| 89 | * @param callable $callback The callback that processes each chunk of rows. |
| 90 | * @param string $willDelete Set to true if you will make sure to delete all rows that were fetched. If you are in |
| 91 | * doubt and not sure if to set true or false, use "false". Setting it to true will |
