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>

如何更新相应的预算列，其中部门ID在上面的XML中？可以任何正文记下sql语法。

我的SP语法 -

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

试试这段代码。

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：以下是更新的代码

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')
