如何從XML中獲取數據並更新數據庫表

Question

我將序列化集合（XML）傳遞給存儲過程。我的XML結構是 -

<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> 

如何更新相應的地方部門ID是在上面的XML預算列？可以任何人寫下sql語法。

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 

Answer 1

試試這個代碼。

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) 

編輯：這裏是代碼更新

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')
