Question on installing SQL Server 2008 reporting services.
I have Visual Studio 2008 express edition installed, with the corresponding SQL Server 2008 express edition installed. Is it practical to use SQL Server 2008 Reporting Services with the express edition, or is it just to restrictive with the express edition to be practical? Keep in mind I just need to use it with my local database connection. What type of restrictions will there be, i.e. what can I and what can't I do with express edition? What would be the more ideal setup and what would the costs generally look like?

I have a problem with SELECT COUNT query in ASP.net. I want to create CMS with articles which have categories (which have the option to be deleted). The problem is that I want to get the number of articles within the specified category so if there aren't any articles with the specified category I can proceed with the category deletion.I have the following code:
[Code]....
After I click the button "Obriši" (Delete) I receive the following error: "Must declare the scalar variable "@KategorijaID"." I understand that the problem is with parameter, but I don't know how to correct it to use it for both the "command" and "brisanje" SQLCommands.

I'm building a music voting application, similar to stack overflow almost.I have 3 tables, Charts, ChartItems, Votes.I'm trying to bring back a list of chartitems, which link to a single chart, with the number of votes for each chart item counted.This is what I am trying currently
var firstList = from chartItem in db.ChartItems
join vote in db.Votes on chartItem.ixChartId equals vote.ixChartId into j1
where chartItem.ixChartId == id[code]...
The problem is once I have performed the grouping, I can't get any of the other properties I need from the join to populate the model. For example each ChartItem should have a title, id etc...I have created a ViewModel to hold all the properties that I need, called ChartItemWithVotes(includes all entity values + int totalVotes)In the end I am looking for this
Chart Name
Votes Name
20 - ChartItemname
15 - ChartItemname
12 - ChartITemName

When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

I have a db table MemberOccasion with two columns: memberID and occasionID where I keep members votes for occasions. A member can vote for several occasions. Every time a vote is inserted I need to check how many members have voted (and compare against the number of registered member in another table, but I do the comparison outside of this query). My question is this: Is it possible to do adjust the query below to accomplish this?
This is how I count all memberID in MemberOccasion:
[Code]....
with the result that the data in the table below would be counted as 8. Instead I need to count each memberID once. The result I want is that five members have voted.
memberID occasionID
1 28
1 30
