当我尝试使用以下代码时,它无法正常工作.

require_once('PHPcassa/connection.PHP');
 require_once "PHPcassa/columnfamily.PHP";

 // Create new ConnectionPool like you normally would
 $pool = new ConnectionPool("newtest");

 // Retrieve a raw connection from the ConnectionPool
 $raw = $pool->get();

 $rows = $raw->client->execute_cql_query("SELECT * FROM User WHERE KEY='PHPqa'",cassandra_Compression::NONE);

 echo "<pre>";
 print_r($rows);
 echo "<pre>";

// Return the connection to the pool so it may be used by other callers. Otherwise,// the connection will be unavailable for use.
$pool->return_connection($raw);
unset($raw);

它没有返回,我也尝试过以下查询

$rows = $raw->client->execute_cql_query("SELECT * FROM User WHERE age='32'",cassandra_Compression::NONE);
$rows = $raw->client->execute_cql_query("SELECT * FROM User WHERE name='jack'",cassandra_Compression::NONE);

但是当我尝试的时候

$rows = $raw->client->execute_cql_query("SELECT * FROM User",cassandra_Compression::NONE);

给出正确答案,显示所有行.请告诉我,如何正确使用’WHERE’.
