I have a hard time to abort transaction
I'm using Access 97

$connection_id=odbc_connection("DSN","","",);
$result=odbc_exec($connection_id, "Select * from table");
odbc_result_all($connection_id);
//prints 5 rows

$result=odbc_exec($connection_id, "Delete * from table where ID=1");
$ suc=odbc_rollback($connection_id);
echo "$suc";
//prints 1 it means rollback succed

$result=odbc_exec($connection_id, "Select * from table");
//prints 4 rows
