I am using python to collect data and insert it into postgresql. I am hoping there will be someone on this list that has used python for this becuase all the books and documentation on the subject seem sparse. I am using pgdb. I know psycpg is also a DBI compliant interface for postgresql. If there is a recommendation as to which one is better, I'd like to hear it. (better for me now means that it has better documentation, sample code, etc.) I am constructing a sql insert statement (parameterized) and would like to catch meaningfull exceptions like, keyviolation (on the insert) or other postgresql exceptions that might happen. So far the only exception I see from pgdb when I do a full traceback and anlyze that. What I would like is something like try: cursor.execute(sql, parameters) except KeyViolation: except DataConversionError: and such like. I would really appreciate any pointers you might have on using python with postgresql. thanks. -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"
