Data Mining :: Deleting Old Data From Adventure Works 2012 With Powershell
May 3, 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 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.

Hi, all here,
Thank you very much for your kind attention.
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.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

Hi all,
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.
Any tip will be greatly appreciated.

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?

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.

Hey All,
I'm new to the whole DB thing so I wanted to start off easy and download SQL Express. That part worked fine so I tried to install the Adventure Works DB to get some practice using the SQL commands. The problem is every time I click on a table in Adventure Works and choose Open Table I get a Microsoft SQL Server Management Studio box that pops up. The error says: Class Not Registered (Exception from HRESULT: 0x80040154 REGDB_E_CLASSNOTREG))
(Microsoft.SqlServer.SqlTools.VSIntegration)
Help!! Any ideas out there how to get the Adventure Works DB working? Thx much.

I have found a bunch of duplicate records in our housing database that ideally I need to delete.There are two tables that I need to remove data from ih_cml_log_entry and ih_cml_log_notes. There is no unique identifier between the tables for a log entry. So I have had to join on the person_ref, log_seq and the date/time of entry.How do I go about deleting the data - I've used the script below to identify what I need to delete -
SELECT *
FROM
(
select cml.person_ref, cml.open_date + open_time as 'datetime',cml.open_user,cml.log_type
,ROW_NUMBER() OVER (PARTITION BY cml.person_ref, cml.open_date + cml.open_time,cml.open_user,cml.log_type ORDER BY (SELECT 0)) AS RowNo
,n.note

Hello Everyone,
I am very new to SQL and just completed an install of SQL 2005 Express. After install, I downloaded the Adventure Works database and attempted to attach through both the Object Browser (right-click 'Databases'--->'Attach') and by running the script that is located on the SQL download page where I got the Adventure Works db.
Here's the error that I get:
"Could not find row in sysindexes for database ID 8, object ID 1, Index ID 1. Run DBCC CHECKTABLE on sysindexes."
I have attempted to go through the help files, but unfortunately the above message is too cryptic for me and I have no idea what it's telling me.
Can someone help?
Thanks!!

I was studying the Adventure Works database because I read it contains good examples of best practices.
It has an ID column for each table that is auto-incrementing Primary Key. There is also a row guid which seems redundant since the ID PKs are identity columns that increment automatically and should be unique in a given table.
What is the purpose of the row guid being used in conjunction with the ID which should be unique in a given table?

All,
I'm running Windows Xp Pro With SQL 2005 Dev edition with Adventure Works sample db installed. I am the local administrator on my desktop, the services are up and running and I specified local connections only since this is the DEV edition of SQL05.
When I try either one of these connection strings: Data source=(SQLDEV05); initial catalog=AdventureWorks or Data source=(local); initial catalog=AdventureWorks.
I receive this error message:
TITLE: Microsoft Report Designer
-----------------------------
A connection cannot be made to the database.
Set and test the connection string.
----------------------------
ADDITIONAL INFORMATION:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)

I have deleted nearly 30 million rows from a table. But however when I used the sp_spaceused command to calculate the data occupied by the table I don't see any difference in the data size of the table. In fact the data has increased to few MBs after the deletion, but not much.

I am trying to create a Adventure Works Tabular cube in my developing machine and im having problems deploying the tabular cube (the DW database was firstly attached without problems)
So I'm having problems processing Adventure Works Tabular Cube, the problems are somewhere between SSAS project configuration and running privileges, i think. I'll describe exactly where i am:
- in SSMS 2012, connections, tables and roles and roles are empty, i only have the full name of the database when I try to process i get an error "the table with id of "product category 92583829......", Name of Product Category refereced by the model Cube, does not exist. An error ocurred when loading the model cube, '?c:program filesmicrosoft
sql serverMSAS11.MSSQLSERVEROLAPDataAdventureWorks Tabular model SQL 2012.0.dbModel.21.cub.xml'. (Microsoft AnalysisServices.)"
- in SQL Server configuration Manager, I have
Sql Server (MSSQLSERVER) running with account NT ServiceMSSQLSERVER
Sql Server Analysis Services (MSSQLSERVER) running with account .L.ABCDE , which is my account, i've changed because i've read somewhere that i could have problems with privileges.
(Note: it's strange because SSAS is tabular, i can see a blue rectangle (sort of) in SSMS but in configurator manager seems to be a cube.)
- in SSAS Project i unzip a clean copy of the project and the first error is that BIM file can't be found, it try's to find server TOSHIBA_S50_BTAB, but as i have only tabular SSAS running, i replace for TOSHIBA_S50... And some time ago it worked, now it doesn't even found TOSHIBA_S50_B?!!!!

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?

Hi
I have three questions about several topics.
In this code:
public string ConnectionString
{
get
{
return "Provider=MSOLAP.3;Data Source=localhost;Initial Catalog=Adventure Works DW";
}
}
What is data source and initial catalog and what does this code do? And if I want to use other database how can change this code? (This code is for data mining viewer client project)
And in this code:
SqlConnection cn = new SqlConnection("Data Source=localhost;Initial Catalog=AdventureWorks;Integrated Security=True");
SqlCommand cm = new SqlCommand("Select AddressID,AddressLine1 from Person.Address", cn);
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cm;
DataTable dt = new DataTable();
da.Fill(dt);
this.comboBox1.DisplayMember = "AddressLine1";
this.comboBox1.ValueMember = "AddressID";
this.comboBox1.DataSource = dt;
what is comboBox1.DisplayMember and comboBox1.ValueMember ,and what is difference between those ?
and other question:
in adventure works dw project for data mining predicting ,in forecasting model ,if I want to show the result of this query in the combobox in c# how can I show that?
SELECT
PredictTimeSeries(amount)
From
[Forecasting]
And again in this code ,it has a result which has two culomns ,on of them is for amount and other column is for time ,in sql I can save this result in exsiting table or neew table with wizard,but I want to
Do this work in c#,that€™s mean with a adomdconnection I connect to forecasting model and write this query then in a datagridviwe ,Iwant to see the values of prediction in adventure works dw database.
Other question:
In €œdataminingviwerclient€? project I change this code and you can see it,for this code I have a form that give servername and catlogname in that and then with clcking on a button I want to show the chart of model in a child form ,but I can€™t.
public Form1 form1 = new Form1();
public string m_ServerName;
public string m_CatalogName;
public Form3()
{
m_ServerName = "";
m_CatalogName = "";
InitializeComponent();
}
public string ConnectionString
{
get

MiningService service = null;
// Clear any existing controls from the panel
if (panel.HasChildren)
panel.Controls.Clear();
// Connect to server
conn.ConnectionString = ConnectionString;
conn.Open();
// Determine the viewer type based on the model service and
// instantiate the correct viewer
model = conn.MiningModels[modelName];
service = conn.MiningServices[model.Algorithm];
if (service.ViewerType == "Microsoft_TimeSeries_Viewer")
viewer = new TimeSeriesViewer();
else throw new System.Exception("Custom Viewers not supported");
// Set up and load the viewer
viewer.ConnectionString = ConnectionString;
viewer.MiningModelName = modelName;

panel.Controls.Add(viewer);
viewer.LoadViewerData(null);
}
catch (System.Exception ex)
{
MessageBox.Show(ex.Message, "Model Load");
}
conn.Close();
when I run this code ,I have one error that say: the €œ object not found parametr name:index
Please see this code and answer my question.
If you just can answer one of my qestions ,please say.

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.

Hi, all experts here,
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.
With best regards,
