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).
The two claimed that the attack was allowed due to a simple mistake by the web-developers and the attack was indeed SQL Injection. [6] The group released the first in what is supposed to be a series of mini e-zines under the operation of "FuckTheSystem" on September 28, 2012.
Data cleansing or data cleaning is the process of identifying and correcting (or removing) corrupt, inaccurate, or irrelevant records from a dataset, table, or database. It involves detecting incomplete, incorrect, or inaccurate parts of the data and then replacing, modifying, or deleting the affected data. [ 1 ]

Major DBMSs, including SQLite, [5] MySQL, [6] Oracle, [7] IBM Db2, [8] Microsoft SQL Server [9] and PostgreSQL [10] support prepared statements. Prepared statements are normally executed through a non-SQL binary protocol for efficiency and protection from SQL injection, but with some DBMSs such as MySQL prepared statements are also available using a SQL syntax for debugging purposes.
Code injection is a class of computer security exploits in which vulnerable computer programs or system processes fail to correctly handle external data, such as user input, leading to the program misinterpreting the data as a command that should be executed. An attacker using this method "injects" code into the program while it is running.
DELETE requires a shared table lock; Triggers fire; DELETE can be used in the case of: database link; DELETE returns the number of records deleted; Transaction log - DELETE needs to read records, check constraints, update block, update indexes, and generate redo / undo. All of this takes time, hence it takes time much longer than with TRUNCATE
Injection exploits are computer exploits that use some input or data entry feature to introduce some kind of data or code that subverts the intended operation of the system. Usually these exploits exploit vulnerabilities resulting from insufficient data validation on input and so forth.
