Required python modules: MySQLdb

salt.modules.mysql.connect(**kwargs)

wrap authentication credentials here

returns: {'query time': {'human': '39.0ms', 'raw': '0.03899'},
'rows affected': 1L}

salt '*' mysql.query mydb "SELECT id,name,cash from users limit 3"

Run a query on "mydb" and use row 0, column 0's data.
{{ salt['mysql.query']("mydb","SELECT info from mytable limit 1")['results'][0][0] }}

salt.modules.mysql.slave_lag()
