yep, use the username and pass you made when starting the winmsqladmin
GRANT ALL PRIVILEGES ON *.* TO Username@localhost IDENTIFIED BY 'Password' WITH GRANT OPTION;
change the username to the username your using, likely root, then set the password to what ever you want the pass to be
this changes the permissions to allow the user to use any database, if you wanted to just do one database for example, change the *.* to dbname.* (database name . and * for all tables etc in that database)
execute this command using the mysql -u [username] -p[passsword]
just with the -p and it will prompt for the password if one is set
forexample:
c:\mysql\bin\mysql -u root -ppassword
(notice no space between the -p and the password)
dont forget to change databases before sourcing, example:
use eq;
hope that helps some
