I am sure this is what I want:
http://www.python.org/topics/database/docs.html
"The documentation for the PythonWin ODBC module."
but it is 404.
google isn't being nice.
Anyone know where I can find some simple examples?
I have used odbc in other environments, so just need to know what modules, and
the lines to connect and execute a sql command.
Here's a very simple example for mxODBC:
# mxODBC is available from
http://www.egenix.com/products/python/mxODBC/:
# On Windows:
from mx.ODBC import Windows as Database
# On Mac OS X:
from mx.ODBC import iODBC as Database
# On Linux/BSD/etc.:
from mx.ODBC import unixODBC as Database
# or
from mx.ODBC import iODBC as Database
# Open a connection to the database
connection = Database.DriverConnect('DSN=<datasourcename>;'
'UID=<username>;'
'PWD=<password>;'
'KEYWORD=<value>')
# replace the values accordingly, add new keyword-value pairs as
# necessary for your data source; data sources are configured
# in the ODBC manager
# Create a cursor; this is used to execute commands
cursor = connection.cursor()
# Create a table
cursor.execute('CREATE TABLE mxodbcexample1 '
' (id integer, name varchar(10), data varchar(254))')
# this command does not create a result set, so there's nothing
# to fetch from the database; however in order to make the
# change permanent, we need to commit the change
connection.commit()
# Prepare some data rows to add to the table, ie. a list of tuples
rows = []
for i in range(42):
name = 'name-%i' % i
data = 'value-%i' % i
rows.append((i, name, data))
# Add the data in one go; the values from the tuples get assigned
# to the ?-mark parameter markers in the SQL statement based on
# their position and the SQL statement is executed once for
# each tuple in the list of rows
cursor.executemany('INSERT INTO mxodbcexample1 VALUES (?,?,?)',
rows)
# If you apply changes to the database, be sure to commit or
# rollback your changes; a call to .commit() or .rollback()
# will implicitly start a new transaction
connection.commit()
# Now fetch some data rows
from_id = 40
to_id = 42
cursor.execute('SELECT * FROM mxodbcexample1'
' WHERE (id >= ?) and (id < ?)',
(from_id, to_id))
# Fetch the results
for i, row in enumerate(cursor.fetchall()):
print 'Row %i: %r' % (i, row)
# Remove the table again
cursor.execute('DROP TABLE mxodbcexample1')
connection.commit()
# Close the connection
connection.close()
With MS Access this gives:
Row 0: (40, 'name-40', 'value-40')
Row 1: (41, 'name-41', 'value-41')
