I just tried this statement:
==========================================
cursor.execute( '''INSERT INTO counters(page, hits) VALUES(%s, %s) RETURNING
(pin)
ON DUPLICATE
KEY UPDATE hits = hits + 1''', (htmlpage, 1) )
except MySQLdb.Error, e:
print ( "Query Error: ", sys.exc_info()[1].excepinfo()[2] )
==========================================
and the error python tells me is:
<type 'exceptions.AttributeError'>: 'ProgrammingError' object has no attribute
'excepinfo'
args = ("'ProgrammingError' object has no attribute 'excepinfo'",)
message = "'ProgrammingError' object has no attribute 'excepinfo'"
