HINCRBY

Syntax
HINCRBY key field increment
Available since:
2.0.0
Time complexity:
O(1)
ACL categories:
@write, @hash, @fast,

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.

Return

Integer reply: the value at field after the increment operation.

Examples

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

HSET myhash field 5 HINCRBY myhash field 1 HINCRBY myhash field -1 HINCRBY myhash field -10
