type User struct { Id int64 Name string Email string } func GetUserById(db *gorp.DbMap, id int64) (*User, error) { user := new(User) err := db.SelectOne(user, "SELECT * FROM Users WHERE id = ?", id) if err != nil { return nil, err } return user, nil } func main() { db, err := sql.Open("mysql", "user:password@/dbname") if err != nil { log.Fatal(err) } defer db.Close() dbmap := &gorp.DbMap{Db: db, Dialect: gorp.MySQLDialect{}} user, err := GetUserById(dbmap, 1) if err != nil { log.Fatal(err) } fmt.Println(user) }This code defines a User struct, a function that retrieves a single user from the database based on the user ID, and a main function that demonstrates how to use gorp.SqlExecutor Get to retrieve and print the user information.
