Interface WindowSpecificationPartitionByStep

  • All Superinterfaces:
    QueryPart, java.io.Serializable, WindowSpecification, WindowSpecificationFinalStep, WindowSpecificationOrderByStep, WindowSpecificationRowsStep

    public interface WindowSpecificationPartitionByStep
    extends WindowSpecificationOrderByStep
    An intermediate step in the construction of a WindowSpecification.

    Example:

     WindowSpecification spec =
     DSL.partitionBy(BOOK.AUTHOR_ID)
        .orderBy(BOOK.ID)
        .rowsBetweenUnboundedPreceding()
        .andCurrentRow();
     

    Referencing XYZ*Step types directly from client code

    It is usually not recommended to reference any XYZ*Step types directly from client code, or assign them to local variables. When writing dynamic SQL, creating a statement's components dynamically, and passing them to the DSL API statically is usually a better choice. See the manual's section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.

    Drawbacks of referencing the XYZ*Step types directly:

    • They're operating on mutable implementations (as of jOOQ 3.x)
    • They're less composable and not easy to get right when dynamic SQL gets complex
    • They're less readable
    • They might have binary incompatible changes between minor releases
