Additional Notes
Why should you avoid concatenating user input into SQL queries?
Track: Java
Topic: SQL for Java Devs
Focus: PreparedStatements
Java: PreparedStatements
Answer
It opens up security vulnerabilities to SQL injection.
Concatenating user input directly into SQL queries allows malicious actors to inject harmful SQL code, potentially compromising the database. PreparedStatements eliminate this risk by separating query logic from user input. For example, using `"SELECT * FROM users WHERE username = '" + userInput + "'"` is risky.
