MySQL remove grant priv's from a drop user?

helptonewbie · 01-22-2008, 05:13 AM

Hi All,
I've dropped some users and database 'test' created on normal install of MySQL server 5.0.x

However as it says in the mysql doc that the grant priv's are not automatically removed is the best way to remove those priv's using the 'delete' syntax??

DELETE FROM mysql.db WHERE Db = 'test';

Is that the correct MySQL method, it doesn't seem overly clear if that is correct in the MySQL doc?

Cheers

Permissions are removed with revoke; delete removes rows from tables.

Yes but couldn't revoke these permissions as in a:-
select * from mysql.db;

i can see the tables test and test\_%, automatically created tables by MySQL with no users associated to them, in which case i couldn't remove it even though there wasn't a database called test anymore as i drop'd it. I've now used 'delete' to remove those from the table as its not something i need to use. Therefore not allowing anonymous users, and already default tables to be on the server.

Once you have dropped the test data base, you're done; however, if you want to get rid of the rest of it:

Code:

mysql mysql
drop database if exists test;
delete from db where db = 'test';
delete from db where db = 'test\\\%';
^D

will do that for you.

While you're digging around in there, put a password on the root user (the MySQL root user, not the system root) if you haven't already done that; then the syntax will be

Code:

mysql --password=password mysql
or
mysql -p mysql
password: <enter it>

cheers for that, i also used:
mysql's 'set password' and
delete from mysql.db where Db = test;

Thanks and regards

Bye the by... you may want to consider getting out of the habit of "...mysql.db..."

When you start MySQL, you can start "empty" or start with the name of the data base you want to use; e.g., an "empty" start is

Code:

mysql

and a "named" start is

Code:

mysql dbname

If you start empty, you select a data base to work with

Code:

mysql
> use dbname;

And, the less fiddling around you do with the mysql data base, the better (you can really mess things up if you manage to do something silly in that data base if you know what I mean -- been there, did that, don't wanna do dat again...).

Best of luck with it.
