I'm trying to change the datasource of a SQL Server LinkedServer using SMO
I've got the relevant linkedserver as an object, changed the DataSource property, and selected it again to confirm the change.
However, the change is lost as soon as the object is destroyed.
Looking at BoL I think I need to be using alter() method of the linkedserver class but I just get an error
Alter failed for LinkedServer '<servername>'.
any ideas how I should be using this class to do what I want?
I can post my script (PowerShell) if it would help.
So I'm trying to run through a directory of reports and change the data source of every report from whatever it has now, to a shared data source. I'm using C#.
If I understand the process correctly, I want to .GetItemDataSources on the reports service and store it in an array of datasources. Then I want to Change the name and reference of the datasource to match something that I alredy have elsewhere. Here is the code...
System.Web.Services.Protocols.SoapException: The data source 'SummerOf70' cannot be found. ---> Microsoft.ReportingServices.Diagnostics.Utilities.DataSourceNotFoundException: The data source 'SummerOf70' cannot be found. at Microsoft.ReportingServices.DataExtensions.DataSourceInfoCollection.CombineOnSetDataSources(DataSourceInfoCollection newDataSources) at Microsoft.ReportingServices.Library.SetItemDataSourcesAction.SetReportDataSources(CatalogItem item, DataSource[] dataSources) at Microsoft.ReportingServices.Library.SetItemDataSourcesAction.PerformActionNow() at Microsoft.ReportingServices.Library.RSSoapAction`1.Execute() at Microsoft.ReportingServices.WebServer.ReportingService2005Impl.SetItemDataSources(String Item, DataSource[] DataSources) --- End of inner exception stack trace --- at Microsoft.ReportingServices.WebServer.ReportingService2005Impl.SetItemDataSources(String Item, DataSource[] DataSources) at Microsoft.ReportingServices.WebServer.ReportingService2005.SetItemDataSources(String Item, DataSource[] DataSources)
I know the DataSource is there.
Am I going about this all wrong? Should I delete the datasource first and then create a new one?
I look forward to clarifying my poor grammar. Thanks in advance!
I have to create a script for changing the datasource at runtime.
Here is my screnario, While development I am using Data source name called "DevDatasource1" and when I am deploying it to other evnironment the datasource name will change let us say "QADatasource".
I have to create a script for changing the datasource(i.e. DevDatasource1 to QADatasource). How I can achieve I this using the setItemdatasource?
I have 2 servers one has SQL 7.0 running on NT4.0 and another has SQL 2000 running on W2K Server. I have established a linked server for SQL 2000 from SQL 7.0.
I don't have any problem of creating linked servers for sql 2000 from sql 7.0. I am also able to create linked server logins to access the sql2000 tables. Even I am able to see the tables on the Databases.
Im sorry if im in the wrong section. My problem is a very common one and it has been hard for me to find the fix.
Ive gone thru Component Services, Firewall settings, Registry and Microsoft Sites, but to avail.

I'm copying almost all contents of one table from one server/db to another. In relation to speed, what is the difference of using SSIS vs a linked server and sp? I'm going to do the benchmarks, but I'm curious about behind the scenes kinda stuff, theoretically which one if any should be faster and why?
Hello All, I created two database instances in the same MS SQL SERVER 2005 named hafeez and local. I created a linked server from hafeez database to local named HTOL
I created a dummy table in local database named samplocal.
Now i am able to list the records using the linked server, for this i used the following query.
SELECT * FROM OPENQUERY(HTOL,'SELECT nameandval FROM SAMPLOCAL');
Now the problem is, i am not able to insert the rows into the samplocal table using linkedserver. I am using the following query to insert the rows and getting the following errro.
INSERT INTO OPENQUERY(HTOL,'SELECT nameandval FROM SAMPLOCAL') VALUES('tertertetttwertw');
Msg 7356, Level 16, State 1, Line 1 The OLE DB provider "SQLNCLI" for linked server "HTOL" supplied inconsistent metadata for a column. The column "nameandval" (compile-time ordinal 1) of object "SELECT nameandval FROM SAMPLOCAL" was reported to have a "Incomplete schema-error logic." of 0 at compile time and 0 at run time.
Is the above query correct? or shall i miss anything?

I am not expert on SQL server, i need to be able to access different server from withing sproc,
1. Is Linked Server is the best aproach.
2. If yes then how i set it up that it take all authenticated users of this server to remote, i tried with impersonate but it gives error that NT authority dont hae access etc etc (when i try run a sql that accesses remote server)
3. The reason i need to access remote server is ... one of the that table in my db (logTable) is getting to big it is 10 times the size of rest of the db altogether so i though i move it out not just from same db actully put it on a seprate server. so that all the tasks about main db would become easy etc.
