renamenx

RENAMENX

RENAMENX key newkey

Renames key to newkey if newkey does not yet exist. It returns an error when key does not exist.

Note: Before Redis 3.2.0, an error is returned if source and destination names are the same.

Return value

Integer reply, specifically:

  • 1 if key was renamed to newkey.
  • 0 if newkey already exists.

Examples

redis> SET mykey "Hello" "OK" redis> SET myotherkey "World" "OK" redis> RENAMENX mykey myotherkey (integer) 0 redis> GET myotherkey "World"
