 * This type is used for the {@link Merge}'s DSL API.
 * 

* Example:


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

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
