connect Oracle Spatial, read Geometry an reproject

Starting from the Oracle Connector Node, the DB Query Reader follows with an SQL statement, such as:
SELECT
SD_UTIL.TO_WKTGEOMETRY ("columnname with the geometry data") AS geometry_column_wkt
FROM
"TABLENAME"
Then a WKT to Geometry Node follows to project the WKT back into its original geometry.
In this case project into another geometry an calculate area.
