Mysql user creation script

Question

I\'m trying to automate MySQL user creation procedure. I thought of creating a temp file that would contain mysql user creation statements, then I would have call it like this :

Answer 1

Just to answer why the error occurs and to show the differnce:

---

A) Expects @password to be a hash string ¹ value:

GRANT ALL PRIVILEGES 
    ON `mydb` . * TO 'username'@'localhost' IDENTIFIED 
BY
PASSWORD '@password';

^{Note the use of the PASSWORD keyword!}

---

B) Expects @password to be a clear-text string value:

GRANT ALL PRIVILEGES 
    ON `mydb` . * TO 'username'@'localhost' IDENTIFIED 
BY
'@password';

^{Note the missing PASSWORD keyword!}

---

¹ Where "hash string" is the result of SELECT PASSWORD('clearTextPasswd'); - see Snowman's answer for an example.
