INSERT .. ON DUPLICATE KEY UPDATE .. EXCLUDED

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

Starting with MySQL 8, there's support for aliasing the INSERT .. VALUES clause in order to reference its columns from the ON DUPLICATE KEY UPDATE clause:

INSERT INTO AUTHOR (ID, LAST_NAME)
VALUES
  (3, 'Koontz'),
  (4, 'Shakespeare') AS t   -- Declare source data alias
ON DUPLICATE KEY UPDATE
SET last_name = t.last_name -- Reference source data alias

jOOQ does not explicitly support this syntax in the DSL API, but the PostgreSQL specific equivalent from INSERT .. ON CONFLICT .. EXCLUDED can be emulated in MySQL as well, so you can just use the DSL.excluded() pseudo table:

// Add a new author called "Koontz" with ID 3.
// If that ID is already present, update the author's name
create.insertInto(AUTHOR, AUTHOR.ID, AUTHOR.LAST_NAME)
      .values(3, "Koontz")
      .values(4, "Shakespeare")
      .onDuplicateKeyUpdate()
      .set(AUTHOR.LAST_NAME, excluded(AUTHOR.LAST_NAME))
      .execute();

Dialect support

This example using jOOQ:

insertInto(AUTHOR, AUTHOR.ID, AUTHOR.LAST_NAME).values(3, "X").onDuplicateKeyUpdate().set(AUTHOR.LAST_NAME, excluded(AUTHOR.LAST_NAME))

Translates to the following dialect specific expressions:

Aurora MySQL, MariaDB, MemSQL

INSERT INTO AUTHOR (ID, LAST_NAME)
VALUES (
  3, 
  'X'
)
ON DUPLICATE KEY UPDATE
  AUTHOR.LAST_NAME = VALUES(LAST_NAME)

Aurora Postgres, CockroachDB, DuckDB, Postgres, YugabyteDB

INSERT INTO AUTHOR (ID, LAST_NAME)

  'X'

SET
  LAST_NAME = excluded.LAST_NAME
