SADD

Usage:

SADD key member [ member ...]

Complexity:

O(1) for each element added, so O(N) to add N elements when the command is called with multiple arguments.

Since:

1.0.0

Add the specified members to the set stored at key. Specified members that are already a member of this set are ignored. If key does not exist, a new set is created before adding the specified members.

An error is returned when the value stored at key is not a set.

Examples

SADD myset "Hello"
SADD myset "World"
SADD myset "World"
SMEMBERS myset
