This is about Firebird, but is equally applicable to InterBase: https://www.firebirdfaq.org/faq29/

InterBase does not support "AUTO_INCREMENT".

TStringHelper appeared in System.SysUtils in XE3. From beginning it had Split method.

What is the Delphi version ?

Please, show your code to query meta-data

Please show the code for one "procedure SetAsGuidArray(SourceItems: TArray<TGuid>); " as an example

How pp_lfopen is defined in header file ?

TStaticText ?

uses FireDAC.Phys.ODBCWrapper; procedure TForm252.Button1Click(Sender: TObject); begin ShowMessage(TODBCConnection(FDConnection1.CliObj).DRIVER_NAME); end; https://docwiki.embarcadero.com/Libraries/Athens/en/FireDAC.Comp.Client.TFDCustomConnection.CliObj

I attached the patch. If you will fail to apply it, then please go through support. fb5_ret.patch

@VLDG, thanks ! Yes, this is the issue in FireDAC support for Firebird 5. The issue is fixed, the changes will be included into Delphi 12 Update 1.

Please report this issue to quality.embarcadero.com, if it works now ... Or just post here: a minimal test project SQL script to create DB objects steps to reproduce the issue PS: this may be a changed FB 5 behavior or a regression bug (eg, https://github.com/FirebirdSQL/firebird/issues/7774)

The performance issue may be resolved by replacing: // around line # 4383 CurMonitorStatus := FThreadPool.FMonitorThreadStatus; if Signaled then Continue; with: CurMonitorStatus := FThreadPool.FMonitorThreadStatus; if Signaled then begin FThreadPool.FMonitorThreadWakeEvent.ResetEvent; Continue; end;

32bit FireDAC unit tests run without problems with libpq.dll v 9.5
