Interface UpdateResultStep<R extends Record>

All Superinterfaces:

Attachable, Insert<R>, Query, QueryPart, Serializable

public interface UpdateResultStep<R extends Record>
extends Insert<R>

This type is used for the 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

• This may return an empty Result in case jOOQ could not retrieve any generated keys from the JDBC driver.

Throws:

DataAccessException - if something went wrong executing the query

                                         throws DataAccessException
