خطای کامند لاین در اتصال

mysql : The term 'mysql' is not recognized as the name of a cmdlet, function, script file, or operable program. Check 
the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ mysql -h localhost -u root -p
+ ~~~~~
   + CategoryInfo          : ObjectNotFound: (mysql:String) [], CommandNotFoundException
   + FullyQualifiedErrorId : CommandNotFoundException

بعد از زدن خط کد مربوط به اتصال به دیتابیس این خطا را میبینم لازم به ذکر است که mysql زمپ روشن است و حتی powershell را run as adminstrator هم کردم ولی درست نشد
