HMSET writes each field and value pair into the hash at key, creating the hash if needed. It behaves exactly like HSET (including removing the time to live of each field it overwrites), except that it replies OK instead of the number of new fields. New code should use HSET, which accepts several pairs too.

Return value

Section titled “Return value”
Case RESP2 RESP3
Success Simple string OK Simple string OK

Errors:

  • WRONGTYPE if key holds a value that is not a hash.
  • ERR wrong number of arguments for 'hmset' command if no pair is given or a field has no value.

Examples

Section titled “Examples”
127.0.0.1:6379> HMSET user:1 name "Ada" lang "en"
OK
127.0.0.1:6379> HGET user:1 lang
"en"

Compatibility

Section titled “Compatibility”

Same as Redis 7.4 and Valkey 8, where it is also deprecated in favour of HSET.
