Interface MergeMatchedSetMoreStep<R extends Record>

All Superinterfaces:
Attachable, AttachableQueryPart, AutoCloseable, Flow.Publisher<Integer>, Merge<R>, MergeFinalStep<R>, MergeMatchedDeleteStep<R>, MergeMatchedSetStep<R>, MergeMatchedStep<R>, MergeMatchedWhereStep<R>, MergeNotMatchedStep<R>, Publisher<Integer>, org.reactivestreams.Publisher<Integer>, Query, QueryPart, RowCountQuery, Serializable, Statement
public interface MergeMatchedSetMoreStep<R extends Record> extends MergeMatchedSetStep<R>, MergeMatchedWhereStep<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
