Offers a fast, index-only intersection method to determine if a geography instance intersects another SqlGeography instance, assuming an index is available.
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)] public SqlBoolean Filter( SqlGeography other )
- Type: Microsoft.SqlServer.Types.SqlGeography
Is another geography instance to compare against the instance on which is invoked.
Return ValueType: System.Data.SqlTypes.SqlBoolean
A SqlBoolean value that specifies whether the specified SqlGeography instance intersects the current SqlGeography.Returns 1 if a geography instance potentially intersects another SqlGeography instance. This method may produce a false-positive return, and the exact result may be plan-dependent. Returns an accurate 0 value (true negative return) if there is no intersection of SqlGeography instances found.
In cases where an index is not available, or is not used, the method will return the same values as STIntersects when called with the same parameters.
This method is not deterministic and is not precise.
