How can I handle database errors in Go?

How can I handle database errors in Go?

In Go, you can handle database errors by checking the error returned from your database operations. Always check for errors after executing queries.

Can you give me an example of error handling in a SQL query?

Sure! Here's a simple example:

result, err := db.Exec("INSERT INTO users (name) VALUES (?)", "John")
if err != nil {
    log.Fatalf("Error inserting user: %v", err)
}

What should I do if the error is related to a connection issue?

For connection issues, you can implement retry logic. Use a loop to attempt reconnecting a few times before giving up.

Are there any libraries that can help with error handling?

Yes, libraries like sqlx and gorm provide more advanced error handling and can simplify your database interactions.
