如何将数据插入两个累积表？

Question

我有 2 张桌子：tblProduct 和 tblTransaction。

请看下面的代码，这是我迄今为止尝试过的：-

 '<ArrayOfProduct>
          <Product>
            <GetSetParameter>
              <Parameter>
                <PClientID>2</PClientID>
                <PParameterID>1</PParameterID>
              </Parameter>
              <Parameter>
                <PClientID>2</PClientID>
                <PParameterID>2</PParameterID>
              </Parameter>
            </GetSetParameter>
            <PProductName>Yellow</PProductName>
            <PDescription>rtrtret</PDescription>
            <PClientID>2</PClientID>
            <PFromdate>2018/02/20</PFromdate>
            <PTodate>2018/02/20</PTodate>
          </Product>
          <Product>
            <GetSetParameter>
              <Parameter>
                <PClientID>2</PClientID>
                <PParameterID>1</PParameterID>
              </Parameter>
              <Parameter>
                <PClientID>2</PClientID>
                <PParameterID>2</PParameterID>
              </Parameter>
              <Parameter>
                <PClientID>2</PClientID>
                <PParameterID>3</PParameterID>
              </Parameter>
            </GetSetParameter>
            <PProductName>green</PProductName>
            <PDescription>rtrtret</PDescription>
            <PClientID>2</PClientID>
            <PFromdate>2018/02/20</PFromdate>
            <PTodate>2018/02/20</PTodate>
          </Product>
        </ArrayOfProduct>' 

这是我的数据。 我想将我的数据插入到 2 个表产品和参数中。第一个产品数据将插入，生成的 id 将插入参数表。

改变程序 xmlOrderInsert(

 @order nvarchar(max)
 )

  AS

DECLARE @index int, @OID int
EXEC sp_xml_preparedocument @index OUTPUT, @order

BEGIN TRANSACTION

insert into Tbl_ProductMaster    

 (ProductName, 

 ProductDescription,   

 ClientID ,   

 IsActive  ,

 Fromdate,      

 Todate    

 ) 
 select PProductName,PDescription,PClientID,'True' as PisActive ,PFromdate,PTodate       

 FROM  OPENXML (@index, '/ArrayOfProduct/Product',2)    WITH (  PProductName varchar(50),                          

 PDescription varchar(6),                          

 PClientID varchar(30),

 PFromdate datetime,  

 PTodate datetime    ) 
IF @@ERROR<>0 BEGIN ROLLBACK TRANSACTION RETURN -100 END

SET @OID = SCOPE_IDENTITY()
INSERT INTO [Tbl_ParameterTransact] ( ProdID,   ClientID,   ParameterID)

--(2,1,1,@OID)

SELECT  @OID AS ProductID,PClientID, PParameterID
 FROM OpenXml( @index, '/ArrayOfProduct/Product/GetSetParameter/Parameter',2)   WITH 

 ( PClientID int, PParameterID int ) 
  IF @@ERROR<>0 BEGIN ROLLBACK TRANSACTION RETURN -101 END

COMMIT TRANSACTION

EXEC sp_xml_removedocument @index SELECT @OID AS ProductID

但作用域标识只获取最后插入的数据。这就是我得到的。

这就是我想要的：-

我不完全确定您想要完成什么，但为了捕获身份，您需要执行某种循环

看看这个例子，让我知道这是否是你的目标

        DECLARE @XML XML =

                        <PParameterID>1</PParameterID>
                      </Parameter>

                        <PParameterID>2</PParameterID>
                      </Parameter>
