HINCRBY key field increment

Increments the number stored at field in the hash stored at key by increment. If key does not exist, a new key holding a hash is created. If field does not exist the value is set to 0 before the operation is performed.

The range of values supported by HINCRBY is limited to 64 bit signed integers.

valkey-protocol(7) Integer reply: the value of the field after the increment operation.

• Available since: 2.0.0

Since the increment argument is signed, both increment and decrement operations can be performed:

127.0.0.1:6379> HSET myhash field 5
(integer) 1
127.0.0.1:6379> HINCRBY myhash field 1
(integer) 6
127.0.0.1:6379> HINCRBY myhash field -1
(integer) 5
127.0.0.1:6379> HINCRBY myhash field -10
(integer) -5
