Cannot Create private Time Dimension

I have a fact table with 32.000.000 rows. In cube editor , I want to create
a
private time dimension based on a datetime type column of my fact table.
after I press next button on "select advanced options" window, several
minutes passes and then a "finish" button appears in the same window
instead of next button. when I pressed finish, I got pop up message "the nam
e
cannot be an empty string" but I have no place to write the name of the
dimension.I typically discourage creating a time dimension like this. I strongly
recommend that you create an independent dimension table which incorporates
"Time". Then use the timestamps from your fact table as FKs to this
dimension. This is normally the best approach because it:
1) allows you to model data which does not exist, e.g. holidays, weekends,
etc, which are not represented in your fact table.
2) dimension processing goes much faster (i.e. you don't have to scan
multiple rows); this is particularly true here because the system will issue
a SELECT DISTINCT to process the private time dimension.
3) private dimensions must always be reprocessed when you process the fact
table -- which can greatly increase your overhead (see #2 above)
4) you will always be limited to a single partition because you can't build
across multiple fact tables (which can limit your scalability, query
response time, rolling "n" months -- all of which use multiple partitions).
5) if you create an independent time dimension table, you can have
interesting extensions to just a timestamp, e.g. model holidays, seasons,
work-days compared to weekends, etc.

sql

cannot create connection

I created a report using Report Designer. The Dataset is working fine. In
fact, the Data tab shows me the expected query result. But...
when going to the Preview tab, I get "Cannot create a connection to data
source <name> . Login failed for user 'sa'.
Further info:
1) if I go to Tools / Connect to database and enter the info in "Datalink
properties" (server name / specific user name passw / database name) and hit
Test connection, I get "Connection succeeded"
2) During creation of data source for a SQL Server machine on the network
when connecting with winNT security I get an error while trying to access the
database list.
What am I doing wrong ' THnksHi,
Go to your "Shared Data Sources" click on the datasource you use for your
reports, open the properties by double clicking on the "credientials" tab
enter your password again and save it.
It should work.

Cannot Connect to SQLExpress

Hi everyone,

I'd like to ask some help. My prob may seem very basic but as a matter of fact i'm a newbie to .net and sql 2005. I'm trying out this product but I encountered an error. After installing sql server express 2005, and using my server instance name (the default name "SQlExpress" during install) and password to connect, I always get the error "Timeout expired. The timeout period elapsed prior to completion... blah blah blah". Though I entered the right user name and password (which I entered during install), I always get this error.

Additional: I indicated mixed mode during install and defined my sa account and password

Anyone who can help me.. like adjusting configs, etc...
Kobe

Is the SQL Server service started?

Also, refer to the blog posted here:

|||Thanks Rob! This helped me a lot.|||Chaps,

I have the same problem. (Including the novice attributes).

What was the fix? I looked through the blog as suggested but could not readily find the cure.
