Error in component tDBOutput_1 java.sql.SQLException: No database selected

Hello everyone,

I am new to Talend and want to execute a Job but I encountered an error. I don't exactly understand where the problem is. For me, normally the error shouldn't occur. Can someone help me please ?

Starting job write_movies_to_db at 17:26 10/03/2022.

Hello,

Are you able to create a mysql database connection, and retrieve schema successfully?

Here is online documentation about: TalendHelpCenter: Centralizing database metadata

Please change your connection string to make it connect to the right database on localhost (such as, jdbc:mysql://localhost:3306/.... instead of 127.0.0.1).

Best regards

Sabrina

Hi

Set the port as "3306", append parameter "serverTimezone=UTC#" to Additional JDBC parameters filed in the advanced settings panel of tMysqlOutput component.
