I am creating a kind of feedback website which has a feedback form on it. Each question is answered choosing from a radio button group. the answers to each question are (very good, good, bad, failed). I need to be able to create a table on the webform that will display the number of answers to each questions. for example, if the question is "Rate the use of this software" i need to be able to put in table format say 20 people said "very good", 30 said "good" etc. at the moment i only have one table to display the questions and answers and a date that will be used to select the date's report. so all the information i need is coming from this table. all i need to do is how to say like "SELECT Count* Question where Review date = "user entered date" and answer = "very good" etc.

Well it's finally time to stop ignoring my unit's need for reports. I keep coming to dead ends. I gave up the crystal reports idea, and ssrs seems a little easier. Now the problem is that I'm creating a report locally on my laptop, then will change the connection string, upload it to my server and have it run against an identical database on the server.
I'm using SQL Server Express locally, and when I try to create a dataset (using the wizard), I can see the tables, but when I try to add one, I get an error message "Could not retrieve schema information for table or view". I looked up this error and there isn't much useful info on it. I guess it some bug when trying to use SS Express? Is there a work around for this? Can I create the report programmatically? Should I use a different kind of reporting service?

I have a profile of member to be displayed. I am using a dataset with all the data table adapter to retrieve the information from database.
I have a memContact method which has NRIC and Number as a composition primary key. Thus, automatically, the table adapter has created a method called FindByICNum () for me. However, when I do the search to display the contents, i will only need to search by memberic instead.
Is there anyway to change the table adapter query?

I have a web page with a GridView and a table outside the gridview to display more information of the record when it is selected (like record details). I'm using data of five tables for this particularly window. I use one table of the five to bind the gridview the other tables are for the details, but I use like 1 or 2 fields of those tables. I'm binding the page with web services. I need some advice on which is the better way for doing this to make a faster web page.
In sql server I made a view with the five tables (all the tables relations are working perfectly). In the web service I call the view; and in the web page I call the web service to bind the page. Everything is working. All I want to do is retrieve from the server all the necessary data only once when the page loads and bind the five tables data (like 18 fields total) in the gridview which I only show 12 fields the other 6 fields are hidden, those 6 are for the details which I get with jQuery (that's another topic). Bind everything only once and manage the data on client side. Everything is working perfectly. Here is my doubt.
How are the maximum table joins I can make? To retrieve the data via web and not get a server time out error. Which is a better way to make a faster page? Make 2 views one for the gridview and one for the details and put each view in a web service; or make one view with all the table joins and one web service. Right now all is working but I have to make other pages that use different tables and joins and I don't know if the server gets me the time out error when the page is fully working.
On my website, I'm using webservice to retrieve the data from (SQL Server) database. To improve performance, I like to use jQuery to retrieve the data from the webservice instead of using C#. The data values should be assigned to the drop-down list which I'm using in the aspx. Can anybody tell me how to do this? I'm a newbie to jQuery.
