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

Answer 1

You should add a UNIQUE key on ip_addr and then use INSERT IGNORE.

Maybe this helps if you haven't heard of UNIQUE yet: http://www.tutorialspoint.com/sql/sql-unique.htm

Answer 2

you can do that with Insert...on duplicate key update

OR

alternatively you can also be use Replace

Answer 3

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'
);

Answer 4

if I were you, I enforce a UNIQUE constraint on the column,

ALTER TABLE ip_list ADD CONSTRAINT IP_Unique UNIQUE(ip_addr)

Answer 5

Try MySQL INSERT IGNORE statement.
