How to check error in MySQL?

To check errors in MySQL, the best approach is to enable the general query log. This is done by setting the global variable log_output to ‘FILE’ and log_error to the destination of the log file. Once this is done, the next step is to set the global variable log_error_verbosity to 2, which is the default value. This setting ensures that all errors, warnings and other messages are logged.

Once these steps are completed, all errors encountered by the server will be written to the log file, allowing for individual errors to be identified and addressed. It is important to remember to periodically monitor the log file, as errors may build up over time without being noticed.

In summary, the best way to check errors in MySQL is to enable the general query log, with the log_error_verbosity set to 2. This will allow errors to be identified, tracked and resolved in a timely manner.
