Interface WindowPartitionByStep<T>

Type Parameters:

T - The function return type

All Superinterfaces:

Field<T>, FieldOrRow, GroupField, QueryPart, SelectField<T>, Serializable, 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()

Method Detail

partitionBy

@Support(value={CUBRID,DB2,FIREBIRD_3_0,HANA,INFORMIX,POSTGRES,ORACLE,REDSHIFT,SQLSERVER,SYBASE,VERTICA})
WindowOrderByStep<T> partitionBy(Field<?>... fields)

Add a PARTITION BY clause to the window functions.

partitionByOne

@Support(value={CUBRID,DB2,FIREBIRD_3_0,HANA,INFORMIX,POSTGRES,ORACLE,REDSHIFT,SQLSERVER,SYBASE,VERTICA})
WindowOrderByStep<T> partitionByOne()

Add a PARTITION BY 1 clause to the window functions, where such a clause is required by the syntax of an RDBMS.

This clause is not supported as such in the CUBRID and Sybase dialects. If you use it, jOOQ will simply ignore it.
