min()

Returns the minimum value of a dimension or measure field.

Example - Find the Smallest Opportunity For Each Account

1q = load "Ops";
2q = group q by 'Account_Name';
3q = foreach q generate 'Company' as 'Company', min('Amount') as 'Smallest Deal';

Example - Find the First Value in List of Airline Destinations per Origin

For dimensions, min() sorts the values alphabetically and the first value is returned.

1q = load "Airlines";
2q = group q by 'origin';
3q = foreach q generate 'origin' as 'Origin', min('dest') as 'Min Destination';
