I am trying to add an optional filter on a text field in a report. I have tried setting it up in the dataset but it treats it as a required filter so if it is not populated, no results are returned. It needs to use the Like operator. Any advice?
As I was typing out a work-around to this problem, I realized an incredibly easy solution (now that I understand better how it works).
Here's what I did:
Since Hong pointed out that all filter conditions must be met, I reversed my thinking. I moved my existing "IN" filters to the query and fed the parameter directly to the query. Then I created by "LIKE" text filter on the report which a default value of "*" so it would immediately return everything.
Here's what I could've done:
Just the last part. Added the "LIKE" filter with a default value of "*" so it immediately returned everything.
I also agree that most of the time it's best to send the params back to SQL. Since that's not what the OP is asking, here is the best option I have found for doing this. And it is actually quite simple.
Add your parameter with the appropriate data type. Let's use the
example of a "City" in this case (a text/string field).
Check "Allow Nulls" on the parameter.
Add a filter to either a tablix, table or dataset.
In the expression, select the field you want to filter on. Select the appropriate operator, in my example of a data set with Cities, in the Value put in this:
=IIF((Parameters!City.Value Is Nothing), Fields!City.Value, Parameters!City.Value)
I don't think you can make an optional filter in DataSet Properties/Filters, adding filters there means returning results that match ALL filter contiditions, so it is "AND" logical relation among all filters, not "OR".
My sugguestion is to use filter in query designer of the dataset, where you can define "OR" relations to filter out data. For instance: Your_Text_Field="SomeValue" OR Your_Text_Field is Empty.
Although I agree that most of the time it is best to send the parameters back to the stored procedure or data layer to reduce the amount of data returned, I have a case where it is just as easy to do the parameter handling in the RDL file via a filter. Due to this unique situation I found this solution which gives you a way to create an Optional filter in the RDL file.

It is a great blog post with easy step by step instructions on how to create an optional filter.
Please Note: This is NOT my blog but I though this solution was great for what I needed and I hope it helps someone else when they google for "optional filter in SSRS" like I did.
I found a post which solved my problem setting the filter for a report-consumer to a) all multivalue fields being selected so the user b) could specify his/her selection if necessary.

In reports when we want to default the multivalue parameter to 'Select All' following are the steps.
Open the Report parameter window from the Report menu.
Select the Report parameter from the left handside of the window.
Select 'Multi-value' checkbox and appropriate 'Available values'.
Under default values select 'From Query' radio button'.
Select the appropriate 'Dataset'.
Select appropriate 'Value Field'.
Save the Report and select Preview Tab. You will find all the items selected in the multivalue >parameter list and the result displayed for all the selected items.

(The Post came up in the comments quite in the middle.)
You can accomplish this by using an expression on the dataset filter.

