Om!

Problem: 
my $dbh = DBI->connect("dbi:Sybase:server=$percdb", $user, $passwd,
                            {'RaiseError' => 1}
                        );
if ($DBI::errstr) {
    FATAL($DBI::errstr);
    exit 1;
}
else {
    DEBUG('Successfully connected to database!');
}

my $sth = $dbh->prepare($QUERY);
$sth->execute;
handle_db_error();
$result_hash = $sth->fetchall_hashref('ent_id');
handle_db_error();

sub handle_db_error { 
    if ($dbh->err) { 
        FATAL("Error: $DBI::errstr"); 
        exit 9;
    }
}

You see that I connect to the database and try to fetch all rows into a hash. It works most of the time and always from the shell (though not always when called from cron - strange!) Now my problem is that sometimes there is nothing in $sth and I get the following error: DBD::Sybase::st fetchall_hashref failed: Field 'ent_id' does not exist (not one of COL(1)) at /.../.../myscript line 75. As I do error checking, it looks like it just doesn't create an error. As is is a Select statement, I also cannot use the $sth->rows to check if there are any rows.

Any wisdom greatly appreciated!

Thanks, Sven

In reply to DBI::Sybase sometimes returns nothing, but does not generate an error -> how can I catch this? by svenXY
