If your variable is sometimes undefined then you can replace it with a
default.
$variable_to_pass = $variable || "Default";
print "$variable_to_pass\n";
$variable = "Now this is set";
$variable_to_pass = $variable || "Default";
print "$variable_to_pass\n";

Subject: Optional Variables
What's the proper syntax to indicate that a variable is optional? The script
that I have created works great when I pass in a variable, but the script
need to execute the SQL even if I don't pass in a variable.
Thanks,
Kim
