This sounds very strange to me why you want to do what you are asking, I
would relook at the keys I have created in the table and change them or
remove them completely (but I probably may not understand your question
fully).  The other way is to use the Locate function of the table and only
append records that are not located

if(!Table1->Locate("KeyField","New Value",TLocateOptions()))
    {
      Table1->Append()  //or Table1->Insert();
      Table1->FieldByName("KeyField")="New Value";
      Table1->Post();
    }
