cts.min

cts.min(
   range-index as cts.reference,
   [options as String[]],
   [query as cts.query?],
   [forest-ids as (Number|String)[]]
) 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.

Parameters
range-index Reference to a range index.
options Same as the "options" parameter in cts:aggregate.
query Same as the "query" parameter in cts:aggregate.
forest-ids Same as the "forest-ids" parameter in cts:aggregate.

Example

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

cts.min(cts.elementReference(xs.QName("Amount")))

=> 59.95000000000000125
