sql-server-2008 - 如何为 SQL Server 2008 组合这两个空间查询

Question

我有两个查询，一个返回前 10 个最近的位置：

            DECLARE @center GEOGRAPHY

            SET @center = geography::Point(@Latitude, @Longitude, 4326)

            SELECT TOP 10
                [Physical_Address_Street]
                , [Physical_Address_Local]
                , [Physical_Address_State]
                , [Physical_Address_Zip]
                , [Phone_Number]
            FROM Gas_Stations
            WHERE Location_Type = 1
            ORDER BY @center.STDistance(Location) ASC

然后另一个将获得通过的纬度和经度的距离

            SELECT Location.STDistance(geography::Point(51, -2, 4326)) * 0.00062137119 
            FROM [MY_DB].[dbo].[Gas_Station]

这些都查询同一个表，那么我如何将它们组合起来并获得十个点中的每一个的距离？

Answer 1

SELECT  TOP 10
        *,
        geography::Point(51, -2, 4326).STDistance(location) * 0.00062137119
FROM    gas_stations
WHERE   location_type = 1
ORDER BY
        @center.STDistance(location) ASC
