What is the difference between HSET and HMSET method in redis database

Question

In my application im using redis database.I have gone through their documentation but i couldn\'t find the difference between HSET and HMSET.

Answer 1

The only difference between the commands HSET and HMSET is the return value of the commands.

HSET return value (Integer reply):

• # if the field is a new field in the hash and value was set. (where # is the number of new fields created )
• 0 if the field already exists in the hash and the value was updated.

HMSET returns a simple string as a reply.
