INSERT .. ON DUPLICATE KEY UPDATE
Supported by ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The MySQL database supports a very convenient way to INSERT or UPDATE a record. This is a non-standard extension to the SQL syntax, which is supported by jOOQ and emulated in other RDBMS, where this is possible (e.g. if they support the SQL standard MERGE statement). Here is an example how to use the ON DUPLICATE KEY UPDATE clause:
// 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") .onDuplicateKeyUpdate() .set(AUTHOR.LAST_NAME, "Koontz") .execute();
Dialect support
This example using jOOQ:
insertInto(AUTHOR, AUTHOR.ID, AUTHOR.LAST_NAME).values(3, "X").onDuplicateKeyUpdate().set(AUTHOR.LAST_NAME, "X")
Translates to the following dialect specific expressions:
Aurora MySQL, MariaDB, MemSQL, MySQL
INSERT INTO AUTHOR (ID, LAST_NAME) VALUES ( 3, 'X' ) ON DUPLICATE KEY UPDATE AUTHOR.LAST_NAME = 'X'
Aurora Postgres, CockroachDB, DuckDB, Postgres, YugabyteDB
