Exasol Dialect for Hibernate 6+?

I am looking for a solution to use Exasol database from SpringBoot 3.1 by Hibernate 6.2+. There was a project at GITHUB for hibernate 5, but that dialect no longer compilable. Syntax changed a lot. Some forum entry says for other databases as custom dialect not needed anymore.
Can you please help me where else to look for infos?

Dialects for non-officially supported databases are maintained by the community through voluntary contributions in a separate module, see the Hibernate 6.0 migration guide for more details.

I’m not sure if there was a working version of an Exasol database dialect with Hibernate 5, but your best bet would be trying to port / implement a compatible version for 6 and we would be really happy to include it in the the community module.

thanks for the update.

I can confirm this GIT project was working nicely with util SpringBoot 2.7.x (hibernate 5). That project is provided by EXASOL guys.

If no better idea, then I will need to migrate to hibernate6 if want to proceed with SpringBoot3.1.


The repository is archived and not maintained anymore. You should contact Exasol and talk with them about this if you care about Hibernate support. Also point them to this document: https://github.com/hibernate/hibernate-orm/blob/main/dialects.adoc

Hi there again,

as no longer supported (available) exasol-jdbc6 even our workaround is trashed.

The current (7.1.20 mvn central exasol-jdbc) driver is complaining as:

 WARN  c.z.h.p.ProxyConnection - HikariPool-1 - Connection com.exasol.jdbc.EXAConnection@_____ marked as broken because of SQLSTATE(0A000), ErrorCode(0)
com.exasol.jdbc.NotImplemented: Feature not supported - Auto-generated keys.

However executed native SQL (via JDBC in DataGrip Tool), just working fine:

values ('testme', 1, '0:0:0:0', systimestamp);

Tried forcing my Sql to do the same via annotation:

@SQLInsert(sql=“insert into myapp_security_log (email,id_result,ip_address,logon_date) values (?,?,?,?)”)

Is there any way to ask hibernate to ignore jdbc-drivers (exasol-jdbc) complaint about “not supported” and just let the basic sql to run?


You can disable the use of auto-generated keys: https://docs.jboss.org/hibernate/orm/6.4/userguide/html_single/Hibernate_User_Guide.html#settings-hibernate.jdbc.use_get_generated_keys
