Case sensitive query? Problems with Integration Services Query

Hi,
i am writing a IntegrationServices2005 job which copies the result of a
view to a table.
I found a very strange problem:
select * from [dbo].[warehouse_aufwandurlaub] -> runs in < 1 second.
select * from [dbo].[warehouse_AufwandUrlaub] -> runs in > 30 Second
s
(timeout).
the name of the view is "warehouse_AufwandUrlaub".
If i run the query in query analyzer, both querys exectute very fast.
What is causing this failure? how can i avoid this?
Thx
Best regards,
Patrick DingerSorry i forgot to mention, that i am using SQL Server 2005 with SP1.
Thx in advance,
Patrick Dinger|||Any activites on the server at this time?
Don't you really need WHERE condition?

Cascading Parameters error

I am new to SQL Reporting services - (3 weeks in fact)
I have a report that uses cascading parameters down 2 levels
I select from a dropdown which populates the second dropdown.
I then select from the second drop down list.
There are three more parameters to be entered in by the user - (these
are not drop down lists)
type of test
start date
end date
This runs fine in the test environment
I deploy
then select from my first dropdown.
It crashes out because start date and end date are not entered
It appears that the page is refreshing with all the parameters even
though they are not entered.
Any help is greatly appreciated.
ThanksTry changing the order of your parameters. Put the start and end date
at the beginning.
Or put in defaults. Start and end date of yesterday and today for
example.|||How are you implementing cascading parameters. I have been needing to do
something like this, but do not see how it would be done.
Thanks

Cascading Parameters based off Analysis Services

Hello,

I was trying to do cascading parameters based off my cube and I wasn't able to do this. Is it possible?

For example, I have a dimension that has Products so I first select the parameter for product type (Dairy, Frozen, Candy) and then I have another dropdown listbox that has the name of each product (Milk, Ice Cream, Lemon Drops). The second dropdown listbox should only contain the products that match what parameter was selected in the first dropdown.

When I couldn't get that to work, I went to the source system containing the Dimension tables and just did nice and easy SQL statements from there. It worked but I, for some reason that I can't explain, think this is not the proper way to do it.

Also, is there a way to have a default on the second parameter based on the first parameter selected? I would assume that default would be [All].

Thank you.

-Gumbatman

Yes it is possible. When you use the query designer, by default each parameter depends on the one before it having a value, even if the parameters are not really related. For this, you want to maintain that link. Then, in your MDX that creates the dataset for parameter #2 you can refer to parameter #1 (it will be called something like @.MyParameterName), i.e. you can use it as part of a STRTOSET or STRTOMEMBER function.|||

Sluggy,

Thank you so much for this answer. I was banging my head against the wall trying to figure out how to do this.

-Gumbatman

|||

Could you please post an example of this? My head also aches a lot

I just need the MDX syntax of the second dataset, the one of the parameter that depends on the first one selected.

Is there any way, from within SSRS to "filter" based on the previous parameter inside the MDX sentence?

Using SQL tables datasources and cascading parameters is quite straightforward, not the same with Olap cubes as datasources.

Thank you

Cascading Parameters

Hi,

I am using SQL Server 2005 reporting services. I am having a problem with Cascading Parameters. In my report there are 4 parameter . (Product Class, Product Type, Product SubType and Activites). when user open the report page he/she will have to select a value for product class depending on the selection Product Type and Sub type will be populated. So far its good, but Activities also depends on the Product Class. My question is can we have 2 parameters depend on same parameter. Here in this case Product Type and Activities both depend on the Product Class. I want only those activies in the dropdown which belongs to the Product Class that is selected.

Can anyone please give an ideas?

Thanks

Ashwini

Hi Ashwini,

I am assuming that you are using datasets or stored procedures to fill the parameters. If that is the case, This link -MIGHT- get you in the right direction.

http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=67984&SiteID=1

It is concerning about which dataset is being executed first, and with this, you might be able to execute certain datasets to get what you need and then based the next dataset on the previously executed dataset.

