Reporting Services :: Aggregate Function On Large Value Type
Apr 20, 2015
We are constrained to use a model that stores records in a main table and various attributes of the record in a second table. Something like this: main record table CAR, attribute table CAR_DETAILS with CAR_DETAILS have key value pairs like "color" "blue" and "doors" "4".
For reports we need to flatten the one to many nature of this to get CAR and color and doors by using an aggregate function like:
car_id, max(car_detail.value) filtered on car_detail.key = "color", max(car_detail.value) filtered on car_detail.key = "doors".
This works on other tables but the car_detail table (shall we say) appears to store its values as blobs. In any case when we attempt to aggregate we get "The query uses an aggregate function on a large value type expression. Large value type expressions can not be aggregated."
Since we can't change the model, we would need to use another function to change this to a smaller string (or date, these are actually mostly date), but none of the very limited set of functions available seems to work to make this aggregation possible (and there is no "first" or anything else similar).
The list of functions available in Report Model Queries can be found at [URL] .....
I have the problem of aggregating semi-additive measures correct in higher levels in a matrix control of reporting services. I use the "Microsoft SQL Server Analysis Services" data provider. I have a calculated measure saved in the AS2005 cube which looks like:
In the matrix, I have a 4 level Product Dimension on the rows (4 groups matrix1_level1 ..... matrix1_level4) and the visibility of the groups is toggled by each upper level, so I can drill in the product dimension. I place this measure in the data part of the matrix with (sum(Fields!Net_Sales__kg_.Value)). On the leave level all values ar correct. But on each other level, I see the sum of the sublevels.
After a lot of pain researching, I found that I have to use the "aggregate" function instead of the "sum" function, because aggregate uses the aggregating which comes from the data provider and the "Microsoft SQL Server Analysis Services" data provider is able to do that. Thats all of documentation I found. I have played around with this function, but always when I use it, I get no values on all levels. I tried the "scope" parameter of the aggregat function, nothing changed.
I tried aggreagate(Fields!Net_Sales__kg_.Value, "matrix1_level1"), aggreagate(Fields!Net_Sales__kg_.Value, "SalesCube") (SalesCub is the name of my Dataset in Reporting Services I use), aggreagate(Fields!Net_Sales__kg_.Value, "matrix1") and last but not least aggregate(Fields!Net_Sales__kg_.Value), all is the same, no values.
It seems to me, that the aggragate function returns "Nothing", because than, according to the Online Help, no values will be shown. But according to some blogs and forum entries, the "Microsoft SQL Server Analysis Services (AdomdClient)" Data provider should deal with aggregate. Have I do some special entries in the "Advanced..." Settings of the data provider??
Can someone tell me, what I'm doing wrong, and did someone know a good documentation (with examples) for the aggregate function on the internet. The Help-file doc is very, very poor!!!
I am trying to create a column chart that calculates the percentage of computers in our IT environment that are Actively communicating to our SCCM Server.
I have two datasets:
1. Total_Count_Of_AD_PC DataSet.
2. PC_With_Active_SCCM_Clients dataset.
Basically i wan to calculate the percentage for each Region (i.e. AP for Asia Pacific, EMEA, Americas).
Below is the Total_Count_Of_AD_PC Dataset screenshot.
Below is the PC_With_Active_SCCM_Clients dataset.
Below is the expression that i used that is causing the error.
The Y expression for the chart ‘Chart2’ has a scope parameter that is not valid for an aggregate function. The scope parameter must be set to a string constant that is equal to either the name of a containing group, the name of a containing data region, or the name of a dataset.
Can somebody on the SSRS product team double check me that I've written that up right? That seems like a pretty important change and I can't see it mentioned in BOL anywhere.
I am using SSRS 2014. I'm using a matrix instead of a tablix because it allows me to have dynamic columns. In the example I'm showing, two of the columns use the sum function to get the total counts per practice. The third column contains percentages so I averaged for the total but the value is inaccurate compared to the value I would get if the divided the the two totals that are sums of the counts. Is there a way for me to specify that I want to divide the total counts numerator divided by the total counts denominator?
Here's an example report output with the percentage column averaged (inaccurate):
PCP numerator denominator percentage John Smith 66 104 63.46 Tom Jones 4 36 11.11 . . . Jane Doe 1 1 100 Total 708 1005 72.3
So the 72.3 value is from Avg(metricvalue)
I would like to do this instead: % total = 708/1005, which equals 70.5 - a significant difference.
