“没有可行的替代方案，在输入”错误quering cassndra表

Question

时，我有一个表中卡桑德拉波纹管：

CREATE TABLE vroc.sensor_data (
    dpnode text, 
    year int, 
    month int, 
    day int, 
    data_timestamp bigint, 
    data_sensor text, 
    dsnode text, 
    data_quality double, 
    data_value blob, 
    PRIMARY KEY ((dpnode, year, month, day), data_timestamp, data_sensor, dsnode) 
) WITH read_repair_chance = 0.0 
    AND dclocal_read_repair_chance = 0.1 
    AND gc_grace_seconds = 864000 
    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', 'max_threshold' : 32, 'min_threshold' : 4 } 
    AND compression = { 'chunk_length_in_kb' : 64, 'class' : 'org.apache.cassandra.io.compress.LZ4Compressor' } 
    AND default_time_to_live = 0 
    AND speculative_retry = '99PERCENTILE' 
    AND min_index_interval = 128 
    AND max_index_interval = 2048 
    AND crc_check_chance = 1.0; 

然而，当我擦下面的查询

SELECT dpnode, "year", "month", "day", data_timestamp, data_sensor, dsnode, data_quality, data_value 
FROM vroc.sensor_data where dpnode="PSACAB" and "year"=2016 and "month"=11 and day=28; 

我得到异常如下所示：

com.datastax.driver.core.exceptions.SyntaxError: line 2:44 no viable alternative at input 'and' (...FROM vroc.sensor_data where dpnode=["PSACA]B" and...) 
    com.datastax.driver.core.exceptions.SyntaxError: line 2:44 no viable alternative at input 'and' (...FROM vroc.sensor_data where dpnode=["PSACA]B" and...) 

我不知道我在做什么错？

Answer 1

这应该做的伎俩：

select dpnode, year, month, day, data_timestamp, data_sensor, dsnode, data_quality, data_value from vroc.sensor_data where dpnode='PSACAB' and year = 2016 and month = 1 and day = 28; 

基本上字符串应该与'

Answer 2

问题ID在这里进行转义，

dpnode = “PSACAB”

使用dpnode =” PSACAB'来代替。

“” - > ''

希望这有助于
