Re: Syntax question when using Class::DBI

That's perfectly valid syntax (although more paranoid code would check with UNIVERSAL::can before calling arbitrary methods).

freebie:~ 973> cat fooble                                             
+ 19:55:47
my $columnname = 'id';
print $rowobj->$columnname;
freebie:~ 974> perl -wc fooble                                        
+ 19:55:48
Name "main::rowobj" used only once: possible typo at fooble line 2.
fooble syntax OK

Your problem's elsewhere.

fooble syntax OK Your problem's elsewhere. Scratches head ... Really, I'm not crazy: `gonzo:: more foo.pl #!/usr/local/bin/perl my $columnname = 'id'; print $rowobj->$columnname; gonzo:: perl -c foo.pl syntax error at foo.pl line 4, near "$columnname;" foo.pl had compilation errors.` [download] OK, how about that fact that I'm running an ancient perl 5.005. That would explain our different results. And the solution for 5.005 is staring at me in another NOOBs question: `my $columnname = 'id'; print $rowobj->{$columnname};` [download] Cheers ------------------------------------- Nothing is too wonderful to be true -- Michael Faraday	[reply] [d/l] [select]

Be aware that Class::DBI lazy-loads the columns, so as soon as you start using the `Essential` feature for columns, you might find `$rowobj->{$columnname}` empty even though there is a value in the column. Using the `get` method should make sure that your object gets filled with data.	[reply] [d/l]
