Answer 1

我是在"pascal"的帮助下完成的.

查询变为:

SELECT
    * 
FROM
    (
        SELECT 
            temperature,
            climate,
            temperatureTime,
            photoURL,
            (((latitude - 37.331689) * (latitude - 37.331689)) + (longitude - (-122.030731)) * (longitude - (-122.030731))) * (110 * 110) AS dist 
        FROM 
            weather
    )
    AS tab 
WHERE 
    tab.dist <= (1.0 * 1.0); 

此查询用于查找1公里范围内最近的位置坐标.
