Web Based Data Mining Query... Installation Issue..
Dec 4, 2006
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"
Try
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.
Errors in the high-level relational engine. A connection could not be made to the data source specified in the query.
OLE DB error: OLE DB or ODBC error: Login failed for user 'VMSQL2006IUSR_VMSQL2006'.; 28000.
It happens on the adapter.Fill(dataset). Any ideas?
I have also tried to set the olap application pool to use different identity instead of "Network Services", but I always get the same error message (but with user I specified instead of I_USR).
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.
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.
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?
- 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 am using Microsoft_Time_Series and have set HISTORIC_MODEL_GAP to various values (from 1 to 21). I always get this error: Error (Data mining): The 'HISTORIC_MODEL_GAP' data mining parameter is not valid for the 'My Time Series' model.
In Algorithm Parameters window, this parameters is not there by default, so I have to add it.
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 created a Market Basket Data Mining Model with Association Rules, which I want to query and show in a Report. Everything works fine, when I preview the result in the Reporting Services Data tab I see some sort of table which I can expand and then see the related products.
Unfortunately this result seems to be an ADOMD Datareader which I cannot place in a table, matrix or textfield.
If anyone knows how I can make this Informationen available in my Report please let me know.
With SASS Database i have created Data mining Structure Using Time series algorithm, while processing the SSAS db, Data mining  taking long time to process, so how we can  reduce processing time ???
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?
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?
I have problem using Data mining query task: when I want to set connection to Analysis services DB I don't see connections created in connection manager (they are not listed in the dropdown). (I can click on "New" and create new one but I already have one created in connection manager.)
Also, I want to make connections created in the connection manager flexible, easy to change after transfering package(s) to another server. How to do that?
I wrote a data mining plug-in algorithm in SSAS and now I am trying to view the lift chart in Management Studio. The studio gives the following error:
"The Data Mining Query builder control cannot be initialized due to the following problem: Deserialization failed: Multiple definition of element 'Column12' causes the content model to become ambigious. A content model must be formed such that during validation of an element information item sequence, the particle contained directly, indirectly or implicitly therein with which to attempt to validate each item in the sequence in turn can be uniquely determined without examining the content or attributes of that item, and without any information about the items in the remainder of the sequence."
I really do not understand what i did wrong. Can anybody help me?
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?
Hi, I'm new to this forum, so please bare with me.
I've created a mining model, i've tweaked it etc and i'm now happy with the results its producing. I'm now looking to automate the processing and exporting of the results of the model i've done this simply by creating an SSIS package with two tasks, one task being to process the model the other task is a Data Mining Query task.
This package works fine in visual studio and when i deploy it to the server.
The problem i'm having is when i then try to execute the package from a job, after a bit of investigating i have tracked it down to the Encryption of "sensitive" properties. By default the encryption is based on UserKey which is why the package works for me when i execute it from VS or even the server, but when the job trys to execute the package running under the sql agent account it fails.
Looking at the security options i have for packages, i can either DontSaveSensitive, EncryptSensitiveWithUserKey or EncryptSensitiveWithPassword plus a few others.
DontSaveSenstive is clearly not an option as this just creates an unusable package.
EncrptSensitiveWithUserKey doesn't seem to be an option as the job runs under the SQL Agent account (also i'm thinking that the UserKey that the encryption is based on also incorporates other factors related to my profile that i can't impersonate? i might be wrong though)
EncryptSensitveWithPassword seems to be an option except that i can't get this to work either, there doesn't seem to be anyware in the job step to give it the password information.
Its frustrating me now because i've fallen at the very last hurdle, if anyone else has experienced this problem and knows how to resolve it that would great.
I have an error message I was wondering if anyone else has seen and resolved. When I open excel and click on the query wizard on the Data Mining Ribbon, I get an error message that says "Input String not in Correct Format"
After I close this dialog box the 'Welcome to Query .... ' wizard will open, but when I select the Advance button my process aborts due to the input string error.
I have only ran association models on the computer.
The Manage Models and Browse buttons work fine.
The error came up on Friday, but it wasn't there on Thursday. There were no changes done to the machine (no installation of new software).
I have tried reinstalling the add-in.
Thank you all for your help,
Davy
I have pasted the SQL syntax below that I get from the error dialog box after the query wizard closes.
