Ambika,
Here's a trick, though it's cleaner to use something like XQuery unit that can
actually test using HTTP requests.
"declared" variables are lazily evaluated, and won't throw an error if they are
missing, until they are actually accessed. So you can prevent the access of an
external variable by checking for an HTTP field first. If called using XCC
there will be no HTTP field, so the external parameter will be used.
xquery version "1.0-ml";
declare variable $p external;
let $p-http := xdmp:get-request-field("p", "")
let $p-actual := if ($p-http ne "") then "p as http" else ($p)
return $p-actual
Test from a browser or http client with: http://localhost:9301/test.xqy?p=x
test from cq with: xdmp:invoke("/test.xqy", (xs:QName("p"), "z"))

Subject: [MarkLogic Dev General] Handling request parameter in both xcc and
http connection
Hi all,
I have a xquery file which has xdmp:get-request-field to get one of its
parameters when it is accessed via the HTTP server, the same xquery file is
access by a xdbc server for testing so i am using
declare variable $keyword as xs:string as external
to retrieve the value of parameter from the xdbc connection to pass on to the
xquery.
I would like this xquery file to handle both the request depending on the
requirement.
Using the xcc connection in the java environment I am using
Request requestURL = session.newModuleInvoke("datefile.xqy" );
requestURL.setNewStringVariable("node-string", "filename");
ResultSequence sequence = session.submitRequest(requestURL);
and in the xquery I am using
declare variable $node-string as xs:string as external;
and then using the variable $node-string
I want to make the xquery in such a way that it accepts and handles both the
requests without any issues
Regards
Ambika
