Hi,
I am a newbie to this OLAP area.
I have this table (company_dimension) where every company has a parent,
which in turn can be a child to another parent and so on. It is about 10
levels deep.
TEST@D0MARS> desc company_dimension
Name Null? Type
----------------------------- -------- --------------------------------
COMPANY_CODE NOT NULL VARCHAR2(50) ---> primary key
COMPANY_DESC VARCHAR2(100)
PARENT_COMPANY_CODE VARCHAR2(50) ---> foreign key
pointing to company_code
The following table maintains the mobile phone numbers for every company.
TEST@D0MARS> desc DLY_TRANSACTION_DETAIL
Name Null? Type
------------------------------ ------ --------------------------------
ACTIVITY_DATE DATE
COMPANY_CODE VARCHAR2(10) ---> foreign key to the
company_dimension table
MOBILE_NUMBER NUMBER(10)
The requirement is to get all the phone numbers for a given company and its
children for a given day. Since I cannot join these 2 tables using the
'connect by' clause, how can I accomplish it, without using a sub-query?
(actually 2 other dimensions play a role in the above table and I have
simplified the structure)
Created a dimension on the company_dimension table and used the
dbms_olap.validate_dimension procedure to validate it. Everything looks
good, but none of the manuals explains how to use the dimension in a query.
This is Oracle 8.1.7 on Sun Solaris.
Thanks in advance.
