var
Conn : TOracleConnection;
Tran : TSQLTransaction;
Q : TSQLQuery;
begin
Try
try
Conn := TOracleConnection.Create(nil);
Tran := TSQLTransaction.Create(nil);
Q := TSQLQuery.Create(nil);
Conn.HostName := ''; //my ip, user, password and databasename.
Conn.UserName := '';
Conn.Password := '';
Conn.DatabaseName := '';
Conn.Connected := True;
Conn.Transaction := Tran;
Q.DataBase := Conn;
Conn.Open;
Tran.Active := true;
Q.SQL.Text := 'SELECT * From EditionView_SPR';
Q.Open;
Q.First;
while not (Q.EOF) do
begin
Memo1.Lines.Add('x');
Q.Next;
end;
Q.Close;

Q.Free;
Tran.Free;
Conn.Free;
end;
