Question

i’m doing an insert into a mysql db from perl. i’m getting a duplicate error after the 1st insert. here is the code i’m using for the insert. i’m pulling an id from a json response. i have output of what i’m receiving below the code

  foreach my $listing(@{$json_text->{listings}})
    {
      my $id = $listing->{id};
   print "\nid = $id \n";


    # DO THE INSERT
    my $query_insert = "INSERT INTO calendar (id) VALUES ($id)";
    print "query insert = $query_insert \n";
    my $query = $db->do($query_insert); 
   print "query = $query \n";

    } #end foreach

here is the output i’m receiving. (returns didn’t copy over right. so the below looks off, but the right data is there). this is like 133
my $query = $db->do($query_insert);

id = 2576246314
query insert = INSERT INTO calendar (id) VALUES (2576246314)
query = 1

id = 2576246678
query insert = INSERT INTO calendar (id) VALUES (2576246678)

Answer 1

It sounds like the type for id is too short. That value in your "duplicate entry" message (2147483647) is the maximum signed 32-bit integer value. Try using a larger size for ID.
