rjsaulakh has asked for the wisdom of the Perl Monks concerning the following question:

I have to design a web page which should display a table consiting of rows . The rows are in large number about 300 and I want to maintain it in database . I want to diplay 15 rows per page , so I would require to break the 300 rows in several no of pages . the no of rows will be dynamic so the numbers of pages will also change depending on the number of rows .

The display functionaltiy should be same to somewhat as in a google . I want to have this database in form of a text file . I want to have hyperlinks on my page which consist of numbers 1 2 3 10 , next and previous button the hyperlinks displayed should change depending on the page I am currently viewing . suppose if I am on page no 7 the hyperlinks to 1 2 3 should hide and pages with hyperlinks as 11 12 13 get diplayed. Please help me what should be my approach and if there any live website which can help me

    Well first off a key part of this is the DataBase you select to use. MySQL has LIMIT which will make you life very easy, other DB's may do it a little differently (or not at all). So I will assume you are using MySQL.
    Now based on your request I am unable to tell your level of scripting proficiency but I get the feeling you are probably new to Perl so here are some good places to start.
    • CPAN The true reason Perl is so powerful. Search for DBI, CGI and HTML::Template to start with
    • MySQL you can search the site for "LIMIT" for example.
    • Ovid's CGI course might be useful as well.
    Just a few hints.
    1. set an offset {what row to start on} and a limit {how many to get each time} in your script and pass them around, each page increment your offset by your limit.
    2. indexes are your friends in MySQL they make searching much more efficient.
    3. make your display a template... do not, I repeat DO NOT start off mixing HTML into your script! HTML::Template is good at helping you aviod this, so read the documentation on CPAN (Others might argue this point with me but I feel it is better to learn good habits early rather than unlearning bad ones eventually)

    I hope that helps point you in the right direction... you may have a lot of reading to do. If you get stuck come on back and ask.

    Well, you could write some Perl which like does that stuff using those module things. And stuff.

    And you should learn how to ask more cogent questions.

    Update: I was going to add a list of links to posts where the OP's been pointed at things like How (Not) To Ask A Question (e.g. CGI perl) numerous times before, but it's not worth it. They didn't learn then, they're not going to now.
