How To Join 2 Datasets Without Sorting

May 12, 2006

Hi,

In one of my packages, I have join data from 2 data sets. The problem is 'Join' requires both dataset to be sorted and I can't sort one dataset without 'sort' transformation. The real problem is since I have to sort 65million records, the sort operation sucks always. The other option is using 'Lookup', but since I have to do 'Range Lookup', it is taking hours and hours to process less # of records.

My question is, is there any other way, I can do join of 2 datasets without sorting?

Join Two Datasets From A Similar Column

Apr 23, 2008

Hi, I was wondering wich is teh easiest way to solve this:


I have one data set that comes from a sql query with many columns.

I have another data set that comes from a txt file that I am reading.

Both data set have one column in common (for example ID).

In the sql data set, I have many rows and I want to keep only the ones that have the same ID from the data set of my txt file. It looks like a inner join if we talk in sql terms.

So, which is the easiest way to solve this?
Thanks!

Reporting Services :: Overall Sum For Each User When Using Union All To Join Two Datasets

Aug 5, 2015

Struggling to come up with an overall sum for each individual user when using the below code

SELECT
Practice.ibvStaffCategorisation.StaffId
,Practice.ibvStaffTotalsCL2Y.Period
,SUM(Practice.ibvStaffTotalsCL2Y.ChargeableMinutes) AS Sum_ChargeableMinutes
,SUM(Practice.ibvStaffTotalsCL2Y.NonChargeableMinutes) AS Sum_NonChargeableMinutes

[Code] ....

As I am using union all it shows two values for each user, the problem is I am getting the data via lookup like below

=Lookup(Fields!StaffId.Value, Fields!StaffId.Value, Fields!Sum_ChargeableAmount.Value, "ABSTimeRollingY")

I don't think I can use a Sum within a lookup so at the moment it is only bringing through the first value for each user but I would like it to bring through both.

Is there a way to do this within the dataset or via the query in the table?

Dynamic Column Sorting After Merge Join

Feb 25, 2008



Hello,
I have data coming in from two sources, one being SQL and the other being Oracle. The end result needs to be a CSV file with the columns in a specific order. I have a Data Flow task setup that takes both sources and does a Merge Join on them. I can add a Sort Transformation and manually set the sorting of all 156 columns that end up going to a CSV file destination. However, I have a table setup that holds the names of the 156 columns and the order that the CSV file expects them to be in. I would much rather do this step dynamically as the column names and order may change in the future. Anyone who has used the Sort Transformation for a large number of columns knows how tedious it can be and how adding a column in the middle will cause you to change the sort # for each of the columns that come after it.

So I added a Script Component between the Merge Join and the Flat File Destination hoping that I could alter the order of the columns there. However I added the following code and found that the SortKeyPosition is ReadOnly.


Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)


Dim column As IDTSInputColumn90

For Each column In Me.ComponentMetaData.InputCollection(0).InputColumnCollection



column.SortKeyPosition = 1

Next

End Sub

I was hoping to add some code to get the sort index from my table for each of the columns and set it to the SortKeyPosition. Has anyone out there done this before or seen an example that might point me in the right direction? I've searched for 2 days without coming up with much.

Thanks!

Sorting And Grouping Question By Allowing Users To Select The Sorting Field

Feb 11, 2007

I have a report where I am giving the users a parameter so that they can select which field they would like to sort on.The report is also grouping by that field. I have a gruping section, where i have added code to group on the field I want based on this parameter, however I also would like to changing the sorting order but I checked around and I did not find any info.

So here is my example. I am showing sales order info.The user can sort and group by SalesPerson or Customer. Right now, I have code on my dataset to sort by SalesPerson Code and Order No.So far the grouping workds, however the sorting does not.



Any suggestions would help.


Thanks

Reporting Services :: Horizontal Axis Show Last Value In First And Last Space When Sorting A-z But Shows Correctly When Sorting Z-a

Jul 10, 2015

SSRS 2012 - VS2010...The report compares two years with a sort order on a value that has been engineered based on text switched to int.  When sorting A-Z this is the result in the horizontal axis is: 5th, K, 1st, 2nd, 3rd, 4th, 5th..When sorting Z-A the result in the horizontal axis is:5th, 4th, 3rd, 2nd, 1st, PreK..Z-A is correct but A-Z sorting shows 5th as the start and end.  The magnitude of the PreK location is correct but the label is wrong on the A-Z sort order.  The sorting is implemented using the Category Group sorting option.

Datasets And SQL Injection

Oct 25, 2007

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?

Large Datasets

Mar 27, 2008

Hi,

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?

Thanks

Datasets And Iff Statements

Sep 6, 2007



Hello experts,

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...





Code Snippet
=iif(Left(Fields!TestName.Value,4)="VTAM","VTAM Logon",
iif(Left(Fields!TestName.Value,4)="CICS","VTAM Logon",
iif(Left(Fields!TestName.Value,4)="Shaw","SHAW Main Menu",
iif(Left(Fields!TestName.Value,7)="Inquiry","Inquiry Menu",
iif(Left(Fields!TestName.Value,6)="Search","Search Menu",
iif(Left(Fields!TestName.Value,6)="SEAX A","SEAX Auxiliary Search Menu",
iif(Left(Fields!TestName.Value,8)="SEAX - B","SEAX",
iif(Left(Fields!TestName.Value,4)="STLN","STLN","Other Value"))))))))






Not sure where I put the dataset name in this.

Thanks,
C

Cached Datasets?

Aug 8, 2007

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?

regards,
Bill

Relationship Between Two Datasets

Apr 29, 2008

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?

Multiple Datasets

May 31, 2007

I have a report that I have created with multiple subreports and datasets. There should be a better solution so I am asking the question here.



The report should display like this:







Object
Object Title
Budget
Curr-Spent
Ytd-Spent
Ytd-Encum
Post-Ytd
Balance
% Remaining

4100
EMPLOYEES
$380.00
$250.93
$343.67
$0.00
$0.00
$61.33
15.94%

4102
EMPLOYEES - TEMPORARY
$149.00
$110.75
$139.70
$0.00
$0.00
$47.30
30.16%

4201
EMPLOYEE BENEFITS
$138.00
$73.16
$12.60
$0.00
$0.00
$32.40
25.28%



Each column represents another dataset.

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?

Joining Two Datasets?

Mar 8, 2007

Hi All,

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?



Kind regards.

Using Two Datasets In A Report

Feb 25, 2008

hello everyone!

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

instead of having for instance



Code Snippet

=Fields!Consultant.Value






or




Code Snippet=(Fields!Consultant.Value, "dataset1")





it automtically applies the function "first"




Code Snippet=First(Fields!Consultant.Value, "dataset1")





and i don't understand why

please can you give me precious help on this

because it returns me the name of the first consultant only and if i deleter the function first in the expression, the report doens't work anymore

2 Datasets In One Report?

Nov 29, 2007

Dear Experts,

I have a problem regarding my report.

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.

Thanks very much

Filtering Datasets

Jun 18, 2007

I have the following report



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 ?

Combining Two Different Datasets Into One

Mar 26, 2008


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.

Any help would be greatly appreciated.

[Almost Resolved] SqlDataReader Vs. DataSets

Feb 1, 2008

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

Beware Of Avg() For Large Datasets

Oct 31, 2006

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

Hi,

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.
