SELECT

SELECT *
SELECT key, value
SELECT key
SELECT value
SELECT key key_name or key AS key_name --> alias(별명) 사용 가능

FROM

FROM set.*
FROM set.myset*
FROM set.myset1

SELECT * FROM SET.MYSET*

Set의 키와 값(value)를 조회한다.

Example

명령>	select * from set.myset*;
결과>	0) key\|value 1) myset1\|mem30 2) myset1\|mem20 3) myset1\|mem40 4) myset1\|mem10 5) myset1\|mem50 6) myset2\|10 7) myset2\|20 8) myset2\|30 9) myset2\|40 10) myset2\|50 11) myset3\|23.4 12) myset3\|34.5 13) myset3\|12.3 14) myset3\|45.6 15) myset3\|56.7
명령>	select * from set.myset1;
결과>	0) key\|value 1) myset1\|mem30 2) myset1\|mem20 3) myset1\|mem40 4) myset1\|mem10 5) myset1\|mem50
명령>	select key from set.myset*;
결과>	0) key 1) myset1 2) myset2 3) myset3

ORDER BY

정렬(sort)해서 보여준다.

Example

명령>	select value from set.myset1 order by value;
결과>	0) value 1) mem10 2) mem20 3) mem30 4) mem40 5) mem50
명령>	select value from set.myset1 order by value desc;
결과>	0) value 1) mem50 2) mem40 3) mem30 4) mem20 5) mem10

정렬(sort) 순서: 숫자 < 문자
레디스에서는 숫자와 문자를 같이 소트할 수 있습니다. 숫자는 문자보다 작은 것으로 취급합니다.

Example

명령>	select * from set.myset* order by value;
결과>	0) key\|value 1) myset2\|10 2) myset3\|12.3 3) myset2\|20 4) myset3\|23.4 5) myset2\|30 6) myset3\|34.5 7) myset2\|40 8) myset3\|45.6 9) myset2\|50 10) myset3\|56.7 11) myset1\|mem10 12) myset1\|mem20 13) myset1\|mem30 14) myset1\|mem40 15) myset1\|mem50

LIMIT

출력 행 수를 제한한다.

Example

명령>	select * from set.myset* order by value limit 5;
결과>	0) key\|value 1) myset2\|10 2) myset3\|12.3 3) myset2\|20 4) myset3\|23.4 5) myset2\|30
명령>	select * from set.myset* order by value desc limit 5;
결과>	0) key\|value 1) myset1\|mem50 2) myset1\|mem40 3) myset1\|mem30 4) myset1\|mem20 5) myset1\|mem10

LIMIT OFFSET

몇 행 건너 출력

offset을 사용하면 지정한 숫자만큼 건너뛰고 출력합니다. 3을 지정하면 3행을 건너뛰고 4행부터 출력합니다.
offset을 생략하고 컴마(,)를 사용할 경우 offset 숫자를 앞에 위치시킵니다.

Example

명령>	select * from set.myset* order by value limit 5 offset 3; --> 3행 건너 5행 출력
결과>	0) key\|value 1) myset3\|23.4 2) myset2\|30 3) myset3\|34.5 4) myset2\|40 5) myset3\|45.6
명령>	select * from set.myset* order by value limit 3, 5; --> 3행 건너 5행 출력
결과>	0) key\|value 1) myset3\|23.4 2) myset2\|30 3) myset3\|34.5 4) myset2\|40 5) myset3\|45.6

FUNCTIONS

COUNT(), CARD()

개수를 조회한다.
card()는 list, set, zset, hash, stream에서 값(value)의 개수를 조회하는데 사용된다.
아래 세 번째 예처럼 card()를 사용하는 것이 네 번째 예처럼 group by key를 사용하는 것보다 훨씬 속도가 빠르다.

Example

명령>	select *count()** from set.myset*;
결과>	0) count(*) 1) 15
명령>	select count(key) from set.myset*;
결과>	0) count(key) 1) 3
명령>	select key, card(key) from set.myset*;
결과>	0) key\|card(key) 1) myset1\|5 2) myset2\|5 3) myset3\|5
명령>	select *key, count()** from set.myset* group by key;
결과>	0) key\|count(*) 1) myset1\|5 2) myset2\|5 3) myset3\|5

MAX(), MIN()

최댓값, 최솟값을 조회한다.
레디스에서는 문자와 숫자를 같은 선상에 놓고 비교할 수 있습니다.
숫자는 문자보다 작은 것으로 취급해서 min, max를 계산합니다.

