Mining Structures
Aug 23, 2006
I am using the wizard to create a new mining structure and getting the error at the time of selecting the datamining technique like either microsoft decision tree or microsoft timeseries etc.,
"Unable to retrieve a list of supported data mining algorithms. Make sure you are connected to the correct Analysis Services server instance and the Analysis Services server named localhost is running and configured properly. You can continue with a default list of data mining algorithms."
What is that means?
Thanks in advance,

Hi!
If you make an view you can script it in SSMS and get the DDL.
How to do something similar with mining models/structures getting DMX?
I see you easy can get XMLA, but I would prefer the "dmx-ddl"...
Thanks

Still new to DM and SSIS...anyand all help is greatly appreciated!
In SSIS they say that you can use the Analysis Services Processing Task to process a mining model/mining structure, however, I do not see where you can give it a relational table to work off of. I know that I can use a data flow to do this but I wanted to go a different route if I could to process my models as I don't really necessarily need the data flow as what I am tring to do is pretty simple.
That brings me to a more general question, what is the best method for training your models using SSIS? I am building a new model everytime the package runs using some variables and the DDL task, running a query on it, and destroying it at the end of the package but I am having logistical problems training it outside of the data flow. I tried using the DM Query task but it requires that you output a result set and I am not sure if I can use it to create and process models.
I would think that they would just give you a DMX task similar to the SQL task but that does not seem to be the case. Also, when I browse the AS objects via the processing task I can only see the mining structures and not the mining models.
Am I just missing something here?
Cheers,
Dan Meyers

Hi, all here,
I am wondering where can I store my mining results in data mining engine? For example, I got mining results like accuracy chart, decision trees, and other formats of results based on different mining algorithms I used for my data mining, so where can I actually store the results for reporting service use later? Is it possible to do that in SQL Server 2005?
Thanks a lot for any help and guidance in advance.

Hi,
I have just run a simple data set through a model to predict a simple true or false value (i.e. binary output)
The Lift Chart/Mining Legend in Analysis Services shows three results €“ Score, Population Correct (%), and Predict Probability (%)
Population Correct I beleive is the percentage of predictions it got right out of the total number of predictions it tried to make. Is this correct?
However, I can€™t work out how the other two are derived in particular the 'SCORE'. To give a live example the scores were as follows:
Model Score Pop Correct Pred Probability
Decision Trees 0.83 76.59% 54.28%
Neural Network 0.75 67.63% 50.05%
Ideal Model 100.00%
Can anyone help with this and give a detailed explanation?
Many thanks,
S Rajput

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?

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.
Best regards,

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,

I followed the tutorial posted at [URL] ...
Everything was ok until the last step where I had to process the mining structure which resulted in a warning
"Informational (Data mining): Decision Trees found no splits for model, Tbl Decision Tree Example."
What does this error mean? How do I resolve it? Also, I only see the first level in the Mining Model Viewer, I don't see the levels 2 and 3.

Hi, all experts here,
I would like to know if there is any way to migrate third-party data mining packages with SQL Server 2005 data mining algorithms together then we can have a comparison among all of them to get the best results for training models.
I am looking forward to hearing from you.
Thanks a lot.
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:Â
"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?

Having successfully created :
- a data mining structure with about 80 columns.
- a data mining model using Microsoft_Decision_Trees with 2 prediction columns.Â
I thought I would then explore the possibility of have more than 2 prediction columns, in this case 20.
I get an error message and I can't work out :
a) if this is because there's a limit to the maximum number of prediction columns and where that maximum is stated.
b) if something else has become corrupted
c) there's a know bug and if the error message is either meaningful or not.
Either way, I'm unable to complete the data mining wizardÂ
The error message is :Errors in the metadata manager. Either the mining structure with the ID of '[my model Structure]' does not exist in the database with the ID of 'DMAddinsDB', or the user does not have permissions to access the object.

