It is common practice to grant your application the privileges of “GRANT SELECT, INSERT, UPDATE, DELETE ON yourdb.* TO user@host”.
But what if you want to ensure you cannot DELETE data from just one table?
Ideally I want to be able to “REVOKE DELETE ON yourdb.important_table FROM user@host”. You cannot do currently this with the MySQL privilege system.
If your schema has 100 tables, and you want to remove DELETE from one, you have to define DELETE for the 99 others, and remember that for each new table, you need to remember to also modify user privileges.
