Can I use WHERE clause in an SSRS expression? - reporting-services

I saw the post on WHERE clause in SSRS expression. I am also trying to do a where clause, but in a different way. I need to show ItemDesc when ItemId = 4. I set a parameter so that it will always equal 4 for this cell. Now I just need the matching description field. I cannot hard code it because the description may change one day. Is there a way to associate the two fields?
=IIF(Parameters!ItemID_4.Value = 4, Fields!ItemDesc.Value,"")
I am converting from Crystal Reports to SSRS. This first image is the output from CR. I only need to show that ItemDesc in that top left cell.
This next image is from SSRS. It is not limiting the descriptions. It seems to be doing what my expression is saying. ItemID = 4, so display all ItemDesc values but the two fields are not associated right now. I need it to only show the matching value.
Thank you for your help.

I cannot hard code it because the description may change one day.
You are hard coding the parameter anyway by trying to do it that way. I don't think you need a parameter to achieve the result unless you are restricted from adjusting the dataset query.
If you are using an embedded SQL query for your dataset, I would just put a filter in WHERE clause: WHERE ItemID = 4
Another way if you can't adjust the query is to go to Report Data view > Right click on the dataset for your table, "Dataset Properties" > go to the "Filters" tab and add a filter with these settings: Expression = ItemID, Operator = "=", Value = "4" (or "#ItemID" if you want to keep your parameter).

Brining row where column valus is null

I have a store procedure which brings the data as shown below . I'm new to SSRS reporting, I would like to show only those row where "email" column is null. How can i achieve it in SSRS ? As i mentioned I'm very new to this , any screenshot will help me a lot. Thank you for your time.
For this problem, you'll want to change the row visibility to hide rows with a value in that column. I assume you're using a table or matrix to layout this data. You'll want to right click on the row where your data fields are entered. Specifically, the grey box at the left of the row.
From there, you'll need to select the option to Show or hide based on an expression.
And finally, you'll need to enter an expression that finds the values in the email field. I'm not exactly sure what the field names are called but something like the following expression should do it.
= Not IsNothing(Fields!EmailField.Value)
This will check the field where you get the email value with a built-in function of IsNothing. Additionally, since you want fields that do not contain values, the Not keyword reverses the results. If the function evaluates to true and a value is present, the row will be hidden and vice versa.

SSRS Filter with a different column from a different dataset

I want to filter my column, let's call it AllStudentID from dataset1 with another column from a different datset.
Dataset1 had many column such as AllStudentID, Class, Time, Location.
Dataset2 has other columns but i'm focused on a similar column called OnCampusID.
I've tried looking into using a filter but since the report itself has the columns from Dataset1, i run into an issue where if I select the column in dataset2, it always gives a First(OnCampusID). And I don't want that.
I looked into IIF() but again, i'm using a column from a different datset plus if let's say that they are NOT equal, I don't want to display anything, instead of putting something there. I know that you have to put a result if true and a result if false.
If I"m thinking of it in terms of SQL statements, it's like having a WHERE clause WHERE AllStudentID=OnCampusID.
I tried running a Parameter but I don't want the select part on the top but rather have the report filtered already.
Am I missing something? I know it has to be simple.
Mind you, the following example above is just an example i made up, not the real thing.
Assuming that each OnCampusID only appears once in Dataset2 then you can do a Lookup expression to filter it:
=IIF(IsNothing(Lookup(Fields!AllStudentID.Value, Fields!OnCampusID.Value, Fields!OnCampusID.Value, "Dataset2")), False, True)
If OnCampusID appears more than once in Dataset2 then do the same thing using LookupSet.
To get the graduate field from Dataset2 just to a Lookup in the Value of the cell, like so:
=Lookup(Fields!AllStudentID.Value, Fields!OnCampusID.Value, Fields!Graduate.Value, "Dataset2")

SSRS expression issue using iif function

I have a data set that is returning two properties, a name and a total units. I am trying to set an iif expression on a data bar where iif(field!Name.Value = "Name", field!Total.Value, 0)
this is not working I get an error of rsFieldReferanceAmbiguous, the fields refers without specifying a dataset aggregate. And the only option that it gives me as an aggregation is First, but I do not want to get the first name, I want the bar to display the total units base on the name field that is in the iif expression.
rsFieldReferenceAmbiguous refers to trying to match something that is not in local scope. Therefore you have to aggregate it. You are probably wanting something like this:
=Sum(IIF(Fields!Name.Value = "Name", Fields!Total.Value, 0))
The function you are trying to use would be better suited to a calculated field in your dataset. Then you can just refer that that field in your report. This allows you to filter the data line by line instead of by groups.
Right-click on the dataset and go to Dataset Properties.
Go to Fields.
Click Add then Calculated Fields.
Enter the name of the field and then the expression here.
Make sure your tablix has the dataset specified under General -> DataSetName on the properties pane. If you have more than one data set on the report you will need to specify which data set your reffering to like so:
(Fields!Name.Value, "NameDataSet")
If your useing tables you may need to ckeck if you have grouping and if so how your grouping your data.

