Hi,
what Database do you use? I use Firebird. There I search the generator value with a stored procedure, which I can execute from Delphis dbexpress component SQLStoredProcedure.

The code of the SP in Interbase or Firebird:
CREATE PROCEDURE NAMEOFYOURSP returns (
  NAMEOFYOURPARAM Integer)
AS
BEGIN
   NAMEOFYOURPARAM = GEN_ID(NAMEOFYOURGENERATOR,1);
END

In Delphi you create a SQLStoredProcedure component and connect it with your NAMEOFYOURSP. Then:
SQLStoredProcedure.ExecProc;
MyID:=SQLStoredProcedure.ParamByName('NAMEOFYOURPARAM').AsInteger;

Thats is.
