Question

I know that MySQL supports this query (ON DUPLICATE KEY UPDATE) for example:

INSERT INTO UserFailure (Realm, Username, DateOfFailure, CountOfFailure) VALUES (?,?,?,?) ON DUPLICATE KEY UPDATE CountOfFailure=?;

When I am running this on embedded Derby DB it gives me:

PreparedStatementCallback; bad SQL grammar [INSERT INTO UserFailure (Realm, Username, DateOfFailure, CountOfFailure) VALUES (?,?,?,?) ON DUPLICATE KEY UPDATE CountOfFailure=?;]; nested exception is java.sql.SQLSyntaxErrorException: Syntax error: Encountered "ON" at line 1, column 91.

I assume that Derby does not support this feature.

Is there a query I can use to update the database record on duplicate key from Derby and from MySQL?

Answer 1

You can catch the duplicate key exception yourself, and issue the update.
