dynamically import

[Reid Lai]

Dear All,

How can I have a database connection depending on different DBI 2.0 
module dynamically?  What I want is like following:

a = "DBVendor"

if DBVendor == "PostgreSQL":
     from pyPgSQL import PgSQL
     connfactory = PgSQL
elsif DBVendor == "Oracle":
     from DCOracle2 import *
     connfactory = DCOracle2

conn = connfactory.connect(...)

I don't want to have endless if statement to determine DBVendor and know 
how to use ConfigParser.  But don't know how I can do at import 
statement.  Thanks for any help.
