I am trying to convert an app from using BDE to ADO. I've run into a
parameter problem I don't understand. I get an error that says: ADOqHistory:
Parameter 'HistoryDay' not found.
Here is the code:
ADOqHistory->Close();
ADOqHistory->SQL->Clear();
ADOqHistory->SQL->Add("set identity_insert HistorySchedule on");
ADOqHistory->SQL->Add("insert into historyschedule
(uid,MDay,CF,Background,Tag1,Tag2,Tag3,Tag4)");
ADOqHistory->SQL->Add("select * from schedule where MDay < :HistoryDay");
ADOqHistory->SQL->Add("set identity_insert HistorySchedule off");
ADOqHistory->Parameters->ParamByName("HistoryDay")->Value = HistoryDate;
ADOqHistory->Prepared = true;
ADOqHistory->ExecSQL();

What am I doing wrong?

Thanks
