Question

我正在尝试将XML文件导入SQL Server数据库。请查看代码和xml文件。提前致谢。

我试图google很多页面但是所有这些页面只涉及一个孩子（或者如何调用它）。

但在我的真实xml中，结构就像

:1x supplier --> multiple orders --> multiple customers --> multiple products.

我们需要创建一个存储过程，当我们获取XML文件时将调用该存储过程。

再次感谢Petr

SQL代码：

DROP TABLE #TEST

CREATE TABLE #TEST
(CUSTID VARCHAR(10),CUSTNAME VARCHAR(50),PRODUCT VARCHAR(500))

INSERT INTO #TEST(CUSTID,CUSTNAME,PRODUCT)
SELECT
    x.orders.query('order/customer/cust_id').value('.', 'VARCHAR(10)'),
    x.orders.query('order/customer/name').value('.', 'VARCHAR(50)'),
    x.orders.query('order/product_lines/product/supplier_prod_num').
   value('.','VARCHAR(500)') 
FROM
   (SELECT CAST(x AS XML)
    FROM OPENROWSET(
          BULK '\\test\Test.xml',
          SINGLE_BLOB) AS T(x)) AS T(x) 
    CROSS APPLY
        x.nodes('order_batch/orders/order/product_lines/product') AS x(orders)

select * from #test

要测试的XML文件：

<order_batch>
  <order_header>
    <doc_format_ver>1.0</doc_format_ver>
    <originating_software>
      <software_name>test</software_name>
      <software_ver>2.0</software_ver>
    </originating_software>
  </order_header>
  <supplier>
    <cp_supplier_id>93</cp_supplier_id>
    <name>supname</name>
    <address_line_1>address_line_1</address_line_1>

      <product_lines>
        <product p_count="1">
          <supplier_prod_num>15115</supplier_prod_num>

        </product>
        <product p_count="2">

        </product>
      </product_lines>
    </order>
    <order o_count="2">

这个怎么样：

CREATE TABLE #TEST (CUSTID VARCHAR(50), CUSTNAME VARCHAR(50), PRODUCT VARCHAR(500))

DECLARE @input XML 

SELECT @input = CAST(x AS XML)
FROM OPENROWSET
     (BULK '\\test\Test.xml',
      SINGLE_BLOB) AS T(X)

INSERT INTO #TEST(CUSTID, CUSTNAME, PRODUCT)
    SELECT
        Customers.value('(cust_id)[1]', 'VARCHAR(50)'),
        Customers.value('(name)[1]', 'VARCHAR(50)'),
        Products.value('(supplier_prod_num)[1]', 'VARCHAR(500)')
    FROM
        @input.nodes('/order_batch/orders/order') AS Tbl(Orders)
    CROSS APPLY
        Orders.nodes('customer') AS TblC(Customers)
    CROSS APPLY
        Orders.nodes('product_lines/product') AS TblP(Products)

这会“粉碎”XML并使用嵌套的CROSS APPLY .nodes()方法从订单节点中提取任意数量的客户，以及任意数量的产品。

XML文件导入到具有多个子项的SQL数据库
