		Build()
	fmt.Println(sqlw.Debug(q, args...))

resultat:

insert into users(email,phone,age) values(abc@example.com,nullif(+7939739473,''),coalesce(29,age)) returning id

	// update
	q, args = sqlw.Update("users").
		Set("email", user.Email).
		Set("phone", sqlw.Nullif(user.Phone, "''")).

	fmt.Println(sqlw.Debug(q, args...))

resultat:

update users set email=abc@example.com,phone=nullif(+7939739473,''),age=coalesce(29,age),role=coalesce(nullif(,''),role) returning updated_at where id = 3
