I have a script that print test questions and grades them... how do I make
them print a random order, and a certain amount ??
code
@@@@@@@@@@@@@@@@
$dbh =DBI ->connect($data_source, $username, $password) or die "cant connect
to
$data_source : my $dbh-> errstr\n";
my $sth1 = $dbh -> prepare("select * from tests where subject = '$test' ");
$sth1 -> execute or die " unable to execute query ";
#$sth1 -> finish;
