Calling a mysql query from linux or dos command line

There are times when you want to call a mysql command from the bash or dos script then call this script in a scheduler (cron job).
The example below will show you how to do so.

Explanation:
-u is where you put your username, you can either put a space or no space at all after the -u (both works). As you can see I prefer not to put any space.
-p is where you put your password.
-D is your database name. That’s a capital D.
-e this is where your query will go. It needs to be quoted (“). If it’s calling a stored procedure or stored function, you’ll need to use the CALL keyword, otherwise if it’s just a simple query don use the CALL keyword.
