I am trying to make a multi-value parameter that's based off of a dataset to use another field for the Default values. I created a dataset for the parameter with the users and another column that substitutes an X for the username (op_user) if it's an automation account. Unfortunately, it's not selecting any of the usernames.
I have checked the data and there are no NULL values. I have ran a query to make sure that the columns are equal (the Match column).
It works fine if I use the same op_user column for the default values but none are selected if I use the OPuser column.
Can anyone give me an idea of what else I can try in order to make this work?
The problem that I see is that your "Default Values" column of OPuser now contains an 'X' value that is not in your available values. No values will be selected unless all the default values actually exist in the available values column.
I would suggest that you solve this problem with a second dataset. Just use the logic to generate the OPuser column separately and then use that dataset as your default values. That way you don't have to worry about the 'X' values that you don't actually want to be selected.

I have several filters in the SSRS report.
I would like to use multiple-selection but I have blank values.
What can I do when I want to choose Select all and in this case I want to include all values (Blank and Null)?
I would replace the Blank and Null values with a dummy value e.g. 'Unspecified' (assuming it's a text column.
Ideally, that happens upstream from SSRS for best performance and consistent results. If necessary you might have to derive that as a column in your dataset SQL, or even a dataset calculated column with an SSRS expression as a last resort.
Note your dataset driving the parameter must stay consistent with the dataset(s) providing the report page data.
I am designing a report for SSRS. I want the user requesting the report to be able to specify, when they generate the report, from a pre-defined selection some values which should be displayed in a tablix on the report.
I have therefore created a multi-value parameter and populated the Available Values with the options I want the user to be able to select from, and, as expected, when the report is generated the user is able to select one or more of these values.
However, what I now want to do is include a tablix in the report, and display a row for every value in the multi-value parameter that the user selected, with the value displayed in the first cell of the row.
If the values were coming from a data table this would obviously be easy. I've also found answers on how to show all of the selected parameter values in a single textbox using the JOIN function, but I don't want to do that.
The only solution I can think of is to replicate the list of available values in the multi-value parameter in a tablix manually, and link the visibility of each row of the tablix to the selected state of the corresponding value in the multi-value parameter, but that's not very elegant and increases the effort involved in maintaining the report definition.
Any ideas on how to do this? I know the selected values from the parameter simply form an array, but I can't see how to bind a tablix to any data that isn't in a dataset, or how to create a dataset from the parameter values.
Considering that a tablix sources from a dataset, I did some experiments to see how to create a low maintenance solution for you.
Option 1: Create a data set with hard-coded options to match your multi-value parameter and select those options WHERE they exist in the parameter.
Example:
SELECT val
FROM (
SELECT 'opt1' as val
UNION SELECT 'opt2'
UNION SELECT 'opt3'
UNION SELECT 'opt4') a
WHERE val IN (#Param)
Thoughts: easier to maintain than visibility on a table, but still two hard-coded places within the report.
Option 2: Create a dataset that selects the multi-value parameter and splits it by each value. This was my first idea, but I ran into some issues with determining how to actually select the multi-value without a syntax error. I came up with a method that creates a deliminated string in the report and than parsed that string back into rows in the dataset:
Step 1) Within the dataset properties, on the parameter tab, join the multiple values together with a JOIN expression
Step 2) Create a simple query which uses the new SQL Server 2016 function string_split. Note that your database compatibility level MUST be 130 or higher to use this function (SQL 2016+). If this isn't your scenario, there are many string split functions that you can find on Stack Overflow to achieve the same thing.
Fun problem!
H, I have a parameter 'Client' as drop down in SSRS report. My requirement is to select all the records for all the clients if i don't select any parameter value and if i select particular value in the drop down,i need to display records for the that particular client.
I am getting the list of clients as a input from query.How can i add option select all by default.
Thanks in advance
You can do this a few ways...
Check the "Allow Multiple values" on the general tab of the Parameter Properties, go into the Available values and select the dataset you are using to get the values, make sure the the column that contains the actual data to search on is what you select for the VALUE field...(with this one - make sure your query eliminates the NULLs for the Value field) then you will have a drop down with all the values and it will add Select All...
Then in the Default Values tab, you can hook to the same query and select the VALUE field again... (as long as there aren't any NULLS) You may need to do tweaking depending on your query and values...
or
You can check the "Allow Null Value" on the General tab in the Parameter Properties, then in the Default Values - select "Specify Values", then Add, and (null) pops in there automatically...
Then call a stored procedure where the parameter defaults to NULL and if you pass NULL or don't pass in a string of values, your query will return all (not sure how you'd implement this if your query is embedded in the report... I try to do all of mine in Stored Procedures..)
Add "All" to the results of the query that returns a list of clients for the drop-down and make it the default selection. Then handle it in your main stored procedure that if "All" was selected, you don't filter by clientId, and just get all clients.
I guess that's easy... I have a multi-value parameter that got the list of values from a query. I would like to select as default value the last row.
Can I achieve this using a expression? I would like to avoid creating a second query just to get the last value from the previous query...
In the default parameter expression you can't refer to the field of the dataset, so you can't write something like Last(Field!MyVar.Value, "DataSet1"), as a workaround you can order your dataset to retrive last row as first and use "Get values from a query" which choses first row, if you can't do this then replicate your dataset in the only one solution.
I am working with SSRS 2012 and I was using a multi select option on my report so when I chose the "Get Values from a query" I got all of the values as the default.
I did find a solution. In my report I needed the default name of the town to be the first one so I created another set with the name of the column and a calculated measure that said "[DimTahanot].[Tahana Name].&[אילת]" and filtered it by the same one. (Please ignore the different language). Although hard coded it was good for this report. You could create another hidden parameter for this set if you need it to be the first one by amount or any other parameters that should effect this value, using the filter as a parameter.
Hope this helps.
I have two parameters that cascade from a date parameter. The first cascading parameter is able to populate and defaults to selecting all labels (this is what I want). The second successfully populates the values but defaults to selecting none (this is what I want to fix). I have verified that both are returning their respective default values from a query - and I know the query is good for the problematic parameter because it populates with available selections successfully, it just wont default to selecting them all.
Are there any issues with having two parameters cascade from a single one? Any issues in the result set that would successfully return labels for a parameter but would not be valid for default values?
Any help would be appreciated.
Answer was posted in the comments by OP:
I was returning a NULL value which was keeping me from being able
select all in a multi-attribute parameter. I am now handling this with
a CASE statement checking for NULL.
I have reports that have multiple parameters cascading from a single one, so I don't think that's the problem.
My hunch is that something isn't right in the parameter. To troubleshoot this, set the value field and the Label field for the Available Values and the default values all to be the exact same field from the same dataset. (Use the one that was originally the Value field for the parameter.) If you "select all" do you get all the data you expect?
