Fellow Monasterians,

I'm completely puzzled by behavior I haven't experienced when using placeholders and bind values. It's a though I need to quote values or something. What am I missing after years of successful use?

my $stmt = q/SELECT * FROM users WHERE username= ? AND password = ?/;
my @bind = ( $username, $password ); # doesn't work
my @bind = ( 'wilma', 'foobar' ); # works
my $acct = $dbh->selectrow_hashref($stmt, undef, @bind );

Update: I'm updating this because I don't want anyone who might be new to DBI to stumble across this node and be misled. Turns out, it had something, not sure what, with a dicey connection to our web server. Sounds crazy, but for an hour before a crash, the posted code didn't work with scalars, only hard-coded values. The server went down, and after the reboot, the code worked has it has for years. Sorry to waste previous PM bandwidth on an bizarre anomaly.
