Problem When Grouping By Description

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :Sql Server

Hello, I am encountering a very strange problem with grouping... I have a database that has data for the same field but for different years. For example, the following are all different data fields:

'Standardized Mortality Ratio, 2005'

'Standardized Mortality Ratio, 2006'

'Standardized Mortality Ratio, 2007'

'Standardized Mortality Ratio, 2008'

'Standardized Mortality Ratio, 2005-08'

I am trying to group them using the following expression:

=LEFT(Fields!Description.Value, INSTRREV(Fields!Description.Value, ",")-1)

The first four fields with single years are being grouped together without difficulty, but for some reason the one with '2005-08' is being grouped seperately. The really weird part is that the text being shown for each field is exactly the same for both groups.

Thank you for any help you are able to provide.

Export to CSV w/ grouping problem after 2005 upgrade

Hi,After upgrading to reporting services 2005 from 2000, reports that used to export to CSV correctly don't now. It appears the CSV export suddenly stops at a table with grouping. Any ideas would be appreciated...Thanks.

problem seems to be related to grouping by on columns with the same name in different tables


using OLEDB provider IBMDADB2.1

and the following SQL run from ReportBuilder


sect.name as Team,

tasktype.name as TaskType,










The SQL runs fine in a DB2 query tool but when run through ReportBuilder I get

[DB2/LINUXX8664] SQL0119N  An expression starting with "TASKTYPE" specified in a SELECT clause, HAVING clause, or ORDER BY clause is not specified in the GROUP BY clause or it is in a SELECT clause, HAVING clause, or ORDER BY clause with a column function and no GROUP BY clause is specified.  SQLSTATE=42803


Basically the problem seems to be related to grouping by on columns with the same name in different tables.

Anyone know a work around?

Add Total Problem while grouping and limiting number of rows in a page



I have a report in which first column is CITY and consists of 5 data (5 cities),all other columns are grouped w.r.t CITY, i.e in one city there can be 100s of other column data, last column of report is INCOME. If I right click on [INCOME] field and select ADD TOTAL then it gives citywise total, but I limited only 10 records per page and pagebreak  option is selected at end of the CITY group. When perform the same operation now it gives pagewise sum not the groupwise, please rectify my approach if I am wrong else suggest the solution.

Playing with Linq grouping: GroupByMany?

One of its features is grouping. Many people understand grouping like it is defined in Sql. Linq is implementing grouping quite the same way. Let's discover this syntax and how to make consecutive groups easier.

The requirement of the project is to show a table of data with the riskdetails(just for assumption) which have the corresponing values for every month and people used to compare the values for last months.

ASP.Net Caching problem ??


I'm having a problem with an asp.net 3.0 application using a gridview to display data.  The problem seems to be that despite a brand new .selectCommand being sent to the sqlDataSource, the gridview starts displaying data from *someone else's* query.  For example, user A is logged in and will be working fine until a few page submissions later when the gridview data starts suddenly showing information that belongs to another user. 

This is my first asp.net application, though I've been working with classic asp and ADO for years so I'm used to sending a SQL string and getting back the results from that string.  Apparently there is a complex caching system which is interferring which I do not at all understand so at this point I just want to stop the server from caching any data whatsoever.  Is this possible?

Any and all help will be much appreciated!!

RaiseEvent problem


I have a parent page ProdView.aspx and two static UserControls, UC1 and UC2. Each UC is in an Ajax accordion pane and the accordion inside an updatepanel.

UC1 has a Gridview footer with couple of textboxes and a link button that fires an Add Row insert procedure. I want to Raise an event that will rebind the UC2 after the row insert in UC1.

First I created the sub delegate and event in UC1:

  • Public Delegate Sub MyRefresh(ByVal sender As Object, ByVal e As CommandEventArgs)
  • Public Event Refresh_UC1 As MyRefresh

In the same UC1 the Insert procedure that fires the insert and RaiseEvent:

Sub PricingGrid_Insert(ByVal sender As System.Object, ByVal e As EventArgs)
       Dim myConn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("LocalSqlServer").ConnectionString)
       Dim myCom As SqlCommand = New SqlCommand("AddRow", myConn)
       myCom.CommandText = "AddRow"
       myCom.CommandType = CommandType.StoredProcedure


Gridview Enable Selection Problem



I have a gridview with Enable selection and Enable Paging equals to TRUE.

I also set the PageSize of my gridview to 4 so that I only displays 4 rows per page.

The problem is when I click the pager in the bottom of my gridview, my gridview is disappearing and no records appear.

Here is code behind of my gridview:

If e.Row.RowType = DataControlRowType.DataRow Then
                e.Row.Attributes("style") = "cursor:pointer"

                e.Row.Cells(2).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(3).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(4).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(5).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(6).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))

Problem making Role based Menu in MVC application



 I want to make Rolebase menu in MVC such that if user doesnot have permission for some action then that Action name shouldnot be shown in the Menu.

 I have used the code in the url(http://forums.asp.net/t/1566328.aspx) in my MVC application.My application is a Discussion Forum(in MVC) same functionality as in this forum forums.asp.net

 I have used Controllers for post, thread etc.In each controller there are some actions that are using [Authorize(Roles)] attribute

 but this coding does not count  those Actions in Controllers having Authorize attribute according to the url http://forums.asp.net/t/1566328.aspx 

 In the code, Authorize attribute is applied to Controller class, but my requirement is of Applying Authorize attribute to some actions in controller so that some are available for all users and  some links are available rolewise.Now what is the solution for that?
