Class DayTimeIntervalType

Object
org.apache.spark.sql.types.DataType
org.apache.spark.sql.types.DayTimeIntervalType
All Implemented Interfaces:
Serializable, scala.Equals, scala.Product, scala.Serializable
public class DayTimeIntervalType extends DataType implements scala.Product, scala.Serializable
The type represents day-time intervals of the SQL standard. A day-time interval is made up of a contiguous subset of the following fields: - SECOND, seconds within minutes and possibly fractions of a second [0..59.999999], - MINUTE, minutes within hours [0..59], - HOUR, hours within days [0..23], - DAY, days in the range [0..106751991].

DayTimeIntervalType represents positive as well as negative day-time intervals.

param: startField The leftmost field which the type comprises of. Valid values: 0 (DAY), 1 (HOUR), 2 (MINUTE), 3 (SECOND). param: endField The rightmost field which the type comprises of. Valid values: 0 (DAY), 1 (HOUR), 2 (MINUTE), 3 (SECOND).
