The MySQL JDBC (v3.1.10) drivers included with ADS work across all versions of MySQL from 3.x to 4.1. MySQL server releases are very frequent, and may sometimes require updating the JDBC driver.
You may locate the latest MySQL JDBC drivers at the following location ...

Vendor: MySQL
Driver URL: http://www.mysql.com/products/connector/j/

To update the ADS JDBC drivers you need to overwrite the ADS mysql.jar file. Below is a listing of the Aqua Data Studio library directory [ADS_HOME]\lib\drivers\ ...

Driver Location (Windows/Linux):
[ADS_INSTALL]\lib\drivers\mysql.jar
