Iron Python DSL for DB Update II


Attepting releasing early & often - here are a few new features to the ideas I'm putting together for the Database specific DSL.  I'll summarize all that's possible with it now with the new stuff highlighted in red.

#some connection strings
cn = "Data Source=.\\sqlexpress;Initial Catalog=MVCBaby;Integrated Security=SSPI;"
cn2 = "Data Source=.\\sqlexpress;Initial Catalog=Irvine;Integrated Security=SSPI;"

#some things to do

The overall idea is to build a language centric, developer oriented implementation of what is done in a tool like SSIS or its predecessor DTS - I'm using SQL Server for a start but there's no reason this can't include other database platforms. It's quite exciting that even without knowing much Python I can get that much done in the language.  I'll spend time refactoring and reorganizing the script I've started with, but please feel free to download and modify it. Please post any improvements or ideas for how I can improve the Python and added any other features to the dsl. (Point on using __getattr__ well taken).

My todo list?
1. Aforementioned "transforms" for data in migration
2. Exception handling :^)
3. Copying tables is a rough sketch but needs a lot of work
4. Export formats besides CSV and XML: arbitrary delimiters and fixed field length
5. __getattr__ :^)
