SQL Server Geography Functions Intersect

[AlbertoLópez]

Hi;

I have 2 layers (tables) in SQL Server/ArcGIS Enterprise Geodatabase and I have to intersect those layers and retrieve the areas of the intersections.

I am using a store procedure (SP) with geometrics functions in  SQL Server.

The layers in SQL Server are in Geographic Coordinate System GCS_ETRS_1989. But the results of the intersection and the areas returned by the SP  are not correct. The result I get doing the  intersect in  ArcMap does not give the same results.

The result in the SP is:

The result in ArcMap is:

I do not know if the problem is due to the Coordinate System. 

This is the code. Any ideas?. Thanks.

The first thing that comes to mind when talking enterprise geodatabases and different results between SQL outside of ArcGIS clients and results from within ArcGIS clients are versioned data.  If the data is versioned, make sure you are running your SQL outside of ArcGIS on the same versioned data as what is being used within ArcGIS.
