Guys I'm trying to finish this query -> my tag field is set to UNIQUE and I simply want the database to ignore any duplicate tag.
INSERT INTO table_tags (tag) VALUES ('tag_a'),('tab_b'),('tag_c')
ON DUPLICATE KEY IGNORE '*the offending tag and carry on*'
or even this would be acceptable
INSERT INTO table_tags (tag) VALUES ('tag_a'),('tab_b'),('tag_c')
ON DUPLICATE KEY UPDATE '*the offending tag and carry on*'
