An mysql-python tutorial?

Hi.

Been told by the admin of my (free!) server that he'd rather I should
learn to use mysql if I want to continue writing cgi scripts there.

Not even sure exactly what mysql is.

Is there a simple tutorial anywhere on the web about using python + mysql?

Did you try googling?

There are two items in the very first page that should be of use to you.
One is the Python-MySQL module, which you should have installed.

http://sourceforge.net/projects/mysql-python

There is an examples directory that has some concrete stuff to help you
learn.

Another hit is a basic tutorial, simple to follow and learn :-
http://images.devshed.com/Server_Sid...ythonMySQL.pdf

And here is one more site, good stuff here too:-
http://www.kitebird.com/articles/pydbapi.html

You might also want to check the "Charming Python" pages at IBM.com but
I dont know if they have articles covering mysql.

HTH!

Thanks,

It's a pretty good tutorial, thought I would recommend you forget about
the fetchone() example. The example below demonstrates three additional
features that will make your life easier: MySQL option files, tuple
unpacking, and cursors as iterators (fourth feature: the default host
is localhost; this is rapidly turning into the Spanish Inquisition
sketch):

#!/usr/bin/python
import MySQLdb
db = MySQLdb.connect (db="db56a", read_default_fi le="~/.my.cnf")
cursor = db.cursor()
cursor.execute( "SELECT name, species FROM animals")
for name, species in cursor:
print name, "-->", species

(I also shy away from doing SELECT *; what if your schema changes?)
(If the indentation is hosed, blame Google Groups.)

Hi.

I followed the instructions there, tried out the test script they
recommend.

Can you tell me why this command, in the python interpreter:
conn = MySQLdb.connect (host = "localhost" , user = "flipper", passwd =

"[hidden]", db = "mydb")

produces this error:
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.3/site-packages/MySQLdb/__init__.py", line 63, in Connect
return apply(Connectio n, args, kwargs)
File "/usr/lib/python2.3/site-packages/MySQLdb/connections.py" , line 115, in __init__
self._make_conn ection(args, kwargs2)
File "/usr/lib/python2.3/site-packages/MySQLdb/connections.py" , line 41, in _make_connectio n
apply(super(Con nectionBase, self).__init__, args, kwargs)
_mysql_exceptio ns.OperationalE rror: (1045, "Access denied for user:
'flipper@localh ost' (Using password: YES)")

I also have MySQL installed, and tried setting up the user flipper with
the mysql client, as per the instructions here:

It definitely looks like an access control problem; recheck your grants.
