MySQL 1293

This error occurs when too many columns are defined as auto-timestamp columns in a table. It indicates that the maximum number of auto-timestamp columns has been exceeded.

How It Affects Your App

This error indicates that the application is attempting to create more than one TIMESTAMP column with the DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP attributes. This can cause issues with the application's data integrity, as multiple columns with the same attributes can lead to unexpected results. Additionally, it can cause performance issues, as the database must update multiple columns when a row is modified. This can lead to slower query execution times and increased resource usage.

How To Fix

1. Identify the source of the MySQL 1293 error:SELECT * FROM table_name;
