Hi,
I've tried to use the export command to export a mining model from management studio, but it returns that
export statement is not supported for OLAP mining structures, Ive checked the EXPORT(DMX) reference I can't see any note that it is not applicable on OLAP structures.
Can anyone confirm this?

Dear friends,
I encounter a serious problem.
I would like to develop an application that can create Data Mining structures and a mining model in SQL Server 2005 with VB.NET. I tried the code from book Data Mining with SQL server 2005 in chapter 14 but did not work. Any good idea?
Please help me.
Best regards,
Manolis
Thank you very much for your help.
The errors that I can see in the code that you gave in your answer are the following and they are more or less the same as I had previously
I tried the code but initially I have encounter the following problems.
1. In any line that have the declaration As Server, As Database like in
Public Function CreateDatabase(ByVal srv As Server, ByVal databaseName As String) As Database gives me the problem that type Database is not declared the same type Server is not declared and it does not give me any option.
2. In addition to that for As DataSource, As RelationalDataSource, As RelationalDataSourceView, As ScalarMiningStructureColumn, As DataSourceViewBinding, gives me the problem that type is not declared.
3. Finally in mc = New MiningModelColumn("Yearly income", Utils.GetSyntacticallyValidID("Yearly income", Type.GetType(MiningModelColumn))) is not accesible in this context because it is 'Private'.
I have some more problems but I thing that by solving the above that I referred I will solve the rest.
Thank you any way.

I perform data mining on all products and a specific product category.
Do I need to create 2 data source views, one for all products and the other one for the specific product category?
Afterward, I run the Data Mining Wizard 2 times to create 2 mining structures.
I also need to add the same mining model (e.g. Bayes, Cluster) to each of these mining structures.
Is there any simple way to do it?
Thanks.
Joe.
Hi ,all here,
Thank you very much for your kind attention.
I just found that I am not able to view the accuracy chart for my mining model. The error message is: no mining models are selected for comparision. Which is quite strange.
Any guidance? thank you very much.
With best regards,
Yours sincerely,
Hoping someone will have a solution for this error
Errors in the metadata manager. The data type of the '~CaseDetail ~MG-Fact Voic~6' measure must be the same as its source data type. This is because the aggregate function is not set to count or distinct count.
Is the problem due to the data type of the column used in the mining structure is Long, and the underlying field in the cube has a type of BigInt,or am I barking up the wrong tree?
I'm a beginner with SQL 2012 SSDT & SSMS. I get this error message when I try to deploy my project:
"Error 6
Error (Data mining): KEY SEQUENCE columns are not supported at the case level. The 'Customer Key' column of the 'TK448 Ch09 Cube Clustering' mining structure contains content that is not valid.
0 0
"
I am finding it hard to locate the content that is not valid. I've been trying to find a answer for this problem but can't seem to find anything. How can I locate the content that is not valid and change or delete it so that I can deploy this solution?
I am building a data warehousing solution without using analysis services or OLAP or OLTP....
Dont ask why ... but I have to....
Ok so which table structure would be better ?
dimention 1|dimention 2|dimention 3|matrix 1|matrix 2|matrix 3|matrix 4....
or
dimention 1|dimention 2|dimention 3|matrix name|matrix value
I prefer the second one....
Hello,If I wrote the next ebay (yes I know, yawn-snore) and I had a databasewith 5 million auction items in it, what would be a really goodstrategy to get a search done very quickly? Would it involvesomething called OLAP and/or "data mining"? The only technology I amfamiliar with is simply SQL Server databases with stored procedures.I think I'd be guessing correctly and say that this technology simplywouldn't be fast enough *on it's own* to do super fast queries againstmassive amounts of data.Any insights would be of great interest. Thanks.-Frameworker.

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,

Dear Sirs and Madams,
it's quite hard to find informations about OLAP mining I think. So I have some questions to you:
What advantages do I have by using Olap Mining instead of "normal" mining (relational databases)?
Is it just faster or are there other advantages?
What are the disadvantages? The data can be overaggregated (no detailled results), can not? Are there other disadvantages?
What problem do I have to face?
Whats going on with empty cells?
Thank you very much in advance and have a nice weekend.

