In SQLite, if you declare a column as INTEGER PRIMARY KEY and insert NULL into that column, a unique value will be automagically inserted in that column for you. The value may be the "next" unused value, or could also be a currently-unused value due to a "hole" in the sequence (perhaps because you deleted a record). If you need to guarantee that each new value is always the next in a continuous sequence,you can use INTEGER PRIMARY KEY AUTOINCREMENT instead of INTEGER PRIMARY KEY. Derrell
