Query for FormSubmit data by ID via the SOAP API

Question

When I submit a form entry via the SOAP API request 'Create' it get an ID as well as the Form Type data in return:
<CreateResponse xmlns="https://secure.eloqua.com/API/1.2">
  <CreateResult xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
       <CreateResult>
            <EntityType>
                 <ID>21</ID>
                 <Name>aherghaewForm</Name>
                 <Type>Form</Type>
            </EntityType>
            <Errors/>
            <ID>3</ID>
       </CreateResult>
  </CreateResult>
</CreateResponse>
However, I can't seem to query for that ID. When using the request 'Query'
<ns:Query>
  <ns:eloquaType>
       <ns:ID>21</ns:ID>
       <ns:Type>Form</ns:Type>
  </ns:eloquaType>
  <ns:searchQuery>ID='3'</ns:searchQuery>
  <ns:pageNumber>1</ns:pageNumber>
  <ns:pageSize>20</ns:pageSize>
</ns:Query>
I receive the following Error:
The search query you provided is invalid: 'id' is invalid.
As the field 'ID' is not part of the FieldValueCollection, this outcome is not unexpected, but unfortunate, as it would greatly simplify querying for data that was just submitted. Querying for a field that is part of the FieldValueCollection delivers correct results.
Is there a way to do just that, or do i have to follow another approach to retrieve FormSubmit data?
Thanks,

OK. I see column X logic now:
SQL> select  id,
  2          name,
  3          case when instr(sys_connect_by_path(id,',') || ',',',4,') > 0 then 'X' else 'Y' end x
  4    from  worker
  5    start with id in (
  6                      select  id
  7                        from  worker
  8                        where boss_id is null
  9                        start with id = 4
10                        connect by prior boss_id = id
11                      )
12    connect by prior id = boss_id
13  /
        ID NAME                             X
         1 Mennan                           Y
         2 Ahmet                            Y
         3 Akin                             Y
         4 Ayse                             X
         5 Aylin                            X
         6 Selim                            Y
6 rows selected.
