Interface UpdateFromStep<R extends Record>

All Superinterfaces:
Attachable, AttachableQueryPart, AutoCloseable, Flow.Publisher<Integer>, Publisher<Integer>, org.reactivestreams.Publisher<Integer>, Query, QueryPart, RowCountQuery, Serializable, Statement, Update<R>, UpdateFinalStep<R>, UpdateLimitStep<R>, UpdateOrderByStep<R>, UpdateReturningStep<R>, UpdateWhereStep<R>
All Known Subinterfaces:
UpdateSetMoreStep<R>
public interface UpdateFromStep<R extends Record> extends UpdateWhereStep<R>
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
