Hi,

Import the DAO type library (DAO_TLB.PAS), add it to your uses list then paste the following code.

var
  FEngine, FDB : OleVariant;
begin
  FEngine := CoDBEngine.Create;
  FDB := FEngine.OpenDatabase('c:\db1.mdb');
  FDB.TableDefs['Table1'].Name := 'NewName';
  FDB.Close;
  FDB := Unassigned;
  FEngine := Unassigned;
end;

Or without type libraryes... just do it the natural way... create a new table with the new name with the same field structure and then insert into newtable select * from oldtable... Something like this:

AdoQuery1.Active:=false;
 AdoQuery1.SQL.Clear;
 AdoQuery1.SQL.Add('create table NewTABLE (FirstField varchar(30),SecondField varchar(20), 3rdField int)';//Keep the same structure as in the old table
 AdoQuery1.ExecSQL;

 AdoQuery1.Active:=false;
 AdoQuery1.Sql.Clear;
 AdoQuery1.SQL.Add('insert into NewTABLE Select * from OldTABLE); // copy the contents of old table in the new one
 AdoQuery1.ExecSQL;

 AdoQuery1.Active:=false;
 AdoQuery1.Sql.Clear;
 AdoQuery1.SQL.Text:= 'drop table OldTABLE'; //delete the old table
 AdoQuery1.ExecSQL;


And there you go...
