I'm writing a Data Processing Extension for SSRS 2005 that allows you to use a WSS 3.0 List as a dataset.
This works for one list per dataset. Now I am trying to extend the extension to allow multiple lists in a dataset because I want to join lists on a common field (INNER JOIN). The problem is that I can only return one DataTable to the Report Server with the DataReader. Does anyone know if it is possible to return multiple DataTables (without the join)?
I'm a student, working on this project. I know Visual Basic.net but only started last month with Data.
I have been getting to grips with writing a custom data processing extension for using a supplied dataset. I have got it working OK so far, but I don't see how to make use of relational data. There's plenty of code for walking through the fields, but nothing to walk through the tables. Since this clearly has to be possible can someone tell me where I'm going wrong?
I am using an OLEDB data source connecting to an Access database. Using SQL Server 2005 SP2 Workgroup Edition.
I can build the report fine and view it in Visual Studio. When I deploy the report and try to run it on the Report Manager site I get this error
An error has occurred during report processing. (rsProcessingAborted) An attempt has been made to use a data extension 'OLEDB' that is not registered for this report server. (rsDataExtensionNotFound).
When I go to the Shared Data Source, this message appears beside the Connection type field
The data processing extension used for this report is not available. It has either been uninstalled, or it is not configured correctly. What am I doing wrong??
I need help about this , What i've done so far is a data processing extension that gets its data from a WS , I use it as a datasource for a report , That report will be displayed withing an ASPX page containing a reportviewer control that displays that report , The problem is catching errors that occurs withing the data processing extension .. ,
When i debugged the extension i saw that after throwing an exception the code ends up inside the "cancel()" event inside the IDBcommand implementation...
In all examples for a data processing extension i could find online they always have a comment saying the cancel is not implemented and throw a NewUnsupportedExtension()..
What happens is i get some uninformative , non-userfriendly error from the reporting services , something like "an error occurred during the report processing(rssomehing)"
How should i go about handling those exception that happened inside the data processing extension?
I've tried catching the error inside the event of the reportviewercontrol - reporterror but it seems that event don't fire when those errors are generated..
Any help on how to approach this would be highly welcome
I've created a custom Data Processing Extension and I've implemented the IDBCommandAnalysis interface so that my reports can enter parameters and pass them to my Data Processing Extension.
My question is, how do I extract the value from the Parameters coming from the report? Where do the parameters get passed off from the report? I can query the Parameters collection and my report gets prompted in Preview mode to enter something for the parameter but I can't find the spot where it gets passed for processing.
I am using Custom Data Processing Extension to call a stored procedure. Iam getting following error when creating a dataset in report designer using the extension. I wrote the code in c#.
could not update a list of fields for the query. verify that you can connect to the data source and that your query syntax is correct.(Details-Object reference not set to an instance of an object.)
Here is my code
using System; using System.Collections.Generic; using System.Text; using System.IO; using System.Data;
I am having a question as stated in the subject title, yes, when we want to deploy scorecards to reporting services, as the prerequisite, how can we install and register the scorecard custom data processing extension with the Microsoft reporting services server?
I am looking forward to hearing from you shortly and thank you again.
I'm trying to get data from WSS lists by web services. I think there are two ways:
- using SSIS standard components (Web Service Task) and - creating a custom source adapter.
My problem with the Web Service Task is, that the WSS method GetListItems has some non-standard parameters (see part from wsdl-file below). Thus, after selecting the method in the editor an clicking on "Ok", I get the error message "The selected Web method contains unsupported arguments". I think the problem is the missing type-attribute.
I`ve created a table in a list that is grouped by years. Result is a Report, that consists of several years (List grouped by years, each containing the table with the data of the year).
Now I want to aggregate some numbers of the table on each page (year) of the list.
The sum()-function - doesn't matter which scpoe I use - always aggregates only the values of the actual list (Year), not considering the years before.
I need to do data transfer from three tables in SQL server 2005 to the single Excel sheet as a report. Even If I create a Lists or named range, I couldn't able to transfer the data into the Lists. The idea is, whenever the data is transfered into the Lists, the three Lists (or Range) having data should grow separately.
Currently the data is transfered out of the Lists.
I recently installed the Teradata .NET data provider and I am trying to use named parameters and multi-value parameters in my SQL. I am finding information on this topic hard to come by.
In order to get parameters to work do I need to write my own Teradata data extension from scratch, expand an existing data extension to work with Teradata, or can I simple edit my .config files to point to a generic extension wrapper already existing?
