I need to create a function that will drop a field from a table, but I am having problem to create this function due to the kind of the field.

The error is when I try to compare whether the DataType is equal FieldExpected.

Function (Table, Field : String; FieldExpected: TFieldType) : Boolean
Var
  TQ : TADOQuery;
  I  : Integer;
  Drop : Boolean;
Begin
  TQ := TADOQuery.Create(Nil);
  TQ.Connection := Fmenu.ADOConnection1;
  Drop := False;

  Try
    With TQ do
    Begin
      Close;
      Sql.Add('SELECT * FROM ' + Table);
      Open;

      For I := 0 to Pred(TQ.Fields.Count) do
      Begin
        If TQ.Fields.Fields[I].FieldName = FieldThen
           Begin
             If Not TQ.Fields.Fields[I].DataType = FieldExpected Then
                Begin
                  Drop := True;
                End
             Else
                Begin
                  Drop := False;
                End
            Break
           End;
      End;

replace
             If Not TQ.Fields.Fields[I].DataType = FieldExpected Then
with
             If Not (TQ.Fields.Fields[I].DataType = FieldExpected) Then
