ZINCRBY key increment member

自1.2.0起可用。

时间复杂度: O( log(N))其中 N 是排序集合中元素的数量。

增量的得分member在存储在有序集合keyincrement。如果member不存在于有序集合中,则将increment其与其分数相加(就像其以前的分数一样0.0)。如果key不存在,member则创建一个指定为其唯一成员的新排序集。

key存在但返回一个错误,但不包含有序集合。

score值应该是数值的字符串表示形式,并且可以接受双精度浮点数。有可能提供一个负值来减少分数。

返回值

批量字符串回复:(member双精度浮点数)的新分数,表示为字符串。

例子

redis>  ZADD myzset 1 "one" (integer) 1 

redis>  ZADD myzset 2 "two" (integer) 1 

redis>  ZINCRBY myzset 2 "one" "3" 

redis>  ZRANGE myzset 0 -1 WITHSCORES 1) "two" 2) "2" 3) "one" 4) "3"
