      Hi Danke
      ich bekomme aber immer diese Fehlermeldung"lastError":

      [Microsoft][ODBC-Treiber für Microsoft Access] 27 Parameter wurden erwartet,
      aber es wurden zu wenig Parameter übergeben. QODBC3: Unable to execute statement

      Ich weiss es nicht welche Parameter fehlt.
      Sieht es überhaupt einen Update statement so aus "Wie oben "

      danke

        @Galilio Yes the update statement works in that way. AFAIK it is not compulsory to update all columns when using update query. Does your table contain 27 columns ?

            @Galilio Something strange. The table contains 28 columns, the error shows 27 are expected and you are actually updating 25 which is fine. Are you sure you are looking for correct table ?
            Also can you try updating just 1 column ?

              Wie kann ich den query lesen bevor exec()
              z.B:

              QSqlQuery query;
              query.prepare("........");
              query.bindvalue(.....);
              ....
              //und genau hier bevor es "query.exec();" durchgeführt wird, der Inhalt von query lesen.
              query.exec();
              

              Danke

                @Galilio
                NACH dem exec() aufruf kannst du QSqlQuery::executedQuery() verwenden
                Oder siehe hier.
