Redis SADD Command

Redis Sets

The Redis SADD command adds one or more member elements to a set. Member elements that already exist in the set will be ignored.

If the set key does not exist, a new set containing only the added elements as members is created.

An error is returned if the set key is not of the set type.

Note: Prior to Redis 2.4, SADD only accepted a single member value.

Syntax

The basic syntax of the redis SADD command is as follows:

redis 127.0.0.1:6379> SADD KEY_NAME VALUE1..VALUEN

Available Versions

= 1.0.0

Return Value

The number of new elements added to the set, excluding any ignored elements.

Example

redis 127.0.0.1:6379> SADD myset "hello"
(integer) 1
redis 127.0.0.1:6379> SADD myset "foo"
(integer) 1
redis 127.0.0.1:6379> SADD myset "hello"
(integer) 0
redis 127.0.0.1:6379> SMEMBERS myset
1) "hello"
2) "foo"
