Use of Complex Folder in Discoverer Administrator

Question

Hi!
Can anybody help me? I’ starting to use the Discoverer
I've this view
CREATE OR REPLACE VIEW CATEGORY _V
(ID, TLI_ID, TQU_ID, CODIGO, DESCRICAO)
AS
SELECT cat.ID, tli_id, tqu_id, tlic.codigo, tlic.CLASS
FROM CATEGORY cat, TYPE_LICENCE tlic
WHERE tli_id IS NOT NULL AND tqu_id IS NULL AND tlic.ID = cat.tli_id
UNION
SELECT cat.ID, tli_id, tqu_id, tql.codigo,tql.CLASS
FROM CATEGORY cat, TYPE_QUALIFICATION tql
WHERE tqu_id IS NOT NULL AND tli_id IS NULL AND tql.ID = cat.tqu_id
This view gets together the class from two different tables,
When one has a class another has null (vive-versa) and I need them both as this view does.
I’ll need this class for get grades for the students of this school and things like this.
I suppose, I've to do a complex folder and joins from:
3 Joins:
Id.CATEGORY = Id.CATEGORY_V
Id.TYPE_LICENCE = tli_id.CATEGORY _V
Id.TYPE_QUALIFICATION = tqu_id.TYPE_QUALIFICATION
After I've to do a complex folder? And drag what to this complex folder, I don't know:
id of TIPOS_LICENCA
CLASS of CATEGORY_V
id of TYPE_QUALIFICATION (error doesn’t let me :S )
Thanks

Hi
In complex forlder you can't create select with union by drag and drop.
Create an SQL folder with the select of the view.
