卡桑德拉未定义的名称在where子句

Question

我查询卡桑德拉表执行以下命令： select * from oap.purchase_events where clientNumber = '100'

表包含与clientNumber 100行，但是我得到这个错误：

InvalidRequest：代码= 2200 [查询无效]消息= “未定义名称clientnumber在where子句（ 'clientnumber = 100'）”

表定义：

CREATE TABLE oap.purchase_events (
    "parentId" text, 
    "childId" text, 
    "clientNumber" text, 
    cost double, 
    description text, 
    "eventDate" timestamp, 
    "logDate" timestamp, 
    message text, 
    "operationalChannel" text, 
    "productDuration" bigint, 
    "productId" text, 
    "transactionId" text, 
    volume double, 
    "volumeUnit" text, 
    PRIMARY KEY ("parentId", "childId") 
) WITH CLUSTERING ORDER BY ("childId" ASC) 
    AND bloom_filter_fp_chance = 0.01 
    AND caching = '{"keys":"ALL", "rows_per_partition":"NONE"}' 
    AND comment = '' 
    AND compaction = {'class': 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy'} 
    AND compression = {'sstable_compression': 'org.apache.cassandra.io.compress.LZ4Compressor'} 
    AND dclocal_read_repair_chance = 0.1 
    AND default_time_to_live = 0 
    AND gc_grace_seconds = 864000 
    AND max_index_interval = 2048 
    AND memtable_flush_period_in_ms = 0 
    AND min_index_interval = 128 
    AND read_repair_chance = 0.0 
    AND speculative_retry = '99.0PERCENTILE'; 
CREATE INDEX purchase_events_clientNumber_idx ON gestor.purchase_events ("clientNumber"); 

任何帮助？

只需附上clientNumber用双引号

例子：select * from purchase_events where "clientNumber" = '100';
