我有卡桑德拉桌 key bigint, upperbound bigint, PRIMARYKEY (key, lowerbound,upperbound)我希望使用CQL执行范围查询。upperbound from schema1 where key=(some key) and lowerbound<=123 order by lowerb
我知道CQL语句中不支持!=。而且,我还知道!=查询效率低下。但是,为什么即使我准备接受过滤,也不允许这样做?例如,我想要这样的东西:Select * from foo where PK='something' and CK1='something' and CK2!='something' allowfiltering我的推理是,在PK和CK1之后,基数将足够低,以至于
使用gocql或gocqlx,没有获取第n个页面的示例: CREATE TABLE IF NOT EXISTS users ( PRIMARY KEY(email)CREATE INDEX IF NOT EXISTS ON users(id); 查询功能: func QueryRows(cqlstring) (res []M.SX) { // M.SX is map[string]interface{}
我希望通过CQL3中的行键以外的复合键来查询数据过滤。,SELECT * FROM grades where subject = 'English' ALLOWFILTERING; //works fine
SELECT * FROM grades where status = 'Active' ALLOWFILT
