Thanks for the DBI Hints. But talking about 1st and last row, I would like to add a reminder for the SQL:

Never count on the order of rows in an SQL-Select unless you use order by. Even if every day experience may tell you something different and you use tricks like indices etc, but that is just by accident. The result is a set, which is unordered per definitionem.

It is just the first row that gets lost, but that gives no clue about the contents of the row.
