I have a report with four different datasets that slice certain record by different days of the week. I can do the individual summing for each dataset by putting a , "datasetname" at in the expression. I also have 4 matrixes in the report that are grouped on certain transactions within each timeslice. My problem is that if I use the dataset name in the fields, the groups get ignored. Do I have to put the dataset name in each group expression? for example, here is my group expression...
I typically use DataAdapters and Datasets from the toolbox when connecting to a SQL database. Since switching to VS 2005, I am not able to find (or add) these items to the tool box for web site development. Any ideas on how I can get them back? Or is there a better alternative to retrieving the data so I can process it? Any help or suggestions would be appreciated.
Can anyone advise me on how to view the contents of a dataset in VS dotnet 2003..
I had filled a dataset from a query...But i don know what happens after filling the qry results.It might be helpful if someone tells me to view the contents of the dataset
I have become a big fan of the datasets in Visual Studio 2005. I usually create the SQL for each method in the table adapter; however, I am wondering if there is any 'built-in' functions in the C files for sql injection prevention? I have read that using stored procedures is a good method for prevention. Should I be using SP rather than SQL within my methods in the data table?
Is there any possibility of combining data from two datasets to a single report item. If there is any thing that we can do, can any one please tell me what to do, so that my problem will be solved.
I have a table which has over 450,000 records in it, I have now split this into 4 so each table has around 100,000 records in it but I'm still having the problem of the data being returned really slowly.
What I need to do to this data is group it by a code and show the total for each code for every month of the year (this is currently based on one column and selecting the data accordingly). I have created views and put some indexes onto my table but the results are still being returned slowly. Does anyone have any suggestions of how I can speed this up?
Hello all, I have a report with a table and a chart. It uses dataset1 as the data source. All works fine. I create a new dataset called dataset2. The queries are exactly the same. The only differences between the 2 datasets is the database server and the fact that one of the columns is a smallint (in dataset2) and an int(in Dataset1) I change the datasetName property of both the table and the chart to use dataset2. When I run the report I get a conversion error stating that there was an overflow of int2 while using dataset1. I have verified the report is not using dataset1 anywhere. If I delete dataset1 and run the report the error goes away. If I add it back, I get the error again. Why is the report looking at dataset1 if it is not referenced at all in the report? Does SQL RS cache the datasets and verify each when it compiles?
If I have a dataset that has ID and CODE, and another dataset that has CODE and DESCRIPTION, is it possible to relate these two datasets to one another so I put the ID and Code in columns 1 and 2 and then put the related DESCRIPTION in column 3 on the report table layout? In other words, can you "JOIN" two datasets, or must all that be done in the query and create a unified dataset for the report contents?
Each column right now is a subreport so I can use the object as a parameter to the subreports dataset. Each column needs to have the object as a parameter.
Is there a way I can pass a field from the first dataset as a parameter for the next dataset without using subreports?
I have got two datasets. Some 'normal' rows with state values and an addtional dataset with the translation from state value to plain text (value / text pair).
A table object is attached to the first dataset, but I would like to show the plain text from the second dataset in a group header. So I'd like to do some kind of 'look up in another dataset'.
I wasn't able to find a function that could help me solve this problem. Does anyone has any ideas on this?
i have a report in which i use two datasets the problem is that when i was using only one, there wasn't any scope argument you know, to tell in which dataset i am , because there was only one and all fields and cells in my table returned me the correct values
but as soon as i add the second data set and i drag and drop the datasets fields in my table
Can we use 2 datasets in one report (tabular or chart, either one)?
my report get its data-fed from OLAP database (Cubes) and Oracle tables.
Let say the cube contains the actual sale (all aggregated and query using MDX) and the Oracle table contains the budget value for specific period.
And I am trying to construct a tabular like this:
date item type Revenue Budget Actual (Sale - Budget) Jan calls regular 2000 1800 200 Jan calls super 3000 2500 500 Feb calls new 1000 900 100 Mar calls super 4500 4000 500 ..... and so on
The data for date, item, type and Revenue are available in the OLAP (cubes) and the Budget value is available in Oracle table and we can't afford to transfer the Budget value to the cube.
