Create a trigger that prevents updating all rows in a table
Posted by: david lee

I'm new to triggers, and still a new web developer.

I have an "Emails" table and there is a bug that sets the 'sent_at' column to today's date for all the rows (and there are over a million rows)
This happens every few months or so and it's a pain in the ass to fix.

Is there a trigger I can write that will prevent my "Emails" table from updating all the rows? It can be done in SQL server, but I haven't found anything in mysql.
