What are prepared statements in SQL?

Prepared statements are precompiled SQL statements that can be executed multiple times with different parameters.

Can you give me an example of a prepared statement?

Sure! Here's an example in Python using SQLite:

import sqlite3

conn = sqlite3.connect('example.db')
c = conn.cursor()

# Create a prepared statement
stmt = "INSERT INTO users (name, age) VALUES (?, ?)"

# Execute the prepared statement with parameters
c.execute(stmt, ('Alice', 30))
conn.commit()

What are the benefits of using prepared statements?

They help prevent SQL injection, improve performance, and make code cleaner by separating SQL logic from data.
