with TQuery1 do begin
  SQL.Clear;
  SQL.Add('CREATE TABLE Table1 (');
  SQL.Add('AName varchar(10) NULL,');
  SQL.Add('Value int NULL');  // <- how to define it's default value?
  SQL.Add(')');
  ExecSQL;
end;

Thanks in advance!

?
a null must not defined, its a default,
if nothing oither is given

Create Table abc (
  AName CHAR(20) DEFAULT "X"
 ,Value INT DEFAULT 1
  )

not tested, just from head

I use the BDE replacement Opus Direct Access (www.opus.ch) for my Access work.  With that I can create/delete relations, set defaults, set anything I've ever wanted to be able to create or restructure.  And BTW, it's free and open-source.  I can provide examples.

Thanks mikepj, Opus DirectAccess is not bad, I have replaced the BDE by ODA. ;-)
