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 example of how you can see code injection first-hand is to use your browser's developer tools. Code injection vulnerabilities are recorded by the National Institute of Standards and Technology (NIST) in the National Vulnerability Database as CWE-94. Code injection peaked in 2008 at 5.66% as a percentage of all recorded vulnerabilities. [4]
The financial sector last year, after relinquishing the top spot in 2022, once again was the industry to suffer the most data breaches, according to a report by Kroll, the financial and risk ...
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
In Oracle SQL, most operations and searches are case-sensitive by default, [6] while in most other DBMSes, SQL searches are case-insensitive by default. [ 7 ] Case-insensitive operations are sometimes said to fold case , from the idea of folding the character code table so that upper- and lowercase letters coincide.
Program monitoring records and logs different kinds of information about the program such as resource usage, events, and interactions, so that it can be reviewed to find or pinpoint causes of abnormal behavior. Furthermore, it can be used to perform security audits. Automated monitoring of programs is sometimes referred to as runtime verification.

In SQL:1999 a recursive (CTE) query may appear anywhere a query is allowed. It's possible, for example, to name the result using CREATE [ RECURSIVE ] VIEW . [ 16 ] Using a CTE inside an INSERT INTO , one can populate a table with data generated from a recursive query; random data generation is possible using this technique without using any ...
