hi monalisa,

try to use an sql monitor to watch the real sql sent to server, and the
values of the parameters. There is a working example of such a monitor using
IBX components in http://codecentral.borland.com Look for author, Jeff
Overcash.
You have to include options to monitor in your IBDatabase component
