How would InnoDB handle this query?

DarkLight — Tue, 22 Aug 2017 09:20:58 +0000

Hi guys.
Not a high priority question, as the following is used only occasionally and the function it is a part of is an Admin Lookup tool, so spamming the DB with it is out of the question.

I was wondering if, when your specify multiple conditions in WHERE and give it a LIMIT 1, would the query continue to go through each and every WHERE condition, or would it stop and return the result the first time it finds a match?

For example:

<?php
$query = mysqli_query($GLOBALS['dblink'], "SELECT * FROM users LEFT JOIN online ON OnlineUID = UserID WHERE UserID = '$info' OR UserIP = '$info' OR OnlineIP = '$info' OR UserEmail = '$info' OR UserName LIKE '%$info%' LIMIT 1");
?>

This, as you can see, is a TERRIBLE query, and normally wouldn't come anywhere near my site. But in this instance, it's actually very effective at doing its job.

BUT, if say, it matched the UserID and was able to return a result, would it then continue to look through UserIP, UserEmail and UserName, just because it's in the query? or would it stop searching once it matched UserID?

Because I've tried to set up the query in such a way that if the latter is true, it would be relatively efficient as the WHERE fields are positioned from Most to Least ideal in terms of Indexes. The last one (UserName) being by far the worst.

Hope that all makes sense, and hopefully someone can enlighten me

Thanks in advance.

Do I need a database?

ansvdb — Sun, 12 Jun 2016 01:02:38 +0000

We have a website with more than 5000 pictures and growing. When our members want to view the site pages, the pages are loading very slow. Each page has 10 to 60 pictures. We are a fully volunteer organization. Someone suggested that by using a database the pages will load a lot faster. Do we need a database? And how to create one? We do not have a tech in our volunteer, yet. Any help would be greatly appreciated.

<html>
<head><title>Testing Sessions page 1</title></head>
<body>
<?php
$_SESSION['session_var'] = "testing";
@$_SESSION['session_var2'] = $_POST['email'];
echo "This is a test of the sessions feature.
<form action='sessionTest2.php' method='POST'>
<input type='hidden' name='form_var'
value='testing'>

Linking a login form on HTML page to MySQL Database hosted locally on the same domain

syntactix — Sun, 14 Apr 2013 07:17:25 +0000

Hello. I am a new HTML5 web developer based in South Africa. I have used the old HTML for a very long time but found it to be kind of limiting in places, then I moved over to Joomla which I found a lot easier and quicker to design with, but the problem with this is it is also limiting as to what can go where.. I used Artisteer to design my Joomla websites in and then always had major issues getting everything to show where it was supposed to.

So then I recently decided to move away from Joomla, and try something like HTML5 which is new and apparently quite powerful and easy to use. I am still designing all my websites in Artisteer as this has an export function to HTML5, although everything designed shows where it is supposed to after exported, I am still completely in the dark as to the code involved to get my Login Form / Registration Form linked to a MySql database, like it used to work on Joomla..

Is there anyone on this forum that would be able to assist me with this please?
Basically what I want to do is:

Take the login form that is shown on the attached picture, and link it to a MySQL Database so that users can register their details into our Database for future mass mailing.

P.S. The new website is designed in HTML5 not Joomla.

is there an easy way to update a website without going into the source everytime?

hellrazer21 — Fri, 15 Feb 2013 00:31:25 +0000

i posted this topic under webmaster's corner

http://www.webmaster-forums.net/webmasters-corner/there-easy-way-update-website-without-going-source-everytime

but now im thinking this might have to do with database programming

since i need to have a way to update the site without haveing to change every individual page

like if i want to update the look of one page that needs to be the same for alot of pages on the site

maybe it would be easier to call up the information that needs to be displayed i think that might have to do with a data base but im not sure

NoSQL and Web Hosting

gracemcadams — Fri, 25 Jan 2013 19:47:00 +0000

Hey webmasters

I've started a survey website and several friends of mine suggested that I take a NoSQL DB approach since my traffic is starting to pick up and I need to be able to call things more quickly. Do any of you know of any/if any of the popular web hosts offer an easy NoSQL solution? Otherwise, any tips on converting my current relational DB to a NoSQL DB?

Thanks!

