Processing Association Rules model on SQL 2005 Standard edition produced following error:
"Error (Data mining): The 'WO_3' mining model has 6690 attributes. This number of attributes exceeds the attribute limit of 5000 allowed by the current version of the algorithm associated with the mining model."
How can I limit number of attributes in a model?
Thank you
Can i have a combination of sources some with Unique Identifiers and some without?
I need to know what happens when I have option “Create Code values automatically” selected for the entity and same time pulling Unique Identifier for other sources in same entity stage table.
When we select option “Create Code values automatically” for the entity we creates, then during load from external source to MDM stage we don’t send any values to MDM stage “Code” field and in next step when we execute the stored procedure to load the data from MDM stage to MDM model, it assigns the Code values to each record in MDM stage and MDM model.
I need to know whether after executing the store procedure, will it assign Code values for only NULL records in MDM stage and not give us any error for the records that already have Code values present in MDM stage.
This is a general question about data modeling. I'm more curious than anything else.
There is much talk about over-training data model, and I'm sure there are under training as well. As a rule of thumb, depending on the algorithm, what is a good ratio of attributes vs data points?

I am working in SQL Server Master Data Services Version 11.0.5058.0 (SP 2).
I have been asked to group all the financial attributes together. When I move one of the attributes up using the arrows, it works good jumping over one attribute at a time. Then I reach a section of attributes where it leap frogs over 24 attributes.
It appears these 24 attributes are in a subgroup but there are no attribute groups and I removed the subscription view from the entity. If I move one of the 24 attributes in the group, it moves it outside of the 24 attributes.
This is under leaf member attributes. There are no collection or consolidated groups.
I'm using a DW from Northwind database to build a cube to do some analitical taks. I already create the cube and now I am "cleaning" the dimensions. I'm having some difficults to understand the logical off this part. The reason is that When I create the Data Source View, I only import the Foreign Keys that connect the Dimensions to Fact_Table. I have to drag the attributes of Dimension from Data Source View to the tab attributes?
Imagine this:
I have the following dimension:
Dim_Customer:
Customer_ID
Name_Customer
Job_Function
Date_of_Birth
Contact
Address
City
Country
When I create the cube only Customer_ID appears in attributes tab, it's normal?
One more question:
I don't want to create a hierarchy like:
Customer ID -> Name_Customer
Customer ID -> Date_of_Birth
Customer ID -> Address
Customer ID -> City
Customer ID -> Country
My idea is to create the following hierarchy:
Name_Customer -> Date_of_Birth -> Address -> City -> Country
But the first hierarchy that I show is always appears to me. Do you know what is happens?

Hi,

HI all !
I am having a bit of a problem trying to limit a number of columns in a matrix appearing on a page.
At the moment, I have a dataset that lists the month and the mail packages that were sent during the month
The matrix works great HOWEVER, if there were more than 8 months in the matrix columns, it does not break and would make the page look like a huge landscape page.
I am trying to limit the number of columns appearing (this is the months column) on the matrix so that the pages stay in a potrait position. IE: every 8 columns appear on one page. Is there an option or an expression I could use in the Matrix ?
Thanks!

Is there a limit of how many rows a table can have in SQL compact Edition? I didn't find anything in the documentation, but I get regularly a funny error message "Expression evaluation caused an overflow. [ Name of function (if known) = ]" when I try to create record number 32768 (is equal to 2 to the power of 15).
Where is this limit documented ?

Hi There,
I would like to know what the recommended Number of Sql Mobile Databases Per Application?
I appreciate any response!
Thanks!
In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.

Hello all-
I have a specification table that has some attributes defined.
SpecId - Id of the specification
Attribute - Attribute of the spec. (Like Color, HP etc)
Value - Is the value of the attribute
Then I have a car table that actually has information about the cars. Intention is to take each specification and match the cars that match the specification. If the car has more attributes than the spec, we ignore the extra attributes for the match. But if the car has less attributes, we don't even consider the car as a match (even if the attributes present, match). To summarize, the car's attributes should be >= spec's attributes.
The code I have below is bad because I am joining the same tables twice. In addition, it fails in the condition "the car's attributes should be >= spec's attributes"
Any help is greatly appreciated.
DECLARE @Specification TABLE

Is there a performance limit on the number of indexes per table / database ? With Filtered indexes there appear to be many more opportunities for more finely defined, and therefore smaller indexes resulting in many more indexes on a single table.

Our development team wanted to create a database user for each application user in the application and use these for granular data access control, which at first, sounded like a good idea but our initial testing ran into some interesting results.
Our target user base was about 15 million users with an estimated 1% concurrency rate, and finding no MS documentation on an upper limit to the number of users a database can have we began some load testing to see how the database performed. In the hundreds of thousands of users range our test database had a hard time performing well under light loads (even without any concurrent connections).
When we purged the users and reverted back to just a handful of service accounts, performance went back to "normal" under the same loads. I began to wonder if this is a situation where throwing more hardware at the problem would overcome the issue or if there is a practical upper limit to the number of users a single database can handle well.
(There were of course other cons to this arrangement and I certainly was never going to expand the users tree in the object explorer for a database like this, but we thought it a solution worth investigating.)
What is the largest number of users any of you have had in a single database?
Hello everyone,
I'm having an issue with dynamically setting the Send Mail task's to field to decent sized recipient list(approx 15 email addys). The strange thing is that this same package works fine if I'm using a list of say 4 email addys. I have double checked everything I can think of....list is seperated by semicolons, each address looks good....and have ran script tasks to check my variables along the path of the package but so far have not found the reason. The error I get is below:
"The specified string is not in the form required for an e-mail address"
Also of note, these addresses are being populated from a table, that is then setting the To string of the send mail task via a seperate variable...that variable being populated from a foreach loop. Again, all of this works fine with a smaller recipient list. Any ideas?
The only thing I can think of right now is to run the send mail task within the foreach loop...but then I'll be sending a seperate email for each address and would like to avoid that if possible.
Thanks,
Adrian
