You are trying to print to the console for development purposes? If you are showing a "None" as your result, then it appears your query isn't selecting any rows. If you use the command line interface to your DB (sqlite3?) can you form a SQL SELECT command that retrieves the records you want? If so, can you paste that command here? /dps -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
