为什么订单函数现在可以在 SQL 中使用窗口函数

Question

SELECT d.location, d.continent, d.date, d.population, v.new_vaccinations,
SUM(CONVERT(int, v.new_vaccinations)) OVER (PARTITION BY d.location ORDER BY d.location,d.date) AS       rolling_total_vaccinations
FROM PortofolioProject..coviddeaths d
JOIN PortofolioProject..covidvaccinations v
ON d.location = v.location AND d.date = v.date
WHERE d.continent IS NOT NULL
ORDER BY d.location , d.date

错误说明： 消息 102，级别 15，状态 1，第 85 行 “订单”附近的语法不正确。
