What are the best practices for using SELECT in Go?

When using SELECT in Go, it's important to consider the following best practices: 1. Use prepared statements to prevent SQL injection. 2. Always handle errors properly. 3. Limit the number of rows returned to improve performance. 4. Use context for timeouts and cancellations.

Can you explain why prepared statements are important?

Prepared statements are crucial because they help prevent SQL injection attacks by separating SQL logic from data. This means user input is treated as data, not executable code.

What is the role of context in SELECT queries?

Context in SELECT queries allows you to manage timeouts and cancellations effectively. It helps in controlling the execution of queries, especially in long-running operations.

How can I limit the number of rows returned?

You can limit the number of rows returned by using the LIMIT clause in your SQL query. For example, SELECT * FROM users LIMIT 10; will return only the first 10 rows.

Any tips for handling errors in Go?

Always check for errors after executing a query. Use the if err != nil pattern to handle errors gracefully and log them for debugging.
