calendar_date calendar_month calendar_qtr calendar_year
20020101 1 1 2002
20030101 1 1 2003
Mhhhhh...
The calendar_date(or changed to calendar_day) should be just the day of the
month since you already have calendar_year. It seems that you are storing
everyday's day.
Or get rid of calendar_year and calendar_month since calendar_date contains
month, and year?

Ok i'm messing with dimensions.
dm_time to be exact:
create table dm_time
( calendar_date date not null,
calendar_month number(2) not null,
calendar_qtr number(1) not null,
calendar_year number(4) not null);
insert into dm_time values(to_date('20020101','YYYYMMDD'), 1,1,2002);
insert into dm_time values(to_date('20030101','YYYYMMDD'), 1,1,2003);
2 rows nice and simple
trying to validate the dimension comes up with an error, my guess is
because of the design of the table
where basically calendar_date is child of
calendar_month is child of calendar_qtr is child of calendar_year,
wont validate.
- the question i have is this, should month really be like 2002-01 with
the year included, likewise with qtr, then it
will validate ok.
Was the design of dm_time just dont wrong or am i missing something here.
thanks, joe
