user permissions

[Ясен Вилиев]

Here is the case.
I have mysql user which has from server privileges only RELOAD.
This user has access only to one database.
This user has granted with all the permissions to this specific database.
After some time, I decided to revoke INSERT privilege from only one specific table.

It was not possible, because mysql could't find INSERT to be granted to this table.
I decided to try to redeclare privileges by granting all permission except INSERT to this specific table. But without luck. I was still able to insert rows.

So is there a intelligent way to redeclare already inherited privileges on database level for specific table?

Or I have to revoke all privileges on database level first and then grant for every single table what I want?
