What are all the types of SQL injection?
SQL Injection can be classified into three major categories – In-band SQLi, Inferential SQLi and Out-of-band SQLi.
Injection is involved in four prevalent attack types: OGNL injection, Expression Language Injection, command injection, and SQL injection. During an injection attack, untrusted inputs or unauthorized code are “injected” into a program and interpreted as part of a query or command.
In-band SQL injection is the most frequent and commonly used SQL injection attack. The transfer of data used in in-band attacks can either be done through error messages on the web or by using the UNION operator in SQL statements.
SQL has three main components: the Data Manipulation Language (DML), the Data Definition Language (DDL), and the Data Control Language (DCL).
There are 3 main types of commands. DDL (Data Definition Language) commands, DML (Data Manipulation Language) commands, and DCL (Data Control Language) commands.
The three main routes are intradermal (ID) injection, subcutaneous (SC) injection and intramuscular (IM) injection. Each type targets a different skin layer: Subcutaneous injections are administered in the fat layer, underneath the skin. Intramuscular injections are delivered into the muscle.

A SQL injection is a technique that attackers use to gain unauthorized access to a web application database by adding a string of malicious code to a database query. A SQL injection (SQLi) manipulates SQL code to provide access to protected resources, such as sensitive data, or execute malicious SQL statements.
How are SQL injection attacks done?
To make an SQL Injection attack, an attacker must first find vulnerable user inputs within the web page or web application. A web page or web application that has an SQL Injection vulnerability uses such user input directly in an SQL query. The attacker can create input content.
- DDL – Data Definition Language.
- DQL – Data Query Language.
- DML – Data Manipulation Language.
- DCL – Data Control Language.
- TCL – Transaction Control Language.
The scope of SQL includes data query, data manipulation (insert, update, and delete), data definition (schema creation and modification), and data access control.
There are six types of SQL operators that we are going to cover: Arithmetic, Bitwise, Comparison, Compound, Logical and String.
- CONSTRAINT clause.
- FOR UPDATE clause.
- FROM clause.
- GROUP BY clause.
- HAVING clause.
- ORDER BY clause.
- The result offset and fetch first clauses.
- USING clause.
Three primary components make up SQL Server architecture: Protocol Layer, Relational Engine, and Storage Engine.
Five types of SQL queries are 1) Data Definition Language (DDL) 2) Data Manipulation Language (DML) 3) Data Control Language(DCL) 4) Transaction Control Language(TCL) and, 5) Data Query Language (DQL)

What are the 4 injection sites?
There are four sites on your body that can be used to give yourself an intramuscular injection. These include the upper arm, thigh, hip, and buttocks.
There are three types of dependency injection — constructor injection, method injection, and property injection.
The most commonly injected drug is heroin, but amphetamines, buprenorphine, benzodiazepines, barbiturates, cocaine, and methamphetamine also are injected. Treatment of PWID may be complicated by social and political barriers to treatment and by a lack of resources for public health approaches to treatment.
SQL injection (SQLi) is a cyberattack that injects malicious SQL code into an application, allowing the attacker to view or modify a database. According to the Open Web Application Security Project, injection attacks, which include SQL injections, were the third most serious web application security risk in 2021.
Active and Passive attacks in Information Security - GeeksforGeeks.
In the first order injection, the attacker enters a malicious string and commands it to be executed immediately. In the second order injection attack, the attacker inputs a malicious string that is rather resistant and stealthy. This string is executed when a trigger activity is realized.
SQL Injection (SQLi) is the most common attack vector accounting for over 50% of all web application attacks nowadays. It is a web security vulnerability that exploits insecure SQL code. Using that, an attacker can interfere with the queries an application makes to its database.
In a Second Order SQL Injection, the malicious user-supplied injected input is stored in the Database and later it is used (without proper sanitization) in a new SQL query when a user accesses some other functionality of the same application. This is what is called a Second Order SQL Injection.
An SQL injection attack uses malicious SQL code for backend database manipulation to access private information. This information may include sensitive company data, user lists or customer details. SQL stands for 'structured query language' and SQL injection is sometimes abbreviated to SQLi.
The single quote (') is the most common character used for SQL injection attacks.
What are three ways to mitigate SQL injection threats?
- Option 1: Use of Prepared Statements (with Parameterized Queries)
- Option 2: Use of Properly Constructed Stored Procedures.
- Option 3: Allow-list Input Validation.
- Option 4: Escaping All User Supplied Input.
The three root causes of SQL injection vulnerabilities are the combining of data and code in dynamic SQL statement, error revealation, and the insufficient input validation.
- Data Query Language (DQL Commands in SQL)

Commonly used DDL in SQL querying are CREATE, ALTER, DROP, and TRUNCATE.
- NOT NULL - Ensures that a column cannot have a NULL value.
- UNIQUE - Ensures that all values in a column are different.
- PRIMARY KEY - A combination of a NOT NULL and UNIQUE . ...
- FOREIGN KEY - Prevents actions that would destroy links between tables.
Operators are widely used for adding two numbers to assign value to a variable. The different types of operators are arithmetic operators, assignment operators, comparison operators, logical operators, identity operators, membership operators, and boolean operators.
- In-band SQLi. The attacker uses the same channel of communication to launch their attacks and to gather their results. ...
- Inferential (Blind) SQLi. ...
- Out-of-band SQLi.
- Data Definition Language (DDL) Statements.
- Data Manipulation Language (DML) Statements.
- Transaction Control Statements.
- Session Control Statements.
- System Control Statement.
- Embedded SQL Statements.
Types of SQL Commands. There are five types of SQL commands: DDL, DML, DCL, TCL, and DQL.
What are the 4 types of SQL JOIN operations?

In MySQL there are three main data types: string, numeric, and date and time.
There are two types of SQL functions, aggregate functions, and scalar(non-aggregate) functions. Aggregate functions operate on many records and produce a summary, works with GROUP BY whereas non-aggregate functions operate on each record independently.
SQL statements are divided into two major categories: data definition language (DDL) and data manipulation language (DML).
