SQL 使用 select 语句添加建表 - 无插入操作

如何解决SQL 使用 select 语句添加建表 - 无插入操作

我需要使用select语句来组成表格

DECLARE @MetresPerMile FLOAT = 1609.344;
DECLARE @LOCStart1 GEOGRAPHY = GEOGRAPHY::Point(48.83000,-97.31000,4326)
DECLARE @LOCDest1 GEOGRAPHY = GEOGRAPHY::Point(48.83000,4326)
DECLARE @LOCStart2 GEOGRAPHY = GEOGRAPHY::Point(22.9230000,-94.5342000,4326)
DECLARE @LOCDest2 GEOGRAPHY = GEOGRAPHY::Point(22.9230000,4326)

SELECT 
    '1' [Start],'1' [Dest],@LOCStart1.Stdistance(@LOCDest1) / @MetresPerMile [distance],'2' [Start],'2' [Dest],@LOCStart2.Stdistance(@LOCDest1) / @MetresPerMile [distance];

我得到的结果是 6 列，我只需要 3 列：

解决方法

这会给你那个结果：

declare @MetresPerMile float = 1609.344;
declare @Points table (Id integer,Point geography);

insert into @Points (Id,Point) 
       values (1,GEOGRAPHY::Point(48.83000,-97.31000,4326)),(2,GEOGRAPHY::Point(22.9230000,-94.5342000,4326));

select Start.Id as Start,Dest.Id as Dest,Start.Point.STDistance(Dest.Point)/@MetresPerMile
from @Points as Start
     cross join @Points as Dest

您可以在点表中添加任意数量的点，选择将返回所有点之间的距离。

感谢 Marc Guillot 的回答，这是否达到了您想要的结果？

declare @MetresPerMile float = 1609.344;

with Points as (
  select *
  from (values
    (1,4326))
  ) pts (Id,Point)
)
select Start.Id as Start,Start.Point.STDistance(Dest.Point)/@MetresPerMile as Distance
from Points as Start
cross join Points as Dest
