in thread DBD::CSV failing

Okay, I'm back (again). Using $sth->fetchrow_hashref seems to be solving my problem. I have discovered that one cannot use $sth->fetch if one chooses to execute a query containing conditionals based on fields; i.e.
$sth->prepare("SELECT * FROM db WHERE field < 2000"); while (@row = $sth->fetch) { ... }
will return the first row and then nothing beyond that. If I use
while ($row = $sth->fetchrow_hashref) { ...
for some reason, everything seems to be hunky dory. Also, that "undef" in setting up the column names and variable references also is wont to cause me difficulty ("perldoc DBD::CSV" for reference on that one). Go figure.

    Your code:
    while (@row = $sth->fetch) # don't do this
    is wrong. In DBI, fetch() is an alias for fetchrow_arrayref so its return is a scalar (an array reference), not an array.