We currently have an application that primarily sits on SQL server and needs to access some legacy data in a DB2 database. The solution we are using is to use a linked server between the two servers. The problem with this is that complex queries occasionally cause the driver to fetch a complete table and filter that table locally. I wondered whether service broker (which I have never used) could allow me to access the DB2 database using MQSeries and thus speed up the application as our ODBC calls have low priority on our mainframe.
Thanks and sorry if this sounds a stupid use of service broker.
When running a query with a table from another SQL7 Server that is linked, if only 1 table from each server is specified, the query runs fast and returns only the data rows needed from the linked server. When another table is added on to query (on the server running the query) the query processor tries to run a remote query and return over 400,000 rows over the network. Any suggestions?
UPDATE OPENQUERY(LINKEDSERVER, 'SELECT START_ORDER_NO FROM "OECTLFIL" WHERE "FILE_KEY" = 1') SET START_ORDER_NO = 0
----The START_ORDER_NO field contains a 48
SET START_ORDER_NO = 1~9
----The START_ORDER_NO field contains 49~57 respectively.
SET START_ORDER_NO = 10 ---The START_ORDER_NO field contains 12337 SET START_ORDER_NO = 11 ---The START_ORDER_NO field contains 12593 SET START_ORDER_NO = 12 ---The START_ORDER_NO field contains 12849
incrementing by 256 as I increase the value passed...
ASCII 48-57 are the characters 0-9. The string '10' consists of the two bytes with the values 49 (0x31) and 48 (0x30). It is being viewed in reverse byte order as the value 0x3031 which equals 12337 (48*256 + 49).
The LinkedServer is Pervasive SQL 2000i using 'OLE DB Provider for ODBC'
The START_ORDER_NO field is a Numeric(8,0)
I'm thinking some kind of Unicode, or translation or code page issue, but I haven't had any luck yet.
I'm not sure how difficult this is, I don't think I'm a neophyte but I'm feeling like one...
I working on a form using an SQL DataSource. I am going to add a where clause. In that where clause a value from a label will be passed from the user. How do I pass to the HTML Source the label value from the where clause. The value can change from user to user. Sample below: SELECT [KeyRolesID], [KeyRolesDesc] FROM [KeyRoles] WHERE ([JobCodeFamily] = @JobCodeFamily). I want to replace the @JobCodeFamily which is currently coded with a value from the Sql DataSource in the design form with a label value entered by the user.
but it doesn't work, I tried use a pure asp.net web service and it works. can anyone help me to set the connecting string for datasource and query for dataset when it using wcf as the web service? Thanks in advance.
I have a question about the datasource that we create on the Report Manager. What is it used for? In the below connection string which is given in the "Connection String" text box of a datasource link:
What is this datasource used for? Is it used only to use the ReportServer database or even our queries incorporated in the RDL files will be run against this datasource? I think the latter should not happen because while creating RDL files also, we provide a connection string to run the stored procedures against that datasource.
Please let me know about the same.
Thanks a lot and let me know if the question is not clear.
I have this web store that I have been creating. When a customer goes to check out, he has to log in, then he is redirected to a page where he can view/add/or edit shipping and billing address. I have based all the sql statements on the profile username, adding records and retrieving them works just fine. When I go to change something in the info it uses an sql statement that updates based on "Where AccountUserName = @AccountUserName", I have @AccountUserName set to Profile("Username"). Keep in mind this works fine for adding new or bring up current records. I even put in code in the updated event for the sql data source to post a msgbox telling me how many rows were affected, it says 1 even though I dont see any change in the data. What am I doing wrong here, it's driving me nuts, its just a very simple update.
My god.All I want to do is post the contents of a web form to a database sql express 2005 or access using C#. Why can I find nothing for this very simple process online?Can you tell I am totally frustrated? So lets say i have a few text fields and I want to click submit and have that entered into a table. I use C# for code behind. So I can do basic C# programming and I can to webforms with visual web developer 2005 dragging and dropping for textboxs and a button to the aspx page. But then the mystery begins for me. How the hell do I simple post that form data to the table. I understand connection string basics. I aslo can design and create tables. But tying this all together is becoming a problem. I don't want to use gridview formview detailview or any of that canned UI stuff. I also don't understand VB and when I see VB examples they only cloud my already cloud ASP.NET world. Please help by posting examples, and maybe some links or books to add to my newbish collection. Thanks,Frank
Lets say I have a Sqldatasource that uses the following SelectCommand="SELECT category,name FROM table". How do I get the value on category from my datasource in code behind if I know that my selectcommand always will return one row? Can I write something like datasource.items["category"].Value? Thanks for your help!
