I laid out the report, and I do a query that returns 30+ rows for a given period of time. One for each workflow. Now, I want to take that dataset (so the query only runs once) and define 6 datasets from it that filter it based on a single selected row. I will populate 8 boxes on the form for each of those datasets.
It appears that when you create a new dataset, it wants to go back to the datasource and ask you about all the data from that one again.
I was able to create a dataset that is a filtered view of the query and figured I could live with creating 6 datasets that ran the query each time filtering it differently each time. So, I need to do a 'copy' on the dataset and 'paste' it back in as a new dataset that is the same as the other one except with a new name.
I also need to set the default values for the Start/End date to be the 1st of last quarter, and the first day of this quarter. Is there a way to create calculated default values or do I need to do a query to return that?
if you are using table objects to create your report. you could use just 1 data set and add your filters to the table accordingly. just go to tablix properties>> filters tab.
for default values you can create expressions like for the first day of the current quarter:
=switch(DatePart(DateInterval.Quarter,today()) = 1, cstr(year(today))+"-01-01",
DatePart(DateInterval.Quarter,today()) = 2, cstr(year(today))+"-04-01",
DatePart(DateInterval.Quarter,today()) = 3, cstr(year(today))+"-07-01",
DatePart(DateInterval.Quarter,today()) = 4, cstr(year(today))+"-10-01")

In my Anylogic model I succesfully create plots of datasets that count the number of trucks arriving from terminals each hour in my simulation. Now, I want to add the actual/"observed" number of trucks arriving at a terminal, to compare my simulation to these numbers. I added these numbers in a database table (see picture below). Is there a simple way of adding this data to the plot?
I tried it by creating a variable that reads the database table for every hour and adding that to a dataset (like can be seen in the pictures below), but this did not work unfortunately (the plot was empty).
Maybe simply delete the variable and fill the dataset at the start of the model by looping through the dbase table data. Use the dbase query wizard to create a for-loop. Something like this should work:
int numEntries = (int) selectFrom(observed_arrivals).count();
DataSet myDataSet = new DataSet(numEntries);
List<Tuple> rows = selectFrom(observed_arrivals).list();
for (Tuple
row : rows) {
myDataSet.add(row.get( observed_arrivals.hour ), row.get( observed_arrivals.terminal_a ));
}
myChart.addDataSet(myDataSet);
You don't explain why it "didn't work" (what errors/problems did you get?), nor where you defined these elements.
(1) Since you want both observed (empirical) and simulated arrivals per terminal, datasets for each should be in the Terminal agent. And then the replicated plot (in Main) can have two data entries referring to data sets terminals(index).observedArrivals and terminals(index).simulatedArrivals or whatever you name them.
(2) Using getHourOfDay to add to the observed dataset is wrong because that just returns 0-23 (i.e., the hour in the current day for the current model date). Your database table looks like it has hours since model start, so you just want time(HOUR) to get the model time in elapsed hours (irrespective of what the model time unit is). Or possibly time(HOUR) - 1 if you only want to update the empirical arrivals for the hour at the end of that hour (i.e., at the same time that you updated the simulated arrivals).
(3) Using a Variable to get the database value each hour doesn't work because a variable's initial value is only evaluated once at model initialisation. You want an hourly cyclic Event in Terminal instead which adds the relevant row's value. (You need to use the Insert Database Query wizard to generate the relevant Java code for the query you need in the event's action.)
(4) Because you have a database table with specifically-named columns for each terminal (columns terminal_a and presumably terminal_b etc.) that makes it slightly more awkward. (This isn't proper relational table design where, instead of 4 columns for the 4 terminals, you'd instead have two columns for terminal_id and observed_value with a row for each time period and terminal combination.)
So your database query expression (in your Terminal agents) will need to use the SQL format (not the QueryDSL format) so that you can 'stitch in' the correct column name into the SQL.
I have an SSRS Report using a Table.
You can select multiple Clients and Periods and for every pair there will be a row in the table. So 2 Clients * 3 Periods = 6 rows.
Now... there are some cells that are more complicated than having a single value and I want to place a subreport inside these cells. The Subreport will take the Client and Period for that particular Row as params.
This is where the issue comes in. The Parameters will not pass properly.
I can put Parameters!ClientID.Value(0) as an expression for example and it will pass the first ClientID properly but if I just put Parameters!ClientID.Value it breaks... And I want the Client/Period for the current row.
But how is it that I can't pass the params but CAN fill a new dataset for every row based on that Client/Period pair??
Note that I'd really prefer not to have to edit the SP that builds that dataset to return the Client/Period itself. Sure that would work.. but WHY would that be needed when I have the Parameters?
