Question

我有以下查询。我想将结果保存在我的临时表中，并在变量中保存isWithInCircle值，这是怎么做的？

declare @source geography = geography::Point(30.221101852485987, 71.575927734375, 4326), @target geography = geography::Point(29.9358952133724, 71.817626953125, 4326);

declare @radius_in_miles int = 100; 

declare @radius_in_meters float = @radius_in_miles * 1081.7316;

select @target.STBuffer(@radius_in_meters).STContains(@source) AS [isWithinCircle],
 @target.STDistance(@source) AS [distance_in_meters],
 @target.STBuffer(@radius_in_meters).STDisjoint(@source) AS [isPastCircle];

基于我对你要做的事情的有限理解，但这应该有用......

IF OBJECT_ID('tempdb..#MyTempTable', 'U') IS NOT NULL DROP TABLE #MyTempTable;

declare @source geography = geography::Point(30.221101852485987, 71.575927734375, 4326), @target geography = geography::Point(29.9358952133724, 71.817626953125, 4326);

declare @radius_in_miles int = 100; 

declare @radius_in_meters float = @radius_in_miles * 1081.7316;

declare @isWithinCircle int;

select @target.STBuffer(@radius_in_meters).STContains(@source) AS [isWithinCircle],
 @target.STDistance(@source) AS [distance_in_meters],
 @target.STBuffer(@radius_in_meters).STDisjoint(@source) AS [isPastCircle]
 into #MyTempTable;

 select @isWithinCircle = isWithinCircle from #MyTempTable

 select @isWithinCircle
