depending on your database and your privileges
you can place the ddl-statment in a query and use the execSQL-method

No one said in comments that you are beginner ;-)

anyway, as me and meikl told you, any query component will work, also I prefer to use AdoCommand with ado for DLL statement, for example to create database just do

   cmd1.CommandText := 'create database SqlDB';
   cmd1.Execute;

and you can do any other DLL as the same way,

BTW, the adoCommand above attached to connection which connect to sql server without specifing a database

Hi,

It's also easy :-)

here's two buttons, one will deattach the database and the other to reattach it again

procedure TForm8.btnDeattachDBClick(Sender: TObject);
begin
  cmd1.CommandText :='sp_detach_db "pubs"';
  cmd1.Execute;
end;

procedure TForm8.btnAttachDBClick(Sender: TObject);
begin
  cmd1.CommandText :='sp_attach_single_file_db @dbname = "pubs", ' +
          ' @physname = "C:\Program Files\Microsoft SQL Server\MSSQL\Data\pubs.mdf"';
  cmd1.Execute;
end;

Regards,
Mohammed