Inserting data into multiple tables in MySQL using PHP

miramirae — Sun, 30 Sep 2012 09:53:33 +0000

Hi,

I have a form whereby when user clicks "submit" the data filled inside the field will be stored inside 2 tables. all of the fields will be saved inside studentDetails table while only some of it will be saved inside another table, called KPP table.

Below is a fraction of my codes. Am i doing it right? Thanks in advance..

$sql="INSERT INTO $studentDetails VALUES ('$IC','$name','$sex','$address','$phonenum1','$phonenum2','$type','$date','$deposit','$totalFee')";
$result=mysql_query($sql,$conn);

$sql2="INSERT INTO $kpp(ICnum,licenseType,dateRegistered,totalFee,remainingAmount) VALUES ('$IC','$type','$date','$totalFee','$answer')";
$result2=mysql_query($sql2,$conn);

if($result && $result2){
printf("window.alert (\"New record added!\");");
include "AddNewRecord.html";
}
else {
echo "Error: " . mysql_error()."";
}

Why input data cannot save into database?

What is the most efficient way of doing this...

DarkLight — Mon, 06 Feb 2012 22:02:18 +0000

Hi guys, it's been a while since my last question. But now I'm stuck, so here I am

I have a database (MySQL) with a table containing millions of rows.
I read/write to this table upto 100 times per minute at peek-time.

I was contacted by my hosting company, and told that I didn't have enough power on my shared-host, and needed a VPS.

Well the time has long since came when I needed a VPS, so I intend to update very soon. But here's what I wanna do. I want to let my site grow, and not worry about the queries on the large table. I need to know if there are any other tables that would be faster/more efficient with the same capabilities of MySQL.

I've thought about InnoDB, but not knowing if it would be beneficial, I never went with it...

Just incase it means anything, here's the most commong query on that table...

<?php
$query = mysql_query("SELECT * FROM songs WHERE SongName LIKE '%$terms%' ORDER BY Popularity DESC LIMIT 30");
?>

Any help here would be appreciated, as this sort of stuff isn't my strongpoint.

UPDATED: I changed "%$terms%" to "$terms" to remove the wildcard, would this matter that much and was it a good move? Or will queries be fine with this?

NOABL - UK Wind Speed Database

stormie — Wed, 31 Aug 2011 21:30:06 +0000

Hi Guys,

I have an interesting problem if anyone fancies a shot at it.
This database was built in the 1980's and has; I'm guessing about 10'000 entries. I need to make a simple app for a wind prospector to search the database and retrieve the locations of high wind-speeds.

It is built on the back of the Ordnance Survey 6 digit locations (SS7456 for example) a full OS ref has 8 digits of course.

My question/challenge is how should I re-work this data to make it suitable for a modern web script to access?

My initial thought was to trudge through marking it up with xml tags between each string set and then parse the strings with java-script or something but even that will take ages! any suggestions will be greatly appreciated.

managing web form data

nerodha — Thu, 30 Jun 2011 19:46:23 +0000

hi everyone,

this is my first post and i'm glad to be part of the community

i'm new to web development, so i'm looking for some general pointers/ideas that will help get me closer to a solution. here's what i need:

- a web form that allows users to upload files (mostly Word files and PDFs)
- a database that'll store the form data and associated files
- a way (as automatic as possible) of saving all of the form data submitted over time into a single excel spreadsheet

a couple issues i realize i have to address are validation (client- and server-side) and security. i'd appreciate any suggestions on resources/scripting languages/already existing open-source alternatives that will help me achieve this. please let me know if you need more specifics and thanks in advance!!!

Quick SQL help!

RevillWebDesign — Wed, 15 Jun 2011 09:47:59 +0000

Hi All,

Need some quick SQL help. Details are as follows:

I have 4 tables:

businesses [Holds business info]
loc_link [links businesses to a location]
cat_link [links businesses to a category]
reviews [holds reviews for businesses]

I have a query:

SELECT * FROM businesses, loc_link, cat_link WHERE loc_link.loc_id = '$loc_id' AND loc_link.business_id = businesses.id AND cat_link.cat_id = '$cat_id' AND cat_link.business_id = businesses.id AND businesses.active = 'true'

What I need to do on the fly is check how many reviews the businesses have and then ORDER BY amount of reviews.

Is it possible to do something like mysql_num_rows() within an SQL query?

Any help would be greatly appreciated.

Thanks.
