SQL 服務器：Row_Number() 按 xml 數據順序排序

Question

我正在提取 XML 數據。 我用它創建臨時表。 但我希望按照 xml 數據的順序進行排序。 我該怎么做？

程序：

ALTER PROCEDURE [dbo].[diziDonustur]
@date xml = null,
@islem xml = null
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @degisken int

    EXEC sp_xml_preparedocument @degisken OUTPUT, @date

    select 
    akt = ROW_NUMBER() OVER(ORDER BY cektar),
    cektar 
    into #tmp
    from cek 
    where cektar in (
      SELECT Convert(datetime,Convert(nvarchar,text)) FROM OPENXML (@degisken, '/ArrayOfDateTime/dateTime') where text is not null 
    )
    group by cektar

    
    
    exec sp_xml_removedocument @degisken;  



    EXEC sp_xml_preparedocument @degisken OUTPUT, @islem

    SELECT akt = ROW_NUMBER() OVER(ORDER BY Islem),Islem INTO #tmp4 from(
        SELECT Convert(decimal,Convert(nvarchar,text)) as Islem FROM OPENXML (@degisken, '/ArrayOfDecimal/decimal') where text is not null 
    )a--here I want to sort by xml data itself, not by operation


    
    select cektar,Islem into #tmpXmlBirlesim from #tmp inner join #tmp4 on #tmp.akt = #tmp4.akt
    select * from #tmpXmlBirlesim
END

運行一個程序：

exec diziDonustur @islem = '<?xml version="1.0"?>
<ArrayOfDecimal xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <decimal>4000000</decimal>
  <decimal>343</decimal>
  <decimal>4000000</decimal>
</ArrayOfDecimal>', @date = '<?xml version="1.0"?>
<ArrayOfDateTime xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <dateTime>2021-12-18T00:00:00</dateTime>
  <dateTime>2021-12-19T00:00:00</dateTime>
  <dateTime>2021-12-20T00:00:00</dateTime>
</ArrayOfDateTime>'

在 #tmp4 中分配 row_number() 時，我按 Islem 列進行排序。 但隨后它從最小的數字排序。 我想按 XML 的順序排序，而不是按 Transaction 列排序。

也就是說，無論 XML 數據以何種順序出現在我這里，它都應該按該順序放置在 #tmp4 表中。

例如：

'<?xml version="1.0"?>
<ArrayOfDecimal xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <decimal>4000000</decimal> --should be number 1 in this table
  <decimal>343</decimal> --should be number 2 in this table
  <decimal>4000000</decimal> --should be number 3 in this table
</ArrayOfDecimal>'

Answer 1

按照上一個答案

declare @islem xml = '<?xml version="1.0"?>
<ArrayOfDecimal xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <decimal>4000000</decimal>
  <decimal>343</decimal>
  <decimal>4000000</decimal>
</ArrayOfDecimal>';

with Numbers(Number) as(
-- quick inline tally
 select 1 union all 
 select 2 union all 
 select 3 
)
 
select T.X.value('text()[1]', 'nvarchar(100)') as RowLabel,
       N.Number as RowNumber
from Numbers as N
cross apply @islem.nodes('ArrayOfDecimal/decimal[sql:column("N.Number")]') as T(X)
where N.Number between 1 and @islem.value('count(ArrayOfDecimal/decimal)', 'int');

您可能希望在查詢中創建一個持久的Numbers計數表而不是快速示例。
