Access Denied for User ODBC @ localhost

Question

i have installed Mysql on Windows7, i used mysql with mysql command line client & i also use Mysqldump in windows cmd, & it was working without any problem. But today, i tried to export database using mysqldump with this command in cmd

mysqldump –u root -p mypassword db_name > f:\mydb.sql

i tried many other commands and i always see error

Access Denied for User 'ODBC'@'localhost' (using password: yes) when trying to connect

as you can see, in mysqldump command i am using root as user then why i get user ODBC error ? one more thing, using mysql command line client i am still using mysql normally without any problem using root as user. i also tried to login in cmd with this command

mysql –u root -p mypassword

but still same error. and my password is 100% correct. kindly tell me how to solve this problem. Thanks

Answer 1

Have you tried storing pass in the cfg file? http://dev.mysql.com/doc/refman/5.7/en/password-security-user.html

Answer 2

try from command line:

 mysql -u root -p 

and then, when you are being asked for password, just type it.
Try the same with mysqldump command without typing your password after -p.