Hi there, I'm using a Repeater at the moment which is bound to a SQLDataSource. I expect much load on that Website, should I choose another DataSource? Which other DataSource is better if it's about Performance? I read some stuff about the SQLAdapter and a DataSet.. is that better in performance? Why is it better? What about LinQ? Thanks a lot for any clarification.
I am using a SQLDatasource to populate a dataview as illustrated below. I run into a problem when I search for a "LastName" that includes an (') Apostrophe ( e.g. O'Reilly) . Searchin for the whole name there is no problem, but when I search for simply O, or O' I get errors. I am not sure ...when to address names with an apostrophe... 1) On insertion to the database (using a "Replace(LastName, "'", "''") 2) or after they have been entered and they are to be searched for. If scenario 1, can anyone provide the best way to do this...If scenario 2, how would that be worked into the SQL Datasource code below.... I have tried several variations with the times SQL Datasource to no avail.... I would appreciate any help ! Thanks ! <asp:SqlDataSource ID="SqlDataSource1" runat="server"ConnectionString="<%$ ConnectionStrings:ClinicTest2ConnectionString1 %>" SelectCommand="SELECT [PatientID], [Accession], [FirstName], [LastName], [Address1], [City], [strddlPatientState], [ZIP], [DOB] FROM [ClinicalPatient] WHERE [LastName] LIKE @LastName ORDER BY [LastName],[FirstName]ASC">
I have a single variable to be utilitized in my SQL Where clause... Select *FROM projectsWhere project_id = @id How do I use this c# variable in the datasource? string TableID; TableID = "192.AB"; I know this is simple, but I figured I'd ask. I don't want to do a work around , like a hidden textbox with the value assigned, and then link the datasource to the tb control, seems extremely hackish.
Hi When I try to configure a SQL datasource and I use a Microsoft SQL Server datasource I get a blank drop down list for server name. My aspnetdb is available in SQL Server 2005 and I can log into it through management studio, and the service is started. I am also using Vista Ultimate. Is there any other configuration I need to do for Visual Studio 2008 to see the SQL Server instance? Thanks Kwis

im using this datasource to extract values from a database.i simply want to extract the values for ratingsum and ratingcount to populate variables so as to be checked within a code loop.how do i do this? in classis asp would be something like <%=rsRecords(RatingSum)%><asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" ProviderName="<%$ ConnectionStrings:MyConnectionString.ProviderName %>" SelectCommand="SELECT SUM(rating) As RatingSum, COUNT(*) As RatingCount FROM tbl_Rating WHERE Itemid=100"> </asp:SqlDataSource>
I have a simple form that accepts a zip code and a city when the submit button is hit this is triggered... Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSearch.Click Dim Zip, City As String Zip = txtZip.Text City = txtCity.Text grdZipCodes.DataSourceID = "ZipSearch" ZipSearch.SelectParameters("ZipCode").DefaultValue = Zip ZipSearch.SelectParameters("City").DefaultValue = City grdZipCodes.DataBind() End Sub This is supposed to populate a gridview with filtered data. Instead I get nothing, even though in query analyzer if I dont provide a city or a state all results are returned. Is there a reason my gridview is not populating.
New to databases so need some help. While trying to set up data source in control panel, I find that there are no drivers for *mdf files. Just *.dbo and *.xls and others. Can someone tell me what to do. I can't get analysis services to let me access my database, which are *mdf files a friend sent me.
I am trying to do incremental extract using Datasource reader. I need to send a variable in where condition to extract the data base on the max date from other table.
To implement this i have created two variables 1)to get the max date from the table. 2)to store the sql query and send the mad date from other variable to extract the data.
i have give this sql variable in data flow expression.but its not working.
I am using SSRS 2005 (Report Designer), and in 1 of the Report, I have a Report Parameter for example say IMask (Dropdown List), which I am populating by values from the following XML file (Imask.xml)
2) If no nodes(<INVALIDMASK>) are present in the XML file, I get no results when the above XML query is fired. So, Is there any way of getting the count of rows returned by XML query. And in case of no rows I want my Report Parameter (IMask) to have €śvalue field€?= NONE and €ślabel field€?= NONE
