Hierarchical Tree

I have the following tables (simplified for effect).

 

CREATE TABLE "CALCULATION"

   (    "ID" NUMBER(10,0),

        "ROOT_ELEMENT_ID" NUMBER(10,0)

   ) ;

 

CREATE TABLE "CALCULATION_ELEMENT"

   (    "ID" NUMBER(10,0),

        "NAME" VARCHAR2(255 CHAR ),

        "PARENT_ID" NUMBER(10,0)

   ) ;

 

ALTER TABLE "CALCULATION" ADD CONSTRAINT "FK_CALC_CALC_ELEM" FOREIGN KEY ("ROOT_ELEMENT_ID")

          REFERENCES "CALCULATION_ELEMENT" ("ID") ON DELETE CASCADE ENABLE;

 

ALTER TABLE "CALCULATION_ELEMENT" ADD CONSTRAINT "FK_CALC_ELEM_PARENT" FOREIGN KEY ("PARENT_ID")

          REFERENCES "CALCULATION_ELEMENT" ("ID") ON DELETE CASCADE ENABLE;

 

 

What I would like to do is create a query/view that allows me to select all calculation_elements for a particular calculation id. Ie the calculation points me to the top of the tree of calculation_elements. The results should look something like this:
