Here is a library just for that: scany.

You can use it like that:

type User struct {
    Name  string
    Id    int
    Score int
}

// db is your *sql.DB instance
// ctx is your current context.Context instance

// Use sqlscan.Select to query multiple records.
var users []*User
sqlscan.Select(ctx, db, &users, `SELECT name, id, score FROM users`)

// Use sqlscan.Get to query exactly one record.
var user User
sqlscan.Get(ctx, db, &user, `SELECT name, id, score FROM users WHERE id=123`)

It's well documented and easy to work with.
