How can I tell XQuery to stop putting the namespace information on every node, instead somehow add reference to the name space.

<a:listOfParty xmlns:a="http://www.test.org/schema/AP/party"><a:party><a:id>4926</a:id><a:typeCode><b:value xmlns:b="http://www.test.org/schema/AP/core"/></a:typeCode><a:description/><a:relatedDates><b:dateData xmlns:b="http://www.test.org/schema/AP/core">

Thanks

Hi Rusty,

Which XQuery processor are you running?

Could you please show us the query?

Below is the query. When i run it it places the namespace data on every starting node, I wish a better way to just declare it once when it generates the XML and leave for e.g <a:id> as is. Trying to reduce XML size.

=======================================================================
declare namespace a = "http://www.test.org/schema/AP/party";
declare namespace b = "http://www.test.org/schema/AP/core";
declare function local:getParty($INPARTY as element(PARTY)) as element()*{

for $PARTY in collection("PARTY")/PARTY
where $PARTY/ID/text() = $INPARTY/ID/text()
return
<a:id>
{$PARTY/ID/text()}
</a:id>
union
<a:typeCode>
<b:value>
{$PARTY/TYPECODE/text()}
</b:value>
</a:typeCode>
};

let $SRCHPARTY := collection("PARTY")/PARTY[ID = 1234]
return
<a:listOfParty>
<a:party>
{local:getParty($SRCHPARTY)}
</a:party>
</a:listOfParty>

FYI... I am using DataDirect XQuery processor.

Thanks

Also, How can I call a XQuery function from java code that Stylus Studio generates?
The reason I ask becuase we would like to use the same query but would like different functions like for e.g

getPartyByFirstName()
getPartyByLastName()
getPartyByCountryCode() etc...

I can write all these functions in XQuery, but than how would I call it from java code (The one that StylusStudio generates).

Hi Rusty

To avoid name-space proliferation wrap your sequence with an element that carries the declarations

<root
xmlns:a="http://www.test.org/schema/AP/party"
xmlns:b="http://www.test.org/schema/AP/core"
>
{
let $SRCHPARTY := collection("PARTY")/PARTY[ID = 1234]
return
<a:listOfParty>
<a:party>
{local:getParty($SRCHPARTY)}
</a:party>
</a:listOfParty>
}
</root>

To invoke the query functions from java you should have one function per query. Make use of external variables to parametrize your query like that then use the XQJ API to call out from Java.

declare namespace a = "http://www.test.org/schema/AP/party";
declare namespace b = "http://www.test.org/schema/AP/core";
declare variable $partyID external;

declare function local:getParty($INPARTY as element(PARTY)) as element()*{

for $PARTY in collection("PARTY")/PARTY
where $PARTY/ID/text() = $INPARTY/ID/text()
return
<a:id>
{$PARTY/ID/text()}
</a:id>
union
<a:typeCode>
<b:value>
{$PARTY/TYPECODE/text()}
</b:value>
</a:typeCode>
};

let $SRCHPARTY := collection("PARTY")/PARTY[ID = $partyID]
return
<a:listOfParty>
<a:party>
{local:getParty($SRCHPARTY)}
</a:party>
</a:listOfParty>

Hope this helps
