How to join two documents from two different collections?

  • 1.  How to join two documents from two different collections?

    Posted Fri December 05, 2003 03:31 PM

    Dear Tamino XQuery Forum Members.

    I am using tamino 4.1.4.

    It looks like xquery and x-query restricts you to operate on only one collection.

    Suppose I have two documents in two different collections, and that each document has an attribute named “id”.


    1) Is it possible make a query that joins two documents from different collections?

    2) If so how?

    Thanks in advance.

    Best Regards
    Stefan Krabbe

    Hello,
    this is currently not possible.
    The functionality will be available in V4.2 with
    the support of the collection() function of XQuery.
    Instead of the currently used input() function, you can then use the collection() function to
    access and join documents from different collections.
