Kam ChanSubject: DataDirect process getting XPST0005 error
Author: Kam Chan

Hi,

I am getting various "Static error" when I try to run my xQuery with DataDirect processor.

The simple example receives the following error:

[DataDirect][XQuery][err:XPST0005]Error at line 16, column 51. Static error. The static type of step 'parent::node()' is empty-sequence(). [Call stack: local:getNode@21.4]

xQuery code:
declare variable $system :=
<root>
<a>
<b>b2</b>
<c>c1</c>
</a>
<a>
<b>b3</b>
<c>c2</c>
<d/>
</a>
</root>;

declare function local:getNode($system as element(), $node as element()*, $noNode as element()*) as element()*
{
let $myNode := if (exists($noNode)) then $noNode/../.. else $node/..
return $myNode
};

<result>
{ local:getNode($system, $system/a/d, () ) }
</result>

The getNode() function accepts two sets of elements, and depending whether one set is empty, it retrieves the parent or grand-parent of another set.

But when I call this function with an empty sequence, DataDirect throws this exception. My intention was that the function should catch the empty sequence condition. How can I make this to work with DataDirect?

Thanks
Kam

Hi Kam,
you can turn off the detection of type mismatch by adding a

declare option ddtek:detect-XPST0005 "no";

at the beginning of your query.

Hope this helps,
Alberto
