See also: Where in the documentation does it say that while tests readdir for definedness?. (Not a duplicate; just closely related.) Many people treat the loop below as idiomatic: while (defined(my $file = readdir($dir)) { ... } instead of: while (my $file = readdir($dir)) { ... } because supposedly with the latter vers...

Can I use a MySQL function or procedure to return table names that can be used in a query? Something like SELECT * FROM get_db_table_name(2342352412); where get_db_table_name() is a user defined function which accepts a user_id as a parameter and returns the db.table where that user resides. I have not been able to do this this way be...
How do you know whether a variable has been set at a particular place in the code at runtime? This is not always obvious because (1) the variable could be conditionally set, and (2) the variable could be conditionally deleted. I'm looking for something like defined() in Perl or isset() in PHP. if condition: a = 42 # is a defined he...

I need to determine if a Perl hash has a given key, but that key will be mapped to an undef value. Specifically, the motivation for this is seeing if boolean flags while using getopt() with a hash reference passed into it. I've already searched both this site and google, and exists() and defined() don't seem to be applicable for the si...

I recently asked the question http://stackoverflow.com/questions/2380803/is-the-behavior-of-return-x-defined The result was about what I expected, but got me thinking about a similar situation. If I were to write class Foo { ... int x; int& bar() { return x++; } }; Where bar now returns an int reference, is this behav...

I made a Visual Studio project to compile the .cs into a dll having namespace CalculatorService (CalculatorService.dll). Successful thus far. I created an asp.net project added my namespace import: %@ Import Namespace="CalculatorService" % ...
I need to validate a Perl hash of hash element such as $Table{$key1}{$key2} to exist and be defined. Here is what I do. (I have no idea $key1 even exists) if ((defined $Table{$key1}) && (exists $Table{$key1}) && (defined $Table{$key1}{$key2}) && (exists $Table{$key1}{$key2})) { #do whatever } Is there an easier and cleaner w...
What's the most concise way to determine if @hash[:key1][:key2] is defined, that does not throw an error if @hash or @hash[:key1] are nil? defined?(@hash[:key1][:key2]) returns True if @hash[:key1] exists (it does not determine whether :key2 is defined) ...
