This example is the same as the previous example but it operates on a 'captcha protected' table named 'TABLE1_CAPTCHA'. Captcha protection is necessary if you allow inserts to be made on public websites. NextDB provides simple utilities for adding captcha protection to tables. Tables that are captcha protected require a text field named 'captcha' which expresses the human readable text of the nextdb captcha image retrieved by net.nextdb.Util.getCaptchaURL();
