INSERT .. ON DUPLICATE KEY IGNORE

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

The MySQL database also supports an INSERT IGNORE INTO clause. This is supported by jOOQ using the more convenient SQL syntax variant of ON DUPLICATE KEY IGNORE:

// Add a new author called "Koontz" with ID 3.
// If that ID is already present, ignore the INSERT statement
create.insertInto(AUTHOR, AUTHOR.ID, AUTHOR.LAST_NAME)
      .values(3, "Koontz")
      .onDuplicateKeyIgnore()
      .execute();

If the underlying database doesn't have any way to "ignore" failing INSERT statements, (e.g. MySQL via INSERT IGNORE), jOOQ can emulate the statement using a MERGE statement, or using INSERT .. SELECT WHERE NOT EXISTS.

The MySQL INSERT IGNORE statement ignores more constraint violations than just duplicate keys, so the emulation isn't exactly equivalent, see #5211

Dialect support

This example using jOOQ:

insertInto(AUTHOR, AUTHOR.ID, AUTHOR.LAST_NAME).values(3, "X").onDuplicateKeyIgnore()

Translates to the following dialect specific expressions:
