How It Affects Your App
MySQL 1068 ER_MULTIPLE_PRI_KEY indicates that multiple primary keys have been defined for a table. This can cause issues with data integrity, as the database will not be able to determine which primary key should be used to uniquely identify a row. This can lead to data inconsistency and incorrect results when querying the database. Additionally, it can cause issues with data manipulation, as the database will not be able to determine which primary key should be used to update or delete a row.
How To Fix
1. Check the error log for the MySQL 1068 error. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'log_error';
2. Check the error log file for the MySQL 1068 error. This can be done by running the following command:

4. Check the MySQL configuration file for any errors. This can be done by running the following command:

5. Check the MySQL user privileges. This can be done by running the following command:
