Php cassandra CQL中的获取数据问题
首先,我使用下面的查询创建了一个columnfamilyPhp cassandra CQL中的获取数据问题,php,codeigniter,cassandra,Php,Codeigniter,Cassandra,首先,我使用下面的查询创建了一个columnfamily CREATE TABLE gb_adminusers (au_id int,au_created_ip text,au_created_on text, au_email_address text,au_password text, au_status int, au_updated_on text,au_username text,PRIMARY KEY ((au_id)) ) WITH bloom_filt
CREATE TABLE gb_adminusers
(au_id int,au_created_ip text,au_created_on text, au_email_address text,au_password text,
au_status int, au_updated_on text,au_username text,PRIMARY KEY ((au_id))
) WITH bloom_filter_fp_chance=0.010000 AND caching='KEYS_ONLY' AND comment='' AND
dclocal_read_repair_chance=0.100000 AND gc_grace_seconds=864000 AND
index_interval=128 AND read_repair_chance=0.000000 AND replicate_on_write='true' AND
populate_io_cache_on_flush='false' AND default_time_to_live=0 AND
speculative_retry='99.0PERCENTILE' AND memtable_flush_period_in_ms=0 AND
compaction={'class': 'SizeTieredCompactionStrategy'} AND
compression={'sstable_compression': 'LZ4Compressor'};
然后成功插入下面两行
au_id | au_created_ip | au_created_on | au_email_address | au_password | au_status | au_updated_on | au_username-------+---------------+---------------------+--------------------+----------------------------------+-----------+---------------+------------

当我试图使用从表中获取结果时,我收到了以下警告
A PHP Error was encountered
Severity: Warning
Message: unpack(): Type N: not enough input, need 4, have 1
Filename: Cassandra/DataStream.php
Line Number: 66
A PHP Error was encountered

我的结果集如下所示:

如何解决此问题。我正在使用软件包。您能提供出错的代码吗?具体来说,第66行……下面我提到了第66行:返回重置(解包('N',$this->read(4));问题是当一列包含null时,它不会接受该列并产生错误。
