我想在表格中插入一个简单的行。有人能指出这里发生了什么吗?

CREATE TABLE recommendation_engine_poc.user_by_category (
        game_category text,
        customer_id text,
        amount double,
        game_date timestamp,
        PRIMARY KEY (game_category, customer_id)
    ) WITH CLUSTERING ORDER BY (customer_id 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';

    cqlsh:recommendation_engine_poc> insert into user_by_category  ('game_category','customer_id') VALUES ('Goku','12') ;
    SyntaxException: <ErrorMessage code=2000 [Syntax error in CQL query] message="line 1:31 no viable alternative at input 'game_category' (insert into user_by_category  (['game_categor]...)">

语法错误。你在这里:

  

插入user_by_category(game_category,customer_id)VALUES   (&#39;悟空&#39;&#39; 12&#39);

或:

  

插入user_by_category(&#34; game_category&#34;,&#34; customer_id&#34;)VALUES   (&#39; Kakarot&#39;&#39; 12&#39);

第二个通常用于区分大小写的列名称。

这个问题有两个原因,

  1. 双引号(")代替单引号(')
  2. 在 IN 命令中的值后输入键
  3. 字符编码

所以在使用像 IN 命令这样的过滤器时
从数据库中选择列,其中 column_name IN('xyz','yzx')
单行 IN 命令

它应该在单行而不是
从数据库中选择列,其中 column_name IN('xyz',
'yzx')
多行输入命令
