Thanks for opening the issue.
Can you tell me what data types you have inserted and also what data was inserted so I can write a regression test and patch?

Hi yeh there is no data at all. It is empty and the structure is

It's true, that there are issues with empty fields. Check #33 as well.
I'm gonna check for your case what is going on.

I'm getting the same error, with a very simple query:

$data = $database->query('SELECT * FROM "client" WHERE "id" = :id', ['id' => 'a5b9491e-372d-49d9-943c-63d40dcb67f4']);

I am getting the data I need, but I get this warning:

Warning: unpack(): Type l: not enough input, need 4, have 1 in /var/www/cassa/vendor/evseevnn/php-cassandra-binary/src/Protocol/Response/DataStream.php on line 77

I've found the cause of this issue. It is introduced in 6f1cae9

Please revert this patch. Until then I have to rely on:

    "require": {
        "evseevnn/php-cassandra-binary": "dev-master#31fa28eb756e5d06470a1e4ae4698d44250231b8"
