Create a model for your table dynamically.

from django.db import models
from django.db.models.base import ModelBase

def create_model(db_table):

    class CustomMetaClass(ModelBase):
        def __new__(cls, name, bases, attrs):
            model = super(CustomMetaClass, cls).__new__(cls, name, bases, attrs)
            model._meta.db_table = db_table
            return model

    class CustomModel(models.Model):

        __metaclass__ = CustomMetaClass

        # define your fileds here
        srno = models.IntegerField(db_column='SRNO', primary_key=True)

    return CustomModel

and you can start querying the database.

In [6]: t = create_model('trial1')

In [7]: t._meta.db_table
Out[7]: 'trial1'

In [8]: t.objects.all()  # default db
Out[8]: [, '(remaining elements truncated)...']

In [9]: t.objects.using('test').all()  # test db
Out[9]: [, '(remaining elements truncated)...']
