Need Help - Grouping multiple fields to get top 10 for month then using that data to get previous mo

Posted By:      Posted Date: October 15, 2010    Points: 0   Category :Sql Server


I’m querying a database in BIDS using SQL 2005 to produce a report in SSRS. All the information I need is in one table.

The table has 3 columns. The data within each column can be identical but when the 3 columns are grouped together they make up a unique set.

For example:
Month     Col 1     Col2       Col3
201009   Field A   Field B   Field C
201009   Field A   Field B   Field D

201009   Field A   Field B   Field D

201009   Field A   Field E   Field C
201009   Field B   Field B   Field F

201009   Field B   Field B   Field F
201009   Field B   Field G   Field G
201009   Field C   Field B   Field F

I need to count the number of times these unique sets appear each month and produce a report showing the to

How to link multiple DataSets then put data fields from multiple DataSets into one Data Region?



How to link multiple DataSets (why SSRS call it a DataSet even there is only one bunch of data fields in it) using keys, then put data fields from multiple DataSets into one Data Region? The reason I have to do this is: There will be 6 major DataSets to be used together few times in same report, it is not make sense to build a huge Matrix for all of them together. (in some data region I use data from dataset A and B, some times I use data from dataset A and C, D ...)





Sorting or Grouping by "External Data" columns secondary fields - only possible for certain value ty


I have a BCS connection to an external system that provides various external data types.

I'm now adding an "External Data" column to a SharePoint list, selecting multiple fields of an external data type to be added as list columns. These fields have different data types, in my case string, DataTime and Boolean.

Editing the list view settings, I can only select the external entity as a whole, or it's Boolean fields for either "Sort By" or "Group By". The other fields are not offered for selection.

Is there any restrictions on which secondary fields of an external data type are supported for either sorting or grouping? Or is there something wrong in the definition of some of the external data type fields?

Thanks in advance for any help on this issue...

External Data Fields in a Word Template saved as a content type in a document library with multiple


I have created a Word Template for a Document Library that has an External Data Column in it of Client Name which also adds Client Address1, Client Address2, Client City, Client State, & Client Zip.  Now this works fine for a Document library with that template as the Template.dotx file. 

I want to be able to make a bunch of Templates and have them all as Content Types in one Library.  When I do this I cannot get the External Data Quick Parts to work.

Anyone have any ideas?

Create ID (uniqueid?) from two fields when data is entered


I need to create an ID from two fields when they are entered into the db for the first time.  I thought Uniqueidentifer would do this, but it looks like uniqueidentifier is random and i have no control of the process. 

My user will enter 4 letters into a column called INIT and 4 numbers into a column called NUMB.  What I would like to do is create an id by combining those fields.

How can I do this?

Cutting Edge: Custom Data Control Fields


In ASP. NET 2. 0, the GridView and DetailsView controls are designed to work together. They don't merely provide complementary services, they also share a number of helper classes and components. The output of the GridView control consists of a sequence of rows, each with a fixed number of columns.

Using the single *.rpt file with multiple data sources


I've created a set of CrystalReports (*.rpt files) for an ASP.NET web app on a development server. I call each report using the following code:

protected void BTN_RunReport_Click(object sender, ImageClickEventArgs e)
CrystalReportViewer_ClientLetter.Visible = true;

ConnectionInfo con = new ConnectionInfo();
con.ServerName = Constants.ServerIP;
con.DatabaseName = Constants.DatabaseName;
con.UserID = Constants.UserID;
con.Password = Constants.Password;

CrystalReportViewer_ClientLetter.ReportSource = Server.MapPath(Constants.ClientLetters);
ParameterFields parameter = CrystalReportViewer_ClientLetter.ParameterFieldInfo;
ParameterField batchdate = new ParameterField();
batchdate.Name = "@BatchDate";
ParameterDiscreteValue batchdate_value = new ParameterDiscreteValue();
batchdate_value.Value = Convert.ToDateTime(txtBatchDate.Text);

foreach (TableLogOnInfo tlf in CrystalReportViewer_ClientLetter.LogOnInfo)
tlf.ConnectionInfo = con;

Data flow task with multiple destinations randomly hangs

I have a package whose control flow consisting of a single data flow task with multiple destinations continues to hang at random locations.  The data flow task is fairly simple: - One OLE DB source (one query of selecting about 10 fields from one table) - 9 lookups that serve basically as left joins to capture which data "drops off" (does a row redirect on on lookup errors to an "error flow") - Two destinations: one the captures all the data that doesn't drop off from the lookups, and another to capture the data that does drop off; these write to two tables unrelated to each other, and unrelated to any of the tables I'm reading from I have tried the following: - Changed one or both destinations from OLE DB to flat file -- still randomly hangs - Removed both destinations altogether -- this always suceeds.   - Removed destination A and leave destination B -- this always succeeds - Removed destination B and leave destination A -- this always succeeds I took great care in making sure I get no warnings when the package runs, even resolving the unneeded column warnings, and the duplicate keys on all my lookups, but it still hangs. However, once I give up and stop the package, the following error is thrown (among others that appear to be a byproduct of the root issue): Error: 0xC02020C4 at Data Flow Task, OLE_SRC AP12 [1]: The attempt to

DataGrid ValidationRule or IDataErrorInfo validation code called multiple times for each data change

Following my enquiry regarding a problem in Datagrid validation, for which managing exceptions is apparently a problem, I tested the two other methods: using validation rules, or implementing the IDataErrorInfo interface. I ran into other problems there, more insidious this time. This has been done on Windows7 (32-bit), .NET 4.0.30319. 1) IDataErrorInfo When this interface is implemented, the this[string columnName] property is called four times for each modification: two times before the cell enters edit mode (with the old value in the corresponding property) two times when the new value has to be validated (with the new value) It strikes me as not really efficient, is there something wrong with my code? Here's the C# part: using System; using System.Windows; using System.Collections.ObjectModel; using System.ComponentModel; namespace DataGridTest2 { public partial class MainWindow : Window { ObservableCollection<User> users; public MainWindow() { InitializeComponent(); users = new ObservableCollection<User>() { new User { Name = "Teddy", Age = "2" }, new User { Name = "Avi", Age = "19" } }; datagrid.ItemsSource = users; datagrid.Focus(); } } public class User : INotifyPropertyChanged, IDataErrorInfo { string name; public string Name

Is it possible to use multiple date fields to have an event show more than once on a Sharepoint 2007

Hello, Is it possible to use multiple sets of start and end times to have events display multiple times in a sharepoint calendar? To clarify: - I have the standard fields of "Start Time" and "End Time" in my calendar list. - Events show on the calendar just fine. - Would like to create additional fields called "Start Time 2" and "End Time 2" within the same record and have the event show multiple times on the calendar. - The recurrence functionality of sharepoint will not meet my needs because the pattern I need to use is not in one of the allowed choices.
