Question

我正在尝试插入数据VIA XML格式。同样的XML格式定义如下＆amp;我想在SQL表中逐行插入字段。但是，没有地址插入SQL表中，只有客户信息插入虚拟表中。

<XML>
    <Customer>
    <NAME>YOGESH</NAME>
    <CONTACT>YOGESH SHARMA</CONTACT>
    <Mobile>123456789</Mobile>
    <Status>A</Status>
    <MALE>1</MALE>
    <Add>
       <ADD1>
             <Address>AHMEDABAD</Address>
             <State>GUJARAT</State>
             <City>AHMEDABAD</City>
             <Pincode>380016</Pincode>
      </ADD1>
      <ADD2>
             <Address>RAJKOT</Address>
             <State>GUJARAT</State>
             <City>RAJKOT</City>
             <Pincode>360001</Pincode>
     </ADD2>
    </Add>
    </Customer>
</XML>

我的SP如下：

ALTER PROCEDURE [dbo].[OPENXMLDUMMY]

 @xmlCustomer NTEXT

AS
 BEGIN
     DECLARE @DOC INT;
     EXEC sp_xml_preparedocument
          @DOC OUTPUT,
          @xmlCustomer;
     INSERT INTO Dummy
     (Name,
      Contact,
      Mobile,
      Status,
      Male,
      InsertDate
     )
            SELECT XML.NAME,
                   XML.Contact,
                   XML.Mobile,
                   XML.Status,
                   XML.Male,
                   GETDATE()
            FROM OPENXML(@DOC, '/XML/Customer', 2) WITH(Name VARCHAR(50), 
 Contact VARCHAR(75), Mobile BIGINT, Status VARCHAR(10), Male VARCHAR(10), 
 InsertDate DATETIME) XML;

    INSERT INTO DummyExtd
    (
      ID,
     Address,
     State,
     City,
     Pincode
    ) SELECT (SELECT ID FROM DUMMY WHERE Name = Name),
    XML.Address,
    XML.State,
    XML.City,
    XML.Pincode
    FROM OPENXML(@DOC, '/XML/Customer/Add',2) WITH (ID INT, Address 
    VARCHAR(50), State VARCHAR(50), City VARCHAR(50), Pincode INT) XML;

     EXEC sp_xml_removedocument @DOC;
 END;

所以，我只想在SQL表中插入以下格式的数据：

ID  Name    Contact         Mobile    Status    Male    InsertDate
1   YOGESH  YOGESH SHARMA   123456789   A         1  2017-07-26 13:28:30.957

ID  Address     State   City        Pincode
1   AHMEDABAD   GUJARAT AHMEDABAD   380016
1   RAJKOT      GUJARAT RAJKOT      360001

那么，我当前存储过程中的问题是什么？需要纠正它。

Answer 1

我在这里做了一个相同的演示。请仔细研究。

首先，我创建了两个表，即Customer（您的表名Dummy）和Customer_Address（您的表名DummyText）。它们看起来像下面的按扣。

表客户

表： Customer_Address

以下是您更新的商店程序。

ALTER PROCEDURE [dbo].[OPENXMLDUMMY]
 @xmlCustomer NTEXT
AS
 BEGIN
     DECLARE @DOC INT;
     Declare @CustId INT;
     EXEC sp_xml_preparedocument
          @DOC OUTPUT,
          @xmlCustomer;

     INSERT INTO Customer(Name, Contact, Mobile, Status, Male, InsertDate)
     SELECT XML.[NAME], XML.Contact, XML.Mobile, XML.Status, XML.Male, GETDATE() AS InsertDate
     FROM OPENXML(@DOC, '/XML/Customer', 2) WITH(NAME VARCHAR(50), CONTACT VARCHAR(75), Mobile BIGINT, Status VARCHAR(10), MALE VARCHAR(10), InsertDate DATETIME) XML;

     SET @CustId = SCOPE_IDENTITY()


    INSERT INTO Customer_Address(Cust_Id, Address, State, City, Pincode)
    SELECT @CustId AS Cust_Id, XML.Address, XML.State, XML.City, XML.Pincode
    FROM OPENXML(@DOC, '/XML/Customer/Add/ADD1',2) WITH 
    ( 
        Address VARCHAR(50), 
        State VARCHAR(50), 
        City VARCHAR(50),
        Pincode INT
    ) XML;

    INSERT INTO Customer_Address(Cust_Id, Address, State, City, Pincode)
    SELECT @CustId AS Cust_Id, XML.Address, XML.State, XML.City, XML.Pincode
    FROM OPENXML(@DOC, '/XML/Customer/Add/ADD2',2) WITH 
    ( 
        Address VARCHAR(50), 
        State VARCHAR(50), 
        City VARCHAR(50),
        Pincode INT
    ) XML;

    EXEC sp_xml_removedocument @DOC;

END

使用此过程，我执行了您的示例xml数据，它看起来就像下面两个表中的条目一样。

您的问题在

(SELECT ID FROM DUMMY WHERE Name = Name)

它返回DUMMY表中的所有值，并导致错误。

子查询返回的值超过1。这是不允许的子查询跟随=，！=，＆lt;，＆lt; =，＆gt;，＆gt; =或当子查询用作表达。

解决方案：

-- After the first insert

Declare @DummyId int = scope_identity() -- get new inserted id from dummy

INSERT INTO DummyExtd
(
  ID,
 Address,
 State,
 City,
 Pincode
) SELECT 
@DummyId,    
XML.Address,
XML.State,
XML.City,
XML.Pincode
FROM OPENXML(@DOC, '/XML/Customer/Add',2) WITH 
( -- ID INT, --- Remove it, ID tag doesn't exist in your xml
    Address VARCHAR(50), 
    State VARCHAR(50), 
    City VARCHAR(50), 
    Pincode INT
) XML;

通过MS SQL中的openxml存储过程在表中逐行插入数据
