How It Affects Your App
MySQL 3174 ER_CANNOT_ADD_FOREIGN_BASE_COL_VIRTUAL prevents the addition of a foreign key to a virtual column. This can have a significant impact on an application as it prevents the use of foreign keys to enforce data integrity. Without foreign keys, the application must rely on other methods to ensure data accuracy and consistency. This can lead to data inconsistencies and errors, which can be difficult to debug and fix.
How To Fix
1. SHOW VARIABLES LIKE 'max_connect_errors'; This command will show the current value of the max_connect_errors variable.
2. SET GLOBAL max_connect_errors=10000; This command will set the max_connect_errors variable to a higher value, allowing more connection attempts before MySQL will abort the connection.
3. FLUSH PRIVILEGES; This command will flush the privileges, ensuring that the new value of the max_connect_errors variable is applied.
4. SHOW VARIABLES LIKE 'max_connect_errors'; This command will show the new value of the max_connect_errors variable.
