I have an SSRS report. It has a Marks dropdown, and a resultset "Classresult". When I select any value from Marks dropdown, it filters my result for selected value and displays the result.
Say when I select "100" from marks dropdown, it filters my Classresult dataset and shows all results with 100 value.
But it doesnot show values which have NULL in marks field.(the resultset ClassResult contains NULL values.
Is there any way i can include NULL values ??
Currently my condition is:
Marks == Parameters!Marks.Value
Do you have the ability to wrap an IsNull() around the Class result field in your datasource?
Like IsNull(ClassResult,0) AS Classresult
This will replace nulls with a zero. Alternately you could replace the 0 with a different value of your choice.
Use the IsNothing() function to check for a NULL value in an SSRS expression. It returns TRUE if the value is NULL.
You can include NULL in the query that populates the Marks drop down. (If you put the available values in statically, then add it there...) but here is how you can do it in the query.
SELECT ValueField, LabelField
FROM MarksTable
UNION
SELECT '(NULL)', '--NULL--'
Then in the query whose results you are filtering add
ISNULL([Marks], '(NULL)') as Marks

I received this error when I am trying to run a select statement in a text box in SSRS. So, basically, I am trying to return a field which is not in the given dataset. So I have run a subquery which returns the value using the existing dataset as a container.
But I don't know how to represent that return value in the Expression field. Because the expression field returns a value which is within the dataset provided.
I have provided the SQL that I have written.
Any suggestions would be much appreciated.
My intention is to return the "CommentText" value. However, the dataset does not contain any commenttext field, but an EmpID field. So I have created the subquery below that brings up the CommentText from LaborDtlComment table and when it matches with the EmpID in the report dataset it returns the CommentText Value.
select [CommentReturnQuery].[LaborDtlComment_CommentText] as [LaborDtlComment_CommentText],
[EmpBasic].[EmpID] as [EmpBasic_EmpID]
from Erp.EmpBasic as EmpBasic
inner join (select [LaborDtlComment].[CommentText] as [LaborDtlComment_CommentText],
[LaborDtl].[EmployeeNum] as [LaborDtl_EmployeeNum]
from Erp.LaborDtlComment as LaborDtlComment
inner join Erp.LaborDtl as LaborDtl on LaborDtlComment.Company = LaborDtl.Company
and LaborDtlComment.LaborHedSeq = LaborDtl.LaborHedSeq
and LaborDtlComment.LaborDtlSeq = LaborDtl.LaborDtlSeq) as CommentReturnQuery
on EmpBasic.EmpID = CommentReturnQuery.LaborDtl_EmployeeNum
My aim is to show the CommentText value in a text field. So I will create the
text field and it will contain the SQL that I have written. Can anyone help
me in this case?
It maybe simpler to use the SSRS function lookup (single paired 1 to 1) or lookupset (multiple 1 to many).microsoft lookup reference
You will have to create the query/dataset to return CommentText from LaborDtlComment table with the EmpID
I have a sql query below:
SELECT
md.refereeInternetSearch,
md.refereeCompanyColleague,
md.refereeIndustryPeer,
md.refereeIndustryEvent,
md.refereeIndustryPublication,
md.refereeMarketingEmail,
md.refereeOther
FROM
marketing_details md
WHERE
md.id = 14588
From the 7 columns in the above select statement only one column will have a value and rest will be null. Is it possible to select just that one column value that is not null using some sort of sql statement ?
Use the coalesce() function to return the 1st non-null value from a list of parameters:
SELECT
coalesce(md.refereeInternetSearch,
md.refereeCompanyColleague,
md.refereeIndustryPeer,
md.refereeIndustryEvent,
md.refereeIndustryPublication,
md.refereeMarketingEmail,
md.refereeOther) as non_null_value
FROM
marketing_details md
WHERE
md.id = 14588
However, it will not be able to tell you which column the value came from.
UPDATE
If you really want to use sql to retrieve the name of the field that has the non null value, then you can do that with the following monstrous sql statement below. What it does it concatenates each field value from a record into a single string, where the values are separated by comma. NULL values are converted to empty string. Then using find_in_set() function it finds the position of the only non null value within the above string. Then using the elt() function it returns the name of the field from the list of field name literals based on the position returned by find_in_set().
SELECT
md.id,
coalesce(md.refereeInternetSearch,
md.refereeCompanyColleague,
md.refereeIndustryPeer,
md.refereeIndustryEvent,
md.refereeIndustryPublication,
md.refereeMarketingEmail,
md.refereeOther) as non_null_value,
elt(find_in_set(coalesce(md.refereeInternetSearch,
md.refereeCompanyColleague,
md.refereeIndustryPeer,
md.refereeIndustryEvent,
md.refereeIndustryPublication,
md.refereeMarketingEmail,
md.refereeOther),
concat(coalesce(md.refereeInternetSearch,''),',',
coalesce(md.refereeCompanyColleague,''),',',
coalesce(md.refereeIndustryPeer,''),',',
coalesce(md.refereeIndustryEvent,''),',',
coalesce(md.refereeIndustryPublication,''),',',
coalesce(md.refereeMarketingEmail,''),',',
coalesce(md.refereeOther,'')
)
),'refereeInternetSearch',

