Understanding SQL Injection: SQL injection is a common attack where malicious SQL code is inserted into user inputs, potentially leading to unauthorized access or manipulation of a database. Understanding the risks is the first step in prevention. Preventive Measures: Protecting against SQL injection involves adopting secure coding practices and leveraging features provided by database management

INNER JOIN The INNER JOIN operation is fundamental in SQL, combining rows from two or more tables based on a related column. Consider the following: Syntax: Example: Suppose you have a ‘Customers’ table and an ‘Orders’ table. An INNER JOIN retrieves rows where there is a match in the ‘CustomerID’ column: LEFT JOIN / RIGHT
