sql - How to only insert unique data into an access database -
i have access database need update if information unique. there simple sql statement accomplish this? 'insert ignore' work access?
example: have info stored in array ('bob','34','hair'). if database contains record matches on 3 columns not want inserted. if found unique inserted.
i writing in cold fusion cant seem sql right.
before doing insert, select values. if don't record know safe insert. use 2 separate queries, 1 check, , if no record found, insert.
