How can I find a specific value in an object? - reporting-services

I have a Parameters that is an object and contains a few value :
key
Value
0
Apple
1
Juice
2
Banana
So If I do Parameters!MyParam.Value(0) the result is Apple, and Parameters!MyParam.Value(1) the result is Juice, etc.
What I want to do is to see if my object contains a value like Banana and return true if it does.
Is it possible ? I didn't find anything the net. The closest thing that I found is inStr but it only works for strings...

A few things to point out here...
In SSRS a parameter is made up of a Value and a Label. What you describe as the Key would be the Value and what you describe as the Value would be the Label.
You can reference the Parameter's Label property using Parameters!MyParam.Label
It's not clear from your question but I assume you want to search your parameters to see if a specific value has been selected. If so then you can do that like this...
For this exmaple I have added the parameters values/labels manually but you can do this however you need.
Next I added, for demonstration purposes, some labels and fields to the report as follows.
The selected parameter's expression is
="|" & JOIN(Parameters!MyParam.Label, "|") & "|"
The 'contains banana' expression is
=("|" & JOIN(Parameters!MyParam.Label, "|") & "|").Contains("|Banana|")
The JOIN simply joins all the selected parameter labels togther, using the pipe symbol | as a delimiter. I then add a | to the start and end so the can search for |searchterm|. This avoids errors if, for example, you had "Pineapple" and "apple" in the parameter list and searched for "apple", it would show true even if only "pineapple" had been selected. By searching for "|apple|" we avoid this.
Once we have the join results we can then use the VB function .Contains() to search for what we want.
If I run the report and select all values I get this
If I select only Apple and Juice I get this

What is the SSRS Multi Value Data Type and how to use

I have a multi-select.
I think the underlying datatype is int || array(int). This is pretty frustrating that you have to do a check to see if a multi-value is present before jumping into an index. But how does this value get passed to SQL?
It's easy enough to use in a IN (#variable) statement. How else can it be used? Is it a string or a table. From my investigations it appears to be single table row with many un-named columns but I'm not really sure.
Finally, when you want to simulate a multi-select in a query inside visual studio, for example to "Refresh Fields" how do you do that? For example "1,2,3", {1,2,3} or #{1,2,3}. It's not (123) because that is -123.
It dpends what you are trying to do and in what context.
As you said, if you have a datset query that is a SQL script (as opposed to a stored proc) then you can use IN(#paramName). In this instance SSRS take the parameter values (not the labels) and injects them into the sql statement as a string e.g. '1,2,3'. The result would be IN(1,2,3). If you want to pass in a list of, say, countries then you would have to set the parameter values to be the same as the parameter labels So rather then Value =1, Label = Spain you would have Value = Spain and Label = Spain. Used in an IN() would generate something like IN('Spain', 'France').
If you try to do the same with a stored proc e.g. EXEC myProc #myParam, then the parameter values would be passed as a sing string which would then need to be split out by the proc.
If you just want to get a list of selected parmeter values or label shoing in your report then you can simply do something like
=JOIN(Parameters!myParam.Value, ",")
or
=JOIN(Parameters!myParam.Label, ",")
where "," is the delimiter
If you pop this expression in a text box, you'll get a list of the selected parmater values/labels
I think it's a kind of madness but I found a workaround to get a table of values from the results from SSRS. I query the IDs against a source table using IN(). I hope there is a better way of doing this?
SELECT [TblFeeBillingCycleID]
FROM [TblFeeBillingCycle]
WHERE [TblFeeBillingCycleID] IN(#intCycleId)

Missing field formatting

I am having some trouble getting around missing fields in my report designing.
Many of the users on the database have a missing Address Line 2.
The report is being rendered using list items like this:
Name
Address 1
Address 2
Town
Postcode
So if Add2 is missing it appears like so:
Name
Address1
Town
Postcode
Is this possible using lists within Report Builder 3?
See attached image.
My recommendation would be to use row visibility to hide rows where the corresponding field is empty or missing. I don't know whether your data has "" or NULL behind the scenes so this is generic advice.
Here is a great set of examples of the types of formulae you can use:
http://msdn.microsoft.com/en-us/library/ms157328.aspx
If the field is NULL you can use the is nothing evaluator like
=(Fields!Sales.Value is NOTHING) to return a TRUE or FALSE, alternatively you can do a check of the string length using the function LEN() to see how long it is and if it is 0, hide the row.

