To connect to Amazon Redshift, you can use either a DSN or an ODBC connection string. Both of these methods use the connect function.

Connect to a DSN

To connect using a DSN:

cnxn = pyodbc.connect("DSN=CData Redshift Sys;User=MyUser;Password=MyPassword")

Provide a Driver Connection String

To connect using an ODBC connection string:

cnxn = pyodbc.connect("DRIVER={CData ODBC Driver for Amazon Redshift};User=admin;Password=admin;Database=dev;Server=examplecluster.my.us-west-2.redshift.amazonaws.com;Port=5439;")
