Is there a way to make a specific column in MySQL only allow INSERT, but not UPDATE or DELETE?

Question

For example, I have a table called stuff and it has a column called name .

I want my users to be able to INSERT into the name column, but not UPDATE or DELETE .

I know I can control this from the middle-tier business logic code, but is there some way to also prevent this at the MySQL database level for extra security?

I did see an old answer on SO about triggers but it's from 2013 and is probably out of date. I'm looking for a MySQL 8 answer.

A possible solution is to implement permissions on users or groups:

https://dev.mysql.com/doc/refman/8.0/en/grant.html#grant-column-privileges

GRANT SELECT (col1), INSERT (col1, col2) ON mydb.mytbl TO 'someuser'@'somehost';

So you your case it would be something like:

REVOKE ALL PRIVILEGES on mydb.stuff to 'userorgroup'@'somehost'

GRANT INSERT(name) ON mydb.stuff TO 'userorgroup'@'somehost'
