redis sorted_set 命令操作

score 是set排序的值，越大越在前
1.添加 成員到sorted_set中，並設置score
ZADD key score member [score member ...]
summary: Add one or more members to a sorted set, or update its score if it already exists
since: 1.2.0
127.0.0.1:6379> zadd sset1 2 val4
(integer) 1




2. 查詢sorted_set的成員數量
ZCARD key
summary: Get the number of members in a sorted set
since: 1.2.0
127.0.0.1:6379> ZCARD sset1
(integer) 5


3.獲取score在min和max之間的數量
ZCOUNT key min max
summary: Count the members in a sorted set with scores within the given values
since: 2.0.0
127.0.0.1:6379> ZCOUNT sset1 12 100
(integer) 2
127.0.0.1:6379> ZCOUNT sset1 0 200000
(integer) 5


4.增加sorted_set中成員的score
ZINCRBY key increment member
summary: Increment the score of a member in a sorted set
since: 1.2.0
127.0.0.1:6379> ZINCRBY sset1 30 val1
"52"


5.將key1和key2...中重複的值得結果存到des-key中，numkeys爲源key的數量
ZINTERSTORE des-key numkeys key1 [key2 ...] [WEIGHTS weight] [AGGREGATE SUM|MIN|MAX]
summary: Intersect multiple sorted sets and store the resulting sorted set in a new key
since: 2.0.0
127.0.0.1:6379> ZINTERSTORE sset5 2 sset1 sset2
(integer) 3


6.獲取sorted_set中index值在start和stop之間的值(包含首末值)
ZRANGE key start stop [WITHSCORES]
summary: Return a range of members in a sorted set, by index
since: 1.2.0


6.獲取sorted_set中index值在min 和max之間的值(包含首末值)
ZRANGEBYSCORE key min max [WITHSCORES] [LIMIT offset count]
summary: Return a range of members in a sorted set, by score
since: 1.0.5
127.0.0.1:6379> ZRANGEBYSCORE sset5 6 11
1) "val4"


7.獲取成員的索引位置
ZRANK key member
summary: Determine the index of a member in a sorted set
since: 2.0.0
127.0.0.1:6379> ZRANK sset5 val3
(integer) 2
127.0.0.1:6379> ZRANGE sset5 0 10
1) "val4"
2) "val2"
3) "val3"


8.從sorted_set 中刪除指定的成員（可多個）
ZREM key member [member ...]
summary: Remove one or more members from a sorted set
since: 1.2.0


9.刪除index值在start和stop之間的成員
ZREMRANGEBYRANK key start stop
summary: Remove all members in a sorted set within the given indexes
since: 2.0.0


10.刪除score值在min和max之間的成員
ZREMRANGEBYSCORE key min max
summary: Remove all members in a sorted set within the given scores
since: 1.2.0


11.返回指定index在start和stop之間，並按score從高到底低排序
ZREVRANGE key start stop [WITHSCORES]
summary: Return a range of members in a sorted set, by index, with scores ordered from high to low
since: 1.2.0
127.0.0.1:6379> ZREVRANGE sset5 0 2
1) "val3"
2) "val2"
3) "val4"


12.返回指定score在min和max之間，並按score從高到底低排序
ZREVRANGEBYSCORE key max min [WITHSCORES] [LIMIT offset count]
summary: Return a range of members in a sorted set, by score, with scores ordered from high to low
since: 2.2.0


13.獲取成員的索引位置，並按score從高到低排序
ZREVRANK key member
summary: Determine the index of a member in a sorted set, with scores ordered from high to low
since: 2.0.0


14.獲取指定成員的score
ZSCORE key member
summary: Get the score associated with the given member in a sorted set
since: 1.2.0


127.0.0.1:6379> ZSCORE sset5 val2
"12"


15.連sorted_key顯示結果，並將顯示結果放到目標key中，numkeys代表源key的數目
ZUNIONSTORE des-key numkeys key1 [key2 ...] [WEIGHTS weight] [AGGREGATE SUM|MIN|MAX]
summary: Add multiple sorted sets and store the resulting sorted set in a new key
since: 2.0.0
