在sql server存储过程中使用游标解析xml文档

我有一个xml文档，希望将其作为参数传递给存储过程 xml如下所示

<root> 
    <EMPLOYEE ID= 100> 
     <PERIOD>AUG-2010</PERIOD>
        <earnings> 
               <title>BASIC</title>
        <amount>2000</amount>
        <title>HRA</title>
        <amount>1000</amount>
        <title>CONVEYANCE</title>
        <amount>500</amount>
        </earnings> 
    </EMPLOYEE> 
     <EMPLOYEE ID= 101> 
    <PERIOD>AUG-2010</PERIOD>
          <earnings> 
               <title>BASIC</title>
        <amount>2000</amount>
        <title>HRA</title>
        <amount>400</amount>
        <title>CONVEYANCE</title>
        <amount>500</amount>
        </earnings> 
    </EMPLOYEE> 

 <EMPLOYEE ID= 102> 
    <PERIOD>AUG-2010</PERIOD>
          <earnings> 
               <title>BASIC</title>
        <amount>2000</amount>
        <title>HRA</title>
        <amount>800</amount>
        <title>CONVEYANCE</title>
        <amount>5000</amount>
        </earnings> 
 </EMPLOYEE> 
</root>

然后我转到外部循环，获取下一个员工id，并重复相同的操作

如何以openxml等任何方式访问内部子xml…

首先，这是无效的xml：

<EMPLOYEE ID= 102> 
    <PERIOD>AUG-2010</PERIOD>
          <earnings> 
               <title>BASIC</title>
        <amount>2000</amount>
        <title>HRA</title>
        <amount>800</amount>
        <title>CONVEYANCE</title>
        <amount>5000</amount>
        </earnings> 
 </EMPLOYEE> 

下一步：在

标记中有多个

..

标记对，但周围没有容器，这一事实使得解析几乎不可能（或非常混乱）

您将得到如下输出：

<earnings> 
   <earning>
     <title>BASIC</title>
     <amount>2000</amount>
   </earning>
   <earning>
     <title>HRA</title>
     <amount>800</amount>
   </earning>
   <earning>
     <title>CONVEYANCE</title>
     <amount>5000</amount>
   </earning>
</earnings> 

EmployeeID  Title         Amount
  100       BASIC          2000.0000
  100       HRA            1000.0000
  100       CONVEYANCE      500.0000
  101       BASIC          2000.0000
  101       HRA             400.0000
  101       CONVEYANCE      500.0000
  102       BASIC          2000.0000
  102       HRA             800.0000
  102       CONVEYANCE     5000.0000

<earnings> 
   <title>BASIC</title>
   <amount>2000</amount>
   <title>HRA</title>
   <amount>800</amount>
   <title>CONVEYANCE</title>
   <amount>5000</amount>
</earnings> 

<earnings> 
   <earning>
     <title>BASIC</title>
     <amount>2000</amount>
   </earning>
   <earning>
     <title>HRA</title>
     <amount>800</amount>
   </earning>
   <earning>
     <title>CONVEYANCE</title>
     <amount>5000</amount>
   </earning>
</earnings> 

SELECT
    RootData.Employee.value('(@ID)[1]', 'int') AS 'EmployeeID',
    E.E2.value('(title)[1]', 'varchar(50)') AS 'Title',
    E.E2.value('(amount)[1]', 'decimal(18,4)') AS 'Amount'
from
    (your XML column).nodes('/root/EMPLOYEE') AS RootData(Employee)
CROSS APPLY
    RootData.Employee.nodes('earnings/earning') AS E(E2)

EmployeeID  Title         Amount
  100       BASIC          2000.0000
  100       HRA            1000.0000
  100       CONVEYANCE      500.0000
