Not Implemented by SQLite JDBC driver

kasboh · October 23, 2023, 11:05am

Hi, I’m trying to test Hiberante 6 and SQLite together with Java 17.
Currently I get the error:

Exception in thread "main" org.hibernate.exception.GenericJDBCException: Unable to extract generated-keys ResultSet [not implemented by SQLite JDBC driver] [insert into Message (text) values (?)]

though I don’t think that this is a real problem (I doub’t that insert method is not implemented in SQLite JDBC driver)

any ideas what can be the problem?

Well, the error is pretty self-explanatory. The SQLite JDBC driver does not support returning generated values from insert statements, so there is no way to fetch a generated identifier through JDBC means. Since SQLite is a single user database, this is usually not a problem since you should be able to just query the maximum id or something like that, which I assume the dialect does anyway. It’s strange though that you even see this message since SQLiteDialect#getDefaultUseGetGeneratedKeys() returns false. Can you please post the full stack trace?

What is your configuration? It seems you have wrongly configured hibernate.jdbc.use_get_generated_keys=true.

kasboh · October 23, 2023, 7:54pm

this property was not in the configuration (original hibernate config xml is in the first post)
now I added hibernate.jdbc.use_get_generated_keys = false and it seems to work fine.
Thanks a lot for your help!

It’s odd because this property should be enabled by default unless you override it. Also see SQLiteDialect#getDefaultUseGetGeneratedKeys.

I just released a version of the SQLite driver that supports JDBC 4.1 and getGeneratedKeys():

sqlite-jdbc-3.45.1.6-SNAPSHOT.jar
