The way I have the database set up, each record has 13 "fields", and I am surprised to find that when I do a SELECT to read them, I get a tuple with 13 things in it. This works fine, and has acted like a list up until I tried to change a field. We can use list(m) to make it into a list and then can change it -- but what will happen when we try to write it?
I was baffled as to why an UPDATE was not getting done. There was no error apparent, but the database was untouched. It turns out that a statement like this is required:
self.conn.commit ()Apparently any change to the database must be followed by a "commit" call. This requirement can by bypassed by setting a "autocommit" variable.
The data for an insert can be either a long tuple or a list, i.e. either of the following will work:
data = ( "test", "spam" )
data = [ "test", "spam" ]
sql = '''INSERT INTO projects(name,info) VALUES(?,?)'''
cur = conn.cursor ()
cur.execute ( sql, data )
conn.commit ()
