SQL SELECT Commands


1. Login in to the mysql client using the login name and password provided by your instructor (if
not already logged in).

2. In the photo_album databases, load the /tmp/photo_album.sql.data file into the
database.

USE photo_album;
SOURCE /tmp/photo_album.sql;

3. Perform an aggregate select against each table to count the number of records located in each
table.

SELECT COUNT(*) FROM customers;
SELECT COUNT(*) FROM comments;
SELECT COUNT(*) FROM images;
SELECT COUNT(*) FROM logins;

4. Using the customers table, list the customers who are active from closest to farthest
termination date (term_date).

SELECT * FROM customers WHERE active_customer='True' ORDER BY
term_date ASC;

5. Using the logins table, list those with active logins and have logged in during the month of
April 2007.

SELECT * FROM logins WHERE active_login='True' && last_login
LIKE '2007-04%';

6. Using the images table, list the active images names from the most recent date to the oldest
dates (image_date).

SELECT file_name, image_date FROM images WHERE active_image
ORDER BY image_date DESC;

7. Using the comments table, list the user with the most active comments.

SELECT login_name, COUNT(*) FROM comments WHERE active_comment =
'True' GROUP BY login_name DESC;

PHP INTRODUCTION

                     PHP  (recursive acronym for  PHP: Hypertext Preprocessor ) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. PHP stands for  P HP:  H ypertext  P reprocessor PHP is a server-side scripting language, like ASP PHP scripts are executed on the server PHP supports many databases (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, Generic ODBC, etc.) PHP is an open source software PHP is free to download and use Why PHP? PHP runs on different platforms (Windows, Linux, Unix, etc.) PHP is compatible with almost all servers used today (Apache, IIS, etc.) PHP is FREE to download from the official PHP resource:  www.php.net PHP is easy to learn and runs efficiently on the server side What can PHP do? Anything. PHP is mainly focused on server-side scripting, so you can...

Data Encryption

Data encryption is the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. The intended recipient can then decode (or decrypt) the information. PHP offers multiple means to make this happen. However, none of these solutions are very effective without the applications running on secure servers and connections. The following are a list of the more common encryption functions in PHP: • md5() - MD5 is a third-party hash algorithm that PHP can use to create a digital fingerprint of a piece of data. It is next to impossible to (efficiently) recover the original text when a piece of data has been encrypted with the md5 hash algorithm. It is also vastly unlikely that any different text string will create an identical hash - a 'hash collision'. These properties make hashes ideally suited for storing an application's passwords because although an attacker may compromise a part of the system...

Delimiting PHP Code

                           PHP was originally designed to be used in conjunction with a web server, and in the case of the LAMP architecture, the Apache Web Server.  PHP applications are designed embedding PHP scripts within a web page along with its HTML.  Unlike standard HTML pages which are sent directly from the web server to the end user, PHP files are first interpreted by the PHP application which then converts the PHP script into another form for display.  This process eliminates the end user from being able to see the original PHP script that was embedded in the HTML and provides  true interaction in HTML files.  This process is similar to proprietary applications such as ASP and Coldfusion; however, PHP is Open Source and cross- platform. PHP Tags             PHP scripts are distinguished from the HTML scripts by using delimiting characters ...
