Doing it the way you show, with a CONSTRAINT clause, won't do the trick. Make it CREATE TABLE IF NOT EXISTS Lists ( wID integer, ltitle text, llink text, units text, date text, ListsID integer primary key, new integer); Scott Baker already addressed the rest of your problem.

Just add NULL for the primary key value. SQLite will autopopulate the
number, but you have to tell it to do it. Just because it's a primary key
doesn't mean you can't ALSO provide it a value (like 73). So you have to
tell it to pick one itself by using NULL.

[sqlite] Problem with inserting and integer primary key
So, I create a table as follows:
CREATE TABLE IF NOT EXISTS Lists (
wID integer,
ltitle text,
llink text,
units text,
date text,
ListsID integer,
new integer
, CONSTRAINT Lists_pk PRIMARY KEY (ListsID))
To insert data I do (this is in Python):
x = dcur.execute('insert into Lists values (?, ?, ?, ?, ?, ?)', (123,
'YouTube Videos', 'http://www.youtube.com', 'views', '10/14/08', 4))
And I get:
OperationalError: table Lists has 7 columns but 6 values were supplied
I only supplied 6 values because, according to the sqlite documentation:
"If a table contains a column of type INTEGER PRIMARY KEY, then that column
becomes an alias for the ROWID. You can then access the ROWID using any of
four different names, the original three names described above or the name
given to the INTEGER PRIMARY KEY column. All these names are aliases for one
another and work equally well in any context.
"When a new row is inserted into an SQLite table, the ROWID can either be
specified as part of the INSERT statement or it can be assigned
automatically by the database engine."
So, if I want the engine to automatically assign the ROWID, do I have to
specify the PK column or not? If the former, how do I get the table to
automatically assign the ROWID? Thanks.
