Interface InsertResultStep<R extends Record>

All Superinterfaces:

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

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

This type is used for the Insert's DSL API.

Example:

 Factory create = new Factory();

 TableRecord record =
 create.insertInto(table, field1, field2)
       .values(value1, value2)
       .returning(field1)
       .fetchOne();
 

This implemented differently for every dialect:

• Firebird and Postgres have native support for INSERT .. RETURNING clauses
• HSQLDB, Oracle, and DB2 JDBC drivers allow for retrieving any table column as "generated key" in one statement
• Derby, H2, Ingres, MySQL, SQL Server only allow for retrieving IDENTITY column values as "generated key". If other fields are requested, a second statement is issued. Client code must assure transactional integrity between the two statements.
• Sybase and SQLite allow for retrieving IDENTITY values as @@identity or last_inserted_rowid() values. Those values are fetched in a separate SELECT statement. If other fields are requested, another statement is issued. Client code must assure transactional integrity between these statements.

Method Detail

fetch

@Support
Result<R> fetch()
                               throws DataAccessException

The result holding returned values as specified by the InsertReturningStep

This currently only works well for DB2, HSQLDB, MySQL, and Postgres

Returns:

The returned values as specified by the InsertReturningStep. Note:

• Not all databases / JDBC drivers support returning several values on multi-row inserts!
• 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

InsertQuery.getReturnedRecords()

fetchOne

@Support
R fetchOne()
                          throws DataAccessException

The record holding returned values as specified by the InsertReturningStep

Returns:

The returned value as specified by the InsertReturningStep. This may return null in case jOOQ could not retrieve any generated keys from the JDBC driver.

Throws:

DataAccessException - if something went wrong executing the query
