previous writing styles

user := new(User)
err := db.NewSelect().Model(usert). Where("id = ?", 1).Scan(ctx)
// If there is no data that meets the criteria，err = sql.ErrNoRows， user != nil

new feature

var user *User
err := db.NewSelect().Model(&usert). Where("id = ?", 1).Scan(ctx)
If there is no data that meets the criteria，err = nil， user = nil

var users map[string]any
err := db.NewSelect().Model((*User)(nil)). Where("id = ?", 1).Scan(ctx, &users)
If there is no data that meets the criteria，err = nil， users = nil

var phone *string
err := db.NewSelect().Model((*User)(nil)). Where("id = ?", 1).Column("phone").Scan(ctx, &phone)
If there is no data that meets the criteria，err = nil， phone = nil
