Question

我需要一些帮助才能在表格中插入数据（使用嵌套集合TYPE）列。

我收到以下错误：

来自服务器的错误：代码= 2200 [无效查询]消息=＆＃34;未知字段＆＃39; icon_id＆＃39;用户定义类型的值tst_diag_msg_typ＆＃34;

先谢谢你的帮助!!

这是我正在做的事情：

CREATE TYPE cs_veh.tst_icon_typ (
   icon_id text,
   icon_val text
);


CREATE TYPE cs_veh.tst_diag_msg_typ (
   msg_id text,
   msg_priority int,
   msg_text text,
   IconReason SET <FROZEN<tst_icon_typ>> 
);


CREATE TABLE test_veh_health
(VIN text,
eventtimestamp timestamp,
DiagnosticMessages SET < FROZEN <tst_diag_msg_typ>>,
PRIMARY KEY((VIN),eventtimestamp ))
WITH CLUSTERING ORDER BY (eventtimestamp DESC);
insert into test_veh_health
( VIN,
  eventtimestamp
, DiagnosticMessages 
)
values
('TEST122227751',
 toTimestamp(now())
,{{msg_id : '24.0:ENGINE:MESSAGE', msg_priority : 37, msg_text : 'Oil pressure: Engine off! See owners manual.' }
, { icon_id : 'xx',    icon_val: 'text'}
}
);

Answer 1

尝试以下插入声明：

INSERT INTO test_veh_health(vin, eventtimestamp, diagnosticmessages) VALUES (
    'TEST122227751', 
    toTimestamp(now()),
    {
      {
        msg_id : '24.0:ENGINE:MESSAGE', 
        msg_priority : 37, 
        msg_text : 'Oil pressure: Engine off! See owners manual.' , 
        iconreason : { 
          {
            icon_id : 'xx',
            icon_val: 'text'
          }
        }
      }
    }
);

输出：

cqlsh:test> SELECT * FROM test_veh_health ;

@ Row 1

 vin                | TEST122227751
 eventtimestamp     | 2017-08-11 19:07:27.545000+0000
 diagnosticmessages | {{msg_id: '24.0:ENGINE:MESSAGE', msg_priority: 37, msg_text: 'Oil pressure: Engine off! See owners manual.', iconreason: {{icon_id: 'xx', icon_val: 'text'}}}}

@ Row 2

 eventtimestamp     | 2017-08-11 18:54:57.519000+0000
 diagnosticmessages | null
