使用 SSIS 将 XML 数据加载到表中

Question

I have a XML like below

<MYLIST>
        <Frame Id="89900981" Name="Gxown" Qty="0.0">
          <Frame Id="354653-01" Name="Frametop" Qty="1.0" />
          <Frame Id="656997-23" Name="FrameNM" Qty="1.0" />
          <Frame Id="776879921" Name="PINOBK" Qty="2.0" />
        </Frame>
</MYLIST>

Now I want to load the data into table like below

+----------+-----------+----------+-----+
| HEAD     | SUBS      | NAME     | QTY |
+----------+-----------+----------+-----+
| 89900981 | 354653-01 | Frametop | 1.0 |
+----------+-----------+----------+-----+
| 89900981 | 656997-23 | FrameNM  | 1.0 |
+----------+-----------+----------+-----+
| 89900981 | 776879921 | PINOBK   | 2.0 |
+----------+-----------+----------+-----+           

Basically under the MYLIST node, the first node Frame is the Head of all. So I want to put that as in HEAD column (same for all rows under it) and other in SUBS column. Is this possible? I have tried using the output MYLIST_Frame_Frame . With this i'm able to load the SUBS , NAME and QTY column but the HEAD is available in MYLIST_Frame . I'm not sure how to combine this. I have tried using MERGE but that is inserting HEAD as a separate row.

Answer 1

you can use this code in your package: The core part of the answer is about using openxml function. It has three parameter in which the second one is in xpath format.

declare @Xml nvarchar(4000) = '
<MYLIST>
    <Frame Id="89900981" Name="Gxown" Qty="0.0">
      <Frame Id="354653-01" Name="Frametop" Qty="1.0" />
      <Frame Id="656997-23" Name="FrameNM" Qty="1.0" />
      <Frame Id="776879921" Name="PINOBK" Qty="2.0" />
    </Frame>

'

declare @idoc INT
EXEC sp_xml_preparedocument @idoc OUTPUT, @Xml;
select
    (select
        Id as Head
     from openxml(@idoc, '/MYLIST/Frame', 1) 
     with (Id nvarchar(32))) as Head,
    Id as SUBS,
    [Name],
    Qty
from openxml(@idoc, '/MYLIST/Frame/Frame[position()<=3]', 1)
with 
    (Id nvarchar(32),
     [Name] nvarchar(32),
     [Qty] decimal(2,1))
