SqlAlchemy equivalent of pyodbc connect string using FreeTDS

Question

The following works:

import pyodbc
pyodbc.connect(\'DRIVER={FreeTDS};Server=my.db.server;Database=mydb;UID=myuser;PWD=mypwd;TDS_Version=8.0;Port=1433;\')
         


        

Answer 1

The example by @Singletoned would not work for me with SQLAlchemy 0.7.2. From the SQLAlchemy docs for connecting to SQL Server:

If you require a connection string that is outside the options presented above, use the odbc_connect keyword to pass in a urlencoded connection string. What gets passed in will be urldecoded and passed directly.

So to make it work I used:

import urllib
quoted = urllib.quote_plus('DRIVER={FreeTDS};Server=my.db.server;Database=mydb;UID=myuser;PWD=mypwd;TDS_Version=8.0;Port=1433;')
sqlalchemy.create_engine('mssql+pyodbc:///?odbc_connect={}'.format(quoted))

This should apply to Sybase as well.

NOTE: In python 3 the urllib module has been split into parts and renamed. Thus, this line in python 2.7:

quoted = urllib.quote_plus

has to be changed to this line in python3:

quoted = urllib.parse.quote_plus
