问题描述

我正在尝试运行查询(我从

I am trying to run a query (which I gleened from here) against GeoJson multipolygon data. It processes many of the spatial records but is stopping on a some.

查询消息中出现以下错误:

I get the following error in the query messages:

该查询将运行并产生一些结果,但是当它查询到NAME ='Fairfax'和'Roanoke'的记录时,它将因上述错误而停止.

The query will run and produce some results but when it hits records where the NAME = 'Fairfax' and 'Roanoke', it stops with the above error.

任何人都可以看到该问题并知道如何解决吗?

Can anyone see the issue and know how to resolve this?

推荐答案

感谢@Hank对该查询进行了优化! @ Vitaly-Borisov强调了特定的违规几何形状,这在解决问题上有很大帮助.

Thanks @Hank for taking this query for a spin! @Vitaly-Borisov has highlighted the specific offending geometry, this has helped immensely in solving the issue.

在原始查询中,有一个CROSS APPLY查询创建了一个名为PolygonData的结果集,紧随其后的是一个OUTER APLY创建了一个称为MultigonData的结果集.

In the original Query, there is a CROSS APPLY query that creates a result set called PolygonData, immediately after that is an OUTER APLY that creates a result set called MultigonData.

请注意,MultigonData仅具有结果WHERE LEN(Path) = 0
这里的期望是所有非多边形几何都将为Path生成一个空值,因此,如果几何确实是MultiPolygon类型,则我们仅尝试解析MultiPolygon WKT.

Notice that MultigonData only has results WHERE LEN(Path) = 0
The expectation here was that all non polygon geometry would yield a null value for Path and so we only attempt to resolve the MultiPolygon WKT if the geometry was indeed a MultiPolygon type.

此查询仅支持Polygon和MultiPolygon类型的几何,这是当时适用的足够广泛的假设.

This query only supports Polygon and MultiPolygon types of geometry, it was a broad enough assumption that suited at that time.

我们可以使用类型定义本身来代替使用故障解析多边形(WHERE LEN(Path) = 0)来确定几何图形实际上是MultiPolygon.

Instead of using the failure to resolve a Polygon (WHERE LEN(Path) = 0) to determine that the geometry is in fact a MultiPolygon, we can use the type definition itself!

更新的查询,请注意PolygonDataMutigonData查询中的where子句以及shapeDef
COALESCE的使用 这些细微的变化将使其他地理类型更容易采用这种逻辑.

Updated Query, notice the where clauses within the PolygonData and MutigonData queries and the use of COALESCE in shapeDef
These minor changes should make it easier to adopt this logic for other geography types.

更新:要素集合标头已被修改以匹配OP.
SRID现在来自要素集合标头,并且没有经过硬编码

UPDATE: The feature collection header has been modified to match OP.
SRID now comes from the feature collection header and is not hard coded
