Interface MergeUsingStep<R extends Record>

  • All Superinterfaces:
    MergeKeyStepN<R>, MergeValuesStepN<R>

    public interface MergeUsingStep<R extends Record>
    extends MergeKeyStepN<R>
    This type is used for the Merge's DSL API.

    Example:

     DSLContext create = DSL.using(configuration);
    
     create.mergeInto(table)
           .using(select)
           .on(condition)
           .whenMatchedThenUpdate()
           .set(field1, value1)
           .set(field2, value2)
           .whenNotMatchedThenInsert(field1, field2)
           .values(value1, value2)
           .execute();
     

    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