Example

명령>	select min(value),max(value) from set.myset1;
결과>	0) min(value)\|max(value) 1) mem10\|mem50
명령>	select min(value),max(value) from set.myset*;
결과>	0) min(value)\|max(value) 1) 10\|mem50
명령>	select key,min(value),max(value) from set.myset* group by key;
결과>	0) key\|min(value)\|max(value) 1) myset1\|mem10\|mem50 2) myset2\|10\|50 3) myset3\|12.3\|56.7

MAX(value1, value2): 둘 중 큰 값 출력
MIN(value1, value2): 둘 중 작은 값 출력

Example

명령>	select max('A','B')
결과>	0) max('A','B') 1) B
명령>	select max(30,value) from set.myset2;
결과>	0) max(30,value) 1) 30 2) 30 3) 30 4) 40 5) 50
명령>	select min('mem30',value) from set.myset1;
결과>	0) min('mem30',value) 1) mem30 2) mem20 3) mem30 4) mem10 5) mem30

숫자 함수

SUM(), AVG()

합계, 평균을 구한다.

Example

명령>	select sum(value) from set.myset2;
결과>	0) sum(value) 1) 150
명령>	select avg(value) from set.myset2;
결과>	0) avg(value) 1) 30.0

문자, 숫자가 섞여 있을 경우에는 숫자만 계산한다.

Example

명령>	select sum(value) from set.myset*
결과>	0) sum(value) 1) 322.5

기타 함수

group_concat

Example

명령>	select key,group_concat(value) from set.myset1;
결과>	0) key\|group_concat(value) 1) myset1\|mem10,mem40,mem30,mem20,mem50
명령>	select key,group_concat(value,'') from set.myset1;
결과>	0) key\|group_concat(value) 1) myset1\|mem10mem40mem30mem20mem50
명령>	select key,group_concat(value,' and ') from set.myset1;
결과>	0) key\|group_concat(value) 1) myset1\|mem10 and mem40 and mem30 and mem20 and mem50

WHERE 조건

비교: =, <, <=, >, >=, !=, <>

값(value) 비교: 숫자

Example

명령>	select * from set.myset2 where value = 30;
결과>	0) key\|value 1) myset2\|30
명령>	select * from set.myset2 where value > 30;
결과>	0) key\|value 1) myset2\|40 2) myset2\|50

결과>	0) key\|value 1) myset2\|10 2) myset2\|20
명령>	select * from set.myset2 where value != 30;
결과>	0) key\|value 1) myset2\|10 2) myset2\|20 3) myset2\|40 4) myset2\|50

값(value) 비교: 문자

결과>	0) key\|value 1) myset1\|mem10 2) myset1\|mem40 3) myset1\|mem20 4) myset1\|mem50

AND, OR

Example

명령>	select * from set.myset2 where value >= 20 and value < 40;
결과>	0) key\|value 1) myset2\|20 2) myset2\|30
명령>	select * from set.myset2 where value <= 20 or value > 40;
결과>	0) key\|value 1) myset2\|10 2) myset2\|20 3) myset2\|50

BETWEEN

Example

명령>	select * from set.myset2 where value between 20 and 40;
결과>	0) key\|value 1) myset2\|20 2) myset2\|30 3) myset2\|40
명령>	select * from set.myset2 where value not between 20 and 40;
결과>	0) key\|value 1) myset2\|10 2) myset2\|50

GLOB

*(별표), ?(물음표)
대소문자를 구분한다.

[AB]: A, B 문자가 들어간 문자열를 검색할 경우
[A-C]: A에서 C까지(A,B,C) 문자가 들어간 문자열을 검색할 경우
[A-Z]: 알파벳 대문자가 들어가 문자열을 검색할 경우
[a-z]: 알파벳 소문자가 들어가 문자열을 검색할 경우
[A-Za-z]: 알파벳이 들어가 문자열을 검색할 경우
[A-z]: 이렇게 지정하면 Z와 a 사이에 [,\,],^,_,' 가 있어서 이런 특수문자가 포함됩니다.

