Added a simple ST_AsShape UDF returning the Esri shape representation. #102

There was a need for that. The Esri shape representation can be used for exporting the geometries into other data stores like HBase.

Thanks! We will take a look.

It would be nice to also have the complementary ST_GeometryFromShape, but that could be separate.

randallwhitman commented 7 years ago

Code review looks OK. I cloned, and it built OK and unit test passed. In hive I ran create table randall.t002 as select st_asshape(st_point(1,2)) shape but I'm not sure what to do with that table not having ST-GeometryFromShape.

randallwhitman commented 7 years ago

I was able to verify the shape buffer written to my randall.t002 is point(1 2).

For clarification: we need this shape representation because we are using Hive to write into HBase and we developed a custom datasource using ArcObjects and the HBase Java API. This way we can easily query our big data using Hive and show those query results using the ArcGIS platform.

I will take a look at to ST_GeometryFromShape method this week.

Thank you.

Sounds great, thanks.