Is this possible in SSRS? Please let me know if more information needed.
I'm creating a report with SSRS (2005). In that report I have a table, and in that table I need to put fields from two different datasets. But I don't know how to link those both datasets (because if I don't I get a cartezien product)...
is this possible? i need to make a report that accesses two different tables, one for user activity and the other for the number of reports that user has done. the report information is in a different database however so i have to use different datasets. is there a way to use both databases in the same table? all i need is the one field from the reporting one and they can be linked by the user id...
1. A mulitvalued parameter State with WA, SA, QLD, TAS etc
2. A single value parameter of Top n - 10, 20, 40
The user will select the state and the top number to get the top n sellers off that state or a combination off states.
I have a dataset with the following cutdown version off SQL
Declare @TopNo Int
Set @TopNo = @Param_TopNo
Set Rowcount @TopNo
SELECT CreateDate,SaleDate,sales.Consultant, State, Sum(Value) As Winbacks
FROM dbo.tbl_kpi_sales
GROUP BY CreateDate, Consultant, State, SaleDate, Winbacks
ORDER BY Winbacks Desc;
Set RowCount 0
When I execute it and select 'Select all' from the mulitvalued state parameter with a Top N value off 100 the query returns all the top 100, which is correct, however when i select just a single state ie WA it only returns me the records which were in the TOP 100 off all states when it should be filtering it by only the state I choose and returning the 100 records...For some reason it when a single state is selected or a combination off states the dataset is already narrowed down and doesnt reexecute the query for just that state...Can someone suggest how to overcome this, maybe a table filter ?
I am relatively new to MS Reporting and I can€™t figure out how to do something that seems rather simple.
I need to somehow combine two different SQL statements into one dataset. The two different SQL statements are the same, except for the Select list and the Where.
Example,
1st Dataset:
SELECT dbo.claimtable.grpnum_plancode, dbo.plancodetable.plandescription, SUM(dbo.claimtable.charges) AS Charges, SUM(dbo.claimtable.benefitpaid) AS BenefitPaid FROM dbo.claimtable INNER JOIN dbo.plancodetable ON bo.claimtable.grpnum_plancode = dbo.plancodetable.grpnum_plancode WHERE (dbo.plancodetable.plantype = 'Med') AND (dbo.claimtable.paiddate BETWEEN @BeginDate AND @EndDate) AND (dbo.claimtable.paidflag = 'Y') AND (dbo.claimtable.grpnum IN (@GroupNumber)) GROUP BY dbo.claimtable.grpnum_plancode, dbo.plancodetable.plandescription
2nd Dataset:
SELECT dbo.claimtable.grpnum_plancode, dbo.plancodetable.plandescription, COUNT(distinct dbo.claimtable.claimid) AS ClaimCount FROM dbo.claimtable INNER JOIN dbo.plancodetable ON dbo.claimtable.grpnum_plancode = dbo.plancodetable.grpnum_plancode WHERE (dbo.plancodetable.plantype = 'Med') AND (dbo.claimtable.paiddate BETWEEN @BeginDate AND @EndDate) AND (dbo.claimtable.paidflag = 'Y') AND (dbo.claimtable.backoutflag = 'N') AND (dbo.claimtable.grpnum IN (@GroupNumber)) GROUP BY dbo.claimtable.grpnum_plancode, dbo.plancodetable.plandescription
I tried just referring to the different dataset within the report table, but it only provides it at the aggregate level and I need the claimcount at each individual claimtable.grpnum_plancode level.
I tried a union statement, but get a variety of errors.
Hi, I am pretty new to harcore ASP.NET and .NET in general but I know the basics of the language and stuff like that. Basically I used to be a hardcore object pascal Delphi developer doing Windows Applications but have now moved to .NET world. The reason I posted this question here is I couldn't find any other specific place to ask so here it goes. To get me started with good programming source and practices I downloaded the ASP.NET TimeTracker Starter Kit and after some modificaion in connection string (using SQL 2005 Developer edition not the Express one) I have managed to make it work. Things done in there are pretty interesting way by using a delegate to retrieve data and present it using databound controls. As much simple as it sounds I am more of a fan of not using too many databound controls except in dropdown box, list box and stuff like that. So basically I need to develop DataAccessLayer (DAL) in such a way that it's useful for both Windows and Web application. So with my research I found that I should be using DataSets in the DAL because they are serializable and thatz what Web Applications & Services love over using SqlDataReader. Other advantage of using DataSet is to use ForEach syntex over While Loop in SqlDataReaders. So below is some code I extracted from the TimeTracker Starter Kit to get me started. I also noticed that the return result is a list array of certain object, in this case Category. So does it mean that it can be used in frontend using ForEach syntex? How can I convert the code below to use DataSets over SqlDataReader? Private Delegate Sub TGenerateListFromReader(Of T)(ByVal returnData As SqlDataReader, ByRef tempList As List(Of T))
Public Overrides Function GetAllCategories() As List(Of Category) Dim sqlCmd As SqlCommand = New SqlCommand() SetCommandType(sqlCmd, CommandType.StoredProcedure, SP_CATEGORY_GETALLCATEGORIES)
Dim categoryList As New List(Of Category)() TExecuteReaderCmd(Of Category)(sqlCmd, AddressOf TGenerateCategoryListFromReader(Of Category), categoryList)
Return categoryList End Function
Public Overrides Function GetCategoryByCategoryId(ByVal Id As Integer) As Category If Id <= DefaultValues.GetCategoryIdMinValue() Then Throw New ArgumentOutOfRangeException("Id") End If
Dim sqlCmd As SqlCommand = New SqlCommand() AddParamToSQLCmd(sqlCmd, "@CategoryId", SqlDbType.Int, 0, ParameterDirection.Input, Id) SetCommandType(sqlCmd, CommandType.StoredProcedure, SP_CATEGORY_GETCATEGORYBYID)
Dim categoryList As New List(Of Category)() TExecuteReaderCmd(Of Category)(sqlCmd, AddressOf TGenerateCategoryListFromReader(Of Category), categoryList)
If categoryList.Count > 0 Then Return categoryList(0) Else Return Nothing End If End Function
Private Sub TGenerateCategoryListFromReader(Of T)(ByVal returnData As SqlDataReader, ByRef categoryList As List(Of Category)) Do While returnData.Read()
Dim actualDuration As Decimal = 0 If Not returnData("CategoryActualDuration") Is DBNull.Value Then actualDuration = Convert.ToDecimal(returnData("CategoryActualDuration")) End If
Dim category As Category = New Category(CStr(returnData("CategoryAbbreviation")), actualDuration, _ CInt(returnData("CategoryId")), CDec(returnData("CategoryEstimateDuration")), CStr(returnData("CategoryName")), _ CInt(returnData("ProjectId"))) categoryList.Add(category) Loop End Sub Hope this makes sense. Sorry if I have posted this in a wrong section..! Cheers,Nirav
I was watching the "To Do List" AJAX video created by Joe Stagner and while watching the video I noticed (in designer) Joe use a Dataset to populate a Gridview and this got me thinking. I have a few gridviews in my app at work that just use SqlDataSources, and they seem to work fine, but is it better to use Datasets ?
i want to make business portal intellegence with sql2000 as my final project but i don't have datasets. i need iventory datasets like northwind or foodmart or middlewest. somebody help me please!!
Not a question, just a post about something I ran into today that surprised me a little.
I have a huge dataset - about 700m rows, one column of which is a tinyint. I needed to take an average of that column, so I did this:
select avg(mytinyint) from mytable
which returned:
Msg 8115, Level 16, State 2, Line 6 Arithmetic overflow error converting expression to data type int.
