**`HMSET key field value [field value ...]`**

This command sets the data for the given `field` with the given `value` in the hash that is specified by `key`.

- If the given `field` already exists in the specified hash, this command overwrites the existing value with the given `value`.
- If the given `key` does not exist, a new hash is created for the `key`, and the given values are inserted to the associated given fields.
- If the given `key` is associated with a non-hash data, an error is raised.
