Re^3: Mysql and Perl Module by Anonymous Monk on Jun 14, 2012 at 09:33 UTC
Hello, I don't understand the meaning of %s ? Is this a hash ? No, its a string, a format string If you use `perl -MO=B::Deparse,-p myfile.pl` to see how perl parses my code, you can see how that format string is the first argument to the sprintf function I'm getting my information from an array. My problem is I don't know how many columns I'm getting. You don't need to know, the array/code I posted knows that information, and does the right thing -- I linked a runnable example ( Re: Open multiple file handles? ) a few minutes ago in Re^3: Mysql and Perl Module	[reply]

Thank you Monk :-) I'm trying at the moment to adapt your example on my requirements. This is very helpful.	[reply]

in sprintf, %s is a placeholder for a string, as in: `$a = "world"; sprintf "hello %s", $a; # results in "hello world"` [download]	[reply] [d/l]
