The prepare() failed and you haven't the foggiest notion of what
happened since you aren't checking for errors. You should either set
$dbHandle -> {RaiseError} or check for errors on each method call.
# Either enable implicit error checking
$dbHandle -> {RaiseError} = 1;
# Or check for errors each method call
my $sqlSch = "SELECT SEQ_NO from $TableName";
my $sth = $dbHandle->prepare($sqlSch)
or die "Prepare failed, $DBI::errstr\n$sqlSch\n";
$sth->execute() or die "Execute failed, $DBI::errstr\n";
