A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
An SQL injection takes advantage of SQL syntax to inject malicious commands that can read or modify a database or compromise the meaning of the original query. [13] For example, consider a web page that has two text fields which allow users to enter a username and a password.
SQL injection and similar attacks manipulate database queries to gain unauthorized access to data. [30] Command injection is a form of code injection where the attacker places the malware in data fields or processes. The attacker might be able to take over the entire server. [30]
A file inclusion vulnerability is a type of web vulnerability that is most commonly found to affect web applications that rely on a scripting run time.This issue is caused when an application builds a path to executable code using an attacker-controlled variable in a way that allows the attacker to control which file is executed at run time.
SQL Injections. SQL injection is a code injection technique used by threat actors to attack any data-driven applications. Threat actors can inject malicious SQL statements. This allows threat actors to extract, alter, or delete victim's information. [20] Denial of Service Attacks
efficiency, because they can be used repeatedly without re-compiling; security, by reducing or eliminating SQL injection attacks; A prepared statement takes the form of a pre-compiled template into which constant values are substituted during each execution, and typically use SQL DML statements such as INSERT, SELECT, or UPDATE.

One technique for evaluating database security involves performing vulnerability assessments or penetration tests against the database. Testers attempt to find security vulnerabilities that could be used to defeat or bypass security controls, break into the database, compromise the system etc. Database administrators or information security administrators may for example use automated ...
