cts:min

cts:min(
   $range-index as cts:reference,
   [$options as xs:string*],
   [$query as cts:query?],
   [$forest-ids as xs:unsignedLong*]
) as xs:anyAtomicType?

Summary

Returns the minimal value given a value lexicon. This function performs the calculation in parallel in all data nodes then aggregates the values. It generally performs better than fn:min, especially on large clusters.

Example

xquery version "1.0-ml";

  (:
     This query assumes an element range index is configured
     in the database for the 'Amount' element.
  :)

cts:min(cts:element-reference(xs:QName("Amount")))
