How It Affects Your App
MySQL 1302 ER_CONFLICTING_DECLARATIONS can cause an application to fail when attempting to create a database object. This error occurs when two or more conflicting declarations are found in the same statement. This can lead to unexpected results and can cause the application to crash or become unstable. It can also lead to data corruption or data loss, which can be difficult to recover from. As a result, it is important to ensure that all database objects are properly declared and that there are no conflicting declarations.

$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:

3. Check the MySQL database for any corrupt tables:
$ mysqlcheck -u root -p --all-databases
4. Check the MySQL database for any missing tables:
$ mysqlshow -u root -p
5. Check the MySQL database for any missing indexes:
