When I use dbi.OperationalError, I get this result:
Traceback (innermost last):
File "<pyshell#1>", line 1, in ?
collect.collect()
File "C:\PROGRA~1\Python\collect.py", line 50, in collect
except dbi.OperationalError:
AttributeError: OperationalError
Here is the printout of the dbi module:
['DATE', 'NUMBER', 'RAW', 'ROWID', 'STRING', 'TYPES', '__doc__', '__file__',
'__name__', 'dataError', 'dbDate', 'dbRaw', 'dbiDate', 'dbiRaw',
'integrityError', 'internalError', 'noError', 'opError', 'progError']
I am way out of my depth here. Any and all help is appreciated.
