hello,
I need to execute sql query from command line

I have to schedule a batch file which execute a query onto a mysql DB (so specifying username, pwd, sql file, server etc...) and get the results into a xls (or csv or other) file....

may you help me?

thanks

Use the MySQL commandline program and pass the script to be executed:
