redis sorted_set 指令操作

score 是set排序的值，越大越在前

1.添加 成員到sorted_set中，并設定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

127.0.0.1:6379> zcard sset1

(integer) 5

3.擷取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

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

127.0.0.1:6379> zincrby sset1 30 val1

"52"

5.将key1和key2...中重複的值得結果存到des-key中，numkeys為源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

127.0.0.1:6379> zinterstore sset5 2 sset1 sset2

(integer) 3

6.擷取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

6.擷取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.擷取成員的索引位置

zrank key member

summary: determine the index of a member in a sorted set

127.0.0.1:6379> zrank sset5 val3

127.0.0.1:6379> zrange sset5 0 10

2) "val2"

3) "val3"

8.從sorted_set 中删除指定的成員（可多個）

zrem key member [member ...]

summary: remove one or more members from a sorted set

9.删除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

10.删除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

11.傳回指定index在start和stop之間，并按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

127.0.0.1:6379> zrevrange sset5 0 2

1) "val3"

3) "val4"

12.傳回指定score在min和max之間，并按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.擷取成員的索引位置，并按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

14.擷取指定成員的score

zscore key member

summary: get the score associated with the given member in a sorted set

127.0.0.1:6379> zscore sset5 val2

"12"

15.連sorted_key顯示結果，并将顯示結果放到目标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
