[MarkLogic Dev General] distinct-nodes() in marklogic 4.1-2

[Jason Booth]

Hi Ashwini,

You are alllowed to mix xquery dialects, which will give you access to the fn:distinct-nodes() function. Basically, you can write a library module in the "0.9-ml" dialect, that includes a function using fn:distinct-nodes(), and import that for use in your "1.0-ml" module. Just remember to include the xquery dialect version in your prolog (always good practice). For further details, this is documented in the XQuery Ref Guide, as follows:

http://developer.marklogic.com/pubs/4.1/books/xquery.pdf

2.2 Rules For Combining the Dialects

MarkLogic Server has a very flexible way of combining the three XQuery dialects. You can
import a library module written in any of the three dialects into any main or library module. For
example, you might find an open source standards-compliant module that you found on the
internet which is written in the strict XQuery 1.0 dialect. You can then import this module into
any MarkLogic Server XQuery program, regardless of dialect, and then use those functions in
your code.

When writing modules of different dialects, the best practice is to always use the XQuery version
declaration as the first line, indicating which dialect the module is written in. That way, if the
module is written in a different dialect than the default dialect for the App Server or the program,
it will still work correctly (for details, see “Inheriting the Default XQuery Version From the App
Server” on page 11).

NOTE: One other thing to mention, in "0.9-ml" there's a subtle difference in the dialect, namespace declarations and imports - no semicolons are used at the end of the declaration, as there is in "1.0-ml".

Regards,

Jason
