syntax error in FROM clause

hi,

i have a combo filled via ado's gettablenames
and onchange event of combo looks like:

procedure TForm1.ComboBox1Change(Sender: TObject);
begin
AdoTable1.Active := False;
AdoTable1.TableName := Combobox1.text;
DbMemo1.Datafield := Combobox1.Text + ' Code';
DbMemo2.Datafield := Combobox1.Text + ' Title';
AdoTable1.Active := True;
etc...


problem arises when a table name is stupid like
c++
 or
tablename with spaces
etc..

im getting a "syntax error in FROM clause" error .

i understand i could normally use quotes in a
sql statement to get around these sort of problems but
i dont know how to do it for this scenario ..is there a quick fix i can do for this?

as a last resort i can change the tablenames but id rather not ;-)

Regards Barry

just doublequote the tablename like "c++"

AdoTable1.TableName := '"'+Combobox1.text+'"';

hi meikl,
i tried that one first ;-)
it gives syntax error in query error.

but you lead me to right idea:

AdoTable1.TableName := '['+Combobox1.text+']';

i never tried that one i was trying using "" and ()..

cheers Barry

while im here another piece of code looks like :

  AdoQuery1.SQL.Clear;
  AdoQuery1.SQL.Add
  ('SELECT * FROM '+combobox1.text+' WHERE '+Edit1.Text+' IN '+combobox1.text+'.['+combobox1.text + ' Code]');
  AdoTable1.DisableControls;
  edit1.text := AdoQuery1.SQL.Text;
   Adoquery1.ExecSQL;
  ADOTable1.EnableControls;

a bit messy i know but the sql ends up as:

SELECT * FROM Application WHERE shell IN Application.[Application Code]

which produces the following exact error:

in operator without () in query expression
 'shell IN Application.[Application Code]'

do you know what the sql should end up like for that to work?

i did have it working on simple tablenames but again when i came to a table with a break in name etc it died so i had to start the []()"" stuff :-)

just to clarify the [] did work to solve original problem:

AdoTable1.TableName := '['+Combobox1.text+']';
