Error on connecting MySQL with Java with Connector/J on ubuntu

Question

I'm trying to do the project explained enter link description here(the code is at the end of the page), but when I run it is risen the error:

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: SELECT command denied to user 'sqluser'@'localhost' for table 'COMMENTS'

I think that the error could be related at the CLASSPATH but I'm not sure at all. What could be the cause of this error and how could I solve it?

Answer 1

The root cause of this error is quite plainly explained :

SELECT command denied to user 'sqluser'@'localhost' for table 'COMMENTS'

Just be sure to create a mysql user named sqluser and grant it the appropriate rights on the 'COMMENTS' table.

Quick and dirty : GRANT ALL PRIVILEGES ON your_db_name.* TO 'sqluser'@localhost IDENTIFIED BY 'sqluserpw';
