Hi guys!

I am using Talend for integrating MySQL DB connection for importing the excel data.

Scenario...

I have two excel file and I want to import both excel file data in my MYSQL database.

when I run the job it showing the error bellow-

Sun Mar 15 22:19:36 PDT 2020 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

Which version of Talend are you using? and it is saying that Access denied,are you sure right credentials?

Note that you are receiving : Access denied for user ''@'localhost' (using password: NO)

You are facing permission issues.

Try to create a new user in your mysql database with oermission to @'%' and set this user in your tDBInput
