OK
redis> SET song "secret base - Zone"
OK
redis> MOVE song 1                          # Move song to database 1

(integer) 0
redis> SELECT 1                             # Use database 1
OK
redis:1> EXISTS song                        # Confirm that song has been moved to the database 1 (Note that the command prompt has changed to "redis:1" indicates that the database is being used 1)
(integer) 1
# When the key does not exist
redis:1> EXISTS fake_key
(integer) 0
redis:1> MOVE fake_key 0                    # Attempt to move from database 1 Move a non-existent key to database 0, failed
(integer) 0
redis:1> select 0                           # Use database 0
OK
redis> EXISTS fake_key                      # Verify that fake_key does not exist
(integer) 0
# When the source database and the target database have the same key
redis> SELECT 0                             # Use database 0
OK
redis> SET favorite_fruit "banana"

redis> SELECT 1                             # Use database1

OK
redis:1> SELECT 0                           # Use database 0 and try to move favorite_fruit to the database 1
OK
redis> MOVE favorite_fruit 1                # Because two databases have the same key, the MOVE command fails
(integer) 0
redis> GET favorite_fruit                   # The favorite_fruit in database 0 has not changed
"banana"
redis> SELECT 1
OK
