SQL XQuery-将整数SQL变量值插入xml变量

我得到了这个问题：

DECLARE @UserId INT
DECLARE @StateChangeInformation XML

SET @UserId = 1
SET @StateChangeInformation = '<stateChangeInformation EnableOverrideMarking="1"></stateChangeInformation>'
SET @command = 'DECLARE @UserIdXml XML; SET @UserIdXml = ''<userID>{ sql:variable("@UserId") }</userID>''; SET @StateChangeInformation.modify(''insert sql:variable("@UserIdXml") into (/stateChangeInformation)[1]'')'

EXEC sp_executesql @stmt = @command,
                   @params = N'@StateChangeInformation xml out',
                   @StateChangeInformation= @StateChangeInformation OUTPUT

SELECT @StateChangeInformation

DECLARE@UserId INT
声明@statechangeinformationxml
设置@UserId=1
设置@StateChangeInformation=“”
SET@command='DECLARE@UserIdXml；SET@UserIdXml='{sql:variable（@UserId”）}'；设置@StateChangeInformation.modify（“'insert sql:variable（@UserIdXml”）到（/StateChangeInformation）[1]”）
EXEC sp_executesql@stmt=@命令，
@params=N'@StateChangeInformation xml out'，
@StateChangeInformation=@StateChangeInformation输出
选择@StateChangeInformation

我要做的是将XML输出为：

<stateChangeInformation>
  <userID>1</userID>
</stateChangeInformation>

1.

目前，我得到以下输出：

<stateChangeInformation EnableOverrideMarking="1">
  <userID>"{ sql:variable("@UserId") }"</userID>
</stateChangeInformation>

“{sql:variable（@UserId”）}”

请帮忙

您需要将

@UserId

作为参数发送到动态SQL，并使用连接来获取XML中的值

DECLARE @command nvarchar(max)
DECLARE @UserId INT
DECLARE @StateChangeInformation XML

SET @UserId = 1
SET @StateChangeInformation = '<stateChangeInformation EnableOverrideMarking="1"></stateChangeInformation>'
SET @command = 'DECLARE @UserIdXml XML; 
                SET @UserIdXml = ''<userID>''+cast(@UserId as varchar(10))+''</userID>''; 
                SET @StateChangeInformation.modify(''insert sql:variable("@UserIdXml") into (/stateChangeInformation)[1]'')'

EXEC sp_executesql @stmt = @command,
                   @params = N'@StateChangeInformation xml out, @UserId int',
                   @StateChangeInformation= @StateChangeInformation OUTPUT, @UserId = @UserId

SELECT @StateChangeInformation

DECLARE@command-nvarchar（最大值）
声明@UserId INT
声明@statechangeinformationxml
设置@UserId=1
设置@StateChangeInformation=“”
SET@command='DECLARE@UserIdXml；
将@UserIdXml=''''设置为+cast（@UserId为varchar（10））+''；
设置@StateChangeInformation.modify（“'insert sql:variable（@UserIdXml”）到（/StateChangeInformation）[1]”）
EXEC sp_executesql@stmt=@命令，
@params=N'@StateChangeInformation xml out，@UserId int'，
@StateChangeInformation=@StateChangeInformation输出，@UserId=@UserId
选择@StateChangeInformation

是的，我已经知道了。我完全按照你说的做了，所以我会记下你的答案：谢谢！
