handling null values

[shaan1980]

I need some help with handling null values in the database using perl.
My query say returns 8 records
If certain attributes are missing how do i handle it in the program

Perl considers a variable to be True if it has any assigned value (besides 0). So, for example:

if ($variable) { print "I have a value."; }
else { print "Variable not defined." }

Is that what you're looking for?

[DrDoc]

if(defined($variable)) {

}
