Hi Daniel,
Thanks for your input.I have tried using foreach initially but the problem persists.
I am pasting my input xml and xslt mapping below
input xml:
<?xml version="1.0" encoding="windows-1252" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"

<xsd:element name="data">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="element1" type="dataCollection"/>
<xsd:element name="element2" type="dataCollection"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="dataCollection">
<xsd:sequence>
<xsd:element name="seqid" type="xsd:string"/>
<xsd:element name="value" type="xsd:string"/>
<xsd:element name="description" type="xsd:string"/>
<xsd:element name="price" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
xslt mapping
<?xml version="1.0" encoding="UTF-8" ?>
<?oracle-xsl-mapper

</xsl:for-each>
</ns1:Testatble1Collection>
</xsl:template>
</xsl:stylesheet>
the same problem persists.
I tested the same input and xslt mapping for a table which does not have auto-increment primary key through trigger,it works perfectly fine.
but the same fails when i have a table with auto-increment primary key named 'id' which is inserted as per below sql:
CREATE TRIGGER TESTTABLE1_TRIG
BEFORE INSERT ON TESTATBLE1
FOR EACH ROW
BEGIN
SELECT test_seq.NEXTVAL
INTO :new.id
FROM dual;
END;
is it a really a limitation with soa db adapter or i am doing it wrong.
Regards...