The report works for just 1 choice, but when I add more than one, it does not return anything ( no errors, just nothing in the report).
My SQL statement includes the parameter #Region
where Region_Name IN (#Region)
In the Region parameter's properties, I set to allow multiple values.
in the dataset filter's properties:
Expression: =Fields!Region.Value
Operator: IN
Value: =Parameters!Region.Value(0)
*EDIT
I removed the dataset filter as suggested.
Below are the properties for the parameter.
The available values come from another data set that is a distinct list of regions.
Your edit makes a lot more sense. To use multivalue parameters you just need to reference the parameter in the usual way, except use in within the SQL:
select cols
from table
where specificcol in #Region
And then don't have a dataset filter set, just make sure there is a reference to the Region parameter in the Parameters property page. The filtering of the data is handled by the inclusion of the parameter in the SQL, so you don't need to also have a filter on the SSRS dataset.
Instead of using a parameter to go back and forth between the stored procedure and the report, I created the parameter and used it in the tablix properties.
Expression: =Fields!Region.Value
Operator: IN
Value: =Parameters!Region.Value
When you first create the value, it adds a (0) to the end of the expression. Remove that and it works as expected.
Thank you #iamdave for the help!
EDIT:
I came back to this and was able to filter using the parameter and stored procedure.
I followed a link from a question to here: http://www.codeulike.com/2012/03/ssrs-multi-value-parameters-with-less.html
I created a dataset parameter and removed the one from the tablix properties. Then created the function provided and it worked. I did not mess with the "ALL" features in the post.
Thanks for all the tips. Brent
I have been super impressed with the way you guys think about parameters in SSRS. You can make them do all sorts of interesting things. I have a report where I want two parameter options reflected in my SQL query, option one is as list of numbers for a certain field. This is easily done via
WHERE [DDI] in #DDI
Setting up the parameter DDI to include the full list of numbers. The point I'm struggling is with the counter case. In essence I need the query to become
WHERE [DDI] not in #DDI
If the second option is picked. I think the best way to solve this is with nested parameters but I can't think with portals sorry parameters in the correct way to figure this out.
TLDR : I want a parameter solution where user can pick between 2 options the first gives them a curated list in a particular field and the second gives everything except that curated list.
You could create a drop down parameter with Include (YES), Exclude (NO) wording. Then in your stored procedure it could filter based on the value passed
WHERE (( #Include = 'YES' AND [DDI] in #DDI) OR (#Include = 'NO' AND [DDI] NOT IN #DDI))
``
When a user runs the report, they can select a multi-value parameter. I know I can use Parameters!Value.Label(0), Parameters!Value.Label(1), etc to display the each of the values based on their location within the array, but the number of the values changes based on how many values the user selects.
The report separates each value onto a separate page. I'm looking to (a) have an expression that identifies which value's info is displayed on the page, and (b) an expression that labels the tab as the value when the report is exported to Excel. I expect the same expression would work for both.
I believe I should be using Array.IndexOf(Split(Parameters!Value.Label.ToString(), ","), Parameters!Client.Label), but just get #Error as the output when the report renders. I'm not sure, but it seems like the Array... expression would only identify the location within the array.
Could someone offer some insight into where the syntax is wrong? I'm not sure if the issue is syntax or it's an issue of how to specify which dataset to use in the expression.
Thanks.
This is what you should use
=Join(Parameters!CSR.Label, ", ")
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)
Customer wants me to repeat the parameter values in the page header of the report. But if they just choose "Select All" on a multi-valued parameter, they want the text "Any" listed.
For example, one parameter has a fixed set of 9 values. I hard-coded the expression for a text box to:
="Room Size: " &
iif(Parameters!pRoomCap.Count=9,
"Any",
Join(Parameters!pRoomCap.Value, ", "))
How can I do this if the parameter source is a query of unknown size?
Try this out. You need to compare the total number of parameters in the dataset to the count of selected parameters. The following assumes that your multivalue parameter is using a dataset called "dsRoomSizes"
="Room Size: "
& iif(Parameters!pRoomCap.Count = count(Fields!pRoomCap.Value,"dsRoomSizes"),
"Any",
Join(Parameters!pRoomCap.Value, ", "))
This expression will work in the page header/footer.
UPDATE
In the interests of finding a solution to your problem, the following should work for you. It feels hackish and I encourage you to keep research alternative methods but this will work:
Create a second multivalue parameter and name it something like "pRoomCap_hidden".
The source of the parameter is the exact same query
In the parameter properties, setting the default values to the same query
Important: Set the parameter visibility to hidden
This will create a second multivalue parameter in your report that is exactly the same as your initial multivalue parameter only this parameter list will have all values selected by default.
Enter the following expression in a textbox in your header:
=IIF(Parameters!pRoomCap.Count = Parameters!pRoomCap_hidden.Count,"All",Join(Parameters!ReportParameter1.Value,", "))
The above will compare the selected values in each parameter list. If the lists contain the same selected values then that indicates that "All" have been selected in the first list.
Like I said, it is hackish but it definitely works. Until you are upgraded to 2008, this might not be a bad workaround for you.
Can you compare the count of the parameter to the count of the dataset you pull the parameter values from?
I unioned my dataset for the parameters with one which I created manually with a "select" statement - I was then able to force the value to be something like -1 or null.
Then simply check if the parameter contains -1 or null and replace the value in the header with the replacement text.
BTW- I am now using SSRS 2008 R2 and this solution worked for me. My report uses three datasets; but only one in the tabilx that I needed to hide a row in. After long hours of searching and many, many, many unhelpful for wrong answers; the solution of creating a identical parameter only hidden (I marked it as internal) and then comparing to the exposed one is brilliant and easy.
Thank you very much!
