Hi all,
I am using SQL Server BI development studio to create a model. I get the error message when I run the report model wizard:
"Arithmetic overflow error converting expression to data type smalldatetime."
Please help.
Best regards,
I'm trying to create a few report models in Visual Studio to demonstrate the Report Builder tool and I'm encountering an issue when I try to generate a Report Model.
I get the error message "Specified Method Is Not Supported" when I click Finish on the Report Model wizard. The error detail is:
===================================
Specified method is not supported. (Microsoft Visual Studio)
------------------------------
Program Location:
at Microsoft.ReportingServices.ModelDesigner.Wizards.ChooseSemanticModelName.CreateSqlDsvStatisticsProvider(IDbConnection connection)
at Microsoft.ReportingServices.ModelDesigner.Wizards.ChooseSemanticModelName.BuildModel()
Steps to reproduce:
1. Create a new Report Model project in Visual Studio 2005 against SQL Server 2005
2. Create a new data source. The data source was tested and works correctly
3. Create a new data source view. The data source view was also tested (clicked on Explore Data) and I was able to look at the data in the view
4. Right-click on Report Models and select "Add New Report Model"
5. Click next at the welcome screen
6. Select the data source view created in #3
7. Leave the selected options for report model generation rules for creating the data source view
(Create Entities for all Tables, Create Count Aggregates, Create Attributes, Create Attributes for auto-increment columns, Create date variations, Create numeric aggregates, Create date aggregates, Create roles were all selected)
8. Click next
9. Select Update Model Statistics Before Generating (default option)
10. Click next
11. Click Run
Once I click run it processes for approx 3 seconds and then returns the error above.
If anyone could help me I'd appreciate it. Microsoft hasn't published any details on the namespace and I'm not sure why I'd be getting the error I am.
Thanks in advane,
Maurice
I try to create relational database but i cant develop a model. after i create a database i will create an OLAP cube for my project.i dont want to complex model but i cant create a simple database. it may be marketing, CRM or another. i dont know what fields and tables i should create. i saw sample databases such as northwind and foodmart but i must create original database for my project. please help meeeeee

Hello,
What we'd like to do is programmatically generate and maintain a report model based on how the individual install is configured. I've found some documentation that makes me believe this is possible, but I'm hoping someone can nudge me in the right direction. The ReportingServices2005 class has several model related methods (CreateModel) and I found the .xsd for the semantic model XML file
(http://schemas.microsoft.com/sqlserver/2004/10/semanticmodeling/SemanticModeling.xsd),
but no real documentation on how to put together a Report Model document from scratch. Looking at the files generated from BIDS is somewhat overwhelming and I have no idea where I'd pull most of the information.
Finally, I want to create Report Model(.smdl) file without Report Model Designer.
I want to Implement CreateModel Method to create new model, any source code sample..??
Any help that can be provided would be greatly appreciated. Thanks!

Hello!
I've created a data source that uses the OLE DB Provider for Teradata to connect to an existing Teradata database. Works fine.
I then use this data source within my project to create a Data Source View. Again, all works well.
However, the final step - creating a Report Model, bombs out in the wizard at the Completing the Wizard step with the following error: "[NCR][Teradata Database] Syntax error, expected something like a name between the 'SET' keyword and the 'TRANSACTION' keyword." (I elected for the wizard to only create entities for all tables, and create attributes).
If I try to create a Model manually, I get the following error when trying to build: "The Entity '<EntityName>' does not have any IdentifyingAttributes. Entity must have at least one IdentifyingAttribute."
Still fairly new to SSRS, so I'm hoping the issue is just a loose nut behind the keyboard Does anyone know what I'm doing wrong in trying to set this up?
Thanks in advance!
Hi,
I've tried those two operations in the Management Studio.
Though we can create a mining structure and mining model in Management Studion,
but we cannot process the analysis-service database.
(1) I create only a mining structure through CREATE MINING STRUCTURE.
No error reported. But if I process the analysis-service database in Management Studio I always get error
'Error : The '<mining_structure__name>' structure does not contain bindings to data
(or contain bindings that are not valid) and cannot be processed.
I then tried to create it by creating and running an XMLA script. It was successful.
However, it's much harder to learn XMLA.
If any of you created an analysis-service database in Mgt Studio, and create a mining
structure in the same place using DMX script, can you process the database?
(2) Is there any use of CREATE MINING STRUCTURE operation without binding
to any table? Examples I saw so far did not show relating it to do. In my experience
processing the analysis-service database with that mining structure is doomed to fail.
(3) Is there any way we can create mining structure through CREATE MINING
STRUCTURE operation in Management Studio and use RELATED TO clause
to bind it to any Relationship to an attribute column (mandatory only if it applies), indicated by
the RELATED TO clause
(4) If this is the fact, is there any use of CREATE MINING STRUCTURE operation?
If we use BI Dev Studio, it's much easier to use the wizard.
(5) I found I cannot create a mining model inside a mining structure through operation
CREATE MINING MODEL. If you call that operation, you end up having a mining
model and a mining structure with the same name. I found that in order to create a
mining model inside a mining structure you have to call operation ALTER MINING
STRUCTURE ADD MINING MODEL. Is it true this is the only way?
Thank you,

