I've got two tables binded to two different datasets. I'm trying to reference one of the rows from one of the tables (Table A) from Table B.
Since it's outside the scope of the table, I can't use ReportItems![Textbox name].Value
Any ideas?
You can use the SSRS Lookup() or LookupSet() function to retrieve the data directly from the other dataset.
I found the MSDN pages a bit unclear, the syntax goes like this:
=LOOKUP(Fields!sourceMatchingField.Value,
Fields!targetMatchingField.Value,
Fields!targetReturnField.Value,
"Name of Second Dataset"
)
Fields!sourceMatchingField.Value is from the dataset that is
currently in scope.
Fields!targetMatchingField.Value is from the other data set you need to get information from and equals Fields!sourceMatchingField.Value.
These two parameter values for the Lookup function make the join criteria for the two datasets. They can be more complicated than simply two field references (such as using functions to manipulate on or both), but I'm just showing the simplest way to do it.
Fields!targetReturnField.Value is the field from the second dataset that you want to return. This should just be a reference to a field.
"Name of Second Dataset" is just what you've named the other dataset that you're joining to.

In SSRS report I have two data sources from two different servers. I have a dataset for each data source and would like to return in a tablix the ids that are in dataset 1 but not in dataset 2.
So if dataset 1 has ids 1,2,3,4,5 and dataset 2 has ids 1,2,3 the report should display 4 and 5. I cannot link the servers. Thanks.
There are several ways to do this.
Common Lookup method
This is the way most people would probably do this
Use the Lookup() function.
Set the tablix row's hidden property to something like
=ISNOTHING(
Lookup(Fields!IDa.Value,Fields!IDb.Value,Fields!IDb.Value,"Dataset2")
) = False
The above, for clarity, assumes the ID column in dataset1 is called IDa and the ID column from dataset2 is called IDb. It will stil work if they have the same name (e.g. 'ID')
Note: Dataset name must be in quotes and is case sensitive.
Using this method returns all the rows and simply hides the ones that do not match your criteria. This may not be ideal if you're exporting the data. If not, see the alternative version below.
Alternative method
For reasonably small datasets - parameter method
... and because I thought it was an interesting approach...
This second method uses a hidden parameter and is easy to setup assuming you have a reasonable small number of records.
Using your example, create a parameter called List2 and set its default and available values BOTH to your Dataset2 query (from your example above). Make the parameter multi-value. You can make this parameter hidden once it's working.
Now Your Dataset1 query can be a simple query like this,
SELECT * FROM Table1 WHERE id NOT IN (#List2)
#List2 will contain the values from datset2 (1,2 and 3) so the query will return only the remaining values.
Note I named the datasets to match your example but the datasets must be created in the order above.
I am generating a table in SSRS based on the selection made by the user on two filters: Filter1 and Filter2 (say). The table so displayed has 10 columns and I wish to add filter option listing all available values for that column for all 10 columns.
Basically, I am trying to replicate the Excel functionality of filtering down data on each and every column.
Please note that I tried creating a new data set and a parameter taking all distinct values for a particular variable. However, I am still not able to get the desired results by filter the tablix on that parameter
Is there a way I can do that?
You'd need to make a new dataset that is a smaller version of your main dataset. It would need to return all potential values for the column(s) you want to filter in a single column to be used in a parameter.
Without seeing the design of the report or the dataset itself it's quite hard to be more specific.
I have four datasets that get information for four different things (a unique set of fields for each one), but that can be joined using a field they share. I need to get them all into a tablix that will have four rows, one for each dataset per the linking field. How do I do that?
Currently I can only put in values from one dataset.
Often the best idea would be to create a query that joins the datasets in the sql. If that is not possible, you can look into using the Lookup function to find info from other datasets in your report. The related Lookupset function is able to retrieve sets of information and may be useful as well.
I want to get data(dynamic) according to the data in another dataset and put the result in textbox of the different dataset.
Right now, the data I get is static and I tried to use many expressions but no avail.
Problem lies in editing textbox expression. Since I am getting data from different dataset, it always ask me to have dataset aggregate function in my expression. If I specified the dataset from where I am getting the data, then, I cannot make it dynamic - and I get the undesired result.
And another way out that I attempted is merging the data sets into one rather than having multiples and use it only but this was unsuccessful.
How can I make it work to get the result that I want:
By the way, the textbox and the tables are in different scope. I have tried to combine them in one scope too.
Getting data from another dataset requires an aggregate function because it can't tell what data you want from that dataset so it forces you to aggregate it so it can return a specific value rather than an entire list of values.
I think what you are after is the Lookup function. Lookup allows you to look up a value from another dataset based on a value in the table's dataset. To give a simplistic example, let's say your table was of employees and you had a department id on that table and another dataset called "Departments" which had an id and a name. You could look up the department's name using the following expression:
=Lookup(Fields!DeptId.Value, Fields!Id.Value, Fields!Name.Value, "Departments")
This uses the current table's dataset's DeptId field to look up the Departments dataset by the Id field and return the Name field.
=Lookup(First(ReportItems!EmpID.Value),Fields!EmpID.Value,Fields!Dept.Value,"dataset_which_u_retrieve_the_data_from")
Problem solved!By using reportItems instead of Fields because I am retrieving one data only,not the whole field.
Thanks guys for helping me out.
I have two different-2 datasets with different fileds which are getting populated through two stored procedures with same input parameters.each datsets have different colums and no of columns around 180,my concern is how will i use these two different datsets in single report with two differents fields(two differnt tables).for one dataset i have used report wizard,but not able to figure out for the second dataset.Please suggest for the same..
You can use two different datasets in different reports regions on one Report. For example, If you have two datasets, lets say DS1 showing EmployeeDetail and DS2 showing SalesInfo. You can use them separately in two tables one showing Employees Details and other showing Sales Info. If you plan to merge this data and use it in one table, These are option.
Recommended option : Re-write your query to create single dataset containing possible data you want to show in tabular fashion.
Would work but would be lot slower : Use DS1 in a table in Main Report where each row contains Epmloyee Detail, Wihtin that Row call a Sub-Report passing EmployeeDetail's key which is related to a column in SalesInfo. Create sub-report showing SaledInfo data, call this report in main report passing key value from DS1 to this sub-report.
Specify data set name in third column
Example:
=First(Fields!fieldname.Value,"DataSet1")
Using two different or multiple datasets in a report is not a problem at all, as long as they do not belong to the same data region (charts, tables, etc.)
In addition to Ron's answer, if you are looking to get data from different datasets in one data region, you could also use Lookup or LookupSet in the field expressions.
Additionally, you may also create one dataset and filter out some data from it in data regions. For example, if you have one big dataset of all employees, and you would like to display all employees that joined in the year 2012 in a table, you could filter out the dataset using Filter properties of table.
You can simply add multiple table in your report , and change datasetName from tablix properties for each of your table .
you will also need binding source to fill that dataset .
this.invoiceTableAdapter.Fill(this.ARQutationDataSet.invoice);
