Insert query check if record exists - If not, Insert it [duplicate]

Answer 1

You can use below query. Here it will insert the ip_address when it is not present in your table.

INSERT INTO ip_list (ip_addr)
SELECT * FROM (SELECT '192.168.100.1') AS tmp
WHERE NOT EXISTS (
    SELECT ip_addr FROM ip_list WHERE ip_addr='192.168.100.1'
);
