I´d write these sentences in Delphi.

name_of_IBStoredProc.ParmByName('Param1').AsString....
name_of_IBStoredProc.ParmByName('Param2').AsString....
name_of_IBStoredProc.Prepare;
name_of_IBStoredProc.ExecProc;

But...

When it´ll post in my Database?

If I´m open ith another software like IBExpert in the same time, I see that
the records does´t appear until I close MyApplication.

I need post all the records so soon, what can I do in myApplication?

Regards...
