Python Pyodbc Example
exception when connecting to database and have no connection, but I always freeze at pyodbc.connect(connstr). I tried all errors from documentation, tried just "except Exception" but I see my program just freeze when cannot connect to database and don't check except section. (Freeze is caused by my on-purpose disconnection from database and program just does nothing (windows "no answer") until my hard reset): import pyodbc connstr=('DRIVER={SQL Server Native Client 11.0};Server="server_ip";port=1433;Network Library=DBMSSOCN;Database="name";uid="uid";pwd="pwd";') try: pyodbc execute stored procedure print("I'm here - no problem") conn=pyodbc.connect(connstr) print("of course not here") except ...no_matter_what_I_write_here... : print("but never there too") python python-3.x exception pyodbc share|improve this question edited Dec 15 '15 at 21:49 Jonathan Leffler 441k62513824 asked Dec 15 '15 at 20:46 mpruchni 144 is the freeze caused by a long timeout? Please show the output... –Mauro BBianc-Pynchia Dec 15 '15 at 20:50 There is no output, no errors, nothing –mpruchni Dec 15 '15 at 20:55 ok, then check the documentation of pyodbc.connect to see what the behaviour is in case of error and if there are any parameters/global cfg you can set to change the timeout limit –Mauro BBianc-Pynchia Dec 15 '15 at 21:19 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote Assuming you are not connecting on thread. Coz Signals will not work in non main thread. import signal from contextlib import contextmanager class TimeoutError(Exception): pass @contextmanager def time_limit(seconds): def signal_handler(signum, frame): raise TimeoutError("Time out") signal.signal(signal.SIGALRM, signal_handler) signal.alarm(seconds) try: yield finally: signal.alarm(0) try: with time_limit(10): conn=pyodbc.connect(connstr) except TimeoutError as e: print "couldn't connect for long time" share|improve this answer edited Dec 15 '15 at 21:54 answered Dec 15 '15 at 21:40 Nikhil Rupanawar 82231738 add a comment| up vote 0 down vote accep

The exception classes specified in the Python DB API specification are used: Error DatabaseError DataError OperationalError IntegrityError InternalError ProgrammingError NotSupportedError When an error occurs, the type of exception raised is based on the SQLSTATE value, typically provided by the database. SQLSTATE Exception 0A000 pyodbc.NotSupportedError 40002 pyodbc.IntegrityError 22*** pyodbc.DataError 23*** pyodbc.IntegrityError 24*** pyodbc.ProgrammingError 25*** pyodbc.ProgrammingError 42*** pyodbc.ProgrammingError HYT00 pyodbc.OperationalError HYT01 pyodbc.OperationalError For example, a primary key error (attempting to insert a value when the key already exists) will raise an IntegrityError.
