subprocess & isql

[peterff66]

Hello Python community, 

I am working on a project that retrieves data from remote Sybase. I have to use isql and subprocess to do this. Is the following correct?

1. call subprocess.popn to run isql, connect to Sybase
2. run sql ("select ...from ...")
3. write retrieved data to subprocess.pipe
4. retrieve data from pipe

Did anybody do similar work before? Any ideas (or code piece) to share?

Thanks so much.
