Hi there,
I am trying to make an OLAP cube on a table having two columns (datetime,
Number_of_times _an_event_occur ed).
My dimension is time and I want to measure the Min and Max times an event
occured over time.
I have no problem in calculating Maximum occurance of events over time.
However, I have some NULL values in my Number_of_times _an_event_occur ed
column, due to which I don't see any result when I try to calculate
Minimums.
If I do a "select MIN(Number_of_t imes_an_event_o ccured) from Table1", I see
correct results. I read that Analysis Service treats NULL as 0 if there is
any other numeric (non-NULL) field present. However, for calculating my
Minimum Value, I need to ignore these NULL values and have my Min-Max
calculation on the rest of the data.
Could someone explain me this anamoly and how I can see the correct Minimum?
TIA.

Hello,
If I wrote the next ebay (yes I know, yawn-snore) and I had a database
with 5 million auction items in it, what would be a really good
strategy to get a search done very quickly? Would it involve
something called OLAP and/or "data mining"? The only technology I am
familiar with is simply SQL Server databases with stored procedures.
I think I'd be guessing correctly and say that this technology simply
wouldn't be fast enough *on...

I use C# to invoke DTS. The DTS run successfully if no
process cube function in it. But after i add process cube
function, the ASP.NET page hang.
I even impersonate ASP.NET to an account with OLAP
Administrator and System administrator. it jus hang
there. So what is the problem I'm having? It is working fine when no
processing OLAP command in it.

After a brief search, I didn't find any python package related to OLAP
and pivot tables. Did I miss anything ? To be more precise, I'm not so
interested in a full-blown OLAP server with an RDBMS backend, but
rather a pythonic API for constructing datacubes in memory, slicing and
dicing them, drilling down or up dimensions and exposing them in some
suitable form to a presentation layer. I've hacked a first cut of a
pivot table...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
