MySQL Error 1239, who cannot avoid it when using MySQL database! It reads like this: “Error 1239 (42000): Access denied; you need the CONVERT_ERROR_TO_WARNING_WITH_QUERY_LOGGING system privilege to be able to log such warnings”

This error appears when a user attempts to use a SET SQL statement without the proper privileges. This statement is used to change the value of global variables in the database, such as the character set or query logging settings. If a user has an insufficient privilege level, such as after a database restore, they will likely encounter this error.

Fortunately, it’s easy to fix MySQL Error 1239. Here I’ll share with you the steps to follow.

3. Replace “user_name” and “host_name” with the actual names given for your user and host.
