you can use this code

- (void)viewDidLoad {

self.navigationItem.rightBarButtonItem = self.editButtonItem;

}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
        ;

    if (editingStyle == UITableViewCellEditingStyleDelete) {
        // Delete the row from the data source
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:YES];
    }   

        }

Here's a good tutorial of sqlite: http://www.icodeblog.com/2008/08/19/iphone-programming-tutorial-creating-a-todo-list-using-sqlite-part-1/

you'll use sqlite3_prepare_v2 but I know there are some helper frameworks out there that people will recommend (I haven't used them so can't comment)
