獲取分組數據使用XQuery - SQL服務器2008

Question

這裏是我的XML看起來像：

<Company xmlns ="http://abc.com/rules"> 
<Employee id="E1" number="0000007535"> 
    <Payment disposition="Open" type="ABC" amount_paid="100.00" /> 
    <Payment disposition="Closed" type="XYZ" amount_paid="468.00" /> 
    <Payment disposition="Open" type="AOD" amount_paid="156.00" /> 
    <Payment disposition="Closed" type="ONB" amount_paid="2834.00" /> 
</ Employee > 
<Employee id="E1" number="0000007536"> 
    <Payment disposition="Open" type="DFG" amount_paid="200.00" /> 
    <Payment disposition="Closed" type="HFK" amount_paid="568.00" /> 
</ Employee > 
<Employee id="E1" number="0000007537"> 
    <Payment disposition="Open" type="TTT" amount_paid="600.00" /> 
    <Payment disposition="Closed" type="BBB" amount_paid="368.00" /> 
</ Employee > 
<Employee id="E2" number="0000007541"> 
    <Payment disposition="Open" type="EEE" amount_paid="0.00" /> 
    <Payment disposition="Closed" type="WWW" amount_paid="568.00" /> 
    <Payment disposition="Closed" type="GHW" amount_paid="968.00" /> 
</ Employee > 
<Employee id="E2" number="0000007542"> 
    <Payment disposition="Open" type="QQQ" amount_paid="140.00" /> 
    <Payment disposition="Closed" type="CCC" amount_paid="68.00" /> 
</ Employee > 
<Employee id="E3" number="0000007551"> 
    <Payment disposition="Open" type="AAA" amount_paid="300.00" /> 
    <Payment disposition="Closed" type="TTT" amount_paid="668.00" /> 
</ Employee > 
</ Company> 

我需要得到所有的支付方式爲每個員工

一些事情，如：

E1 0000007535公開賽ABC 100.00

E1 0000007536關閉XYZ 468.00

......

E2 0000007541打開EEE 0.00
....

但是，下面的代碼給我只能Dispositon，類型和AmountPaid我不能夠把它映射到每個員工。

;WITH XMLNAMESPACES (DEFAULT 'http://abc.com/rules') 
select Disposition,Type,AmountPaid from 
     EMPLOYEE 
    OUTER APPLY 
    ( 
    SELECT 
    tbl.col.value('(@disposition)[1]','varchar(20)') AS Disposition, 
    tbl.col.value('(@type)[1]','varchar(20)') AS Type, 
    tbl.col.value('(@amount_paid)[1]','varchar(20)') AS AmountPaid 

    FROM xmldocument.nodes('//Employee/Payment') AS tbl(col) 

)Z 
WHERE xmlid = 500

我真的不明白這個XML如何與XmlDocument的列在你的EMPLOYEE表。 xml是否在員工中的行之間進行拆分，或者一名員工是否在xml中有多個員工？無論如何，這是一種查詢您提供的XML的方法。也許你可以使用它並適應你的情況。

declare @xmldocument xml = ' 
<Company xmlns="http://abc.com/rules"> 
    <Employee id="E1" number="0000007535"> 
     <Payment disposition="Open" type="ABC" amount_paid="100.00"/> 
     <Payment disposition="Closed" type="XYZ" amount_paid="468.00"/> 
     <Payment disposition="Open" type="AOD" amount_paid="156.00"/> 
     <Payment disposition="Closed" type="ONB" amount_paid="2834.00"/> 
    </Employee> 
    <Employee id="E1" number="0000007536"> 
     <Payment disposition="Open" type="DFG" amount_paid="200.00"/> 
     <Payment disposition="Closed" type="HFK" amount_paid="568.00"/> 
    </Employee> 
    <Employee id="E1" number="0000007537"> 
     <Payment disposition="Open" type="TTT" amount_paid="600.00"/> 
     <Payment disposition="Closed" type="BBB" amount_paid="368.00"/> 
    </Employee> 
    <Employee id="E2" number="0000007541"> 
     <Payment disposition="Open" type="EEE" amount_paid="0.00"/> 
     <Payment disposition="Closed" type="WWW" amount_paid="568.00"/> 
     <Payment disposition="Closed" type="GHW" amount_paid="968.00"/> 
    </Employee> 
    <Employee id="E2" number="0000007542"> 
     <Payment disposition="Open" type="QQQ" amount_paid="140.00"/> 
     <Payment disposition="Closed" type="CCC" amount_paid="68.00"/> 
    </Employee> 
    <Employee id="E3" number="0000007551"> 
     <Payment disposition="Open" type="AAA" amount_paid="300.00"/> 
     <Payment disposition="Closed" type="TTT" amount_paid="668.00"/> 
    </Employee> 
</Company>' 

;with xmlnamespaces(default 'http://abc.com/rules') 
select 
    p.value('../@id', 'varchar(10)'), 
    p.value('../@number', 'varchar(10)'), 
    p.value('@disposition', 'varchar(10)'), 
    p.value('@type', 'varchar(10)'), 
    p.value('@amount_paid', 'varchar(10)') 
from @xmldocument.nodes('Company/Employee/Payment') n(p) 

結果

---------- ---------- ---------- ---------- ---------- 
E1   0000007535 Open  ABC  100.00 
E1   0000007535 Closed  XYZ  468.00
