Message Mapping Nested Structure to key node in JDBC XML SQL Structure

Question

Hello everybody,
I'm facing the next problem, I have the following nested structure
<ns0:MT_Irdoc_ArchivoNested xmlns:ns0="http://ref.pemex.com/PI/FI/ArchivoIrdoc">
   <Header id_consecutivo="">
      <Transaction/>
      <Header2/>
      <Header3/>
      <Header4/>
      <Header5/>
      <Detail>
         <Transaction/>
         <Detail2/>
         <Detail3/>
         <Detail4/>
         <Detail5/>
      </Detail>
   </Header>
   <NombreArchivo/>
</ns0:MT_Irdoc_ArchivoNested>
as you can see, Detail is a nested Node from Header Node, and Detail is with occurrence 0...unbounded, I need to generate a SELECT XML SQL Structure as follows
   <StatementName>
          <dbTableName action=u201DSELECTu201D>
              <table>realDbTableName</table>
              <access>
                 <col1/>
                 <col2/>
                 <col3/>
              </access>
              <key1>
                 <col4>val4</col4>
                 <col5>val5</col5>
                 <col6>val6</col6>
              </key1>
          </dbTableName> 
   </StatementName>
now my problem is that col4 and col6 are values mapped from Header fields values, and col5 mus be mapped from Detail2 field of Detail Nested Structure, and Detail is 0...unbounded so it can contain any number of values and must included in the key structure, I tried by mapping the Detail Node to the key1 node, so it will generate n numbers of key1 nodes to include in the query, and the Detail number of nodes are not constant so I can't generate key2, key3, keyn...., so what I need is to create n numbers of instances of key1 node, but the problem is that when the mapping try to generate the second instance of key1 node it gives an error in the fields that comes from Header structure, maybe I'm trying to solve my problem wrong, could anyone give some advices or direction?, thanks in advance.

Answer 1

Julio,
After placing the below logic in the mapping editor
Details2 > SplitByValue> col5
Right click on the Details2 node and choose Context. By Default you will see Details, because Details2 is the child of Details node. I want you to choose the Parent of Details node, I believe that would be HeaderID, am I right?
If you don't want to do that then,
Details2 ---> Remove Context > SplitByvalue> col5 will do the trick!
