Passing OLAP Parameters Within a URL

Hi there!

My report uses an OLAP query with a (multi-valued) parameter, the MDX generated query is something like "...ON ROWS FROM ( SELECT ( STRTOSET(@.Region, CONSTRAINED) ) ON COLUMNS FROM [cube]) ...".

The report works fine using the Report Manager frontend. Now I want to pass this parameter directly within the query string:

https://servername/ReportServer?/PathTo/MyReport&rs:Command=Render&rs:Format=HTML4.0&Region=[foo].[bar 123].&[baz]

But I cannot get Reporting Services to accept the parameter instead of complaining about a missing parameter value. I've already tried quoting the braces, spaces, and the ampersand, putting the dimension in curly braces and/or quotes... No success.

How do I quote this parameter correctly?

I do this befor but so it was as follow

Report server URL(http://Machinename/reportserver/) + Reports Folder (MyReports/)+Reportname (My report) +"&Firstparametername"+Value+"&secondparametername"+Value

it will be like this

http://Machinename/reportserver/(MyReports/My repor&Firstparametername=Value1&secondparametername=Value

Thanks for your reply.

Normal query parameters work fine, I just can't pass OLAP parameters (dimensions like "[foo].[bar 123].&[baz]") this way. ReportServer won't accept them, I think it doesn't like the way I'm trying to quote them...

Thanks and best regards,
Thomas

Hi there!

It was indeed quoting related, I must have confused hex with decimal notation in my earlier attempts.

All you have to do is urlencode the parameter names and values. Here is how to quote correctly:

InputEncoded[%5B]%5D&%26spaces+ or%20

Or you let ASP.Net do the job:

1string encodedParam = HttpContext.Current.Server.UrlEncode(myParam);

So ...&Region=[foo].[bar 123].&[baz]... becomes...&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bbaz%5D...

If you want this parameter to have multiple values, just use it multiple times in your URL: ...&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bbaz%5D&Region=%5Bfoo%5D.%5Bbar+123%5D.%26%5Bheureka%5D...

HTH and best regards,
Thomas

Passing Multi-Valued Parameter to Subreport

I have a multi-valued parameter that I want to pass to a subreport. The values are 11, 12, 13, and 14.

So here's what I've done:

1. For the properties of the clickable field of the first report, I have gone to the Navigation tab and chosen the subreport in the "jump to report" pulldown.

2. Then I clicked on the Parameters button and added a parameter name for the multi-valued parameter I am trying to send. For the Parameter value, I have tried 11,12,13,14. I have also tried =Split(11,12,13,14)

3. On the subreport, I create a report parameter with the same name, data type is string, multi-value is checked, and the available values pulldown is populated by a query.

So I run the first report and click on the link that brings me to the subreport, but all the subreport shows is the results for 11, not 12, 13, and 14.

How can I get the second report to understand that I want it to show all the records related to 11, 12, 13, and 14? If I bypass the first report and simply use the drop-down to choose 11, 12, 13, and 14 in the subreport, it works fine. I just can't seem to figure out how to correctly have the first report tell the subreport that it wants 11, 12, 13, and 14.

Thanks in advance for any advice!

Jarret,

Thank you so much! That post revealed my mistake. I was forgetting to specify the delimiter in the Split statement.

When I pass the following: =Split("11,12,13,14", ",") out of the first report
it works just fine.

Have a great day!

Passing multi-valued parameter to a Sp

Hello,

I am forced to use a Sp in teh first place as my query is too long for the text dataset. I have a parameter Time_Period which ia a multivalued one but it is not allowing me to use this in the SP. using RS 2005.

Any help appereciated.

Thanks

You can use multivalue input params from RS to a stored proc. The input param comes in like a single string like @.Input = 'Val1,Val2,Val3' and then you can split these with a table function which returns 'Val1',Val2','Val3' . Then, use an IN stmt in your where statement in the stored proc ie WHERE Val IN (SELECT Item FROM dbo.SplitParams ('''+ @.Input + ''', '',''))'. See this thread for more info.
