How do I handle database connections in Go?

In Go, you can use the database/sql package to manage database connections. You typically start by opening a connection using sql.Open().

What should I do to ensure connections are properly closed?

You should always defer the Close() method on your database connection right after opening it. This ensures it gets closed when the function exits.

How can I handle connection pooling?

Go's database/sql package automatically manages connection pooling for you. You can configure the maximum number of open and idle connections using SetMaxOpenConns() and SetMaxIdleConns().

Is there a way to handle errors when connecting?

Yes, always check for errors after calling sql.Open() and handle them appropriately to avoid runtime issues.
