Geometry 實例代表 Euclidean (平面) 座標系統中的數據。 瞭解如何在 SQL 資料庫 Engine 空間數據中建立、建構及查詢幾何數據。
selectid,geo.ToString()ASgeofromT_Geometry; 2. 查询转换面积 使用STArea(),返回类型:float -- 查询转换面积,非多边形查询结果为0selectgeo.STArea()fromT_Geometry; 3. 结束 相信应该很清楚的明白了SQL Server geometry类型的插入和查询的方法了吧。
平面空间数据类型geometry是作为 SQL Server 中的公共语言进行时 (CLR) 数据类型实现的。此类型表示欧几里得(平面)坐标系中的数据。 注册geometry 类型 geometry类型已进行预定义,并可在每个数据库中使用。您可以创建geometry类型的表列并对geometry数据进行操作,就像使用其他 CLR 类型一样。
