Interface WindowPartitionByStep<T>

Type Parameters:

T - The function return type

All Superinterfaces:

Field<T>, FieldOrConstraint, FieldOrRow, FieldOrRowOrSelect, GroupField, Named, OrderField<T>, QueryPart, SelectField<T>, SelectFieldOrAsterisk, Serializable, TableElement, Typed<T>, WindowFinalStep<T>, WindowOrderByStep<T>

public interface WindowPartitionByStep<T>
extends WindowOrderByStep<T>

This type is used for the window function DSL API.

Example:

field.firstValue()
     .ignoreNulls()
     .over()
     .partitionBy(AUTHOR_ID)
     .orderBy(PUBLISHED_IN.asc())
     .rowsBetweenUnboundedPreceding()
     .andUnboundedFollowing()
