Class IntervalYearToMonth

java.lang.Object

com.exasol.datatype.value.AbstractInterval

com.exasol.datatype.value.IntervalYearToMonth

public final class IntervalYearToMonth
extends AbstractInterval

This class implements the Exasol-proprietary data type value INTERVAL YEAR(x) TO MONTH(y). It supports conversions to and from strings and from a number of months.

In Exasol this data type represents a time difference consisting of the following components:

• years
• months

Since months are the highest resolution, each interval can also be expressed as a total number of months. This is also the recommended way to represent the interval values in other systems which do not natively support this data type.
