Can anyone help about this problem. I am using flink sql-client. the flink cluster in deployed by docker-compose. and I have cp some jars to the lib folder in every container in flink cluster. My purpose is to test flink sql-cli to copy mysql data to another mysql table with same filed and type.

Which Flink version are you using? The options you're using have been removed in recent versions. It should be something like

) WITH (
   'connector' = 'jdbc',
   'url' = 'jdbc:<mysql://mysql:3306/sql-demo>',
   'table-name' = 'history',
   'username' = 'flink-only-sql',
   'password' = 'demo-sql'
);
