在 SQL Server 2014 中根据 XML 中的特定条件对多个节点值求和

Question

下面是 XML，我想计算“ClaimPayment.Amount”值的总和，其中“ClaimPayment.TypeCode”是赔偿金。意味着输出将是 10000。记住节点可以更多。

    <ZObject>   
      <Attribute Name="ClaimPayment">
        <ZObject>
          <Attribute Name="Re4eba255bf394bdbaccba77b6edca4f5">
            <ZObject>
              <Attribute Name="ClaimPayment.TypeCode">
                <ZObject>
                  <Value xsi:typeName="xs:string">Expense</Value>
                </ZObject>
              </Attribute>
              <Attribute Name="ClaimPayment.Amount">
                <ZObject>
                  <Value xsi:typeName="xs:decimal">3000.0000</Value>
                </ZObject>
              </Attribute>
            </ZObject>
          </Attribute>
          <Attribute Name="R0ffc51fa96594b7989a7dec13a4ddd15">
            <ZObject>
              <Attribute Name="ClaimPayment.TypeCode">
                <ZObject>
                  <Value xsi:typeName="xs:string">Indemnity</Value>
                </ZObject>
              </Attribute>
              <Attribute Name="ClaimPayment.Amount">
                <ZObject>
                  <Value xsi:typeName="xs:decimal">50000.0000</Value>
                </ZObject>
              </Attribute>
            </ZObject>
          </Attribute>
          <Attribute Name="R64b104f17aa94ffebb75ad0b2d8b2775">
            <ZObject>
              <Attribute Name="ClaimPayment.TypeCode">
                <ZObject>
                  <Value xsi:typeName="xs:string">Indemnity</Value>
                </ZObject>
              </Attribute>
              <Attribute Name="ClaimPayment.Amount">
                <ZObject>
                  <Value xsi:typeName="xs:decimal">50000.0000</Value>
                </ZObject>
              </Attribute>
            </ZObject>
          </Attribute>
        </ZObject>   
    </Attribute> 
</ZObject>

我已经用谷歌搜索了，到目前为止：

create table #claims(id int identity(1,1) , customdata xml)
;WITH XMLNAMESPACES (
Default 'http://www.oceanwide.com/ZObject/2014',
'http://www.w3.org/2001/XMLSchema' as xs,
'http://www.w3.org/2001/XMLSchema-instance' as xsi)
insert into #claims(customdata )
Select CAST(CustomData AS XML)
from Claims.Resources_Claim cB

;WITH XMLNAMESPACES (
Default 'http://www.oceanwide.com/ZObject/2014',
'http://www.w3.org/2001/XMLSchema' as xs,
'http://www.w3.org/2001/XMLSchema-instance' as xsi)
select x.y.query('(//ZObject/Attribute[@Name="ClaimPayment.TypeCode"]/ZObject/Value/text())')
, ISNULL(CAST(CAST(CustomData AS XML).query('sum(/ZObject/Attribute/ZObject/Attribute/ZObject/Attribute[@Name="ClaimPayment.Amount"]/ZObject/Value/text())') as nvarchar(max)),'') AS 'amount'
,cb.*from #claims cB
CROSS APPLY CB.CustomData.nodes('/ZObject/Attribute[@Name = "ClaimPayment"]') as x(y)
where CB.customdata.exist('(//ZObject/Attribute[@Name="ClaimPayment.TypeCode"]/ZObject/Value[.="Indemnity"])')=1

请尝试以下解决方案。

未提供最小的可重现示例。所以，我从臀部射击。

INSERT INTO @tbl (customdata) VALUES

输出

Answer 2

在这种情况下，您不需要将 XML 与 .nodes 分开，因为您可以纯粹在 XQuery

中对其求和

WITH XMLNAMESPACES 
(
    DEFAULT 'http://www.oceanwide.com/ZObject/2014',
    'http://www.w3.org/2001/XMLSchema' as xs,
    'http://www.w3.org/2001/XMLSchema-instance' as xsi
)
SELECT ID
    , Amount = customdata.value('sum(
      ZObject/Attribute/ZObject/Attribute/ZObject
      [
        Attribute[@Name = "ClaimPayment.TypeCode"]
        /ZObject/Value[text() = "Indemnity"]
      ]/Attribute[@Name = "ClaimPayment.Amount"]
      /ZObject/Value/text()
    )', 'decimal(18,9)')
FROM @tbl AS t;

ID	Amount
1	100000.000000000
