Iterate MySQL records and create a JSON in GoLang

I'm trying to read data from a MySQL database from my Go app. var queryStr string = "SELECT * FROM Customers" rows, err := db.Query(queryStr) defer rows.Close() for rows.Next() { // do stuffs } The query it's ok and it works; now I'd like to easily map each record of the MySQL query to a Customer object that I've previuosly defined as showed below: type Customer struct { id IntegerType `json:"id"` name string `json:"name"` surname string `json:"surname"` } How can I do that? Second question: once I get an array of Customer object how can I easily put it into a new JSON object under a specific key called "data"? thanks for your support :)
