printf ( "Error facility: %d\nError code: %d\nError msg: %s\n" , cubrid_error_code_facility (), cubrid_error_code (), cubrid_error_msg ());
cubrid_disconnect ( $conn );
exit;
}

cubrid_bind ( $req , 2 , $name_list [ $i ]);
cubrid_bind ( $req , 3 , $city_list [ $i ]);

cubrid_rollback ( $conn );
} else {
cubrid_commit ( $conn );
$req = cubrid_execute ( $conn , "SELECT * FROM publishers" );
while ( $result = cubrid_fetch_assoc ( $req )) {
printf ( "%-3s %-20s %-15s %-3s %-15s\n" ,
$result [ "pub_id" ], $result [ "pub_name" ], $result [ "city" ], $result [ "state" ], $result [ "country" ]);
}
}
cubrid_disconnect ( $conn );
