I guess that answers THAT question ... I cant send Nodes as variables either :( :(
Exception running: ml:query com.marklogic.xcc.exceptions.UnimplementedFeatureException: Setting variables of type XdmNode is not supported From: [email protected] [mailto:[email protected]] On Behalf Of Lee, David Sent: Sunday, March 14, 2010 10:06 AM To: General Mark Logic Developer Discussion Subject: RE: [MarkLogic Dev General] Problem creating a SEQUENCE in XCCtopassto xquery function Thanks for the suggestion, but in this case its a tool ("put" command from the marklogic extension module to xmlsh) where I dont know ahead of time what will be passed in, it could be 1 file or even xml expression, or 10million files in 1 million directories. I've gotten it to work by dynamically creating a (potentially huge) xquery statement which replicates the xquery commands one per argument instead of doing a loop. Its only 1 xquery command ( xdmp:directory-create( xxx ) ) . This seems to work well enough for small tasks, I'm not sure yet what its going to do when I try 1 million lines. Not sure if the cost of creating an xml docment containing 1 million elements and passing that to the ad-hoc script will be more or less efficient (including my side creating the document then the XCC code parsing it and the server reconstructing it), then it would be to generate send 1 million lines of xquery ... Its probably 'better' even if slower, to create the xml doc ... but I'd still like to be able to send a sequence like I'd expect any XQuery processor to be able to natively handle.

Might be easier. Especially if the documents you load are similar and/or configurable. Just a thought. Keith L.

UG ... Could I put in a feature request to support sequences for XCC xquery calls ? What I'm trying to do is avoid 10,000 calls to adHocQuery by passing in all the values as an argument. My next step will be to try create an Element as the argument instead of a sequence. Any chance elements are supported as variables in XCC ??? If that doesnt work then I suppose I'll serialize a huge XQuery document with in-line values to construct a sequence ... -David From: [email protected] [mailto:[email protected]] On Behalf Of Lee, David Sent: Saturday, March 13, 2010 10:04 PM To: General Mark Logic Developer Discussion Subject: [MarkLogic Dev General] Problem creating a SEQUENCE in XCC to passto xquery function I'm trying to create a SEQUENCE in XCC to pass to an ad-hoc xquery. I want a sequence of xs:string I create a linked-list of XdmValue using this : List<XdmValue> dirs = new LinkedList<XdmValue>(); ... XdmValue xdm = ValueFactory.newValue(ValueType.XS_STRING, uri); dirs.add(xdm); Then call this request.setNewVariable("dirs", ValueType.SEQUENCE, ValueFactory.newSequence(dirs.toArray(new XdmValue[dirs.size()]))); I get this exception : java.lang.IllegalArgumentException: Value must be array of XdmValue Inspecting dirs I find each entry is of type XsStringImpl which is implements XdmValue (indirectly) So I dont see where my problem is ... Any suggestions on making a sequence of strings to pass through XCC ? ---------------------------------------- David A. Lee Senior Principal Software Engineer Epocrates, Inc.
