Hi to all!
In the documentation of the PyGreSQL module it is said that a
pg.error exception is thrown when pg.connect or other pg functions cause an
error. How can i get the value of the error? I have tried print pg.error in
the except clause but i get only a _pg.error value...
For example:
try:
db = pg.connect( connection parameters);
except pg.error:
print pg.error;
This prints "_pg.error"...
Thanks in advance for your replies,
Denis

Try this:
try:
db = pg.connect(parameters)
except pg.error, error_message
print error_message
I tend to write the except statement a little
differently to remind me that the first parameter to
except is actually expecting a tuple. So instead I
generally write:
except (pg.error,), error_message
Yes, that looks ugly. But two months later I don't
have to look in the info file to see how to call
except.
I hope that is helpful,
Jason
