Question

我有一个巨大的XML，有超过150个元素和属性。我需要使用来自SQL Server 2008表的数据填充少数（5或6）元素。这个创建的xml需要传递给webservice（到ESB），这必须按照每日计划进行。

我认为，在此处使用XML Path来创建XML并使用SSIS是没有意义的。任何人都可以建议一种方法吗？

这是示例XML。我只需要填写名称，地址和一些ID

Answer 1

一种方法是获取XML文档的空版本并将其分配给NVARCHAR（MAX）变量。对于要填充的每个节点或参数，请放置“标记”并使用替换函数填充该值。例如：

DECLARE @xml NVARCHAR(MAX)

SET @xml = N'<Company name="~company_name~">
<Department name="~dept_name~">
<Employee name="~employee_name~" title="~employee_title~" />
</Department>
</Company>'

SET @xml = REPLACE(@xml,N'~company_name~','Microsoft')
SET @xml = REPLACE(@xml,N'~dept_name~','Executive')
SET @xml = REPLACE(@xml,N'~employee_name~','Satya Nadella')
SET @xml = REPLACE(@xml,N'~employee_title~','CEO')

SELECT CAST(@xml AS XML)

这是一种更传统的方法。您需要在要更新的单元格中使用任意值：

DECLARE @example_data TABLE 
(FirstName VARCHAR(255) NOT NULL,
LastName VARCHAR(255) NOT NULL,
Gender CHAR(1) NOT NULL,
City VARCHAR(255) NOT NULL,
[State] CHAR(2) NOT NULL)

INSERT INTO @example_data
        ( FirstName , LastName , Gender , City , [State])
VALUES  ( 'Satya' , -- FirstName - varchar(255)
          'Nadella' , -- LastName - varchar(255)
          'M' , -- Gender - char(1)
          'Redmond' , -- City - varchar(255)
          'WA'  -- State - char(2)
        )
INSERT INTO @example_data
        ( FirstName , LastName , Gender , City , [State])
VALUES  ( 'Larry' , -- FirstName - varchar(255)
          'Ellison' , -- LastName - varchar(255)
          'M' , -- Gender - char(1)
          'Woodside' , -- City - varchar(255)
          'CA'  -- State - char(2)
        )


DECLARE 
@customer_xml XML,
@xml XML,
@temp NVARCHAR(255),
@FirstName VARCHAR(255),
@LastName  VARCHAR(255),
@Gender CHAR(1),
@City VARCHAR(255),
@State CHAR(2)

DECLARE xml_cursor CURSOR FOR

OPEN xml_cursor 

FETCH NEXT FROM xml_cursor into @FirstName, @LastName, @Gender, @City, @State

WHILE @@fetch_status = 0
BEGIN
    SET @xml = @customer_xml

    SET @xml.modify('
    replace value of (/Customer/CustomerData/FirstName[1]/text())[1]
    with sql:variable("@FirstName")

    SET @xml.modify('

    select @xml

    FETCH NEXT FROM xml_cursor into @FirstName, @LastName, @Gender, @City, @State
END

此方法不需要更新节点中的值。它只是插入一个新节点，然后删除旧节点：

DECLARE @example_data TABLE 
(FirstName VARCHAR(255) NOT NULL,
LastName VARCHAR(255) NOT NULL,
Gender CHAR(1) NOT NULL,
City VARCHAR(255) NOT NULL,
[State] CHAR(2) NOT NULL)

INSERT INTO @example_data
        ( FirstName , LastName , Gender , City , [State])
VALUES  ( 'Satya' , -- FirstName - varchar(255)
          'Nadella' , -- LastName - varchar(255)
          'M' , -- Gender - char(1)
          'Redmond' , -- City - varchar(255)
          'WA'  -- State - char(2)
        )
INSERT INTO @example_data
        ( FirstName , LastName , Gender , City , [State])
VALUES  ( 'Larry' , -- FirstName - varchar(255)
          'Ellison' , -- LastName - varchar(255)
          'M' , -- Gender - char(1)
          'Woodside' , -- City - varchar(255)
          'CA'  -- State - char(2)
        )


DECLARE 
@customer_xml XML,

@FirstName VARCHAR(255),

Answer 2

您还可以使用FLWOR，它允许您通过使用模板一次生成xml，并仅将数据添加到您想要的元素。您不需要创建表或存储过程。例如：

declare @x xml
set @x=(select FirstName, LastName from kc_consumer for xml path('CustomerData'))

SELECT @x.query('
for $a in /CustomerData
  return 
<CustomerData>
<StoreID></StoreID>

<FirstName>{data($a/FirstName)}</FirstName>
<LastName>{data($a/LastName)}</LastName>

<Gender></Gender>
<BirthMonth></BirthMonth>
<BirthYear></BirthYear>
<BirthDay></BirthDay>
<IsEmployee></IsEmployee>
<customerID></customerID>
</CustomerData>
')

我只是包含一些节点以便于阅读，你只需要粘贴剩下的节点。