My query should be pretty simple to answer by the gurus. I have SQL Server Express Advance series installed at my system along with VS 2005. I tried the reporting services (remote mode) to display a report in the report viewer on my aspx page. The report simply uses an SQL query to get the result. Everything works fine and dandy!
However if i want to get data from my own data set, i used a webservice and ussed the XML data source option in the report to traverse through the XML. In the preview mode of the RDL everything works fine however when i deploy or rather run it using report viewer on my webpage, it gives an error that 'XML' has not been registered as an extension etc.
I looked in the rsserver config file, it IS configured. The only answer i have is that the EXPRESS version of SQL only supports the regular SQL data sources. I do not understand if that was the case, why does the preview mode work fine??
If i am correct then for the next release the ms developers should disable that or rather give a more meaning full error. I spent an entire day fideling around just to find out that it isnt supported with debates all over the place as to why in the world does it work in the preview mode?
Anyhoo, to get around that issue, i am wondering if the Custom Data Extension would work on the SQL Express or not? I am assuming it wouldnt. Please clearify this. Ideally all i want is to access my own data set in the report, no SQL queries or whatever, CDE seems the way forward but does SQL Express allow it?
Many thanks guyz.

I have written a Data Processing extension for my application and can deploy it on my development machine no problems. My question is: what is the "correct" way of deploying an extension to an end user's machine? Do I have to write a special program to find and modify the Reporting Server config files and copy the extension over. Surely many developers have the same need so there must be a generic solution to this problem, however, I haven't managed to find one.
I first came across this issue in SQL2000 and I thought/hoped it would be rectified with SQL2005 but it appears not to be (unless I'm missing something).
In SQL 2k5 every db object say table , table fields etc have extension properties . I plan to populate these extension properties with meta data related information like field description , string length , case conversion , field alignment , enum options etc .
I wish to know if anybody has done, anything like this . Can this properties be easily avaialble in .Net development , reporting services , BIDS etc . Can there be significant advantages wrt this .
I build a CDE on the base of the FSi-Example. Deploying worked fine
here is the problem: I build a new shared data source, but can't edit the connection string. the button disables itself. why? Therefore I copied the string from an existing datasource. I supplied the auth-data and all seemed to be fine. when i want to build a dataset with this datasource, I get something like this: "no connection to database possible check connection string and test connection. "
But this is not possible because of the disabled edit button.
Can anyone help please? What's wrong?
dev-pc and server are not the same machine.

I am using a Win XP machine with SQL Server 2005 Express Edition with Advanced Services SP2. Just curious, but does express version support CDEs?
i have sql server 2000 db with two data file... primary data file has extension mdf and secondary file has extension ndf (as per microsoft recommendation)..
when i try to backup the db and restore thru the enterprise manager .. in the restore -> options window ... i see both the files has the same extension mdf.. and when the restore completed, the new database still has extension mdf for both the file..
why this behaviour?
* i even try to create a new test db with two files, still its the same behaviour.
I try to add an data extension who take the information to connect to the database in a config file. But It's could not retreive the values corresponding to the key.
I'm using the class ConfigurationManager from the namespace System.Configuration.
ConfigurationManager.AppSettings["QueryModel"]
Without the config file, the extension is working well.... I got the impression that reporting service and Visual Studio BI don't find the config file.
If someone can help me or have some advices. I will be pleased
I am running SQL Express Advanced addition on an XP pro box. The install went cleanly, and I have no problems creating and publishing reports that use a SQL server data source, however when I try and publish a report that uses an oracle data source I get the following error.
An attempt has been made to use a data extension 'ORACLE' that is not registered for this report server.
The report works fine withing the preview pain of Visual Studio, and it publishes fine within SQL 2005 standard edition.
Can someone please tell me how to register the data extension for ORACLE in SQL Express.
Can anyone tell me what the heck this is trying to tell me. I have 3 datasets I'm working with so there are errors for each here:
[rsMissingFieldInDataSet] The data set €˜Revenue_By_Client€™ contains a definition for the Field €˜Branch€™. This field is missing from the returned result set from the data source.
[rsErrorReadingDataSetField] The data set €˜Revenue_By_Client€™ contains a definition for the Field €˜Branch€™. The data extension returned an error during reading the field.
[rsMissingFieldInDataSet] The data set €˜Main_Dataset_AZ€™ contains a definition for the Field €˜PostedAmount_InHouse€™. This field is missing from the returned result set from the data source.
[rsErrorReadingDataSetField] The data set €˜Main_Dataset_AZ€™ contains a definition for the Field €˜PostedAmount_InHouse€™. The data extension returned an error during reading the field.
