Dear Alan,
I have read your web page and try to test thing out on SQLite.
Attached is my code:
import sqlite3
conn = sqlite3.connect('example1.db')
c = conn.cursor()
c.execute('drop table if exists stocks')
c.execute('''CREATE TABLE stocks
(code text)''')
# Insert a row of data

Hi,
I have a dictionary with keys as employee badges and values as their names.
Both key and value are strings.
I want to read the badges from a sql select and use that to look up the
names in the dictionary. But since the result is a tuple, it doesnt' work.
how can i overcome this?

I think you are missing the fetch call. The cursor only executed your
query, but hasn't fetched any thing out.
