SADD key member [member ...]

自1.0.0起可用。

时间严重年夜度: O(1)为每个元素添加,以是O(N)在用多个参数挪用该敕令时添加N个元素。

将指定的成员添加到存储在的荟萃中key。指定的曾经是该组成员的成员将被忽视。假定key华夏棋牌不存在,则在添加指定成员之前培植一个新集。

当存储的值key华夏棋牌不是集应时,将前往弱点。

前往值

华夏棋牌整数回复:添加到荟萃中的元素数目,不网罗荟萃中曾经存在的一切元素。

历史

  • >= 2.4:吸收多个member参数。2.4之前的 Redis 版本只能为每个召唤添加一个成员。

例子

redis>  SADD myset "Hello" (integer) 1 

redis>  SADD myset "World" (integer) 1 

redis>  SADD myset "World" (integer) 0 

redis>  SMEMBERS myset 1) "Hello" 2) "World"
