def _mytest_query(self, cr, uid, ids, name, args, context=None):
    print ('here is demo sql query function result ')
    cr.execute("""SELECT module,(id*5000)as result FROM ir_model_data WHERE id=1""")
    res = cr.dictfetchall()
    print ('here is demo sql query function result ')
    print (res)

def _invoiced_rate(self, cr, uid, ids, name, args, context):
    self._mytest_query(self, cr, uid, ids, name, args, context)
    amount_untaxed = 1
    record_id = ids[0]
    res = {record_id: 0.0}
    if amount_untaxed == 0:
        res[record_id] = 100.0
    else:
        res[record_id] = 50.0
    return res

_name = "checkroll.namelist.update"
_description = "This table is for keeping Name list updates"
_columns = {        
    'date': fields.date("Date"),

remove the self keyword in the paramater list.

What you done in your code for calling a function from function is totally wrong?

In python to call a function, we specify the function name with the round brackets, which you not specified.

Second need to pass argument as number of argument in function.

So you code must be like this:

def _invoiced_rate(self, cr, uid, ids, name, args, context):
        self._mytest_query(cr, uid, ids, name, args, context)
        amount_untaxed = 1
        record_id = ids[0]
        res = {record_id: 0.0}
        if amount_untaxed == 0:
            res[record_id] = 100.0
        else:
            res[record_id] = 50.0
        return res

And after complete function return statement is needed otherwise return None be default.

You can refere how to define function in python: http://docs.python.org/2/tutorial/controlflow.html#defining-functions

For openerp function you can get detail explanation here : http://doc.openerp.com/v6.1/developer/03_modules_2.html Under "Function Fields" Tag. Hope this help
