Subject: Perl Issues
Our Developers wrote our Special Ed Student Info. application in Perl -
about which I know zip. Without going into gory details of why, their
code repeatedly checks for the existence of specific tables (out of the
150,000+ tables in our Production Student Info.) by doing
"Select Count(*) From All_Tables Where Table_Name = '<TableName>'"
whick is very inefficient, especially with 150,000 tables.
First of all, I want them to not check for table existence and code in
Exception Handling, but they are resistent to my suggestions.
Second, if they don't code the Exception Handling, I want them to use a
utility function that we have that more efficiently checks for table
existence and returns a Boolean - True if exists, False if not exists.
My two questions:
1. Can Exception Handling be easily done in Perl? If so, any good
examples I can point them to?
2. They say that Perl can't handle Boolean values. Is that true? Any
guidance here?
Thanks.
