Hi Veeramani Chellapandiyan,
Use below url for MySql connection:
jdbc:google:mysql://localhost:3306/[dbName]
ex, jdbc:mysql://localhost:3306/sql_mendix
Hope this helps you!
You have to place the respective SQL connector JAR file in the project ‘userlib’ folder
It should be version compatible. Error itself explains that it failed to detect driver instance. Try with latest version jar for MySQL.
