I have SQL Server 2008 R2 on my computer and I want to use data mining with this version of SQL Server. My question is how can I do this? Because I've read some where that I can use data mining in SQL Server evaluation edition. I can use data mining in SQL Server 2008 R2?.
And I have one other problem when I want to use SQL Server 2008 Data Mining Add-Ins I can't connect to SQL Server and displays this error message.
Unable to connect to server 'localhost'. Please make sure user '' has at least read permission to some database on the server.
First you should get SQL Server Data Tools which runs in Visual Studio.
You will need Analysis Services installed; if you don't have it just run the SQL Server installer again and look for the option to install it.
After that you can take a look at this post I wrote a few months ago:
http://www.sqlservercentral.com/Forums/Topic480010-147-1.aspx
I wrote it specifically targeting the Neural Network models, but it contains details on several background steps you will need to do.
Finally - since you're using an evaluation version, you may want to just go for SQL Server 2012 (that's what I use, so I know it works).

We are having an issue with SQL Server 2008 R2 64 responding to stored procedure call. About every 2 weeks or so, the database stops responding to stored procedures called from an ADO connection/Command set (4.0 framework). We have been working on this for several months now, with little improvement.
System changes:
We upgraded an existing vendor product from SQL Server 2005 to SQL Server 2008 R2 via their upgrade method. The database instance moved from a 32-bit Windows 2003 Server to 64-bit Windows 2008 Server.
The pattern of failure:
The application is run throughout the day, executed by different users via Citrix without issue. Every few weeks, the application stops responding around the same time frame. Once the database stops responding to the hosted instance of the application, any execution of the procedure from the application hangs (installed on CITRIX server, installed on varied physical systems, or debugging in VStudio 2010). After an hour of checking logs, server status, SQL Monitoring tools, tracing the repeated execution attempts, the server decides to respond to the application without intervention.
Strange thing is, when the server is not responding to ADO.Net calls, we execute the stored procedure from SQL Server Management Studio and receive results in 1 to 2 seconds. We are using the same login to access SQL Server Management Studio, and executing the stored procedure with the same parameters.
Looking at the connection string passed to the ADO connection, I don’t see anything unusual:
connectionString="Data Source=myserver\myinstance;Initial Catalog=databaseName;Persist Security Info=True;User ID=xxxxx;Password=yyyyy;Connect Timeout=45"
Tried so far:
Added extra 2gb of RAM to the OS: no change
Added extra tempdb file, expanded size of tempdb log file from 1 to 5gb: reduced the issue from weekly to every 2nd or 3rd week.
Installed SQL Server 2008 R2 SP3: no change.
The black cloud:
To me, the repeating time pattern of failure implies an issue at the database host (server or resource), but the DBAs do not see load or resource issue. If it were purely a host issue, why does it respond to SQL Server Management calls, and not ADO.NET calls?
The last occurrence lasted over two hours, and was resolved after rebooting the database server. Not a great fallback, but desperate times and all…..
Updating the ADO.NET connection to use named pipes has resolved the issue for our application. Prefixing the database name with "np:" has the connection using named pipes.
connectionString="Data Source=np:myserver\myinstance;Initial Catalog=databaseName;Persist Security Info=True;User ID=xxxxx;Password=yyyyy;Connect Timeout=45"
The issue returned on 5/14. This query timeout posting gave us hints how to force SQL Management Studio to behave like the ADO.NET connection and allowed us to recognize this is a "parameter sniffing" issue. We have applied changes to disable the parameter sniffing within the stored procedure.
I have a SQL Server Express database that I would like to compare them to each other.
But I couldn't open them in Red Gate.
My question is: can I open SQL Server Express local db in Red Gate? (Red Gate required server name but I haven't)
I assume you are talking about Red-Gate's SQL Compare.
If so, here is an official list of what SQL Server versions they officially support:
Supported Versions
I would think you should be able to compare SQL Server Express editions, though for an official word, I would open a ticket with Red Gate Support.
Good luck!
We deployed a VB.Net application on a customer's computer that contains SSRS reports.
The application connects to the SQL Server database in the app without any problems. We installed SQL Server Data Tools so we could deploy the reports (rdl) and data source (rdl) files up to the report server. These deploy without any problems.
In SQL Server Data Tools we can "Preview" the reports without any problems as well.
We do run into a problem when attempting to view the report from Internet Explorer (run as an administrator).
We get the following error:
Cannot create a connection to data source 'DataSourceReports'
(this is the name we used for the TargetDataSourceFolder)
error:40 - Could not open a connection to SQL Server
We also get the same error when the app we deployed runs the reports.
Please let us know what is not set up correctly on the SQL Server side.
A likely possibility is that you are experiencing a double hop authentication problem. It's not clear from your explanation, but is the SQL Server database on a separate server from the report server? If so, then your credentials allow you to connect to the report server but Windows integrated security does not pass those credentials on to the SQL Server database if you are using NTLM on the report server. The report server tries to use Kerberos on your network to authenticate by way of ticketing to the SQL Server database, but you must have this configured correctly on your network. See this article if you want to use Kerberos: http://technet.microsoft.com/en-us/library/ff679930(v=sql.100).aspx.
Another (easier) solution is to open the data source on the report server and change the authentication to use stored credentials. Make sure the credentials you use have read permission on the SQL Server database. The downside of this approach is that you cannot use row-level security in your report by user unless you design your report to capture user information and set up the query or a filter on the dataset to restrict data by user. If that's not a concern, the stored credentials are easy to set up and maintain - and you're going to have to do this anyway if you want to use caching, snapshots, or subscriptions. For more information on stored credentials, see http://msdn.microsoft.com/en-us/library/ms159736.aspx.
I have sql azure database and to create and edit database using portal is very boring task due to it' user interface, when i will connect it with my local sql server R2 then i can not able to edit , create table from there.
Is there any way to make it possible , Please give me some solution for that
At this time, the two options available are the web user interface (which will be improved over time) and SQL Server Mgmt Studio (using queries; no user interface) for which SQL Azure support will also improve over time.
After all i found one 3rd party client to manage SQL Azure and that is RazorSQL- Awesome tool! I have write down about it in my blog, see here

I've been trying for quite some time to use Entity Framework with our IBM Informix databases. Hours of searching has pointed me towards installing the IBM .NET Data Server Provider, which I have installed, however when I attempt to add a new Entity Model to my project I only have the Microsoft SQL Server Data Providers listed. Am I missing a step? Is this even possible?
I am not an expert on Windows or .NET; treat any comments I make with due caution.
Installing the .NET Data Server Provider is an important first step. You now have to make sure that you can use it to connect to the Informix databases you want to manipulate. There are several things you'll need to check here:
Is the server (meaning the Informix instance) configured to allow DRDA connections?
By default, it probably isn't.
If you're the DBSA (database system administrator), you'll need to check that you've enabled 'drsoctcp' connections on the system, and configured a server alias to use that connection.
If you're not the DBSA, you'll need to chat with your DBSA to get the relevant information.
Assuming that you have DRDA connectivity enabled at the server side, you then need to ensure you have an appropriately configured ... DSN? Your client code needs to be able to connect to the server.
There is no reason I'm aware of why it cannot be done. However, I don't know exactly how to guide you step-by-step through any of the above.
You might need to seek assistance from IBM Technical Support.
You would help everyone if you clarified which version of Informix (the DBMS) you have, along with the version information for the platform where it is running (whether Windows or Unix, and the o/s version information) - and which version of the Data Server Provider you are using (and which variant of Windows you are using it on).
