AW: Manipulation eines Records in einer FDQuery

  Alt 15. Jun 2023, 12:32
Hallo Zusammen,

vielen Dank für Eure Gedanken. Wenn ich die Daten ohne Manipulation ziehe und an die Clients übergebe, funktioniert das wunderbar. Leider sind die Daten aber in der Datenbank nicht korrekt, worauf ich keinen Einfluss habe. Daher ist es erforderlich die korrekten Daten aus der anderen Datenbank zu holen.

Ich habe mal JOB_NAME in JOB_NAME1 umbenannt:
Delphi-Quellcode:
 MsQuery.SQL.Add('SELECT TOP 1 '+
                                'CASE WHEN ( '+
                                  'concat(rj.JOB_ID, ' + QuotedStr(' ') + ', JOB_NAME) is NULL) then '+
                                  'LAG(Concat(rj.JOB_ID, ' + QuotedStr(' ') + ', rj.JOB_NAME)) OVER (ORDER BY re.TIME_LOCAL DESC) ELSE '+
                                  'concat(rj.JOB_ID, ' + QuotedStr(' ') + ',rj.JOB_NAME) end AS JOB_NAME1, '+
                                'CONVERT( varchar( 10 ), re.Time_Local, 104 ) AS Datum, '+
Dann bekomme ich die gleiche Fehlermeldung beim Post.

Ich hatte ja auch schon getestet, ob die Fehlermeldung ausbleibt, wenn ich ein echtes Feld verwende (OPERATION_NAME). Aber das klappt auch nicht.

Wie gesagt, ohne die Manipulation klappt das wunderbar und derzeit nutze ich die Software auch so, aber es arbeiten manchmal die falschen Mitarbeiter gerade an den Maschinen.

Hat jemand eine Idee, warum mit dem Post ein Problem auftritt?

Vielleicht verwende ich die FDQuery falsch, denn diese habe ich ohne Felder angelegt, sondern lasse die mit dem Open anlegen...

Hier mal die ganze Procedure...
Delphi-Quellcode:
procedure TMxSQL.Get_act_MachineData(Machine_ID: string; LStream: TStream; RefreshData, SendData: boolean);
var Logic: TLogic;
      MsQuery: TFDQuery;

      Operationslist: string;
begin
   if (RefreshData = false) and (DB_Modul.Tmr_LM_RefreshData.Enabled = false) and (SendData = true) then begin
      RefreshData := true;
      DB_Modul.Tmr_LM_RefreshData.Enabled := true;
      DB_Modul.FLM_OfflineState := 0;
      DB_Modul.Write_LM_Protokoll('RefreshTimer aktiviert.');
   end;

   if (RefreshData = false) and (DB_Modul.Tmr_LM_RefreshData.Enabled = true) and (SendData = true) then begin
      DB_Modul.Tmr_LM_RefreshData.Enabled := true;
      DB_Modul.FLM_OfflineState := 0;
      DB_Modul.Write_LM_Protokoll('OfflineState-Counter zurückgesetzt.');
   end;
   if (DB_Modul.Tmr_LM_RefreshData.Enabled = false) then begin
      DB_Modul.Tmr_LM_RefreshData.Enabled := true;
      DB_Modul.FLM_OfflineState := 0;
      DB_Modul.Write_LM_Protokoll('RefreshTimer aktiviert. OfflineState-Counter zurückgesetzt.');
