How do I manage database connections in Go using the SQL driver?

To manage database connections in Go, you can use the database/sql package along with a driver like go-sql-driver/mysql. You should open a connection pool and handle connections efficiently.

What are the best practices for connection pooling?

Best practices include setting a maximum number of open connections, using db.SetMaxOpenConns(n) and db.SetMaxIdleConns(n), and ensuring connections are closed properly.

How can I handle connection errors?

You can handle connection errors by checking the error returned from db.Ping() or when executing queries. Implement retries or fallback mechanisms as needed.

Is there a way to monitor the connection pool?

Yes, you can monitor the connection pool by using the Stats() method on the database object, which provides information about the current state of the pool.
