Removes the specified fields from the hash stored at `key`.
Specified fields that do not exist within this hash are ignored.
Deletes the hash if no fields remain.
If `key` does not exist, it is treated as an empty hash and this command returns
`0`.

## Examples


HSET myhash field1 "foo"
(integer) 1
HDEL myhash field1
(integer) 1
HDEL myhash field2
(integer) 0


Give these commands a try in the interactive console:


HSET myhash field1 "foo"
HDEL myhash field1
HDEL myhash field2
