Questions tagged [xquery-3.0]

Use this tag for questions specific to XQuery version 3.0 and no other version.

XQuery 3.0 introduces the following new features:

  • Functions are first-class items which can be passed as parameters to other functions

  • Functions and variables support public and private annotations

  • Union types are allowed in function arguments

  • XML Schema 1.1 is supported

  • Clauses added to FLWOR expressions:

    • group by: assigns tuples in the input tuple stream to a group, returns a tuple for each group

    • tumbling window: destructing assignment of a sequence during iteration without intersection

    • sliding window: destructing assignment of a sequence during iteration with intersection

    • count clause: binds a variable to the position in each tuple in the tuple stream

    • allowing empty: facilitates outer joins as in SQL

  • decimal format declaration: adds a decimal format to the statically known decimal formats

  • try/catch expressions: allows for user defined recovery from errors

  • switch expressions: allows for user defined branching logic
