PHP上的CQL2 / CQL3 Cassandra错误

While executing this code in PHP:

$db_nosql = new PDO('cassandra:host=127.0.0.1;port=9160;cqlversion=3.0.0');

I got a error message:

Fatal error: Uncaught exception 'PDOException' with message

'CQLSTATE[HY000] [2] Cannot execute/prepare CQL2 statement since the CQL has been set to CQL3(This might mean your client hasn't been upgraded correctly to use the new CQL3 methods introduced in Cassandra 1.2+).'

in /home/web/site/Test/page.php:202 Stack trace: #0 /home/web/site/Test/page.php(202): PDO->exec('USE mailing') #1 {main} thrown in /home/web/site/Test/page.php on line 202

I don't know what I am supposed to do in this situation. Does that means that the syntax is incorrect ?

Thank you.

dsjws44266 请再次阅读这可能意味着您的客户端未正确升级以使用Cassandra1.2+中引入的新CQL3方法

可以尝试。 它使用本机协议,不需要其他库。</ p>

原文

Can try the library. It uses the native protocol and does not require other libraries.
