Interface UpdateSetStep<R extends Record>

  • All Known Subinterfaces:
    UpdateSetFirstStep<R>, UpdateSetMoreStep<R>
    public interface UpdateSetStep<R extends Record>
    This type is used for the Update's DSL API.

    Example: 

     DSLContext create = DSL.using(configuration);

 create.update(table)
       .set(field1, value1)
       .set(field2, value2)
       .where(field1.greaterThan(100))
       .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

    • Method Detail

      • setNull

        @NotNull
@Support
<T> @NotNull UpdateSetMoreStep<R> setNull​(Field<T> field)
        Set a null value for a field in the UPDATE statement.

        This method is convenience for calling set(Field, Object), without the necessity of casting the Java null literal to (T).

      • set

        @NotNull
@Support
@NotNull UpdateSetMoreStep<R> set​(Map<?,​?> map)
        Set a value for a field in the UPDATE statement.

        Keys can either be of type String, Name, or Field.

        Values can either be of type <T> or Field<T>. jOOQ will attempt to convert values to their corresponding field's type.

      • set

        @NotNull
@Support
@NotNull UpdateSetMoreStep<R> set​(Record record)
        Set a value for a field in the UPDATE statement.

        This is the same as calling set(Map) with the argument record treated as a Map<Field<?>, Object>, except that the Record.changed() flags are taken into consideration in order to update only changed values.