I use data model as the datasource of my report. I want to create a new field basing on a date type field.
So I create a new field with function like this 'DATEADD(MONTH, 3, #8/18/2009#)', but there is always a error message box said 'the arguments to the following function are not validATEADD'
How should I write this function?
I get the following error when I try to load the mining model in the mining model viewer
Query (1, 6) The '[System].[Microsoft].[AnalysisServices].[System].[DataMining].[NeuralNet].[GetAttributeValues]' function does not exist.
I get a similar error when I try to load the Load Mining Accuracy Chart
Failed to execute the query due to the following error:

I have made a clean install of SQL 2014 including MDS on a server with Win Server 2012 R2.
After the installation I cant create new models because on an error saying that "Must declare the scalar variable "@Version_Id". "
I can see that the tables gets created in the MDS database but the models dont show up in the web interface.
I get the same error message when I try to deploy an old model.

I have a small VB.Net 2005 app using the Microsoft.SQLServer.ManagedDTS.dll so I can use the SSIS/DTSx functionality.
The program ran fine in the IDE.
Then when I tried to create a setup project for it I recieved a warning that all dependancies for MSXML6.DLL were not found.
I clicked ok and the setup was created.
I tried to run the setup and it failed with "....msxml6.dll failed to register. HRESULT -2147023782. ...
So I said cancel the setup and registered msxml6.dll.
I deleted my setup project and recreated it. This time I did not get the warning about msxml6.dll dependancies.
I tried the setup again and it executed without any errors however when I run the program I now get:
"Cannot create an instance of the XML Document Object Model. MSXML may not be registered."
So I went back into the IDE with the project and now it will not run either. IT gets the same error.
Does anyone have any suggestions?
Hi,
I have found that in the autogenerated model attributes are missing for those fields that have relations to other tables. At first, it may look reasonable since a user can still get down to the field's value through the relation/related table. However, if the relation's key fields is the only thing the user wants to display, then going down to the related table is an overkill.
I can add an attribute manually and bind it to the key field(s). Is there an option in the autogeneration process to do it automatically? The only post I've found so far suggests to do everything manually (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1152575&SiteID=1). Is this the only way?
Thank you,

I created a data model for report builder. And since it wont let me use views, i tried to put all the tables im using in one of my already made views, to create a data source view like my sql view. But when i connect everything the same, my report model still doesnt narrow my search. I only want to see Breed information, but since i have a Breeder table,and Customer table, its showing me all customers, and not limiting it to the ones that are breeder customers.
heres the tables:
Code Snippet
FROM dbo.Tbl_Customer INNER JOIN
dbo.Tbl_Customer_Breeder ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_Breeder.Customer_Code INNER JOIN
dbo.Tbl_Customer_Detail ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_Detail.Customer_Code INNER JOIN
dbo.Tbl_Customer_Category ON dbo.Tbl_Customer.Customer_Category_Id = dbo.Tbl_Customer_Category.Customer_Category_Id INNER JOIN
dbo.Tbl_Customer_Classification ON
dbo.Tbl_Customer.Customer_Classification_Id = dbo.Tbl_Customer_Classification.Customer_Classification_Id INNER JOIN
dbo.Tbl_Customer_In_Breed ON dbo.Tbl_Customer.Customer_Code = dbo.Tbl_Customer_In_Breed.Customer_Code INNER JOIN
dbo.Tbl_Breed ON dbo.Tbl_Customer_In_Breed.Breed_Id = dbo.Tbl_Breed.Breed_Id
What am i doing wrong, and are there any suggestions.
Hi,
Te following situtation is :
ReportModel is created ,there is only a named query in DSV ,it has a few tables in it(The relationship are inner joins and outer joins).
The question is how could I create a unique logical primary key to identify each unique row in the named query dataset, and also you cannt generate a model unless the named query has a logical primary key . how can I solve this problem,any help?
I've been through a number of tutorials on how to enable row-level security based on a userID, but my problem is more complicated and I do not have sufficient understanding of report models to guess.
My security information is defined in a table within my database. It contains a username and an account mask. An account mask maps to 1 or more account codes contained in the other data tables in my report model. A user may have more than one account mask defined for his account.
I understand the concept of directly mapping the logged-in user to a field containing a matching username. Is it possible to do a two-step mapping, so that based on the user ID I can get the account mask(s) and then evaluate which account codes match the mask(s)?
Or is there a different/better way to set this up? Defining SQL roles/groups is not an option, because of some compatibility issues with external systems.
So far, because my security table has no defined relationship with the data tables, I have not even been able to get it into my report model (Would love any suggestions on that one, too.)
I'd appreciate any ideas or suggestions - even if only something to investigate.
Thanks,
Sarah
I have a stored procedure that takes a date range and returns all the sales in that date range. I'm trying to create the report model for ad-hoc reporting. When I go to create the dataset view, it only lets me select tables or views.... how do I get around this?
View 2 Replies View RelatedI am attempting to create the "Classification - Children at Home" Data Mining Model as described in Larson's book.
Each time that I create it.. ONLY the ALL LEVEL is shown and it is impossible to expand the model to look at the Decision Tree, Neural Network, or the Clustering model etc. Drill down is enabled (tried it with and without enabling the drill down).