Hi,
I am working with several tables, but for now I just mention 4 : one is fact table (named Usage), and 3 dimensional tables Periods, Products, and Regions. The fact table contains references to the dimensional tables. Table Periods contain two other columns month and year.
I created a cube containing columns from those 4 tables. Deployment was successful. Trouble comes when I want to create a mining structure using Time Series containing these columns :
- Period
- Amount (of money)
- Product name
- Region name
When I choose to use cube (instead of table) as source for mining structure, I'm forced to choose only one dimension (among the Periods, Products, and Regions). Whatever dimension I choose I end up being unable to use the column period as the Time-Key column. Effectively I cannot use Time Series method since I cannot use the column period.
(1) Why is this so [why Visual Studio forced us to use only one dimension from the cube] ?
(2) Why Visual Studio eliminates the column period, column that has relationship with the
time dimension?
(3) What is the use of Cube anyway to the mining? Is there still any use for it?
(4) What is the solution to that kind of problem I face?
Thank you,

Hi,
I know, this is a common OLAP Error, but In fact I'm having trouble with this while trying to process a DM Mining Structure.
I'm currently working on a website that gets data from its users and analyzes it using SSAS. The thing is each time we add a new "analysis criterium" (sorry I'm trying to translate our french BI language in English...), we have to build a new mining structure, which needs data about users who have actually answered the question associated with this criterium. Some times, there are thousands, and some other only dozens, which is the case for the structure I'm having trouble with.
I got only 2 hundred tuples in the learning set. So lots of the common criteria weren't filled: I removed them using a stored procedure before feeding the structure, so that I got no column with only "null" values.
Of course, I know that 200 learning cases is really not enough to build an accurate model, but the purpose was just a proof of concept for machine driven Mining Structure building, and that was supposed to work even with so few cases.
When I process the MS, it fires: (Sorry it's in french, translation follows)
Erreurs dans le moteur de stockage OLAP : La clé d'attribut est introuvable : Table : _x0032_0_EtudeIphone_Apprentissage, Colonne : EtudeIphone, Valeur : le nouvel iPhone (téléphone tactile et musical dApple). Erreurs dans le moteur de stockage OLAP : La clé d'attribut a été convertie en un membre inconnu parce que cette dernière est introuvable. Attribut Id de la dimension : 20_EtudeIPhone ~MC-Id de la base de données : ClassificationVDCE, Enregistrement : 2.
Badly translated it says "Errors in OLAP Storage Engine: Attribute Key not found Table:<StrangeTable> Column <MyPredictableColumn> Value <OneOfTheInterestingValues>
Errors in OLAP Storage Engine: Attribute key not found: converted to an unknown member. Attribute Id from dimension..."
Why? Too few cases? I have structures based on the same template but associated with other criteria and they work perfectly.
I'm ready to answer any question, and give any detail.
Thanks in advance.

Hi, all,
Just found that we are not able to define multiple key columns for a mining structure in SQL Server 2005 Data Mining engine, just wondering is there other way to define multiple key columns for a mining structure there? As in many cases, the table we are mining are with composite key consisting of different foriengn keys, e.g. A fact table are with transaction information and other foreign keys. If I am not able to define these composite key here for this fact table, I will have to have a named calculation in data source view to have a key column which is based on these original composite keys? Is this a better way to solve this problem or there is any other alternatives to figure it out?
Hope my question is clear for your help and I am looking forward to heaing from you shortly for your kind advices and help and thanks a lot in advance.

Hi, all here,
Thank you very much for your kind attention.
I got a quite a strange problem with Mining structure for OLAP data source though. The problem is: I am not able to edit the mining structure in the mining structure editor. The whole data source view within the mining structure editor is greyed. Could please anyone here give me any advices for that?