It turns out, if the sum() over the column is bigger than MAX_INT = 2147483647, then avg() will throw this error. This surprised me a little - I guess I was assuming sql server would use bigint internally when computing integer avg, but it uses int.
so you have to do this:
select avg(cast(mytinyint as bigint)) from mytable
what's annoying to me is, it's impossible that an average of type T could be larger or smaller than the max/min allowed value of a type T. This means sql server devs could have internally always used bigint for sum and count, and then returned cast(sum/count as T) from avg() without possibility of overflow (unless sum or count was bigger than the max bigint! you are on your own if that happens i guess!).
Because of this, you have to cast your column to a bigint to make it work if your dataset is large enough, even if the column is only 1 measly byte! kind of a waste of space if you ask me. :)
here's a little example of what I'm talking about, that doesn't require you to import a 700m row dataset :)
declare @t table (id int) insert into @t select 1 union all select 2147483647 select avg(cast(id as bigint)) from @t -- works select avg(id) from @t -- fails
I need to display the datas in a table format. I have placed a table and now i need to use two different datasets for a single table. Those two different datasets are generated based on two different stored procedures. Those stored procedures retrieve data from two different sql tables. Can any one explain me how to use two different datasets for a single table. As far i have tried i was able to fetch only the first record of the other dataset. But i need to fetch all the records of both the dataset. Thanks in advance for any help.
I am considering using SQL Compact in a new project, but during my testing I run into the weirdest errors.
I don't want to use the specialized SqlCeConnection, but rather OleDbConnection so the application supports any database (theoretically).
I cannot get it to work with datasets though. In my small testapp, I can create tables, insert data and get data with raw sql sentences and OleDbCommands. But when I try to use a Dataset with DataAdapters, then I receive weird errors like:
When I run DataAdapter.Update:
System.Data.OleDb.OleDbException was caught Message="The given type name was unrecognized. [,,,,,]" Source="Microsoft SQL Server 2005 Everywhere Edition OLE DB Provider" ErrorCode=-2147217872
When I try to Configure a DataTable in the datasert-designer:
"Multi-step OleDb operation generated errors. Check each OLE DB status value, if available. No work was done."
Everything works perfectly with Access and SQL Server with the same dataset.
I have multiple different data regions on one report body. I need to be able to arrange the a few of the data regions so that they are grouped together and print together on same page. I've tried using a list around the data regions that I want to group together, but the list data region needs to have a data set specified and it only allows one to be specified. Has anyone tackled this before?
I'm running a report that uses multiple datasets. One of which is basically a script written in SQL. I would like this dataset, let's call it code, to execute before the other ones. How can I ensure that this happens?
I am needing to take data from one data set that consists of a list of parts and their stock information. Then I am needing to show any transactions that the individual parts may have had during the time that user defined through the filters.
This requires me to have two data sets since I can't do a join between the stocking information and the transactions due to the fact that it is very possible that every part won't have a transaction for each month of each year. Doing a left join still filters down the data too much so thus the need for two data sets.
I have these parameters:
Vendor, Year, Month, Type of request
Vendor and Type of Request is handled through StockInfoDataset. I then need to update the table showing 0 or transaction amount from TransactionDataset filtered by the ItemNumber and WarehouseCode that is in StockInfoDataset. Since it seems List and Table only allow one dataset in them, I am at a loss as to how I would go about doing this.
Explaining this is quite difficult in a forum post, but hopefully someone would be able to shine some light on possibly avenues to follow here....thank you in advance.
I have three datasets that are currently displaying data in three side-by-side-by-side tables. This gives the appearance of one large table were all rows match up nicely. Now, I need to somehow calculate the sum of those rows values across and display that value as a calculated sum at the end of each row. How can I access the values of each column from those three different tables in order to be able to add them together for each detail row. Or is this just a dream? Thanks in advance....Using SQL Server 2005. The backend queries that create those datasets are MDX and trying to manipulate those to get one dataset back will be a pain. That's why, I am hoping that there is a front end solution to this.
