Tables

In relational database systems (DBS) data are represented using tables (relations). A query issued against the DBS also results in a table.

A table is uniquely identified by its name and consists of rows that contain the stored information, each row containing exactly one tuple (or record ). A table can have one or more columns. A column is made up of a column name and a data type, and it describes an attribute of the tuples. The structure of a table, also called relation schema, thus is defined by its attributes. The type of information to be stored in a table is defined by the data types of the attributes at table creation time.

SQL injection is yet another common vulnerability that is the result of lax input validation. Unlike cross-site scripting vulnerabilities that are ultimately directed at your site’s visitors, SQL injection is an attack on the site itself—in particular its database.

The goal of SQL injection is to insert arbitrary data, most often a database query, into a string that’s eventually executed by the database. The insidious query may attempt any number of actions, from retrieving alternate data, to modifying or removing information from the database.

To demonstrate the problem, consider this excerpt:
// supposed input
$name = “ilia’; DELETE FROM users;”;
mysql_query(“SELECT * FROM users WHERE name=’{$name}’”);

The function call is supposed to retrieve a record from the users table where the name column matches the name specified by the user. Under normal circumstances, $name would only contain alphanumeric characters and perhaps spaces, such as the string ilia. But here, by appending an entirely new query to $name, the call to the database turns into disaster: the injected DELETE query removes all records from users.
