Error in the Logical dataservice for ODSI

Question

Hi Mike,
I have created a Physical dataservice(calling function from database ) as sample.ds and Logical layer as SampleTest1.ds
SampleTest1.ds : -
xquery version "1.0" encoding "UTF-8";
(::pragma xfl <x:xfl xmlns:x="urn:annotations.ld.bea.com"><creationDate>2010-11-09T12:43:51</creationDate></x:xfl> ::)
declare namespace tra= "ld:Physical/sample";
declare namespace tns="ld:Logical/REAFirmInfo/sampleTest1";
(::pragma function <f:function kind="library" visibility="public" isPrimary="false" xmlns:f="urn:annotations.ld.bea.com"/>::)
declare function tns:getTrueTradeName($busId as xs:integer) as xs:string ? {
for $busname in tra:get_trade_name($busId)
return
$busname
I am getting the following error.
com.bea.dsp.das.exception.DASException: weblogic.xml.query.exceptions.XQueryStaticException: ld:Logical/REAFirmInfo/sampleTest1.ds, line 13, column 5: {bea-err}FUNC001: "{ld:Physical/sample}get_trade_name": unbound external function.

Kindly help on this issue.

Answer 1

since the function is defined in your db, it only makes sense in a query that gets data from you database
the xquery for that would be something like ...
for $business_row in BUSINESS_TABLE()
where $business_row/BUS_ID = $mycode
return
get_trade_name( $business_row/BUS_ID )
then ODSI can generate the sql ...
select get_trade_name ( BUS_ID ) from BUSINESS_TABLE where BUS_ID = ?
