I have an access database that I need to update only if my information is unique. Is there a simple sql statement to accomplish this? Will ‘insert ignore’ work with access?
Example: I have the info stored in an array (‘bob’,’34’,’hair’). If my database contains a record that matches on those three columns I would not want it to be inserted. If it was found to be unique I would like it to be inserted.
I am writing this in cold fusion but just cant seem to get the sql right.
Before doing an insert, do a select for those values. If you don’t get a record back then you know it is safe to insert. Just use two separate queries, one for the check, and if no record found, then the insert.