I am using this custom data extension from BI Studio.
Que1: I want to create report parameters from BI studio and capture them in my Data Extension.
Que2: Every report parameter has so many properties, like hidden, internal, default value etc, how do capture that information in my data extension, the parameters only give me name and value.
Que3: I know I can capture command Text. So My command can be Select * From tablename where fieldname= @myFieldname. Once I get this commandText in my data extension, How do extract parameters of the command?
Que4: If I have any custom attributes in my RDL file, Can I capture them in my Data Extension ?
I have written CDE to retrieve and process data before generating the report. It works very well inside VS.Net. However, when deployed to the report server I get the following error
An error has occurred during report processing. Cannot create a connection to data source 'CallsTaken'. Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I have added appropriate CAS entry in rssrvpolicy.config file as following

I am attempting to deploy a sample report (SQL 2005 Workgroup w/SP2) and I am receiving the subject error message when I attempt to view the report on the web server. We are using SQL Server 2005 Workgroup Edition connecting to an Oracle database.
Is this a limitiation of this version? In report designer, I am able to select Oracle as a connection type. If I try to create a data source at the server, "Microsoft SQL Server" is the only option available. If I look at the ReportServer config file, I see many other data connection types available. Did I miss a step, or is this a Workgroup Edition limitation (it's not documented as a limitation that I am able to find)?
Using SSRS 2008R2 is it possible to change the file extension of a CSV data driven subscription? Â I'm outputting a text file with a .csv extension, but users have access to these files and I don;t want them opened with Excel and then saved back in an incorrect format.Â
These are the options I have from the report "manage" option. Â

Hello everyone. I need help regarding the following:Given the following table:CREATE TABLE T1 (C1 nvarchar(10), C2 money)INSERT INTO T1 VALUES ('A',1)INSERT INTO T1 VALUES ('B',2)INSERT INTO T1 VALUES ('C',3)let's say that i have this table in a local server and i want to uploadit to a remote server and in the remote server upload it to a databasethat contains the same table.the uploading part can be done by another application in the remoteserver, but i want i need is a way to transfer the data at the fastestpossible way.what steps do i need to follow?tia,Rey Guerrero
I'm working on a system right now where I have a database (two,actually, but one is discarded halfway through), but it's createdand used as part of a process (reporting), rather than as theactual production data repository. I may be keeping the databasepermanantly, but it would be completely read-only; once theprocess is complete, the database will not change again. This hasme wanting to do a few things that are rather foreign to my usualexperience, and I don't know how many of them are supported.In several cases, I'm summarizing one table into another by severalfields, and then updating the original table with an ID for thesummary row each source row was summarized into (e.g., I summarizePlaceAndProductSummary into PlaceSummary, and then populatePlaceSummaryID in PlaceAndProductSummary). The update of thesource table is much faster if the summary table has a clusteredindex on the summarized fields, but all later access will be fasterif the clustered index is on the identity column. I've beenincluding an ORDER BY the summarized fields in the original insert,so the identity column is in the same order as the summarized fields,but I don't know of any way to take advantage of that in theindexing declarations.As another approach to the above situation, if I change theclustered index on a table, and the rows happen to be in thesame order by both indexes, will the table still get rebuilt?I will never do a roll-back in the process; if an action fails, Iwant to raise an error and halt (and I haven't lost any data).Is there any way to completely turn off logging?Will I gain anything by marking the database as single-user?Any indexes that I am not using while I populate the tables, I'madding at the end with FillFactor 100, to keep any slack out.Is there a way to remove all the slack from everything else, atthe end of the process? During a backup operation would be fine.Thanks,Bill
We have an XML column in a SQL Server 2005 table. Each row of this table contains one XML document.
I want to shred values from the XML documents and process these within a Data Flow. I want the Data Flow to execute once across a record set comprised of all of the XML documents.
I can shred the XML using a For-Each loop and XML Task. I'm kinda stuck on how I then get the data from variables into a Recordset or similar so that I can process this within single iteration of a Data Flow.
Or - is my approach incorrect? I seem to be building a verbose and clunky solution to this problem. I know I could accomplish the same in a pretty simple SQL statement using .value on the XML column... am I missing something? Is a SQL query just better suited to this problem?
I want to capture and process data inside of a stored procedure by executing another stored procedure. If proc1 calls proc2 and proc2 returns 1 or more rows, consisting of 2 or more columns, what is the best way to do this?
Currently, I know I'm returning 1 row of 3 columns, so I concatenate the data and either return it with an OUTPUT parameter or using the RETURN stmt.
