如何从XML中获取数据并更新数据库表

Question

我将序列化集合（XML）传递给存储过程。我的XML结构是 -

<ArrayofDepartmentEntity> 
    <Department> 
    <id>1004</id> 
    <budget>2500.oo</budget> 
    </Department> 
    <Department> 
    <id>1080</id> 
    <budget>3500.oo</budget> 
    </Department> 
    <Department> 
    <id>1029</id> 
    <budget>4500.00</budget> 
    </Department> 
</ArrayofDepartmentEntity> 

如何更新相应的地方部门ID是在上面的XML预算列？可以任何人写下sql语法。

我的SP syntax-

ALTER PROCEDURE [dbo].[usp_SaveDepartentBudget] (     
@departmentBudgetXML ntext = NULL     
)       
AS       
BEGIN 
DECLARE @ptrHandle int  
EXEC sp_xml_preparedocument @ptrHandle OUTPUT, @departmentBudgetXML 
....Here I want to update Budget foreach departmentID in @departmentBudgetXML

试试这个代码。

DECLARE @XMLString XML 
SET @XMLString = '<ArrayofDepartmentEntity> 
    <Department> 
    <id>1004</id> 
    <budget>2500.oo</budget> 
    </Department> 
    <Department> 
    <id>1080</id> 
    <budget>3500.oo</budget> 
    </Department> 
    <Department> 
    <id>1029</id> 
    <budget>4500.00</budget> 
    </Department> 
</ArrayofDepartmentEntity>' 
SELECT 
Department.col.value('id[1]','VARCHAR(20)')AS Id, 
Department.col.value('budget[1]','VARCHAR(20)')AS Budget 
FROM @XMLString.nodes('//Department') Department(col) 

编辑：这里是代码更新

UPDATE tblInfo SET Budget = Department.col.value('budget[1]','MONEY') 
FROM @XMLString.nodes('//Department') Department(col) 
WHERE tblInfo.Id = Department.col.value('id[1]','INT')
