MySQL : "The user specified as a definer ('root'@'%') does not exist"

I just found a problem about Mysql, and i found out solution.

If you've found following error while using mysql database:
     The user specified as a definer ('root'@'%') does not exist
Then you can solve it by using following :
     grant all on *.* to 'root'@'%' identified by 'password' with grant option;


i found it here... [link]
