DELETE List

DELETE로 List 데이터를 삭제

DELETE로 List 데이터를 삭제합니다.

테스트 데이터 입력

Example

명령>rpush mylist1 value10 value30 value50 value20 value40
결과>5
명령>rpush mylist2 110 120 130 140 150
결과>5
명령>rpush mylist3 AAA BBB CCC DDD EEE
결과>5

Key로 삭제

DELETE FROM LIST.MYLIST1

키 하나를 지정하거나 '*'를 사용해서 여러 개 키를 삭제할 수 있습니다.

Example

명령>select * from list.mylist*;
결과>   0) key|value
  1) mylist1|value10
  2) mylist1|value30
  3) mylist1|value50
  4) mylist1|value20
  5) mylist1|value40
  6) mylist2|110
  7) mylist2|120
  8) mylist2|130
  9) mylist2|140
10) mylist2|150
11) mylist3|AAA
12) mylist3|BBB
13) mylist3|CCC
14) mylist3|DDD
15) mylist3|EEE
명령>delete from list.mylist1;  opcode
결과> 1 keys deleted
명령>delete from list.mylist*;  opcode
결과> 2 keys deleted

WHERE 조건

비교: =, <, <=, >, >=, !=, <>

Where 조건으로 키를 삭제할 수 있습니다.
삭제 명령은 키가 지워지므로 필요한 키를 다시 넣고 시작하세요.
주의할 점은 where 조건에 value를 사용할 경우에도 키가 삭제됩니다.
Value만 삭제할 경우 레디스 원래 명령을 사용하세요.

Example

명령>delete from list.* where key > 'mylist2';   opcode
결과> 1 keys deleted
명령>delete from list.* where value = 'value10';   opcode
결과> 1 keys deleted
명령>delete from list.* where value <= 'BBB';   opcode
결과> 1 keys deleted

BETWEEN, NOT BETWEEN

Example

명령>delete from list.* where key between 'mylist1' and 'mylist2';   opcode
결과> 2 keys deleted
명령>delete from list.* where key not between 'mylist1' and 'mylist2';   opcode
결과> 1 keys deleted
데이터 입력
명령>delete from list.* where value between 120 and 140;   opcode
결과> 1 keys deleted
명령>delete from list.* where value between 'BBB' and 'value30';   opcode
결과> 2 keys deleted

IN, NOT IN

Example

명령>delete from list.* where key in ('mylist1','mylist2')   opcode
결과> 2 keys deleted
데이터 입력
명령>delete from list.* where value in ('value10','CCC');   opcode
결과> 2 keys deleted
명령>delete from list.* where value not in ('value10');   opcode
결과> 1 keys deleted

GLOB, NOT GLOB

*(별표), ?(물음표)
대소문자를 구분한다.

Example

명령>delete from list.* where value glob 'value*';   opcode
결과> 1 keys deleted
명령>delete from list.* where value glob 'a*';   opcode
결과> 0 keys deleted
명령>delete from list.* where value not glob 'a*';   opcode
결과> 2 keys deleted

LIKE, NOT LIKE

%(퍼센트), _(밑줄)
대소문자를 구분하지 않는다.

Example

명령>delete from list.* where value like 'value%';   opcode
결과> 1 keys deleted
명령>delete from list.* where value like 'A%';   opcode
결과> 1 keys deleted
명령>delete from list.* where value not like 'value%';   opcode
결과> 1 keys deleted
