I use microsoft sql server report builder.
I have a big sql query for the Presentation of my Report. i want to assign the output of one of the Columns to a textbox. the txbox should be displayed the first value of the table which is not zero.
I tried that First(Fields!name.Value, "V_Tabelle") .but if the first value is null, the textbox remains empty
I tried that IIf(IsNothing(Fields!name.Value), "null", Fields!name.Value) , but i am receiving an error. field references outside a data area must be included in aggregate functions that specify a dataset area.
First(Fields!name.Value, "V_Tabelle")
IIf(IsNothing(Fields!name.Value), "null", Fields!name.Value)
The value expression for the text field "Status6" refers directly to the field "name" without specifying a dataset aggregate. If the report contains multiple datasets, field references outside a data area must be included in aggregate functions that specify a dataset area.
This way it checks if the first value is null, is this the case the text Empty will be displayed.
=IIF(First(Fields!YourField.Value, "DataSet1") = Nothing,
"Empty",
First(Fields!YourField.Value, "DataSet1")
)

I need to run the report, without selecting anything, with parameter field blank, and be able to view all the data.
the problem is that it necessarily asks me to enter a value (all or multi values).
Who can help me?
If you make sure that you do the following...
Set the parameter to "Allow blank value" and/or "Allow null value" depending on what datatype it is.
Set the default value to Blank (="") if applicable
If you have a list of available values set, make sure the default value is included.
The following example uses sample data from sample database and contains just a list of company names and their ID's.
The main dataset query filters the data based on 2 parameters (one is text the other id numeric to show different scenarios)
This is the dataset query
SELECT CustomerID, CompanyName
FROM [AdventureWorksLT2019].[SalesLT].[Customer2]
WHERE CompanyName LIKE '%' + #pSearch + '%'
and CustomerID > ISNULL(#pID, 0)
ORDER by CompanyName
The report design looks like this with 2 parameters defined
The first parameter is text and has "Allow blanks values" checked, the Default value is set to an expression =""
The second parameter is an integer, This time we have set "Allow null value" on but we have not set a default value.
Note: Neither parameter has any available values set...
When the report is run I get the following results without pressing anything.
Only if I manually set any of the parameters do I need to press View Report, but when the report first runs, there is no need to click anything.
If the above does not help, then show how the parameter(s) are setup up, what types they are, what the available values are and what the default values are.
I am passing a unique ID as parameter in SSRS report. In the source table, unique id does not contain dashed. However, the user may insert Unique ID including dashes "-" and in some cases without dashes. Is there a way that we could remove dashes from the parameter.
For example, unique id 3120-20268-8 is stored in table as 3120202688. How I could retrieve if user pass multiple values with or without dashes in the SSRS Report.
When is used below query, it gives record against single value only. However, gives error when more than one values are provided.
select * from Table
where Unique_ID in (REPLACE(#Unique_ID,'-',''))
For more than 1 values, it gives errors mentioned below:
The replace function requires 3 argument(s).
Query execution failed for dataset 'ATL_List'.
Thanks
One of the simplest mechanisms for this is to create an expression based parameter to hold the sanitised input. This parameter would be hidden so the user is not aware of it, but the rest of the usage of the parameter is the same.
NOTE: You could do something similar with a query based default value, but this case is easier to do via a simple expression
Single Value Parameter
Create a new parameter:
set it to hidden
Set the default value expression:
=Str(Parameters!inputID.Value).Replace("-","")
Multi-Value Parameter
This is only slightly trickier, in the expression we can join the selected values together into a CSV string, then process that value and then split it back:
Set the parameter to multi-value, but still hidden:
Set the default value expression:
=Join(Parameters!inputID.Value,",").Replace("-","").Split(",")
Without going to detailed, if we made the sanitised parameter temporarily visible, just to demonstrate the conversion, it should look like this:
The parameter MUST be hidden!
NOTE: DO NOT make your sanitised parameter visible as in the above screenshot in your deployed report! Doing so will mean that it will not pickup changes made to the input value after it has rendered the first time.
remember that we have exploited the default value, we haven't arbitrarily defined en expression to always execute.
The output when the parameter is hidden is calculated when the report is rendered, it's just harder to visualise the behavior in this static post:
In your DataSet query you would just use the sanitised parameter:
SELECT * FROM Table WHERE Unique_ID IN (#sanitisedMultiValue)
You should be able to use the replace function in your report to format the parameter value after it has been entered, something like the below
replace(Fields!Paramater.Value,"-","")=FieldinYourTable
I'm creating a single SSRS report that is composed of data drawn from different Datasets. What I'm wanting to do is have a drop down menu where the user selects the dataset they wish and have the appropriate table turn on and show them the dataset information.
Right now I'm testing with two tables and in there Visibility property I have the following expression:
=IIf(Parameters!AppSelection.Value = "STRAW", false, true)
The other table has the exact same line in the same place but with a different value between the quotes.
With my parameter, I created a new one and called it AppSelection and gave it 2 Available Values that matched the words between the quotes in my above expression. The data type for my parameter is Text and the Value of the each Available Value is left at null.
When I preview my report and select the different values in the parameter, nothing happens. What is it I'm doing wrong?
Change the null in the available values to your text, ie STRAW.
You may find that the tables show the other way round from expected, switch the true and false.
I'm trying to make a MS Access report, where I use a text box to display a field value, then have another text box indicating if the first value is higher or lower than an entry in a separate table.
The report has a record source of "Table 1", and a textbox named "txt_Value1" which displays the number in Field: "Value1". I have a second table, "Customer_Criteria" which has a field "PassValue" that I want to compare against. My expression builder statement is:
IIf([txt_Value1]<(DLookUp("[PassValue]","[Customer_Criteria]","[Customer] = 'ABC'")),"TRUE","FALSE")
This statement always returns false, regardless of what the correct logical result is.
I've tested it, writing:
IIf(1<(DLookUp("[PassValue]","[Customer_Criteria]","[Customer] = 'ABC'")),"TRUE","FALSE")
And I get the correct results. Also, if I write:
IIf([txt_Value1]< 1,"TRUE","FALSE")
I get the correct results. What am I missing to compare the textbox value vs. the Dlookup?
As I understand, both fields are numeric. Access may consider those fields as text, so for correct comparing use type conversion.
Try this:
IIf(CLng(Nz([txt_Value1],0))< _
CLng(Nz(DLookUp("[PassValue]","[Customer_Criteria]","[Customer] = 'ABC'"),0)), _
"TRUE","FALSE")
Nz required if fields may contain NULL values, in this case type conversion function will return error.
In my report, I have an expression which is used to pass a parameter to a child report parameter which is set to allow null values. The expression is :
=IIf(Parameters!Lead.Value = "False",Nothing,Fields!Paid.Value)
The above expression returns values only when Fields!Paid.Value is not blank. Therefore when Fields!Paid.Value is blank I get an error
"the value provided for the report parameter is not valid"
How do I modify my expression to parse these two conflicting issues?
What I want is to be able to return values when the Fields!Paid.Value is blank or when it is not. So at all time when the expression runs corresponding values are returned without the error stated above.
Thanks for helping out.
The first thing you do, wherever you have used the "Paid" parameter, set it to allow null value. Allow null only not blank.
The second thing about the expression, use something like this,
=IIF(Parameters!Lead.Value "FALSE", Nothing, IIF(IsNothing(Fields!Paid.Value),0,Fields!Paid.Value)
