scripts/mysql_fix_privilege_tables.sql

--- This scripts updates the mysql.user, mysql.db, mysql.host and the
--- mysql.func tables to MySQL 3.22.14 and above.
+-- This script converts any old privilege tables to privilege tables suitable
+-- for MySQL 4.0.
 
--- This is needed if you want to use the new GRANT functions,
--- CREATE AGGREGATE FUNCTION or want to use the more secure passwords in 3.23
+-- You can safely ignore all 'Duplicate column' and 'Unknown column' errors"
+-- as this just means that your tables where already up to date.
+-- This script is safe to run even if your tables are already up to date!
 
--- If you get 'Access denied' errors, you should run this script again
--- and give the MySQL root user password as an argument!
+-- On unix, you should use the mysql_fix_privilege_tables script to execute
+-- this sql script.
+-- On windows you should do 'mysql --force < mysql_fix_privilege_tables.sql'
