/**
 * This type is used for the {@link Update}'s DSL API.
 * 
 * Example: 

 * DSLContext create = DSL.using(configuration);
 *
 * TableRecord<?> record =
 * create.update(table)
 *       .set(field1, value1)
 *       .set(field2, value2)
 *       .returning(field1)
 *       .fetchOne();
 * 
 * 
 * This implemented differently for every dialect:
 * 

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