使用ST_SPHERICALDISTANCE的两个地理坐标之间的Teradata距离

Question

我已经阅读过Teradata版本13中的内容，您可以使用ST_SPHERICALDISTANCE来计算地理距离。 我在Teradata中写了一个简单的测试查询：

Select
Cast('POINT(-35.0000, 150.0000)' As ST_GEOMETRY) As location1,
Cast('POINT(-35.0000, 149.0000)' As ST_GEOMETRY) As location2,
location1.ST_SPHERICALDISTANCE(location2) As Distance_In_km

但收到以下错误：

  

未交付Teradata行（trget）：13   OGRGeometryFactoryX :: createFromWkt失败。

这是查询或配置的问题吗？ 感谢

Answer 1

只需删除点定义中的逗号：）

Select
Cast('POINT(-35.0000 150.0000)' As ST_GEOMETRY) As location1,
Cast('POINT(-35.0000 149.0000)' As ST_GEOMETRY) As location2,
location1.ST_SPHERICALDISTANCE(location2) As Distance_In_km

顺便说一句，另一种创造点的方法：

NEW ST_GEOMETRY('POINT(-35.0000 150.0000)')
