Interface DeleteResultStep<R extends Record>

  • All Superinterfaces:
    Attachable, AttachableQueryPart, AutoCloseable, Flow.Publisher<R>, Iterable<R>, Publisher<R>, org.reactivestreams.Publisher<R>, Query, QueryPart, ResultQuery<R>, Serializable, Statement

    public interface DeleteResultStep<R extends Record>
    extends ResultQuery<R>
    This type is used for the Delete's DSL API.

    Example:

     DSLContext create = DSL.using(configuration);
    
     create.delete(table)
           .where(field1.greaterThan(100))
           .execute();
     

    This implemented differently for every dialect:

    • Firebird and Postgres have native support for UPDATE .. RETURNING clauses
    • DB2 allows to execute SELECT .. FROM FINAL TABLE (DELETE ...)

    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