SSRS Ignore Filters Based on a specific Filter used

Good day
I have a SSRS report that has 4 filters.
One of the 4 filters is a "Search Parameter".
When the user uses the "Search Parameter" (field/filter, types something in), I want to ignore the other three filters despite them having values or not.
I've tried CASE/SWITCH statements in the Expression of the Parameter (DataSet Properties), but no luck.
Does anyone have an idea on how I can get this done
The Filter is quick and convenient but only allows AND relationships between the filter criteria and you want an OR relationship here.
The good news is that you can make more complex filter logic by using expressions. We will create a boolean filter expression that evaluates to whether you want to filter the row or not and compare this to True.
Have only one filter criterion and click the expression editor button. Make the expression something like:
=IIF(IsNothing(Parameters!SearchParameter.Value), Fields!Field1.Value = Parameters!Field1Parameter AND Fields!Field2.Value = Parameters!Field2Parameter AND Fields!Field3.Value = Parameters!Field3Parameter, Fields!SearchField.Value LIKE "*" & Parameters!SearchParameter.Value & "*")
Make the expression type be Boolean, the Operator = and the Value True.

Need Help on SSRS SPLIT function

Hi All I need your advice,
1) I have a dynamic string which changes each time.
for example today the string will be "ItemA,ItemB,ItemC" and tomorrow it will be "itemA,ItemB" only.
2) I have an SSRS report which has 3 columns
3) I want to split this string "ItemA,ItemB,ItemC" and want to show split substrings in these 3 columns of ssrs table. the Delimiter is "," (comma)
4) I had used
=Split("ItemA,ItemB,ItemC",",").GetValue(0) in the first column of the report
=Split("ItemA,ItemB,ItemC",",").GetValue(1) in the second column of the report
=Split("ItemA,ItemB,ItemC",",").GetValue(2) in the third column of the report
5) everything works fine until my string is "ItemA,ItemB,ItemC" ,
BUT WHEN MY STRING CHANGES TO "ItemA,ItemB" I am seeing "#Error" in the third column.
I understood the error, for
=Split("ItemA,ItemB,ItemC",",").GetValue(2) we don't have any value because the string now has only 2 values after applying split function.
Is there any way i can avoid #Error in the third column.
NOTE: I have to compulsorily use 3 columns in the ssrs report.
I had tried using =Replace(Split("ItemA,ItemB",",").GetValue(2),"#Error","NULL") in the third column but that also wont worked.
This is similar to the divide by zero issue in using IIF statements. The problem is that IIF is not an expression, it is a function with three parameters:
IIF(Condition, ValueIfTrue, ValueIfFalse)
Accordingly, ALL parameters are evaluated BEFORE being passed to the function, which results in the error because the erroneous expression is still evaluated even when the condition should mean that it isn't.
I can't see a way to use the usual workaround tha solves the problem in the divide by zero case. What we need is a real language that doesn't have this problem. Fortunately, this is availble in the form of custom code.
Do the following:
Right-click on an area of the report surface that has no report objects
Select Report Properties
Click on the Code tab
Insert the following code:
Public Function ExtractCode(Combined As String, Position As Integer) As String
if (Split(Combined, ",").Length >= Position) Then
Return Split(Combined, ",").GetValue(Position-1)
Else
Return ""
End If
End Function
Click OK and go back to the report
Right-click on the cell you want the expression in and click Expression
Insert the following expression:
=Code.ExtractCode(Fields!Combo.Value, 3)
The value 3 is the "column" that you want to extract from the Combo field, so to get the second "column" you would use 2. If there isn't a column at that position, an empty string is returned.
you could change the visibility of the 3rd column to hidden if the name returns an error
You can append a dummy element and then split:
yourText = "ItemA,ItemB"
item0 = Split(yourText & ",", ",").GetValue(0)
item1 = Split(yourText & ",", ",").GetValue(1)
item2 = Split(yourText & ",", ",").GetValue(2)
item0 = ItemA
item1 = ItemB
item2 =

SSRS: Can I know if user selected "ALL" in multivalued param?

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!
