Redis Incr Command

Redis Strings (string)

The Redis Incr command increments the numeric value stored in the key by one.

If the key does not exist, the key's value will be initialized to 0 first, and then the INCR operation will be performed.

If the value contains an incorrect type, or if the string type value cannot be represented as a number, an error is returned.

The value of this operation is limited to 64 Signed numbers within the range of bit positions.

Syntax

The basic syntax of the Redis Incr command is as follows:

redis　127.0.0.1:6379>　INCR　KEY_NAME

Available Versions

Return Value
