procedure TForm1.Button1Click(Sender: TObject);
var
tSource, TDest: TTable;
begin
TSource := TTable.create(self);
with TSource do begin
DatabaseName := 'dbdemos';
TableName := 'customer.db';
open;
end;
TDest := TTable.create(self);
with TDest do begin
DatabaseName := 'dbdemos';
TableName := 'MyNewTbl.db';
FieldDefs.Assign(TSource.FieldDefs);
IndexDefs.Assign(TSource.IndexDefs);
CreateTable;
end;
TSource.close;
end;