Example

명령>	insert into set values('myset4','USER-A01','USER-A02','USER-B01','USER-B02','USER-C01');
결과>	1 inserted
명령>	select * from set.myset4 where value *glob 'USER-A'**;
결과>	0) key\|value 1) myset4\|USER-A02 2) myset4\|USER-A01
명령>	select * from set.myset4 where value *glob '01'*;
결과>	0) key\|value 1) myset4\|USER-A01 2) myset4\|USER-B01 3) myset4\|USER-C01
명령>	select * from set.myset4 where value *glob 'USER-[AC]'**;
결과>	0) key\|value 1) myset4\|USER-A02 2) myset4\|USER-A01 3) myset4\|USER-C01

NOT GLOB

Example

명령>	select * from set.myset4 where value *not glob 'USER-A'**;
결과>	0) key\|value 1) myset4\|USER-B02 2) myset4\|USER-B01 3) myset4\|USER-C01
명령>	select * from set.myset4 where value *not glob '01'*;
결과>	0) key\|value 1) myset4\|USER-A02 2) myset4\|USER-B02
명령>	select * from set.myset4 where value *not glob 'USER-[AC]'**;
결과>	0) key\|value 1) myset4\|USER-B02 2) myset4\|USER-B01

LIKE

%(퍼센트), _(밑줄)
대소문자를 구분하지 않는다.
가능하면 LIKE를 사용하지 말고 GLOB를 사용하세요.
LIKE는 대소문자를 구분하지 않기 때문에 검색 범위가 넓어서 GLOB보다 속도가 느립니다.

Example

명령>	select * from set.myset4 where value like 'user-a%';
결과>	0) key\|value 1) myset4\|USER-A02 2) myset4\|USER-A01
명령>	select * from set.myset4 where value like '%01%';
결과>	0) key\|value 1) myset4\|USER-A01 2) myset4\|USER-B01 3) myset4\|USER-C01

NOT LIKE

Example

명령>	select * from set.myset4 where value not like 'user-a%';
결과>	0) key\|value 1) myset4\|USER-B02 2) myset4\|USER-B01 3) myset4\|USER-C01
명령>	select * from set.myset4 where value not like '%01%';
결과>	0) key\|value 1) myset4\|USER-A02 2) myset4\|USER-B02

IN

Example

명령>	select key from set.myset* where key in ('myset1','myset2');
결과>	0) key 1) myset1 2) myset2
명령>	select * from set.myset1 where value in ('mem10','mem30');
결과>	0) key\|value 1) myset1\|mem10 2) myset1\|mem30
명령>	select * from set.myset2 where value in (20,40);
결과>	0) key\|value 1) myset1\|20 2) myset1\|40

NOT IN

Example

명령>	select key from set.myset* where key not in ('myset1','myset2');
결과>	0) key 1) myset3 2) myset4
명령>	select * from set.myset1 where value not in ('mem10','mem30');
결과>	0) key\|value 1) myset1\|mem40 2) myset1\|mem20 3) myset1\|mem50
명령>	select * from set.myset2 where value not in (20,40);
결과>	0) key\|value 1) mylist2\|10 2) mylist2\|30 3) mylist2\|50

GROUP BY

Example

명령>	select key,*count()** from set.myset* group by key; --> 이것 보다는 select key, card(key) from set.myset*; 를 사용하세요. 속도가 훨씩 빠릅니다.
결과>	0) key\|count(*) 1) myset1\|5 2) myset2\|5 3) myset3\|5 4) myset4\|5
명령>	select key,min(value),max(value) from set.myset* group by key;
결과>	0) key\|min(value)\|max(value) 1) myset1\|mem10\|mem50 2) myset2\|10\|50 3) myset3\|12.3\|56.7 4) myset4\|USER-A01\|USER-C01

성능 Performance

테스트 데이터 입력

redis-benchmark를 이용해서 총 30만개 키를 입력합니다.
setA 10만개, setB 10만개, setC 10만개.

쿼리 성능

select * from set.myset1; -> (270us) full value scan opcode
select value from set.myset1 order by value; -> (297us) full value scan, sort opcode
select count(*) from set.set*; -> count: 300286 (201us) key scan, get count opcode
select key, card(key) from set.set*; -> (232us) key scan, get count opcode
select key, count(*) from set.set* group by key; -> (28ms) full value scan opcode
--> group by count는 속도가 느립니다. card(key)를 사용하세요.
select value from set.setA order by value limit 50000, 10; -> (87ms) full value scan, sort opcode
select * from set.setA where value = 'ele_000463064363'; -> (276us) direct search opcode
select * from set.setA where value in ('ele_000463064363'); -> (280us) direct search opcode
--> Set에서 value에 equal(=)는 direct search로 속도가 빠릅니다.
