An intermediate step in the construction of aWindowSpecification
.Example:
WindowSpecification spec = DSL.partitionBy(BOOK.AUTHOR_ID) .orderBy(BOOK.ID) .rowsBetweenUnboundedPreceding() .andCurrentRow();
Referencing
XYZ*Step
types directly from client codeIt 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
