HI I would like to know how do you change the display label of a field in the grid if your TADOQuery SQL are both declared in the codes instead of using components.
looking at the example below, the genre will display as GENRE, product_type will be display as PRODUCT_TYPE in my grid. How do you change it? do i have to declare the stringfields or tfields? I don't know how to do it. Please help.THANKS!

procedure  TFrameProductBook.BitBtnCategoryLookUPClick(Sender: TObject);
var SQL :string;

begin
 SQL := 'select genre, category_id from category, product_type';
 SQL := SQL + ' where product_type = ''B''';
  SQL := SQL + ' order by :order';
  with FormCategoryLU do
  begin
  QryLU.SQL.text := SQL;

  QryLU.Open;

You can also rewrite

 SQL := 'select genre as caption, category_id from category, product_type';

Choose what is more convenient in a given circumstances.

Hi mkule,
Thanks for you reply. the first one didn't work for me :(
I know that you can manupulate the sql statement, but i wanna find out how to play with the field settings. the Tstringfileds and the Tfields in the columns of the Query because I would wanna make some of them invisible.

do you know any other way? Thanks

Hi Mokule,

I have this error.

SQL := 'select genre, category_id from category, product_type';
 SQL := SQL + ' where product_type = ''B''';
  SQL := SQL + ' order by :order';

I can write 'select genre as CAPTION but it would appear as CAPS.
If I tried 'select genre as ''Genre'' from category' it will return error.

Please help.
Thank you
ian

It should work.
One apostrophe was missed
What do you mean be don't work.

for i := 0 to DBGrid1.Columns.Count - 1 do
      begin
->>  if DBGrid1.Columns[i].FieldName = 'genre' then
          DBGrid1.Columns[i].Title.Caption := 'Caption genre';
      end;

stop program on this instruction in the loop and look what are Your Filed names
If they are CAPS rewrite as

  if DBGrid1.Columns[i].FieldName = 'GENRE' then
