Hi
Is there a automatic way to get all the points of an ellipse stroke, without the filling points.

On the other hand you may want to map some spatial data that span all over the map.

Is it possible to query just the first object in a SDO-geometry data type? for example of if i have the following
(2001, 8307, (-117.47196, 33.758424, ), , )
How do i query that 2001? Thanks

Answer Snippets (Read the full thread at oracle):
Similarly to get the SRID, you can use select t.<geometry.
Hi user8602786,
select t.<geometry column>.sdo_gtype from <table name> t
The trick is to make sure you use a table alias.