I have 2 test database identical in size and table structure, only one resides on filegroups and one resides on a single file.
From everything I have heard filegroups are suppose to improve performance. I stop and start the server before each test to clean out
cache. When I run the filegroup test initially the first run averages 20 seconds slower then the database sitting on the single file. However
on consective runs there is a significant improvement in performance with filegroups verses single files. I have
the indexes sitting on a separate filegroup and 2 additional filegroups to spread the tables across. Does any one know what would be causing
the performance to degrade on the initial run of the test. (The test by the way is a stored procedure that runs a select statement against each table).
Any Info Will help Thanks

Hi,
i'm writing a app in c# and have to store Trees in a Database.
I'm working with Datasets for the exchange between the DB and the App.
The trees have the same options like the windows folders. If u delete a node, all subnodes should be deleted too.
But something a Foreign Key from ParentID references (Id) with the delete-Rule on cascade seems not to be possible, because of multiple cascade Paths or cycles. Do i have to add some xtra constarins:
Not Possible:
create Table tree (
Id varchar Not null,
ParentId varchar Not null,
Constraint pk1 Primary Key (Id),
Constraint fk1 Foreign Key (ParentId) references tree(Id)
On Update Cascade
On delete CAscade
)
Do i have to write triggers, which delete The subnodes too and set the Update-/deleterulr on NO Action

(Wow; surfing this site has really illuminated what a lowly hack-programmer I am to this field of SQL and relational processing :S )I am creating a temp table, doing an Bill of Material explosion for a single Order Line Item.(note: SQL Server 2000)I used blindman's "accumulator method (click here) (http://www.dbforums.com/showpost.php?p=6239109&postcount=6)" to generate the entire potential BOM tree.So; step 1 works wonderfully! :beer: Cheers blindman!Now; I want to remove unwanted nodes (and all their children) from the temp-table. I have a bunch of functions (0 to 1 for each node) that return a Yes or No. If "No", then flag-to-eliminate immediately that branch and don't revisit anything on it (and therein lies my problem). This will leave me with a temp table of only valid nodes.Since this is recursive, and since it will involve Dynamic SQL (the function name varies), all I can come up with is using a Cursor in a WHILE loop. Even at that; since a CURSOR is point-in-time (ie: values don't change once selected), I'll have to re-check the current temp table values (or create of 2nd temp table of only deleted nodes and repeat a SELECT with NOT EXISTS in it, hmmm).Since blindman's method generates a table ordered by level, the sequence of processing is pre-determined - unless I can re-order it into a more traditional hierarchy (1 entire branch at a time) and number the levels, in which case the cursor could just skip to the next branch of equal or higher level.Note: The thought does occur to me I could have an intermediary function (static name) that in turn does the Dynamic SQL. These functions contain the Business Logic that looks at a myriad of column values and relationships in the database and there's no one-size-fits-all decision tree so Dynamic SQL is necessary.The max cursor size will be maybe 300, and on average 100. Number of levels will normally be 3 or 4, but conceivably could be up to 10. Given the average 100 potential components/sub-assemblies, the final assembly will be about 30. As a periodic background process; it will do 3,000 Order Line Items a day, so I'm figuring 1 second response time per build is adequate (ie: the user's not waiting on it so it doesn't have to be blinding fast) - however why waste?Anyhow; I thought this might be a fun problem for some Data Structure genius who wants to give a lesson in Relational Programming.Thanks for looking.Here's what I have so far:CREATE PROCEDURE dbo.sp_ExplodeTest1 (@recID int = 1) AS/* tbTestH is a table containing an assembly hierarchy. Assemblies with no parent are Builds.Assemblies with no children are Components.It's columns: MyID int, ParentID int, (other descriptive columns)*/declare @t table (TempNodeID int identity(1,1),MyID int)-- Seed the tree with the Build's ID.insert into @t (MyID) values (@recID)/* This populates the temp table with the entire Assembly for the given build. It is Ordered By the level in the assembly. Number of assembly levels is infinite.For example: Level 1 = the Build. It comes firstLevel 2 = all parents are level 1. Is next (no particular seq)Level 3 = all parents are level 2. Is next (no particular seq)etc.*/while @@Rowcount > 0insert into @t (MyID)select tbTestH.MyID from tbTestHinner join @t rList on tbTestH.ParentID = rList.MyIDwhere not exists ( select *from @t CurrentList where CurrentList.MyID = tbTestH.MyID)-- now to display the results so far.select t.*, tbTestH.* from tbTestH inner join @t t on tbTestH.MyID = t.MyID order by t.TempNodeIDGO

I have used DBDIFF(from DKGAS.com) ChangeManager from Embarcadaro and SQL COMPARE from Redgate.
I did have have some problem in each of these tools AND am looking for some good tools which are economical also.
Thx in advance

