通过 CQLsh (Cassandra) 插入硬编码的 UUID

问题描述

想通过 CQLsh 脚本填充一些静态测试数据.

这不起作用:(device_id 是 UUID)

插入设备(device_id、geohash、name、external_identifier、measures、tags)值('c37d661d-7e61-49ea-96a5-68c34e83db3a'、'9q9p3yyrn1'、'Acme1'、'936'、{'aparPower'、'actPower'、'actEnergy'}、{'make':'Acme'});

错误请求:无效的 STRING 常量(c37d661d-7e61-49ea-96a5-68c34e83db3a) 用于 uuid 类型的 device_id

我似乎找不到任何可转换为正确类型的 CQL 函数.我需要从 python 脚本中执行此操作吗?

谢谢，克里斯

解决方案

你不应该在 UUID 周围加上引号以阻止它被解释为字符串，即

插入设备(device_id、geohash、name、external_identifier、measures、tags)价值观(c37d661d-7e61-49ea-96a5-68c34e83db3a,'9q9p3yyrn1', 'Acme1', '936', {'aparPower','actPower','actEnergy'},{'make':'Acme'});

Would like to populate some static test data via a CQLsh script.

This doesn't work: (device_id is UUID)

insert into devices (device_id, geohash,name, external_identifier, measures, tags)
values ('c37d661d-7e61-49ea-96a5-68c34e83db3a','9q9p3yyrn1', 'Acme1', '936', {'aparPower','actPower','actEnergy'},{'make':'Acme'});

I can't seem to find any CQL function to convert to proper type. Do I need to do this from a python script?

Thanks,Chris

解决方案

You shouldn't put the quotes around the UUID to stop it being interpreted as a string i.e.

insert into devices (device_id, geohash,name, external_identifier, measures, tags)
 values
(c37d661d-7e61-49ea-96a5-68c34e83db3a,'9q9p3yyrn1', 'Acme1', '936', {'aparPower','actPower','actEnergy'},{'make':'Acme'});
