HMGET key field [field …]
Available since 2.0.0.
Time complexity: O(N) where N is the number of fields being requested.
Returns the values associated with the specified fields
in the hash stored at key
.
For every field
that does not exist in the hash, a nil
value is returned. Because non-existing keys are treated as empty hashes, running HMGET against a non-existing key
will return a list of nil
values.
*Return value
Array reply: list of values associated with the given fields, in the same order as they are requested.
redis> HSET myhash field1 "Hello"

redis> HSET myhash field2 "World"
- (integer) 1
redis> HMGET myhash field1 field2 nofield
- 1) "Hello"
- 2) "World"
