카산드라 - 타임 스탬프를 어떻게 비교할 수 있습니까?

Question

나는이 테이블이 :

CREATE TABLE mytablename (
    name text, 
    typeid int, 
    activefrom timestamp, 
    status text, 
    PRIMARY KEY ((name), typeid, activefrom) 
) 

나는 일부 쿼리 여기 예를 들어, 타임 스탬프 activefrom의 범위를 조회하고 싶습니다 :

• activefrom> '2000년 1월 2일'
• activefrom을 > '2000-01-02'AND activefrom < '2010-01-02'

SQL에서와 같이 작동하지 않는 것으로 나타났습니다. 예를 들어

name | typeid | activefrom    | status 
------+--------+--------------------------+-------------- 
    dani | 99999 | 1970-01-26 00:00:00+0000 | OK 
    dani | 99999 | 1970-01-26 01:00:00+0000 | OK 
    dani | 99999 | 2070-01-26 00:00:00+0000 | OK 
    dani | 99999 | 1970-01-01 00:00:00+0000 | OK 

검색어 :

dani | 99999 | 2070-01-26 00:00:00+0000 | OK 
    dani | 99999 | 1970-01-01 00:00:00+0000 | OK 

카산드라 버전 :

cqlsh 4.1.1 | Cassandra 2.1.13.1218 | CQL spec 3.1.1 | Thrift protocol 19.39.0 

나는 결과로이이

select * from mytablename where name='dani' and typeid=99999 and activefrom > '2070-01-02 12:51:58+0000'; 

제안 사항이 있으십니까? 고마워요

Answer 1

나는 이것을 시도하고 이것이 내가 가진 것입니다.

cqlsh:test> CREATE TABLE mytablename (
 
    ... name text, 
 
    ... typeid int, 
 
    ... activefrom timestamp, 
 
    ... status text, 
 
    ... PRIMARY KEY ((name), typeid, activefrom) 
 
    ...) 
 
    ... ; 
 

 
cqlsh:test> insert into mytablename (name,typeid,activefrom,status) values ('dani',99999,'1970-01-26 00:00:00+0000','OK'); 
 
cqlsh:test> insert into mytablename (name,typeid,activefrom,status) values ('dani',99999,'1970-01-26 01:00:00+0000','OK'); 
 
cqlsh:test> insert into mytablename (name,typeid,activefrom,status) values ('dani',99999,'2070-01-26 00:00:00+0000','OK'); 
 
cqlsh:test> insert into mytablename (name,typeid,activefrom,status) values ('dani',99999,'1970-01-01 00:00:00+0000','OK'); 
 
cqlsh:test> select * from mytablename; 
 

 
name | typeid | activefrom      | status 
 
------+--------+---------------------------------+-------- 
 
dani | 99999 | 1970-01-01 00:00:00.000000+0000 |  OK 
 
dani | 99999 | 1970-01-26 00:00:00.000000+0000 |  OK 
 
dani | 99999 | 1970-01-26 01:00:00.000000+0000 |  OK 
 
dani | 99999 | 2070-01-26 00:00:00.000000+0000 |  OK 
 

 
(4 rows) 
 
cqlsh:test> select * from mytablename where name='dani' and typeid=99999 and activefrom > '2070-01-02 12:51:58+0000'; 
 

 
name | typeid | activefrom      | status 
 
------+--------+---------------------------------+-------- 
 
dani | 99999 | 2070-01-26 00:00:00.000000+0000 |  OK
