WHERE c.Id = @idInput
            AND c.IsPivotVisible = 1
        GROUP BY c.[PivotColumnTitle]
        order by MAX(c.PivotColumnOrder)
        FOR XML PATH(''), TYPE
    ).value('.', 'NVARCHAR(MAX)') 
    ,1,1,''
)

tsql排序方式与XML路径不同
