Question

创建表格：

CREATE TABLE notifications (
  id uuid PRIMARY KEY,
  user_id bigint,
  received_datetime timestamp,
  );

cqlsh：

select count(*)
  from notifications
  where received_datetime >='2016-10-11 00:00:00'
    and received_datetime >='2016-10-18 00:00:00'
  ALLOW FILTERING;

错误： -

InvalidRequest: Error from server: code=2200 [Invalid query] message="More than one restriction was found for the start bound on received_datetime"

Answer 1

我猜你真正想要的是以下查询：

select count(*) from notifications
    where received_datetime >='2016-10-11 00:00:00' 
    and received_datetime <='2016-10-18 00:00:00' 
    ALLOW FILTERING;

否则，您可以通过选择更严格的条件将两个下限条件合并为一个：

select count(*) from notifications
    where received_datetime >= '2016-10-18 00:00:00'
    ALLOW FILTERING;
