Can I create multiple report tables from one Dataset?


I'm producing a report in Report Builder 3.0 that needs to show events grouped by time of day, and another table with the same data grouped by day of week. Both tables show the same results, just grouped differently. The query that generates the ungrouped data is expensive, so I don't want to run it twice.

I've created queries in Management Studio that get the ungrouped data into a global temp table, and then I can fetch both grouped data sets from there. Unfortunately I can't get this to work in Report Builder. I have one Dataset that runs the main query, saves it into global temp, and then returns the first result set. The second Dataset returns the results from global temp. This keeps failing, the second result set is blank.

Does Reporting services run the queries in the order they are in the report, or are they run concurrently? If they are run concurrently this would explain it. Is there anything I can do to change this so that the second query doesn't run until the first one has completed?

Is there a better way of achieving the results I'm after?

Create and Use a Typed DataSet by Using Visual C# .NET

This article shows you how to create and use a typed DataSet in a small Web application. Typed DataSets, which inherit from the DataSet class, create first-class members of a DataSet's DataTables and DataColumns, yielding the many benefits that come with the use of strong typing.

insert new records in tables from dataset to database


I have 2 tables in SqlServer 2008.

Table1: T1id, SomeData

Table2: T2id, T1id, SomeData

I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns T1id in both tables.

Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.

I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".

I think i'm getting it wrong with ForeignKeyConstraints, maybe UpdateRule is not set to cascade, i just don't know.

I have been trying to work this out for 6 days now and i'm about to break something on half.

Can someone please guide me to right direction, maybe post some sample, anything.... please!

Dynamically Drop and Create tables, overcoming 4000 charachter limit

We have a Navision SQL-server database for 7 companies. Each table starts with the name of the company. Except for the CompanyName-part, the tables names are equal. I made a Foreach loop that dynamically transfers tables/data from the the Navision-database to a staging-database. I also want to Drop and re-Create the tables dynamically. However, if I try to do that via an expression in a SQL Task, SSIS complains about the 4000 character limit. What is a better way to do this? I want to execute SQL-commands and have SSIS replace part of the tablename with the contents of a variable (being the name of one the 7 companies). I have no access to the Management Studio or the DB so I need it to be done within the package. What is the best way to do that?

DataAdaptor/Dataset problems when no row present in database tables

Hi All, I'm trying to use a DataSet to maintain some rows for a table, and when I've finished my changes, send all changes to the database using a SqlDataAdapter.    I find if there are no rows in the table in the database then I am getting a 'Object reference not set to an instance of an object' when I try to access the table in the Dataset. Is there a way to work with a Dataset like this ie. I start off with an empty table and I wish to add rows, to access the structure of the table rows, build rows, then add them and do the update on the SQLDataAdapter. Thanks, Sinead Here is my code: protected SqlDataAdapter memberDA = new SqlDataAdapter(); protected DataSet memberDS { get { if (ViewState["memberDS"] != null) return (DataSet)ViewState["memberDS"]; else return new DataSet(); } set { ViewState["memberDS"] = value; } } protected SqlDataAdapter getDataAdapterForMembers() { SqlConnection conn = new SqlConnection(); conn.ConnectionString = ConfigurationManager.ConnectionStrings["SiteDBConn"].ConnectionString; memberDA = new SqlDataAdapter("usp_GetMembers", conn); memberDA.SelectCommand.CommandType = CommandType.Stored

Create view that amins to tables of another database on the same sql server instance

Hi to everybody, I found a situation ever met before. I develop on Dynamics NAV 5.01 and I have developed a method to be able to see some particular tables of an external database. In substance it deals with a property of tables of Dynamics NAV. When I create a table in NAV, I can create it in 3 different ways: table common to all the companies table  for company or table linked to a view.    This last case is mine, on the same db of NAV I have created a view with some fields, I have created in NAV a table linked with equal fields and types. Until here all normal.    The view, however, aims to another database that doesn't center anything with NAV but that it is on the same intance of SQL server.    The consumer that accesses NAV is a consumer type database SQL Server and has the permitted db_public and db_datareader on both the database. Then he can read the views on the db of nav both on the db of the other database.    When it tries to enter from the console of sql server, with the consumer database, all it works, if I do it by NAV, it show me an error "The server principal "username" is not able to access the database "some_database_name" under the current security context. (Microsoft SQL Server, Error: 916) "    If I add on the database NAV to the consumer, the role db_owner,

How to use .XSD file as DataSet to create SSRS report?



I am  planning to create a SSRS report and lunch it in a ASP.NET web application (not using report server). Since the dataset need to be manipulated before used to generate report (some data fields of tables need to be filled  using data got from other system using COM+ components) , I hope I can use a .XSD file as the DataSet to create SSRS report and bind data source dynamically in code. It is not a problem using Crystal Report, but I have no idea how to do it either in Report Designer or in VS 2005. Please advise





Multiple Tables on One Page, One Dataset



In SSRS 2005, is there a way to have 2 tables on a page, each displaying a row of data from the same dataset?

In other words:

Page 1, Table 1 data = row 1

Page 1, Table 2 data = row 2

---- new page ----

Page 2, Table 1 data = row 3

Page 2, Table 2 data = row 4

and so on?

Create dataset from LINQ query of DataView


Is there a straightforward way to create a dataset after querying a dataview?  The query itself returns DataRowView objects, which I cannot get to work with CopyToDataTable().

The query looks like:
