Below is the code I’m using to run the query, parse the result set, and parse the rows (respectively)

$exec_ret = $DBS->SQLExecSQL($STMT);  while ($DBS->SQLFetch() == *PLibdata::RET_OK) {       $rowfetch = $DBS->{Row}->GetCharValue($colname[$i]); }

Can I grab the column/field name of a temp table using similar syntax? $colname[$i] is predefined at the top to hold the column/field names. This is hard-coded right now, but I would rather automate it by pushing values into $colname inside of a loop that runs before the rows are parsed.

  1. What module are you using for database access? I don’t recognize the method names.

    If you’re using DBI, you can get the column names from the statement handle after executing it:

    my $sth = $dbh->prepare($STMT); $sth->execute; my $columns = $sth->{NAME_uc};  while (my $row = $sth->fetch) {   for my $i (0 .. $#$row) {     print '$columns->[$i]: $row->[$i]\n';   }   print '\n'; }

    There are 3 versions of the column names: NAME gives the column names as the database returns them, NAME_lc converts them to all lower case, and NAME_uc converts them to all upper case. If you care about database independence, I suggest you avoid NAME and use one of the other two.
