- Usage:
-
INCRBY key increment
- Complexity:
- O(1)
- Since:
- 1.0.0
Increments the number stored at key by increment.
If the key does not exist, it is set to 0 before performing the operation.
An error is returned if the key contains a value of the wrong type or contains a
string that can not be represented as integer.
This operation is limited to 64 bit signed integers.
See INCR for extra information on increment/decrement operations.
Examples
127.0.0.1:6379> SET mykey "10"
OK
127.0.0.1:6379> INCRBY mykey 5
(integer) 15
