# Redis Rename Command [!(#) Redis Keys](#) The Redis RENAME command is used to change the name of a key. ### Syntax The basic syntax for the Redis RENAME command is as follows: redis 127.0.0.1:6379> RENAME OLD_KEY_NAME NEW_KEY_NAME ### Available Since >= 1.0.0 ### Return Value Returns OK if the rename is successful, otherwise returns an error. Returns an error if OLD_KEY_NAME and NEW_KEY_NAME are the same, or if OLD_KEY_NAME does not exist. When NEW_KEY_NAME already exists, the RENAME command will overwrite the old value. ### Examples ## Examples # Key exists and newkey does not exist redis> SET message "hello world" OK redis> RENAME message greeting OK redis> EXISTS message # message no longer exists (integer)0 redis> EXISTS greeting # greeting now exists (integer)1 # When the key does not exist, an error is returned redis> RENAME fake_key never_exists (error) ERR no such key # When newkey already exists, RENAME overwrites the old newkey redis> SET pc "lenovo" OK redis> SET personal_computer "dell" OK redis> RENAME pc personal_computer OK redis> GET pc (nil) redis> GET personal_computer # The original value dell is overwritten "lenovo" [!(#) Redis Keys](#)