Hope this helps!

Bernard

Hi Bernard,

Yes I have created 4 datasets with stored procedures to fill these report parameters.

SP1 : SelectProductClassAll -->which brings in all the product class

SP2: RptSelectCascadedProductType --> which has a parameter @.selected_product_class and will bring in all the product types for the given product class.

SP3: RptSelectCascadedProductSubType --> which has a parameter @.selected_product_type and will bring in all the product sub-types for the given product types.

SP4: RptSelectCascadedProductSubType --> which has a parameter @.selected_product_class and will bring in all the Activities for the given product class.

Problem is 2nd and 4th SP expects the same parameter. After adding these datasets if you go to Report -->Report Parameters you will only have 2 parameters (which would act as a drop down filter) @.selected_product_class , @.selected_product_type and I added one for Subtypes these 3 drop downs are fine. But I am not able to get the dropdown for activites since my SP4 expects the same parameter as SP1 and I cant use the same name parameter name twice?

I hope I am clear...

I looked at the link which you send it did not give me enough information so I am still confused...

Thanks

Ashwini

HI Ashwini.

Actually you should be able to use the same parameter name.

Have you tried using only 3 parameters instead of 4 parameters ?

I mean, logically speaking, since two SPs are using ONE parameter, I don't see a reason why you would try and use another Report Parameter. Just make sure that the 2 stored procedures are pointing to one Parameter.

The link I posted tells of how datasets can be executed in order depending on what you need. In this case, you would want to execute SP1, before executing Sp2 and Sp3 right ?

Of course unless, I am getting it all confused myself which is not a good thing.

Bernard

Without reading in detail too much, I'd say yes to you can re-use same parameter (same name) for different parameters

e.g. our reports have performance venue dropdown based on the date range selected (@.start_date to @.end_date)

then performance type, based on the venue AND date range

then say seating zones of the venue, based on type AND venue AND date range

|||

Ok may be I am understanding the concept of report parameter wrong...If I only have 3 parameters it will only show 3 dropdown menu when I actually run the report right? for ex: Product class, type and subtype. I need to have another dropdown menu for Activities as well how would I get this if I dont have a report parameter for it?

As per my understanding SRS will create these dropdown menus for you based on the report parameter. Please correct me if I am wrong...

|||In your case, you only have 3 params, isn't it. The #2 and #4 sp share the same parameter which is your Selected_Product_Class. So when user makes a selection for ProductClass both sp should run based on that Product Class. If you want to pass different values of Selected_Product_Class to these 2 sp, then you need to define 2 separate parameters and fill them both with your #1 sp. But in that case you will have 2 Selected_Product_Class, not sure if that's what you intend to do.|||

Ashwini Ramaiah wrote:

Define another parameter and fill it with your #1 sp, just liek you did earlier. And pass the value of this param to your #4 sp. But this way, user will be able to select 2 different values of your ProductClass. If you want them to be same, then just fill this new param with the value of your already selected product class parameter.

|||

Thanks Everyone!!!

Its working now....I am not sure what was the problem. All I did was delete all my parameter and datasets and re do it. I created a 4th parameter and hooked it up with Activities Data which in turn is looking fo SP4 which expects @.selected_Product_Class parameter. Trust me I did try this like 100 times it didnt work that time when I deleted the whole thing and recreated all the parameters its all good now.

I have 4 dropdowns in my Report when user comes in He/She would only be able to select a value from Product Class rest 3 will be grayed once product class is selected Product type and Activities dropdown's data gets populated and the user can select Product Sub type which is 4th dropdown. This is exactly what I wanted.

Once again thanks to everyone!!!

Capturing Processing Status and Progress Messages

When you use BI Dev Studio or SS Management Studio to process an Analysis Services database or object, there's a nice dialog box that shows very robust status and progress information.

