I am using DBI & MySQL to develop my own database driven website and have the following question on strategies:

Suppose I have a query that returns more lines of data than I want to send in a single web page, the data may be from a single or multiple tables, and it may contain only some of the entries from a given table or all of them.

What are some ways of:

A - Keeping track of where I am in displaying the results and either pass that info through a parameter in a "next" link on the web page or store the info in a state file?

B - Storing the data either in the database (is it possible to just ask the db for a range of results without incurring the cost of getting the entire result set?) or in a temporary file of some sort (and what is the best way of cleaning that up)?

Any ideas on what is the most efficient in terms of memory, processing time, disk usage, etc. would be greatly appreciated!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
