Class YearMonthIntervalType

Object
org.apache.spark.sql.types.DataType
org.apache.spark.sql.types.YearMonthIntervalType
All Implemented Interfaces:
Serializable, scala.Equals, scala.Product
public class YearMonthIntervalType extends DataType implements scala.Product, Serializable
The type represents year-month intervals of the SQL standard. A year-month interval is made up of a contiguous subset of the following fields: - MONTH, months within years [0..11], - YEAR, years in the range [0..178956970].

YearMonthIntervalType represents positive as well as negative year-month intervals.

param: startField The leftmost field which the type comprises of. Valid values: 0 (YEAR), 1 (MONTH). param: endField The rightmost field which the type comprises of. Valid values: 0 (YEAR), 1 (MONTH).
