This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

Python and SQL / the DB API and Gadfly

Posted by admin (Graham Ellis), 13 April 2004
Python supports connections to numerous SQL databases - have a look at the Special Interests Group section on http://www.python.org to find out about the Python DB API.

Gadfly is a pure Python SQL database handler that's great for learning and small tasks ... I've been sorting out the "wood from the trees" today and have two short example programs - one of which initialised Gadfly and sets up tables, the other which looks at the data storded via a select command:

Code:
import sys
import gadfly

conn = gadfly.gadfly()
conn.startup("demo","datadir")

th = conn.cursor()
th.execute("Create table people (id integer, name varchar)");

th.execute("Insert into people(id, name) values (1,'Graham')");
th.execute("Insert into people(id, name) values (2,'Lisa')");
th.execute("Insert into people(id, name) values (3,'Charlie')");
conn.commit()


and

Code:
import sys
import gadfly

conn = gadfly.gadfly("demo","datadir")

th = conn.cursor()

th.execute("select * from people")
for x in th.fetchall():
    print x
