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

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.

Let me rephrase that:  If you are backing up or loading the same or
similar sets of documents and directories it might be easier to create
an XML configuration file that you can pass for each run.

David,

 

Have you thought about creating a simple XML document and passing that
to your xquery?

 

Might be easier.  Especially if the documents you load are similar
and/or configurable.

 

Just a thought.

I got one step further with this.   the 3 arg setNewVariable is already
calling  valueVactory.newSequence

I got further by replacing it with this

 

     request.setNewVariable( new XName("", "dirs"),
ValueFactory.newSequence(dirs.toArray(new XdmValue[dirs.size()])));

     

 

Now I got 

 

com.marklogic.xcc.exceptions.UnimplementedFeatureException: Setting
variables that are sequences is not supported

 

 

So I guess sequences are not supported ... 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 ...

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 ?
