ZREM key member [member ...]

自1.2.0起可用。

时间复杂度: O( M * log(N)),其中 N 是有序集合中元素的数量,M 是要移除的元素的数量。

从存储在的已排序集中移除指定的成员key。不存在的成员被忽略。

key存在时将返回错误,并且不包含有序集合。

返回值

整数回复,具体为:

  • 从排序集中删除的成员数量,不包括非现有成员。历史记录

  • >= 2.4:接受多个元素。在 Redis 2.4 以上的版本中,每次调用都可以删除单个成员。

例子

redis>  ZADD myzset 1 "one" (integer) 1 redis>  ZADD myzset 2 "two" (integer) 1 redis>  ZADD myzset 3 "three" (integer) 1 redis>  ZREM myzset "two" (integer) 1 redis>  ZRANGE myzset 0 -1 WITHSCORES 1) "one" 2) "1" 3) "three" 4) "3"
