Example: XML Query With Order By Attributes

Previous Next

Here is an example of an XML query document with several Order By attributes specified:

<Query>

    <Table Name="PERSON">

        <Column Name="FAMILY_NAME" Condition="Jo%"

            Order-by-seqno="1"

            Order-by-direction="DESCENDING"/>

        <Column name="FIRST_NAME"

            Order-by-seqno ="2"/>

        <Column name="ADDRESS" Condition="%STREET%"/>

    </Table>

</Query>

 

This results in an XML output document that contains all columns of all records where FAMILY_NAME starts with 'Jo' and ADDRESS contains 'STREET':

<Persons>

    <PERSON ID="377" FAMILY_NAME="Jones" FIRST_NAME="Bill"

        ADDRESS="HIGHSTREET 501"/>

    <PERSON ID="377" FAMILY_NAME="Jones" FIRST_NAME="Patricia"

        ADDRESS="HIGHSTREET 501"/>

    <PERSON ID="312" FAMILY_NAME="Johnson" FIRST_NAME="Ann"

        ADDRESS="ELM STREET 105"/>

</Persons>

 

The records are sorted in descending order on FAMILY_NAME, and in ascending order on FIRST_NAME, which is only used for the ordering.

This is equivalent to:

INVOKE    XML.EXPORT

WITH

SELECT    *

FROM      person

WHERE     family_name   LIKE 'Jo%'

AND       address       LIKE '%STREET%'

ORDER BY  family_name   DESC

,         first_name    ASC
