Your sample is not working code. You are passing your $sql_delete into prepare and then again into execute. The execute call only needs to pass the $snp hashref keys. Don't use the do method for selects - see DBI docs for why. Some DBDs don't support multiple active statements i.e., you cannot issue a new select until you have read all the rows from a previous select.
