op.min

op.min(
   aggColName as String,
   columndef as ColumnIdentifier
) as aggregatedef

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 prototype.groupBy function.

Parameters
aggColName The name to be used for the smallest value.
columndef The column to be aggregated. The column can be named with a string or a column function such as op.col, op.viewCol, or op.schemaCol, or constructed from an expression with the op.as function.

Example

const op = require('/MarkLogic/optic');

op.fromView('main', 'expenses')
   .groupBy('Category', op.min("Minimum Spent", "Amount"))
   .orderBy('Category')
   .result();
