Microsoft BI Conference

I'm going to the Microsoft BI Conference in Seattle.  I leave tonight for San Francisco for the weekend, and then I'll head up on Sunday.  I'm looking forward to it.  I'll post some thoughts on what I see and learn as we go (or at least that's the plan).

using ADO.NET dataset in Reporting Services

Here's a good walkthrough for using XML data from an ADO.NET dataset.

WCF and SSRS

In working on a proof of concept for a new project, the architects were hoping to provide the data via a WCF web service to reporting services. It appeared to be relatively straightforward, although, not well documented. As an additional twist, they wanted to implement WS-Security.

I did some experimentation . . .

I found some semi-useful information on MSDN – (345251 for example, which has a decent outline on XML query syntax). I was able to use this to consume information non WCF web services that existed already.

While I was experimenting, the .NET developer was busily creating a WCF web service for consumption. When it was ready, we gave it a try.

No dice. Very frustrating. Second and third tries all yielded the same results. I was unable to connect to the web service.

While I was trying to resolve the problems, I found ONE blog post on the subject. In it, Jesse Ezell described his frustration in trying this very thing.

I think he summed it best when he said:

"1. SQL Reporting Services XML and web services support is slightly better than a piece of crap.

2. Documentation for the XML query provider in SQL Reporting Services blows."

The first step, he explains, is to expose the WCF service using BasicHttpBinding. I got the .NET guy to remove the WS-Security binding, and everything started working. Hope that this saves someone the headache!
