When I create a table using the following statement, I get an error.
CREATE TABLE HOTEL(ROOM_NUMBER, check_in_date, check_out_date)
Error:
Error Code: 1064. You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near ', check_in_date, check_out_date)' at line 1
What can I do to solve this?

you must have to define datatype like this:
CREATE TABLE HOTEL(
ROOM_NUMBER int,
check_in_date datetime,
check_out_date datetime
);

Trying the below commands on MySQL 5.6 but getting syntax error.
INSERT INTO device
( uid, name, type, os, device_active,
screen_resolution, network_type,status)
VALUES ('1110b','XIAOMI','Android','Android 10',
false,'2340*1080','WIFI',1),
('A2QD1','HUAWEI','Android','Android 7.0',
true,'1920*1080','WIFI',1) As new
ON DUPLICATE KEY
UPDATE device_active = VALUES(new.device_active);
Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'As new ON DUPLICATE KEY UPDATE device_active = VALUES(new.device_active)'

NEW. values are only available in triggers VALUES(device_active) should be enough.
