T-SQL和XML输出

Question

所以我已经写了关于联接和左联接等的信息。 但是，我在使用XML部分时遇到了麻烦。 我可以将所有数据放入数据集中。 但是我无法以我想要的方式获取数据来输出xml。

左边的TransactionTable与transactionID上的TimeEntry表联接。 一对多的TransactionTable内部连接到ClientTable 1对1

在select语句的左侧和内部联接中，所有数据都能很好地输出。 所有数据都在那里。

但是，我需要它以所需的XML格式输出。 无法弄清楚该怎么做。 走近了，但是每次我走近时，我都会遇到另一个障碍。

见所附图片

更新：这里是我正在运行的示例查询

SELECT
            tt.TransactionID as transactionID,
            c.ClientID as customerRefID,
            c.ClientCompany as customerCompanyName,
            c.clientEmail as customerEmailAddress,
            tt.TransactionInvNum as invoiceNumber,
            tt.InvoiceDate as invoiceDate,
            DATEADD(d,30,tt.InvoiceDate) as dueDate,
            tt.TransactionInvBillAmt as totalAmount,
            tt.TransactionInvBillAmt as balance,
            'USD' as currencyCode,
            'Invoice from Customer X' as description,
            '30' as terms,
            right(tt.PRojectID, (LEN(tt.projectid) - charindex(':',tt.projectid))) as purchaseOrderNumber,
            right(tt.PRojectID, (LEN(tt.projectid) - charindex(':',tt.projectid))) as salesOrderNumber,

            INNER JOIN Client c
            ON c.ClientID = tt.ClientID
            LEFT JOIN timeentry te ON
            te.TransactionID = tt.transactionID
            WHERE tt.PayID is null 

        FOR XML PATH('receivableInvoice'), ROOT('receivableInvoices'), ELEMENTS

输出链接SQL的输出

Answer 1

您可以使用查询后将结果输出到xml使用

SELECT .... FROM TABLE1 INNER JOIN TABLE2 ...
FOR XML PATH('receivableInvoices')

也可以用于子元素，例如

SELECT .... 
 city AS "billTo/address/city" 
 .... 

我没有您的查询，所以我可以为您发布对帐单。

供属性使用

SELECT field_name AS "@refId"  ...

Answer 2

在这种情况下，直接连接效率不高，最好使用嵌套的FOR XML子查询：

SELECT
    tt.TransactionID as transactionID,
    c.ClientID as customerRefID, (
        select te.Id as [lineNumber],
            te.Description as [Description]
        from dbo.timeentry te
        where te.TransactionID = tt.transactionID
        for xml path('lineItem'), root('lineItems'), elements, type
    )
FROM dbo.TransactionTable tt 
    INNER JOIN dbo.Client c ON c.ClientID = tt.ClientID
WHERE tt.PayID is null 
FOR XML PATH('receivableInvoice'), ROOT('receivableInvoices'), ELEMENTS, type;

Answer 3

试试这个，您可能需要tweek的名称，或者我删除了带有时间条目的连接

    SELECTtime
tt.TransactionID as transactionID,
c.ClientID as customerRefID,
c.ClientCompany as customerCompanyName,
c.clientEmail as customerEmailAddress,
tt.TransactionInvNum as invoiceNumber,
tt.InvoiceDate as invoiceDate,
DATEADD(d,30,tt.InvoiceDate) as dueDate,
tt.TransactionInvBillAmt as totalAmount,
tt.TransactionInvBillAmt as balance,
'USD' as currencyCode,
'Invoice from Customer X' as description,
'30' as terms,
right(tt.PRojectID, (LEN(tt.projectid) - charindex(':',tt.projectid))) as purchaseOrderNumber,
right(tt.PRojectID, (LEN(tt.projectid) - charindex(':',tt.projectid))) as salesOrderNumber,
c.ClientCompany as "shipTo/address/line1",
c.ClientStreet as "shipTo/address/line2",
c.ClientStreet2 as "shipTo/address/line3",
c.ClientCity as "shipTo/address/city",
c.ClientState as "shipTo/address/stateProvince",
c.ClientZip as "shipTo/address/postalCode",
c.ClientFName + ' ' + c.ClientLName as "shipTo/contact/name",
c.ClientPhone as "shipTo/contact/phoneNumber",
c.ClientCompany as "billTo/address/line1",
c.ClientStreet as "billTo/address/line2",
c.ClientStreet2 as "billTo/address/line3",
c.ClientCity as "billTo/address/city",
c.ClientState as "billTo/address/stateProvince",
c.ClientZip as "billTo/address/postalCode",
cast(
  (  
    Select 
     te.lineNumber,
     te.hours,
     te.description
   From    timeentry te
 where te.TransactionID = tt.transactionID
 FOR XML PATH('lineItem'), ROOT('lineItems'), ELEMENTS ) as xml).query('.')

FROM TransactionTable tt 
INNER JOIN Client c
ON c.ClientID = tt.ClientID
WHERE tt.PayID is null 

FOR XML PATH('receivableInvoice'), ROOT('receivableInvoices'), ELEMENTS
