MYSQL connector issue

Hi All,

Im facing a problem from mysql connector connecting to MariaDB version 11.0.1 with the Database Dialect: MySQL and i tried with the driver name: MySQL 5, MySQL 8 or MySQL v8.0.29 but i have no luck to get it connect and system show the error message below:

ERROR MySQL Connector 3:255 Execute failed: Unknown system variable ‘transaction_isolation’

Is anyone facing the same issue ? or solution so far?

Seems you need to register your own JDBC driver. Take a look at this topic:



Ipazin, Thanks for the info. Will test the two version of jdbc .jar file from the MariaDB website.