SSRS Multi Value Parameter. Check whether "Select All" is selected

I have a multi value parameter in my SSRS Report. I want to find out whether (Select All) is checked in that parameter.
In other words, whether all the values in the parameter are checked or only some values are checked.
Is it possible?
I am able to find out number of selected values through Parameters!Parameter.Count. Is there a way to find out total of items in that parameter?
In case anyone is still having issues doing this, I just coded this easy fix.
=IIF(COUNTROWS("dataset").Equals(Parameters!parameter.Count),"it is equal","this is not equal")
For the specific use-case of showing the selected filter on your report in a textbox, here's the expression that will show "All" if "(Select All)" is selected, otherwise it will show all the selected values as a comma-separated list:
=IIF(
Parameters!YourMultivalueParam.Count = countrows("YourDataset"),
"All",
Join(Parameters!YourMultivalueParam.Label,", ")
)
(split onto multiple lines for readability)
countrows reference: https://technet.microsoft.com/en-us/library/dd255215.aspx
Credit to other answers, just want to extend them for this common scenario.
Your approach sounds good: I would make the options for the parameter come from a dataset.
Then you can use =COUNTROWS("DataSetName") to return the total number of options for your parameter and compare this with Parameters!*Parameter*.Count as you suggest.
I also faced this problem and I solved it this way.
I have one multivalued parameter named "Carrier". Then I have added one parameter "CarrierHidden" which is same as "Carrier" only thing is I made its Visibility as Hidden.
="Carrier=" & Switch(Parameters!CarrierHidden.Count = Parameters!Carrier.Count, "All",
Parameters!Carrier.Count > 1 And Parameters!CarrierHidden.Count > Parameters!Carrier.Count, "Multi",
Parameters!Carrier.Count = 1, Parameters!Carrier.Label(0))
The easy way will be to count the number of the selected parameters and compare them to the dataset
=IIF(Parameters!company_number.Count = CountRows("Dataset1"), True, False)
The problem is if you're trying to pull something for another data set then cross referencing the row count in another dataset won't work. You will have to go with what the previous post states. Create an internal parameter of the exact type and assign the default value to the entire dataset. That way you have the max count of the rows since the hidden parameter.count = rowscount. That way you can use it within another dataset also provided that dataset is AFTER the first one is populated.
According to Microsoft's SSRS help search:
=Parameters!<ParameterName>.Count
Returns the integer value 1. For a single-value parameter, the count is always 1.
I verified this does indeed work, check the integer returned for the built-in parameter count field.
Allow multiple values on a parameter selection. Checking the value of the above field will let you know how many values the user actually chose.
In my situation, I allow multiple values on company number. This gives users the ability to choose one company to report on or several at once. Per client request, if they choose more than one, display data horizontally. If only one company is chosen in the parameter list, show the data vertically and hide the other tablix.
So my visibility show or hide expression looks like this in the one tablix:
=IIF(Parameters!company_number.Count > 1, True, False)
and like this in the other:
=IIF(Parameters!company_number.Count = 1,True,False)

Suppress the duplicate values in group, SSRS Reports

I have an SSRS report
where the date should be grouped by project category
the project code in the category is repeating in side the group how do I suppress the value
Please help me to get an idea.
Thanks,brijit
You can also hide fields by putting an expression in the Hidden property like this:
=Fields!ProductCode.Value = Previous(Fields!ProductCode.Value)
So if the value in the previous record is the same as this one, it will hide the field. You must sort the dataset correctly for this to work. In your case I think the sorting would be Date, ProductCategory, ProductCode.
In the past I used this often together with expressions for field borders to group the output visually.
I think there is one option hide duplicates in properties in ssrs. so you will check in that option under the project category group.so that you can hide the duplicate values and get unique records. first u create one group based on project category in fields properties and then check in that hide duplicate option under that group.whenever you check in that option it will high light one drop down list showing containing group or dataset there you select your created group.
This is a bit late for you brijt, but what I do is edit the textbox properties for that field, in the font tab enter an expression for Color as follows:
=IIf(Fields!ProductCode.Value = Previous(Fields!ProductCode.Value), "White", "Black")
...assuming your background is white this will effectively do what you want.
I think it may be an issue concerning the way you are grouping the dates. Do you have the grouped with time on them as well but suppressing the hours in your output?
For example:
12-5-2010 12:00:00
12-5-2010 13:00:00
if you strip the times off in how you see them but not how you group them, they would show up duped.
