org.apache.drill.exec.expr.fn.impl.GAge.AgeDateToMidnight

All Implemented Interfaces:

DrillFunc, DrillSimpleFunc

Enclosing class:

GAge

public static class GAge.AgeDateToMidnight
extends Object
implements DrillSimpleFunc

Unary form, subtracts `right` from midnight so equivalent to `select age(current_date, right)`. Note that this function does not count calendar boundary crossings, e.g. between yesterday 23:00 and today 01:00 is two hours, not one day. Modeled on the AGE function in PostgreSQL, see https://www.postgresql.org/docs/current/functions-datetime.html.