The metricvalue column is what is the value for every number above (Because it's a matrix).
I'm trying to sum a column in a report. in Most columns I can just wrap the row level expression with "Sum()" and it works. However, I have run into a few that give the following error. The Value expression for the text box ‘Textbox241’ specifies a scope that is not valid for a nested aggregate. The scope must be the same name of the scope specified by the outer aggregate or the name of a group or data region that is contained in the scope specified by the outer aggregate.Here is my row level expression that works.
The sample data above shows 1 customer with multiple episodes (different attend dates – not important here), during the course of these attendances they moved home and moved GP practice.
Is there a simple way in Access to show a summary of this eh PTO1395164 = 2 postcodes, 2 GP’s
THe ultimate aim would be to identify where a customer has changed postcode or GP within a selected timeframe and disregard the rest.
I have upgraded SQL 2005 express to the Express Advanced edition so I could utilize the reporting Services feature. After installing I have the ReportServer db and the 2 IIS virtual directories as expected. As well the Reporting Services configuration menu item is available. However, when I go thru Management studio Express to connect I only display Database Engine in the Server Type dropdown, which is greyed out. I have selected the other SQL Servers under Server Name and none allow for the selection of Reporting Services in the Server Type dropdown. Any suggestions?
I am trying to create a report in report in reporting services.
The requirement is to display the data in a chart. A surface chart to be exact.
It appears that reporting services has most of the Excel type charts available to display the data but I do not see the Surface Chart type. Is this type available in SQL Server 2005 reporting services? If not, is there a 3rd party software available that integrates into BIDS?
I have the problem. I have many Cognos Reports to be converted in Reporting Services. Out of which there are several Ranking Reports. Cognos has inbuilt Rank Function while SSRS does not have. I dont want to do grouping on Database level, rather trying to find a solution in RS. But unfortunately I couldnt find any solution. I sorted the group according to requirement, now only thing left is showing the rank number and limiting top 60 rows only. I tried filters to show TopN, but always gives and error and also tried custom code to show the row number for that group but didn't work.
Anyone has any idea how to overcome this limitation of Reporting Services. One more interesting is when I try to create a field in dataset having IIF and / within.. RS terminates, all unsaved work gone. Sometimes I think Microsoft cannot have a product which is 100% perfact and working.
I am using Sql REporting Services 2005 for viewing reports in my web application. I have to change the chart types at run time basesd on the option. User can select any chart eg. bar chart, pie chart, column chart etc. On selection screen should populate the chart type. I am not able to change chart type at runtime. Help please.
System.Web.Services.Protocols.SoapException: The TypeName field has a value that is not valid. ---> Microsoft.ReportingServices.Diagnostics.Utilities.InvalidElementException: The TypeName field has a value that is not valid. at Microsoft.ReportingServices.WebServer.ReportingService2010Impl.FindItems(String Folder, BooleanOperatorEnum BooleanOperator, Property[] SearchOptions, SearchCondition[] SearchConditions, CatalogItem[]& Items) at Microsoft.ReportingServices.WebServer.ReportingService2010.FindItems(String Folder, BooleanOperatorEnum BooleanOperator, Property[] SearchOptions, SearchCondition[] SearchConditions, CatalogItem[]& Items)
The type appears to be correct. I've tried type of "Folder" and receive the same error.
I installed the SharepointRS.msi add-in and configured the Reporting Services to the sharepoint integration mode. After the installation ,I am supposed to find a new section in the Application management of Central Administration Tool of sharepoint called Reporting services. But i am not able to find that.

I have got a sql query and converting a Crystal report to Sql report but struggling on few places.When I created the report I need to have a column where I am struggling to figure out how to add this to the column
"if {Clocked_In} = "Y" then "Yes" else if {This} then "Holiday" else if {Sick} then "Sick" else if {Absent} then "Absent" else "No"
"In Crystal four columns make into one but I am not sure how can I do it in SQL report builder.