A point for general discussion maybe.
I've just read Jeff's query regarding passing an array to a stored procedure, and it seems to be a question that hits the message board quite frequently. There often seems to be the case where you have some block of data in one location, and want to process it somewhere else, and there just isn't an easy way to do it (or is there?). Passing a cursor is possible, but getting data back out of a cursor is painful.
The ways I have used in the past are:
Using a cursor
Using a global temporary table
Using a "permanent" table, but declared with a unique name (using a timestamp) and passing the tablename as a parameter.
Has anybody any suggestions for a future SQL release which we could suggest to Microsoft?
Suggestions from myself:
-Having a single TSQL command to copy a cursor back into a table, to make cursor parameters less cumbersome
-Being able to pass a pointer to a temporary table as an SP parameter
-Allowing variables to be declared with more complex structures (such as arrays, or classes)

ChrisH

Hi, I have a table of folders that I would like to be able to displayin a depth first manner, similar to what you would see in WindowsExplorer. the table is defined similar toCREATE TABLE Folders (folderID int,parentFolderID int,name varchar(32)).... I've left some things out of the definition for the simplicity ofexample.My desire is to quickly generate a record set containing the all childfolders of a specific folder along with the how many levels deep eachfolder is, in a quick and memory efficient manner. I have done someresearch through this group and found a few examples similar to what Ihave hypothesized, however I was hoping for some feedback on what Ihave decided to use.Since this database table is already created and I cannot modify theexisting schema, it would not be very feasible to use a nested setsmodel (unfortunately -- or if anyone has a suggestion?).I plan on using a stored procedure that recusively calls itself.something similar to the following:/* This is assuming the table #TempFolderTable has* already been declared globally*/sp_FolderDisplayRecurive @folder int, @level int ASIF @@NESTLEVEL > 31 RETURN;DECLARE @childFolder INTDECLARE folders_cursor AS CURSOR LOCAL FORSELECT folderID FROM FoldersWHERE parentFolderID = @folderIDOPEN folders_cursorFETCH NEXT FROM folders_cursorINTO @childFolderwhile @@Fetch_status = 0BEGIN-- Insert current folder into-- folder table (under parent @folder)INSERT INTO #TempFolderTable(FolderID, DepthLevel, ParentFolderID) VALUES(@childFolder, @level, @folder)-- Iterate over all of its childrenEXEC sp_FolderDisplayRecursive@childFolder, @level + 1FETCH NEXT FROM folders_cursor INTO @childFolderEND...Will this incure a large overhead for a deep directory structure? Arethere any other problematic issues? Any suggestions and/or commentsare very welcome. Thanks!

Let us suppose that I have two similar databases and need to create ansql-script upgrating one database structure to another. For example, thesedatabases are from different versions of some software, first is from earlyversion, next is from current, and second one contains several new tables,sevelal new fields in old tables, several new or changed stored procedures,UDFs and so on.How to solve this problem using standard tools?

Hi All,
I have 2 tables in different database. I need to compare the tables structure and insert the fields if not existing.
Ex:
I have 3 fields in table1.(database name Pubs)
Table1
F1
F2
F3
I have 2 fields in table2.(database name northwind)
Table2
F1
F2
I need to insert the table1.F3 into Table2. Basically i need to compare all the fields with table1, if not exist in table1 i need to insert that field into table2. I am using SQL Server 2000. Please send me the code.
Thanks,

I'm wondering if anyone knows of a good site to find open source database structures (such as ERD's, scripts, or something of that nature)?
I think I have a pretty good handle on database design, but it would be nice to have a resource like that so that I can compare the design of my DB to DB's that people (smarter and more experienced than me) have created for similar purposes.
What I'm thinking of is a site like Open Source Web Design (www.oswd.org) for Databases. Anyone know of anything?

Implementing data mining Add-in in an academic setting? We need to handle over 150 new students a semester and have their connection to Analysis Services survive for their four years at the college. We are introducing data mining to every freshman business student as a unit within their Intro to Excel class (close to a month of work to give them a sense of what is possible). Other courses later in their curriculum will expand on that introduction.Â
Once implemented, we would have as many as 900 connections to manage (four years from now). It is possible that multiple sections will be running at the same time, so 40 students may be accessing the data mining tools concurrently. Â
Is there a way to "bulk establish" the access credentials and establish those databases?

I am having a hard time finding materials on this subject. I am guessing I am using the wrong keywords to search. Basically, I want to be able to modify database tables through a web form. They can add columns and delete columns through the form. I would just want to default the type of column and the length. I am sure it has been done, I was just wondering if anyone had some resources they could throw my way. I would appreciate it. Thanks.
