Using for-each for input into a database adapter

Question

As input to a Web service I have an XSD that has parent elements and two unbounded child elements. I want to use XSLT to loop through the child elements to include them as comma separated strings for use in an IN clause in the query of the database adapter. I have the following XSLT in the input to database adapter XSL:
<db:child_elements>
  <xsl:attribute name="xsi:nil">
    <xsl:value-of select="/inp1:path/inp1:to/inp1:child_elements/@xsi:nil"/>
  </xsl:attribute>
  <xsl:for-each select="/inp1:path/inp1:to/inp1:child_elements/inpl:child_elements">
    <xsl:value-of select="."/>
    <xsl:if test="position() != last()">
      <xsl:text>,</xsl:text>
    </xsl:if>
  </xsl:for-each>
</db:child_elements>I am getting three error:
1) Error: Invalid Usage of <for-each> Element
2) Error: Invalid Usage of <if> Element
3) Error: This node is already mapped, repeating nodes not supported : "/db:databaseAdapterInput/db:child_elements"
Any idea of what the problem is here? Are for-each loops and if statements simply not allowed in Oracle SOA Suite? Thanks in advance!

For SQL Server 2005+ you can use the OUTPUT clause. E.g.
DECLARE @Source TABLE ( ID INT, Payload INT );
DECLARE @Destination TABLE
ID INT IDENTITY ,
Payload INT
DECLARE @IdentityValues TABLE ( ID INT );
INSERT INTO @Source
VALUES ( 1, 1 ),
( 2, 2 ),
( 3, 3 );
INSERT INTO @Destination
( Payload )
VALUES ( 0 );
INSERT INTO @Destination
( Payload )
OUTPUT INSERTED.ID
INTO @IdentityValues
SELECT S.Payload
FROM @Source S;
SELECT D.ID ,
D.Payload
FROM @Destination D;
SELECT IV.ID
FROM @IdentityValues IV;
