如何为地理数据类型列添加值？答案

【问题标题】：How to add value to geography datatype column?如何为地理数据类型列添加值？

【问题描述】：

我正在尝试在t-sql 中插入一条记录，如下所示。我对向地理数据类型列添加值感到震惊。

这是一个地理值：

data = 0xE6100000010C8FE4F21FD26F49406002B7EEE6A9E13F

请告诉我如何在t-sql 语句中为地理值添加价值。

插入语句

    GO

INSERT INTO [dbo].[GeographicLocation]
           ([RecordGUID]
           ,[Postcode]
           ,[Eastings]
           ,[Northings]
           ,[Longitude]
           ,[Latitude]
           ,[MilesFromWisley]
           ,[MilesFromRosemoor]
           ,[MilesFromHarlowCarr]
           ,[MilesFromHydeHall]
           ,[NearestRHSGardenId]
           ,[Geolocation]
           ,[CreatedBy]
           ,[CreatedOn]
           ,[UpdatedBy]
           ,[UpdatedOn])
     VALUES
           (newId()
           ,'A1 3cc'
