Map the hierarchical queries pseudo column level

Question

Is it possible to map the hierarchical queries pseudo column level in the Workbench?
I have an object for which I use connect by queries. I would like to map the pseudo column level. is this possible? if yes, how
If the mapping is not possible how do I get the level using a report query?
Is there any other way to retrive level?
Thanks

Answer 1

Thanks James, appreciate your feedback.
I tried report.addItem("level", builder.getFunction("LEVEL"));
but the query TopLink generates has LEVEL() and it errors out.
Code -
Expression startExpr = null;
Expression connectBy = builder.get("manager");
Vector<Expression> order = new Vector<Expression>();
order.addElement(builder.get("name"));
report.setHierarchicalQueryClause(startExpr, connectBy, order);
report.addAttribute("name");
report.addItem("level", builder.getFunction("LEVEL"));
Query generated by TOpLink - SELECT NAME, ID, LEVEL() FROM EMPLOYEE WHERE (EMPLOYEE_TYPE = ?) CONNECT BY PRIOR EMPLOYEE.MANAGER_ID = EMPLOYEE.ID ORDER SIBLINGS BY NAME
bind => [M]