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

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.
I'm trying to query data from a database for a report that looks for the last 2 weeks starting at 10pm, taking a value once every 24 hours. Using
AND DateTime >= DateAdd(wk,-2,GETDATE())
AND DateTime <= GetDate()") I easily get the last two weeks but the query obviously only grabs the data at the time the query runs. I need to be able to run it any time of the day but only grab the data at 10pm. I'm very new at this so please excuse my ignorance but I could really use some help with this. Thanks very much.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
hi, i am generating report for my project. my table goes like ID VASID VASSID JanMail JanVisit JanPhone JanComment FebMail FebVisit FebPhone FebComment................. DecPhone 1 25 4 True False False Mail me False True False Visit me
My report has 3 check boxes for Mail,Visit,Phone respectively and a listbox of 12 months january-december respectively.. once user check on Mail and select a month suppose January in my report,the report should generate only January Comments. here user can select any number of months.if user selects january,february and march, report should generate respective months Comments. Please help me in writing SQL Query to get the comments.......
if any one know the solution for the above problem,Please help me
I am trying to write a query that will be able to select different segments of data based on spelling of the last name.
For example, in my database of name information, I need to select anyone whose last name starts with 'AAA' to 'EJJ'
then need to select anyone whose last name starts with 'EJK' to 'JAE' and so on...
I have tried using LIKE and some other methods with the > operator, but I can't get it to work. Does anyone have any suggestions or ideas on how to select data based on the alphanumeric characters this way?
FirstName | LastName  | DateofBirth ----------------------------------------  Thomas  | Alva Edison |  10-10-2015  Benjamin | Franklin   |    10-10-2015  Thomas  | More       |    11-10-2015  Thomas  | Jefferson  |   12-10-2015
Suppose today's date is 09-10-2015 in (dd-MM-yyyy format), I want to perform a query in such a way that I should get the data from the table above WHERE DateofBirth is tomorrow, so I could get the following result.
FirstName | LastName  | DateofBirth ----------------------------------------  Thomas  | Alva Edison |  10-10-2015  Benjamin | Franklin   |    10-10-2015
I am trying to delete tables from data where the ModifiedDates older than 9 years in AdventureWorks2012 database . I get console notified that foreign keys are dropped but the delete statement is throwing errors. I am sure that somewhere the key constraints are not getting altered, but i'm not able to figure it out as i'm a relative beginner to T-SQL. The error and code:
The DELETE statement conflicted with the REFERENCE constraint "FK_SalesOrderHeaderSalesReason_SalesReason_SalesReasonID". The conflict occurred in database "AdventureWorks2012", table "Sales.SalesOrderHeader [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null $option_drop = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions; $option_drop.ScriptDrops = $true;
I am wondering is there any way to select only a portion of a data set to train the mining model? In this case, I mean we dont need to split the dataset in advance, what I want to do is being able to select any random portion of a selected dataset to train a mining model. Any advices?
I am looking forward to hearing from you and thanks a lot in advance for your advices and help.
hi I am new at MSSQL 2000 DBA thing. and trying to learn more about analysis service/data warehouse/data mining. so is any expert out there can Recommend some good books or web link article to read? Thanks
I would like to transfer selected data from an ODBC-based table to a OLEDB-based table. However, there isn't a data flow source on the Data Flow Design screen to accomodate such an action. Please help!
I'm stucked in a problem and I thought if you would be so kind as to helping me to resolve it.
I'm implementing a clustering algorithm plugin for text mining. I've already read the tutorials and sample codes provided by the MSDN Library.
Well... My problem is: I can't go through the data when the Predict method is called. I've read that this method implements the "core" of the custom algorithms. Here is a small snippet of my code for you to understand my doubt:
As you can see, I'm going through in_rgValues to get its values, but i'm only obtaining the first register of the table on the database. I need to roll over a kind of resultset so I could access all the registers I need. Is there any way to do so ?
I expected Predict() received a matrix containing all my data, but the only thing I noticed that could represent the data is that in_rgValues vector. So I can go through this vector, but it holds only the first register of the table in the database (that's what's being saved on my log). I need all of the registers in order to pre-process the data and implement my clustering algorithm.
Well... That's it... I would be very pleased if you could help me.