'refereeIndustryEvent',
'refereeIndustryPublication',
'refereeMarketingEmail',
'refereeOther'
) as field_name

marketing_details md
WHERE
md.id = 14588
Huh, I hope I got all the parentheses right!
I have a dataset which brings in distinct values of a column 'A' of table 'B' and these form the select values for a parameter 'Param_A'. In addition to this I have a main dataset which brings in data from table 'B' and contains the column 'A' as 'Field_A'.I do not want to alter the main dataset and hence I am using a tablix filter to filter out the result set of the main dataset. The tablix filter is supposed to be performing the below functionality :
Expression:
Fields!Field_A.value in (Parameter!Param_A.value) or Fields!Field_A.value is NUll
Boolean Operator :
"="
Value:
True
But I am unable to use the operator 'in'. It gives me an error.Could you please help me out with this?
I used the 'inStr' Operator which eliminated the possibility of using 'in' operator:
iif(InStr(Join(Parameters!Project.Value,","),Fields!project_name.value)>0,
true,false)
This helped me!
I'm creating a debtor invoicing report which has two parameters.
Parameter 1: This is a single value parameter called #booking_date. I filter the results(main dataset) by adding this into the query as a query parameter.
Eg. WHERE BookingDate = #booking_Date
Parameter 2: This parameter has two specified values - Yes or No. The parameter is called #live_run and the default value is 'No'. Basically, when this parameter has the default value of 'No', it does not limit/effect the results in any way. On the other hand, when this parameter has a value of 'Yes', it should limit the results by only displaying the bookings where the invoice has been paid off. There is a field I can use for this called Booking_Paid_off as follows - WHERE Booking_Paid_Off = 1.
I have parameter 1 in place, but I am unsure how to bring in Parameter 2 because it will be based on two conditions, do I need to use an If statement or a case statement? Do I need to create a new dataset for the second Parameter? I only want to limit the results with Parameter 2 ONLY if Parameter 2 has a value of Yes, otherwise I want the results to stay the same.
You have many options. You can switch out the Dataset entirely based on the parameter or use an IF inside the dataset to determine which query to run or simply check the parameter in your WHERE clause.
I recommend the latter.
SELECT
Field1,
Field2
FROM
Table1
WHERE
(
(#live_run = 'Yes' and Booking_Paid_Off = 1)
or (#live_run <> 'Yes')
)
We have a series of reports which return a set of values for a parameter based on the userID. This works and we're happy with the way it works.
Now we need to implement a default parameter setting. The logic being
If there is only one value in the parameters available dataset, then set that as the default.
If there is more than one value in the parameters available dataset, then leave the parameter blank.
This is what I have so far - I know I have the following issues:
-Parameters cannot read fields, therefore I need the expression to look at the dataset as a whole.
-I'm unsure what my then statement should be to allow the user to review all available values without them being selected.
=IIf(CountDistinct(Fields!storekey.Value, "UserStoreVerification")) = 1, First(Fields!storekey.Value, "UserStoreVerification")," ")
You can create a separate dataset to populate the "default values" for the parameter. In this dataset you can add logic to count the number of rows that would be returned by the other dataset that provides the parameter values. If there are greater than 1 values returned by the first query then the second dataset just returns NULL (i.e. no default values are selected).
Example
If your original dataset for parameter values (e.g. "dsParamProduct") used a query like this:
SELECT ProductNumber
FROM dbo.Product
WHERE Available = 'Yes'
Then the dataset query for the default values (e.g. "dsParamProductDefault") could be something like this:
DECLARE #ValueCount INT
SELECT #ValueCount = COUNT(*)
FROM
(
SELECT ProductNumber
FROM dbo.Product
WHERE Available = 'Yes'
) vals
IF #ValueCount = 1
SELECT ProductNumber
FROM dbo.Product
WHERE Available = 'Yes'
ELSE
SELECT NULL
Supplying "NULL" as the default value when there is more than one value will mean none of the available values are selected and therefore the user will have to manually select them (assuming that NULL isn't a valid value for your parameter - if it is then make sure the default query will return something else that is definitely not valid). If there is only one possible value then the default value query just returns the same result as the parameter values dataset, which means that the parameter value will be selected.
Set up another parameter that is dependent on the first, same type but slightly different name, and do your code at bottom with one suggested change:. Change " " at the end before the parenthese end to be 'NOTHING' instead. I believe this is interpreted by SQL as NULL which is what you want.
Now you should be getting population of the parameter so I would debug and check it by just dragging and dropping it to the design surface and it should be black if you have more than one default value. You can optionally make this parameter 'hidden' once you can confirm it works.
Now you trick your main dataset with a nifty predicate (or else use some other logic if it suits you better)
Where value = isnull(#DependentParam, value)
Basically this is stating "if the parameter is not null use it, else equate the clause to be everything as it will assume value = value".