Is there any way to capture this information if you are processing something programmatically? Specifically interested in both the ability to capture and display this information to a user when processing via a custom application. Also interested in whether or not there's a way to capture this information to a log (or table) for display and analysis after the fact (or if the custom application is running in a batch mode via a schedule).

Thanks,
Dave Fackler
I've been looking for the same thing. Were you able to find where this information is stored/logged?

Thanks!
|||One simple way to do this is using the SQL Server Profiler tool which has the option of logging trace information to files or tables as well as the UI. You can also do this programmatically using the AMO using Server.SessionTrace or by adding custom traces to Server.Traces.|||

Using the AMO, you can listen Session Trace. Sample code is following:

this.sessionTrace = server.SessionTrace;

this.sessionTrace.OnEvent += new TraceEventHandler(sessionTrace_TraceEventHandler);

this.sessionTrace.Stopped += new TraceStoppedEventHandler(sessionTrace_Stopped);

if (!this.sessionTrace.IsStarted)

{

this.sessionTrace.Start();

}

|||

You can use AMO (Microsoft.AnalysisServices.dll from "%ProgramFiles%\Microsoft SQL Server\90\SDK\Assemblies") to subscribe to trace events. Sample code below. The code formatting might be lost when posting, but copy paste in VS, and then "Edit -> Advanced -> Format Document" should fix it.

|||Does anyone know if there is anyway of figuring out which events support which columns from the object model? At the moment I have had to resort to hard coding the columns supported by a given event.|||Thanks for all the responses and the sample code!

I would like to capture this information using SSIS. Of course, the script tasks only supports VB as well. Is there an easy way to capture trace information from the cube processing within SSIS?

Thanks again for all the help!
|||

AMO doesn't provide the list of supported columns for a particular trace event. But, there are 2 other places containing the associations:

- the "tracedefinition90.xml" file (search for it in "%ProgramFiles%\Microsoft SQL Server"). You will need to parse it to generate a user-friendlier map. But please note that this file might change in the future (probably not the xml schema, but columns/events might be added/removed/changed).

- SQL Profiler; when you create a new AS2005 trace, in the 'Trace Properties' window, see the 'Events Selection' tab (generated from the trace definition file)

Adrian Dumitrascu

|||

I don't have yet a sample VB.NET code for using AMO traces, but a work-around is to have a separate assembly containing the trace code (written in C# from the sample posted previously) and use this assembly from the VB.NET script task in SSIS.

Adrian Dumitrascu

|||

You could try running the sample code through one of the online C# to VB.NET converters (eg. http://www.developerfusion.co.uk/utilities/convertcsharptovb.aspx). They are not perfect, but they can get you pretty close.

I don't know if the event handling code will work inside an SSIS script task. In this case one option might be to configure the trace to log to a file.

|||

Thanks Adrian, the tracedefinitions90.xml looks like it could be very useful.

The other thing I just found was that by going File -> Export -> Script Trace Definition. I can get an xmla script that will create the server side trace.

This might suit my needs as I can configure the trace using the profiler GUI, script it out and then just get my app to execute the xmla and then connect to the server side trace.

Hi,

I have created an analysis services project using SQL Server 2005, in which I have included a cube, dimension, data source and data view. Now using the Analysis services Browser tab of cube I can see the Pivot table exactly the way I want where I can drag & drop table fields as per my requirements. But I am struggling to display the same cube over the Web. Can any please tell me that how I can publish the contents of Cube i.e. Pivot table on a web application so that end user can use this. I want the same functionality, which I can see in the Browser tab of Cube in AS2005 i.e. user should have freedom to drag & drop the fields exactly like in Excel Pivot table.

Any help would be highly appreciated.

Thanks in advance.

Take a look at the following link on Mosha's website. It contains a set of links to web-based browsers and applications. You can probably use them as a guide to developing your own custom web-based app for doing this (or perhaps use one of the listed applications directly).
