Error when using Spatial Index in SQL Server

问题:

I use Spatial Index and when I try to execute WHERE statement:

WHERE T.GEOMETRY.STIntersects(O.GEOMETRY) = 1 AND T.GEOMETRY.STTouches(O.GEOMETRY) = 0

It works fine, but when I try to execute with OR:

WHERE T.GEOMETRY.STOverlaps(O.GEOMETRY) = 1 OR T.GEOMETRY.STWithin(O.GEOMETRY) = 1

I get this error:

The query processor could not produce a query plan for a query with a spatial index hint. Reason: Could not find required binary spatial method in a condition. Try removing the index hints or removing SET FORCEPLAN.

Any help, what is a problem in this statement?

回答1:

A general solution for issues with OR queries ( typically performance) is to separate them and use UNION ALL between then. This would typically be done in a sub-query, or a Common table expression.

If you could post more of your query, and preferably the relevant table schema, then I can update my answer with a more detailed answer.
