Redis Keys: RENAME

RENAME key newkey

The Redis RENAME command is used to change the name of a key to newkey.

• It returns an error when the source and destination names are the same, or when a key does not exist.
• If newkey already exists it is overwritten, when this happens RENAME executes an implicit DEL operation, so if the deleted key contains a very big value

Syntax:

RENAME OLD_KEY_NAME NEW_KEY_NAME

Available since

1.0.0.

Return Value
