We have just changed all of our DB functionality from the BDE with the standard component query to ADO with the ADOquery. The follow doesn’t work anymore now :

qRooms->Close();
qRooms->SQL->Clear();
qRooms->SQL->Add("Select * from Billeting where (SDATE >=:startdate and");
qRooms->SQL->Add("SDATE <=:enddate) or (EDATE >=:startdate and");
qRooms->SQL->Add("EDATE <=:enddate) or (SDATE <:startdate and");
qRooms->SQL->Add(" :startdate < EDATE) order by BLDG");
qRooms->Parameters->ParamByName("startdate")->Value = StrToDate(VOQDate);
qRooms->Parameters->ParamByName("enddate")->Value = (StrToDate(VOQDate) + 14);
qRooms->Open();

Why doesn’t this work? What am I doing wrong?
