Why is GRANT not working in MySQL?

Question

I'm scratching my head on this one as I see a ton of helper websites showing how to create MySQL users and grant privileges but for some reason it just does not work for me. I tried on both WinXP and a MacBook Pro laptop with the latest MySQL version installed.

The following is just an example from when I worked with WordPress. The actual database is something different but same issues.

Here are the steps:

mysql> mysql -uroot -p<password>
mysql> CREATE DATABASE wwordpress;
mysql> CREATE USER 'www'@'localhost' IDENTIFIED BY 'basic';

Query OK, 0 rows affected (0.14 sec)

mysql> GRANT INSERT ON wordpress.* TO 'www'@'localhost' IDENTIFIED BY 'basic';

Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.03 sec)

mysql> SELECT * FROM mysql.user WHERE User='www' \G

*************************** 1. row ***************************
                 Host: localhost
                 User: www
             Password: *E85C94AF0F09C892339D31CF7570A970BCDC5805
          Select_priv: N
          Insert_priv: N
          Update_priv: N
          Delete_priv: N
          Create_priv: N
            Drop_priv: N
          Reload_priv: N
        Shutdown_priv: N
         Process_priv: N
            File_priv: N
           Grant_priv: N
      References_priv: N
           Index_priv: N
           Alter_priv: N
         Show_db_priv: N
           Super_priv: N
Create_tmp_table_priv: N
     Lock_tables_priv: N
         Execute_priv: N
      Repl_slave_priv: N
     Repl_client_priv: N
     Create_view_priv: N
       Show_view_priv: N
  Create_routine_priv: N
   Alter_routine_priv: N
     Create_user_priv: N
           Event_priv: N
         Trigger_priv: N
             ssl_type:
           ssl_cipher:
          x509_issuer:
         x509_subject:
        max_questions: 0
          max_updates: 0
      max_connections: 0
 max_user_connections: 0
1 row in set (0.00 sec)

mysql>

As you can see "Insert_priv: N" should be "Y".

Any suggestions?

Thanks in advance.

Answer 1

That's not where the most user GRANTed rights are stored - try

SHOW GRANTS FOR 'www'@'localhost'

to see database-specific permissions instead. (A grant would only show up in the user table if it was for all databases.)

Here's a (rather old) step-by-step detail of how permissions are stored in MySQL - I don't think things have changed much.

Answer 2

what you are selecting are the global privileges. you are however giving database (and host, but that doesnt matter) specific privileges.

GRANT INSERT ON wordpress.* TO 'www'@'localhost' IDENTIFIED BY 'basic';

theese permissions are stored in the db table.

just to point you in the right direction:

SHOW GRANTS FOR 'www'@'localhost'
