INSERT .. RETURNING

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The Postgres database has native support for an INSERT .. RETURNING clause. This is a very powerful concept that is emulated for all other dialects using JDBC's getGeneratedKeys() method. Take this example:

// Add another author, with a generated ID
Record record =
create.insertInto(AUTHOR, AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME)
      .values("Charlotte", "Roche")
      .returningResult(AUTHOR.ID)
      .fetchOne();

System.out.println(record.getValue(AUTHOR.ID));

// For some RDBMS, this also works when inserting several values
// The following should return a 2x2 table
Result<?> result =
create.insertInto(AUTHOR, AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME)
      .values("Johann Wolfgang", "von Goethe")
      .values("Friedrich", "Schiller")
      // You can request any field. Also trigger-generated values
      .returningResult(AUTHOR.ID, AUTHOR.CREATION_DATE)
      .fetch();

Some databases have poor support for returning generated keys after INSERTs. In those cases, jOOQ might need to issue another SELECT statement in order to fetch an @@identity value. Be aware, that this can lead to race-conditions in those databases that cannot properly return generated ID values. For more information, please consider the jOOQ Javadoc for the returningResult() clause.

Dialect support

This example using jOOQ:

insertInto(AUTHOR, AUTHOR.LAST_NAME).values("Doe").returningResult(AUTHOR.ID)

Translates to the following dialect specific expressions:

ASE, Access, Aurora MySQL, BigQuery, Derby, Exasol, HSQLDB, Hana, Informix, MemSQL, MySQL, Oracle, Redshift, Snowflake, Sybase, Teradata, Trino, Vertica

INSERT INTO AUTHOR (LAST_NAME)
VALUES ('Doe')

Aurora Postgres, CockroachDB, DuckDB, Firebird, Postgres, SQLite, YugabyteDB

INSERT INTO AUTHOR (LAST_NAME)
VALUES ('Doe')
RETURNING AUTHOR.ID

DB2, H2

SELECT ID
FROM FINAL TABLE (
  INSERT INTO AUTHOR (LAST_NAME)
  VALUES ('Doe')
) AUTHOR

MariaDB

INSERT INTO AUTHOR (LAST_NAME)
VALUES ('Doe')
RETURNING ID

SQLDataWarehouse, SQLServer

INSERT INTO AUTHOR (LAST_NAME)
OUTPUT inserted.ID
VALUES ('Doe')

(These are currently generated with jOOQ 3.20, see #10141), or translate your own on our website
