How Can Parameterized Queries Prevent SQL Injection in MySQL?

Avoiding SQL Injection Attacks with Parameterized Queries in MySQL

In MySQL, it's essential to employ parameterized queries when inserting data to avoid security vulnerabilities. String interpolation, as exemplified in the provided code snippet, is prone to SQL injection attacks as it does not adequately escape input parameters.

The correct syntax for parameterized queries in MySQL using the MySQLdb module is as follows:

cursor.execute ("""
    INSERT INTO Songs (SongName, SongArtist, SongAlbum, SongGenre, SongLength, SongLocation)
    VALUES
        (%s, %s, %s, %s, %s, %s)

""", (var1, var2, var3, var4, var5, var6))

In this syntax, placeholders (%s) are used in place of variable values. The tuple (var1, var2, ..., var6) contains the actual values to be inserted.

By employing parameterized queries, you ensure the proper escaping of all input parameters, preventing malicious actors from injecting harmful SQL code into your database and exploiting potential vulnerabilities.