Hi,
I am trying to model data in analysis services with the Advance Create Mining Model function in the excel addin. I am having trouble creating an association model that works like the Associate button above the Advanced button.
The format of my data is like this
OrderID Product
100 Bike
100 Helmet
100 Shoes
200 Helmet
200 basketball
200 Bat
300 Shoes
300 Socks
The associate button works perfectly since it asks me which column is the transaction id (orderid) and which column I am trying to predict (product). The advanced create mining model asks me to determine what the columns are...
OrderID=key Product=Input+Predict?
When I run the advance create mining model associate, I get a browser that gives me no rules and the support for only one item itemset (each product but no combination of products).
Does anyone know what I have to do to get it to work like the associate button?
New to Reporting Services. Installation seemed to go well. All green checks on the Reporting Services Configuration page.
In Reporting Services when I click New Datasource... My connection type is Microsoft SQL Server. This is my connect string... data source=PeninsulaPoint;initial catalog=UHSSelfService. I have checked the Windows integrated security radio button. Then I save the Datasource. I then edit the datasource to Generate the Model to be used in Report Builder. When I click Generate Model, give the Model a name and click ok I get the following error.
Cannot create a connection to data source ''. (rsErrorOpeningConnection)

Hi, everyone here.
I am trying to get the training error of the model processed which can reveal how much the model fits the cases. The training error can reveal how many cases (from training set) are classified correctly. The lower traing error is, the more the model fits the training set. (Maybe overfitted) But I found it hard to get. I saw the life chart in AS 2005 which I am not quite understand and don't know how to code it in my program.
Is there some way to getting traing error or predicting error?
I am now using this awful way to get the training error:
select t.*,CollegeTree.CollegePlans as pred
from collegetree
prediction join
openquery(DSource,'select * from CollegePlans') as t
on CollegeTree.StudentID = t.StudentID and
...
where t.CollegePlans = CollegeTree.CollegePlans;
and then use datareader.ItemCount to get the count of cases which classified correctly.
Keyword: train error,predict error, data mining, analysis service
The model specified must be a generated model. (rsModelNotGenerated)
This error comes up after clicking on the new report model. The report model and datasource deployed to the sharepoint server with no issues.
I've searched forums and found responses from 2006 forward, but none that I'd find satisfactory, so if anyone can help, I'd appreciate it.
I'm using SQL have SQL Server Reporting Services 2005 SP2. I've successfully used SQL Server Business Intelligence Development Studio to create reports and charts from data stored in an Oracle 10g database.
I have a distributed team and while I'm creating the official reports, I need them to be able to utilize the Report Builder to create their own reports for day to day management of their own activities.
I created a Data Source and a Data Source View successfully. When I tried to utilize the Report Model Wizard to create a report model the builder can use, I get an error.
ORA-02179: valid options: ISOLATION LEVEL { SERIALIZABLE | READ COMMITTED }
I've read that this was ''fixed" with SP2. I've also read that there are work-arounds (which I don't necessarily understand). However, I've read plenty of MS documentation that says that this should work.
Can anyone provide any clarity around where my problem lies and how I might mitigate?