Any ideas? I'm doing this in a Visual Studio Report Project.
If I've understood correctly you don't need to use the parameter. You need to use the value of the field from the dataset. So if your table shows client and period then the parameter values passed in would be =Fields!Client.Value and =Fields!Period.Value
Client Period SubReportCell
Bob 2017 "subreport here passing in Bob, 2017"
Geoff 2015 "sub report here passing in Geoff, 2015"
You should just be able to choose these from the dropdown lists in the subreport setting dialogue box.
I have a SSRS report I'm working on. What I would like to do is get the value of one field from its own dataset and subtract the value of another field from a different dataset. I can do this; however, the values are grouped so rather than giving me an individual value it gives me: (sum of all completed) - (sum of all completed the previous year).
Here is my expression I am using for the column "Compared to last year"
=SUM(Fields!Completed.Value, "MTDSales") - SUM(Fields!Completed.Value, "MTDminus1")
"MTDSales" and "MTDMinus1" are 2 seperate datasets. MTDSales Dataset is the current months sales outcomes grouped by company MTDMinus1 dataset is last years figure for this current month as i am comparing the 2 months separately.
I had to do this in a report where I was pulling current data from one database and older data from a data warehouse and combining. You will need to do a few things:
1. Establish a match field
This can be as simple as a single column. If you need to match on multiple fields you will need to add a calculated field to each dataset that you can match on. Assuming you need to match on company and financial year and each dataset returns one year of data, this might look something like match_id (assuming numeric values - otherwise you might need to use | or something as a separator):
`="A" & Fields!fin_year.Value & "B" & Fields!cust_id.Value`
2. Retrieve the data to the source field.
In your tablix add a column as you have to hold the looked up value:
=Lookup(Fields!matchId.Value, Fields!matchId.Value, Fields!Completed.Value, "MTDminus1")
3. Use the data
Now you can aggregate the data or do whatever further calculations you wish as if the field was part of your original dataset.
I'm all about recycling-)
I have report that user want to run for selected number of month back (let say from 1 to 12).
If they selected 6 month back (Jul-13 thru Jan-2104, then I need to produce 6 pages with monthly report on each of them, and sp is the SAME for all reports just different time params.
How I can reuse my code??
For now I have 12 Tablix(s) with New Page=START, Hide condition set based on datediff(m,startDate,endDate) individually for each Tablix.
Then I need to run same sp with diff params, can I add some dynamics into it? or I better to have 12 sp(s)?
Thanks
Mario
You can achieve this with a single dataset and a List Report Item with an embedded Tablix:
Set the List Grouping to Group/Sort first by: =Year(Fields!YourDateField.Value) and then by =Month(Fields!YourDateField.Value).
Set the Page Breaks on the List Grouping to "Between each instance of a group".
Drag your Tablix inside the List Report Item.
Let me know if you need more detail.
I have a MVC application in which I need to display the data from 3 tables. I am using entity model for it. Out of these, in 2 I have made the association:users and payment table.
And 3rd table month_<monthid> is created every month to store the users to whom the magazine is sent. The table name month_<monthid> is generated dynamically by selecting the month so in order to fetch the data I have used ExeuteStoreQuery. For small amount of data the listing is fast but for large amount it is very slow.
Now I have created a class to bind to grid which will include all the fields from the 3 tables to display.
But here when I am getting the large volume of data about 12000 then it is taking about 30 min to go through the loop and assigning the data to the class object and then adding to the list of the result which is finally binded to telerik grid.
I am hereby attaching the sample code using a link. Is there any direct way to bind the query result of joined tables to grid instead of going through the loop and preparing the list for the model class I think that will save time.
The code block of preparing the list using the Executestorequery is under the function GetuserList().
foreach (var r in result)
{
Result objresult = new Result();
var paymentresult = from sub in dtpayment.AsEnumerable() where sub.Field<int>("user_id") == r.user_id select sub;
if (paymentresult.Count() > 0)
{
objresult.amount_paid = paymentresult.FirstOrDefault().Field<decimal>("amount_paid");
objresult.magzine_id = paymentresult.FirstOrDefault().Field<int>("magzine_id");
}
objresult.address=r.address;
objresult.email=r.email;
objresult.name=r.name;
objresult.user_id=r.user_id;
objresult.month= smonth;
lstresult.Add(objresult);
}
This code block of for loop is taking very time where I am using ExceuteStoreQuery.
But I have observed that simply by joining the users and payment table using LINQ query to get all the 12000 records i.e no involvement of month table the result is appearing faster.
So,can you suggest any way to improve the performance of my application?
Also include the database structure with the sample code.

Nobody in the world wants to see 12,000 records. You should look at implementing paging & searching functionality.
