Re: [PHP] What is this called?
and throw your favorite Linux distro on it (I'm not touching that holy war with a 10' eth0 cord) I'll touch it. It shouldn't be Fedora - Fedora has too short of a lifetime before major version update is necessary to get patches. The main advantages of Fedora are how new and shiny the desktop is, but a box just for SQL isn't going to care about new and shiny gnome with the pretty widgets. Use RHEL/CentOS for this if you like RPM. Just replace the archaic php 5.1.x and yer good to go ;) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] What is this called?
2009/7/6 Miller, Terion tmil...@springfi.gannett.com: Ok, say you have a database with 16000 records in it, but you only want to call out say 2000 records at a time as the search/query is performed, then store the first 2000 in a session and then retrieve the next 2000 etc etc as a way to minimize server strain? (I'm tasked to do this and ) 1. don't know what this is called to google it...partioning results/data ??? 2. Is there a better way to deal with retrieval of large amounts of data from a large table without choking the server. 3. Is it possible at all Basically I need to know what it is I'm looking to do, it's not getting explained in an understandable way herewhich makes google useless Generally known as paging, and every database server I'm aware of supports it. MySQL for example... select * from table limit page,numrows I would strongly recommend against storing any large dataset in a session since it will likely be as expensive to load it in as it would be to do the database query again. Based on the way you've phrased your question and the 2000 per page I'm guessing you're not doing this for display purposes. If you're wanting to lighten the load on the server while you process the 16,000 rows you might want to look into mysql_unbuffered_query which requires a lot less memory than mysql_query. See the manual for details. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Is there a better way to deal with retrieval of large amounts of data from a large table without choking the server. Well, it depends. You mentioned only that it's a database. Is it an SQL database? If so, what's the engine (MySQL, PostgreSQL, Informix, SQLite, MSSQL, etc.)? If not, what's the format? Also, how frequently will this be called, how large is each row of data (in bytes or kilobytes), and what other things are running on the same server at the same time? Is it a production web server or internal intranet? Is it a shared web server? As you see, there are a ton of other factors and variables involved. ;-P 3. Is it possible at all Absolutely.

It's a paging query that you want to do, but I'd not recommend doing it to store it in a session. You can store all that stuff into a session, but you risk putting a greater load on the users session then you would be putting on the database server. If you are running MySQL, go get a 486, put Fedora on it and use it for the heavy queries.

Boss kept referring to partitioning results By definition, yes, but if you use the term 'partition' in industry terminology - indeed, in SQL commands - you'll wind up with a different result. If you haven't yet come across it, look up 'mysql range partitioning' on Google. -- /Daniel P.

You didn't seriously just tell someone to use an ancient-ass __80486__ PC for their heavy database queries did you? Aside from the fact that machine is like 20 years old and not only would hardware be difficult to find, setup and maintain, it's bound to die at any moment. You're talking ISA (maybe a PCI if you're lucky), IDE drives, slow RAM that probably maxes at 512MB or something... No USB ports, so have fun finding an old mouse/keyboard. A computer with vastly superior technology, reliability and performance can be had for a hundred bucks and probably even free. I just gave away a 1Ghz Celleron the other day that was collecting dust. I wouldn't even use THAT as my database server with hardware as dirt cheap as it is... Dude. Save yourself the headaches and just get a modern, NEW barebones PC: http://www.pricewatch.com/barebones_computers/ http://www.pricewatch.com/computer_systems_no_os/ and throw your favorite Linux distro on it (I'm not touching that holy war with a 10' eth0 cord) Most all distros come with LAMP stacks as an option and you're off and running in about an hour. :D: -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