From Analysis Services, how do I now use reporting services to show the Data?
We saved huge log data from user behaviour in our site .
But In data mining time , we saw that most of them cant use for data mining
What is the best practice about data gathering from user movement in site?
is there any best practice Template for this ?
Hi everyone,
I posted a related thread before about this error below when I process a dimension. And seems that the solution by using "ClearCache" can not fingure out the issue when I want to process a mining structure...... .
OLE DB error: OLE DB or ODBC error: There is not enough procedure cache to run this procedure, trigger, or SQL batch. Retry later, or ask your SA to reconfigure SQL Server with more procedure cache.
; Sort failed because there is insufficient procedure cache for the configured number of sort buffers. Please retry the query after configuring lesser number of sort buffers.
Could someone please give me some suggestions?
Your help will be very appreciated:-)
Thanks^_^

Hi, all experts here,
I am a bit confused for the model evaluation (lift chart), should we map all the columns for both the mining structure and the case table? I mean for those predictive models, we have a predict column, shouldnt we ignore the mapping of the predictive column between the mining structure and the case table? But it seemes we are not allowed to miss the predictive column mapping between the mining structure and the case table.
Why is that? Could any experts here give me some explanation on that?
Hope my question is clear for your help.
Thanks a lot and I am looking forward to hearing from you shortly.

Hi,
I have a problem with a reporting services 2005 report.
The data source is OLEDB for OLAP 9.
The report contains all the members of a parent child dimension. An example of the implementation is defined in the post following the forum msdn:
Http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=138549&SiteID=1.
The report works fine in web. The problem is when the report is exported as Excel, the groups disappeared and the entire dimension is ragged down.
Normally toggled groups in reporting services are exported to Excel with the appearance '+' or '-' on the left side of the sheet. This feature is very useful to hide / show lines.
It seems that with the implementation specified in the msdn post above,
It is not possible to export correctly the report in Excel.
So my questions are:
Has someone already encountered this problem?
Are there solutions with a different implementation?
Thanks,

Hi guys,
Hopefully this is the right place to ask.
Basically we have have two larges databases, one of which is updated from the other monthly.
For exaplination purposes:
DB1 = Source DB
DB2 = Destination DB
The problem that I require a soltion to is, how do I insert rows from a table in DB1 to DB2 and recover and store the identity of the new row against the ID of the existing row. This is so that I can then matain constraints when it comes to inserting rows into the next table and the next and so on.
This process of storing the ID's as lookups will need to be done for almost every table of which there are 20.
The best Idea we have at the minute is to create a table with two colums for each table (drop it and recreate it after each table has exported) that contains the two ID's, new and old.
This will require using a cursor for each row in the existing table, inserting it in the new table and the using @@Scope_Identity to get the new ID and then insert the two values into the temp table.
This too me feels like it will be very slow, particuarly when I bear in mind how much data we have.
Does anyone have any better ideas? (Sorry if the explaination isn't great, its difficult to get accross)
Thanks

Hey gang,
I have ran into an installation issue that has been bugging me all weekend. I'm trying to run the preditive analytics query from a web based application (ASP.NET). I have installed a data pump as directed by this article "Configuring HTTP Access to SQL Server 2005 Analysis Services on Microsoft Windows Server 2003" because this isn't set up under a domain. I also set appropriate roles in Data Mining Database (set it to everyone for testing purpose).
ConnectionString is "MSOLAP.3;Persist Security Info=True;Data Source=http://1.0.0.1/olap/msmdpump.dll;Initial Catalog=DataMiningDB"

Dim connection As AdomdConnection = Me.Connect
Dim command As New AdomdCommand(txtQuery, connection)
Dim adapter As New AdomdDataAdapter(command)
Dim dataset As New DataSet
' Fill the dataset
adapter.Fill(dataset)
' Bind to grid
Return dataset
Catch ex As Exception
Throw ex
End Try
Return Nothing
Exception Details: Microsoft.AnalysisServices.AdomdClient.AdomdErrorResponseException: Errors in the high-level relational engine. A connection could not be made to the data source specified in the query.

It happens on the adapter.Fill(dataset). Any ideas?

Does anyone know if this is possible right out of the box in SSRS 2005 against an OLAP data source?
I have several parameters. My second parameter is to be filtered based on the first parameter (kinda like cascading), but how do I do this against an OLAP data source? Lets say I have param1 and param2 in a dataset. I want Param2 to show the locations only based on what I select in Param1.
Same but a little different: I have Parameter1 and then my second parameter (Param2) is a boolean (True/False). I want to show Parameter 3/Paramater 4 based on selection of Param2 (So, if true, show Param3, if false, show Param 4) and remember we are doing this in a sequence.
Can you do this thru SSRS? Any help would be great.
Thanks for your time in advance.
