Ramin:

Hi,

i going to connect of SQLAlchemy to other mssql instance exm: `<ip>\SQLInstance` but i see your [docs](http://docs.sqlalchemy.org/en/latest/dialects/mssql.html#module-sqlalchemy.dialects.mssql.pymssql) SQAlchemy default connect to `.`  instance, 

default instance code :
```python
from sqlalchemy import create_engine
engine = create_engine('mssql+pymssql://<user>:<pass>@<ip>:1433/database_name')

from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base()
from sqlalchemy import Column, Integer, String

class teeetttt(Base):
     __tablename__ = 'testtetetet'
     id = Column(Integer, primary_key=True)
     name = Column(String)
     fullname = Column(String)
     password = Column(String)

     

print teeetttt.__table__
ed_user = teeetttt(name='ed', fullname='Ed Jones', password='edspassword')
from sqlalchemy.orm import sessionmaker
Session = sessionmaker(bind=engine)
Session = sessionmaker()
Session.configure(bind=engine)
session = Session()
session.add(ed_user)
session.commit()
print ed_user.name
session.query(teeetttt).all()
f  = session.query(teeetttt).all()
print f[0].name
print session.query(teeetttt).all()

```

my goals connect to ```engine=create_engine('mssql+adodbapi://sa:a`123456@172.16.20.181:1433\SQLInstance/DB')``` that `SQLInstance` this is my instance and DB is database name
