op:min

op:min(
   $outCol as item(),
   $inCol as item()
) as map:map

Summary

This function gets the smallest non-null value of the column for the rows in the group or row set. The result is used for building the parameters used by the op:group-by function.

Parameters
$outCol The name to be used for the smallest value.
$inCol The column to be aggregated. The column can be named with a string or a column function such as op:col, op:view-col, or op:schema-col, or constructed from an expression with the op:as function.

Example

xquery version "1.0-ml";

import module namespace op="http://marklogic.com/optic"
     at "/MarkLogic/optic.xqy";

let $expenses := op:from-view("main", "expenses")

return $expenses
	          => op:group-by("Category", op:min("Minimum Spent", "Amount"))
	          => op:order-by("Category")
	          => op:result()
