fn:unordered

fn:unordered(
   $sourceSeq as item()*
) as item()*

Summary

Returns the items of $sourceSeq in an implementation dependent order.

Note:

Query optimizers may be able to do a better job if the order of the output sequence is not specified. For example, when retrieving prices from a purchase order, if an index exists on prices, it may be more efficient to return the prices in index order rather than in document order.

Example

fn:unordered((1, 3, 2))

=> 1, 3, 2
