I need to using boolean delphi field for smallint interbase field; with 
a TIBBooleanField i can override TIBBooleanField.SetAsBoolean to set 
smallint value like:

procedure TIBBooleanField.SetAsBoolean(Value: Boolean);
var
   B: Smallint;
begin
   if Value then SmallInt(B):= 1 else SmallInt(B):= 0;
   SetData(@B);
end;

Here is my problem: True boolean value is stored in interbase Database 
as -1 and False as 0. But I've a large Database where boolean are stored 
through domain with 1 and 0 values.

How can I store boolean true value as 1 instead of -1?

Help is very appreciated!
