MySQL 1818

This error indicates that the length of the year column is invalid in MySQL 1818. It is a reminder to check the length of the column to ensure it is valid.

How It Affects Your App

The error ER_INVALID_YEAR_COLUMN_LENGTH indicates that the length of the year column in the MySQL database is not valid. This can have a significant impact on the application as it may cause data to be stored incorrectly or not at all. This can lead to incorrect results when querying the database, or even cause the application to crash. It is therefore important to ensure that the length of the year column is valid in order to ensure the application runs smoothly.

4. Check the MySQL user table to see if there are any users that shouldn't have access:
$ mysql -u root -p -e "SELECT User, Host FROM mysql.user;"
5. Check the MySQL grants table to see if there are any grants that shouldn't be in place:
$ mysql -u root -p -e "SELECT * FROM mysql.db;"
6. Restart the MySQL service to apply any changes made:
