SSRS Report from View - reporting-services

An SSRS report has been created .The dataset has been defined on bases of a query.The query is
SELECT Organisation,
SUBSTRING(CONVERT(VARCHAR, dt_dt), 1, 11) AS Expr1,
CNT
FROM v_111_status
Every time I refresh the data in the view and run the ssrs report ,I can not see those changes reflected
on the SSRS reports!
When i fire the above query in SSMS , I can see the changes!
Is any of the dataset property has to be checked to get the data?


Did you try opening the dataset properties in SSRS and clicking "Refresh Fields". If you made changes which created new fields etc... you won't see them until you click "Refresh Fields".
If the problem isn't that you adding new columns etc... you should try refreshing the report.
In the preview tab click the refresh button and see if that helps:
If you're still seeing an issue try to delete any files in the report project solution folder that have an extension of .rdl.data, this file holds details that caches/save the data of the last time you ran the report locally. It is not an important file and will do no harm when you delete it.

Automatic update of fields with SSRS

I'm currently working on a Java Project to generate the XML of an SSRS Report, without using Report Builder (this project writes the XML of a report to an .rdl file).
I'm stuck on the Datasets part of my project. I provide a query to my Dataset and when I open my report, my Dataset is created but the fields are not displayed.
And When I execute my report, I have an error that tells me a problem with my DataSet.
This error means "An error occured during local report processing".
The solution I found is to go to "properties of the dataset" and click on "Refresh fields".
"Actualiser les champs" means "Refresh Fields".
The list of fields is displayed and I can run my report without any problem.
So I wanted to know if it was possible to have the fields update automatically without going through the properties of the DataSet and without the action of the user ?
I have already tried to edit the "AutoRefresh" value of the report, without success.
Is there an option to make this happen or some way to run the script behind the button ?
P.S : I need to generate a hundred of Dataset, so my click on "refresh fields" of each Dataset is not viable.
Thank you for any help you can give me.

SSRS-Datasource won't change when reupload report

I got a report with 2 data sources and both are Shared Data source. I am trying to change both of them to Custom Data Source but when I re-upload the report in my Report Manager, it won't work.
Edit: I don't have an error because the report successfully uploads, but the data source doesn't change. If I have a field in the report, the report shows the new field, but the data source stays the same.

This might be because of caching that SSRS does with the datasource for the report on the server. Do the new datasources have the same name as the old ones?
You could create the custom datasources in the DataSources tab in the Manage menu for the report in the report manager.
To do this open up the Report Menu by click on the "..." then selecting Manage
Then click on the Data Sources Tab, then change the data source to Custom Datasource.
Then set up the datasource like you did in the report, you will need to select SQL Server for the Connection, add the connection string and choose the authentication type which in the image below is windows authentication but I am not sure how it is set up on your server. Then click Test Connection. Then Click Save (make sure you click Save before navigating away).
Or you could delete the old report in the report manager and then upload it again. Note that deleting the report will delete any schedules and other customization you have done ie. Name and Description.

Is there an error message? It won't work could be a bunch of things. I'd upload a picture of the error or whatever screen you can't get past. Let me know when you can do that, then it will be easier to troubleshoot. If you can't upload an image than I would:
Check your datasource connections are correct.
Check your datasets are using the correct connection.

This is a setting thats controlled from the deployment properties of the visual studio SSRS project. Right click the project name and select Properties. Then from the Property section of the general page notice "Overwrite Datasets" & "Overwrite Datasources". Change the one that's necessary and re-deploy to see it updated in the report portal.

SSRS report flashes but won't show anything on report server

I have a report to modify on SSRS (just to add a new column for the table that was created using a custom code function). The table was created using natural key and create "case". I added the natural column for the keys and when I previewed it in SSRS, everything looked perfect! However, when I uploaded it to the server, the report can only select partial selections from a drill-down field/widget. If I choose "select all" for the parameters, it flashes then nothing happens (neither an error message nor data is shown).
It was running fine and I was able to select all the selections for the report in Visual Studio and even extract it in Excel. I thought it was a credential problem, so I used my ID and password for the credentials, but it still did not work.
I tried to deploy the original report that was downloaded from the server, but it wasn't working (even without any changes).
Thank you.

SSRS Report Column Name Is not changing

I am working on SSRS Reports 2005. In the reports there are some columns like First Name, Last Name. I am changing there columns name to FirstName, LastName. After doing this while I am showing the preview of the report old field are reflected instead of new field. When i am view the XML of the report, I am able to view my changes in XML. So why i am not be able to view my changes in preview. Is any thing caching issue? how can i solve this issue. Please help me out.

SSRS has serious caching tendencies. In the Preview tab, you should right click your report and hit "Refresh". You may have to do that each time you change the report.

SSRS different results in Data tab and Preview tab

I get the correct results (nov and dec data) when I run a query in the Data tab of a report that I built in SQL Server Reporting Services. When I preview the report I get old data from October. It doesn't make any sense to me. I'm not sure whats going on. Note: the data is in Oracle.
Here's the date filter I'm using
receipt_date + 2 <= SYSDATE
The query works fine in SQL Developer and in the Data tab in the .rdl designer in Visual Studio... just not in the Preview tab when I run the report... that's when I get Oct. data.
Anyone know what's going on here?

SSRS caches data locally for use by the designer. The cached data is only updated if the developer previews the report in VS.NET using a different set of parameters, which in your case never happens because the report has no parameters.
To allow SSRS to refresh the cached data, navigate to the directory which contains your design-time RDL file and delete any files which have the extension ".data".

This is way too late, but maybe this can help someone else in the future.
When developing SQL Reporting Services reports, a really annoying function is that preview data is cached locally when testing reports instead of fetched on every run. Even explicitly refreshing the data doesn't always fix this. The most reliable way to resolve this is to delete the .data file associated with your report RDL file. These data files are stored in the same folder with your report definitions.
While you can delete these files manually, the following 15 second configuration change to BIS makes the process of deleting all data caches as simple as a menu selection.
Let's see how to achieve this.
In Visual Studio -->
Go to Tools - External Tools...
Add a new tool with the following settings:
Now whenever you want to delete your report data cache, just go to Tools - Clear Report Data Cache.

The only thing that works for me (in 2008 R2) is deleting the .data file and rebuilding the report. The refresh button on the preview tab does nothing nor does editing the RSReportDesigner.config file (located in C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\PublicAssemblies). Very frustrating. If I change the query or sp logic I now have to manually delete the .data file in the report project directory in order to see the the most recent rendering of the data.
Hope this was fixed in SSRS 2012 data tools.

The link in Greg's post points to this workaround, added after Greg posted: http://blog.summitcloud.com/2010/05/disable-reporting-services-data-cache-in-development/ That explains which config file controls the data caching, and says that refreshing the preview may actually get you fresh data. (I'm running a long query now, so I don't know yet if that works.)

Try hitting the Refresh button on the Preview tab.
If I understand properly, that is the same issue I had with mine.
I could see the query run successfully in the Report Data window but whenever I ran the Preview of the report, I was getting no results.
I realised after a bit of mucking around, all I needed to do was hit the Refresh button (mini icons on the the Preview tab) to get the Preview refreshed with the new data.

Is there anything different regarding the dataset's parameters? Do report parameters feed the dataset at all? If so what are they?
Is the report a server report? If so what is the time set to on the server?

There are no report parameters.....the exact same sql is run everytime. I'm not sure what you mean when you ask if the report is a server report.

i have one theory that i haven't been able to test. this report is not deployed to Report Manager but is being run from Visual Studio. I don't know if that makes a difference.

Pressing the refresh button in BIDS VS2010 for me isn't working. Nor did deleting the cache file. My issue was that I didn't have a Row Group - so it was only showing one (old) record on the report.
