I have a table with a unique key for two columns:
CREATE TABLE `xpo`.`user_permanent_gift` (
`id` INT UNSIGNED NOT NULL AUTO_INCREMENT ,
`fb_user_id` INT UNSIGNED NOT NULL ,
`gift_id` INT UNSIGNED NOT NULL ,
`purchase_timestamp` TIMESTAMP NULL DEFAULT now() ,
PRIMARY KEY (`id`) ,
UNIQUE INDEX `user_gift_UNIQUE` (`fb_user_id` ASC, `gift_id` ASC) );
I want to insert a row into that table, but if the key exists, to do nothing! I don't want an error to be generated because the keys exist.
I know that there is the following syntax:
INSERT ... ON DUPLICATE KEY UPDATE ...
but is there something like:
INSERT ... ON DUPLICATE KEY DO NOTHING