I have to display the data in the below said formats..Current sample Data in the table and the data type is numeric(23,10)
50.00 0.50 0.00 0.00
To be displayed in the below format
1.25 0.75 0 0 1
I have to map this column in teh report and should dipslay like above.I think if 0.00 is available then it should display as 0..If 1.0 is available then it should display 1.Any value that has postive number after the decimal should display all the values example : 2.25,3.75,5.06, So in general the solution to display values like 1.75,1,0 we should not dispaly 0 as 0.00 and 1 as 1.00 and 2 as 2.00 and so on...Any Solutions in terms of SQL query or SSRS expression.
I'm modifying a report that uses a date parameter as a report filter. The original report had no restrictions on what dates may be entered, so it displayed a neat Calendar picker tool for use in selecting the date for the parameter.
Thing is, this new version needs to have the dates limited to only those available in the source data. So, when I provide a query to describe the available values in the parameter properties window, instead of the nifty Calendar picker, I get a texbox dropdown list. [insert sad sound here]
I was hoping that it would still provide the Calendar picker, but with available dates highlighted in bold or some color or the unavailable dates greyed out, something along those lines; not an unimaginative dropdown list. To define the available values, I use a very simple query;
SELECT DISTINCT Load_Date FROM Census ORDER BY Load_Date
Is there a way to get it to display a Calendar tool rather than the dropdown list, if the parameter is given a list of available dates?
I'm using Cube.My DimDate tables Datekey is integer .But client wants a calendar to set date as you see in picture .how can I change calendar value which will be input by user.
I have a table with one of the column(EmpHiredate) datatype is char(10). It has value like "20141023". I need to display this value as date format(dd/mm/yyyy) in report. Following methods i tried in textbox expression but no luck.
Error:[rsRuntimeErrorInExpression] The Value expression for the textrun ‘EmpHireDate.Paragraphs[0].TextRuns[0]’ contains an error: Conversion from string "20041023 " to type 'Date' is not valid.
Is it possible to convert string to date using SSRS textbox expression ?
I am using the following function to set the time format, however I now need to to add an IF statement into this equation.This is the current expression I am using:
I have a report that is using the following expression for one of the fields:
=Split(Fields!FromAccount.Value, " ")(1)
The format of the number is xxxxx-xxx xxxxxxxxxxxx
So the function is to grab the second section of numbers after the space. The query for this report can bring back 1 to many results which equals one to many pages.
I have an issue where the query returns three results. The first page will display the correct number, the second page displays #Error and the third displays the number.
When I run the query from Management Studio I see the numbers are as follows:
Note the first and and last lines have extra spaces which I thought would be the cause of the problem though I would've expected the #Error to appear on the first and third page rather than the second one.
When I remove the extra space for the first and third number all three pages display their values correctly.
However, there are many, many numbers in the table that have one to two spaces. These numbers are from a spreadsheet that is imported biweekly. So it was either I fix the spreadsheet before every import or I come up with a new expression to check for one or two spaces. This is what I came up with:
Now, the first page displays the number correctly while the second and third page displays with the #Error. Basically I want to say if the value contains two spaces then split at the two spaces otherwise split at the one space.
How to call a table valued functions from SSRS reports ?
Is there a way to call by selecting Dataset properties> Query >Stored Procedure radio button, If not then why our object type function is visible under this list.
I have a query where I am trying to display the most recent information about travelling method of customers using "t.collection_date". I am struggling to get MAX function working in the query.
SELECT P.id, P.forename, P.surname, P.dob, c.postcode, l.code_des, MAX(t.collection_date) FROM People p, MOT_HIST t, lk_mode_of_travel l, corresp_address c
WHERE p.ID = t.id (+) AND t.mode_of_travel = l.int_code (+) AND p.id = c.entity_id (+)
Create report with SharePoint list. Columns are displaying on the report I used out of the group SUM function and it is group by report. one group total is showing correct total and other groups are showing wrong total and showing too much big value even there is whole column is empty.where value is not in column I am using "-" with IIF function. these columns are calculating by using date difference function between two date columns. these values coming with minus value . so ABS function is also using.
Columns calculation expression:
=IIF(ISNOTHING(Fields!DateCAPackage.Value) OR (ISNOTHING(Fields!Date_CA_Application.Value)) , "-" , CINT(Abs(DateDiff("d",Fields!Date_CA_Application.Value,Fields!DateCAPackage.Value))))
we need the list suppliers in a text box,if it were a parameter, we can do it by =join(parameters!Supplier_ID.Value,",")but if the Supplier Id is a field , join (Fields!Supplier_ID.Value,",") doesnt work!how to achieve this.
