HVALS
Syntax
HVALS key
- Available since:
- Redis Open Source 2.0.0
- Time complexity:
- O(N) where N is the size of the hash.
- ACL categories:
-
@read,@hash,@slow,
Returns all values in the hash stored at key.
Examples
redis> HSET myhash field1 "Hello"
(integer) 1
redis> HSET myhash field2 "World"
(integer) 1
redis> HVALS myhash
