I cannot make the my expression NOT count a NULL value in my SSRS matrix.
In my SSRS matrix, I have 2 columns one for AppraisalCompany and a count under the SubmittedDate column. In my report this what is happening:
Per Derrick's suggestion here is the change I made in the ColumnGroup properties for the SubmittedDate:
Here is my expression change in the ColumnGroup properties:
Unfortunately I got this error:
I'm suspicious of your Dataset, I'm not entirely sure how you're getting a null value to return 1 in the COUNT. I have been unable to reproduce your results.
Dataset Query
SELECT 'Drive In' AS AppraisalCompany, NULL AS SubmittedDate
UNION
SELECT 'Photo App - English', 'Dec-18'
Next I created a Row Group on AppraisalCompany and a Column Group on SubmittedDate.
I filtered the column group to remove the null grouping, using the expression =IsNothing(Fields!SubmittedDate.Value), operator <>, and Value true.
In the textbox in the matrix I used [Count(SubmittedDate)].
OUTUT
Appraisal Company | Dec-18
-------------------------------
Drive In | 0
Photo App - English | 1
By a Decimal (Number) datatype Nothing and 0 are the same. You can test this.
Put a tablix into your report with year from 2017 to 2019. Then put the year in a column of the tablix as a number format, then write the following expression in the detail textbox:
=CDec(IIF(CDec(Fields!Year.Value) = 2017, 0, Nothing))
After executing your report you will notice that every value in the year column is 0.
The same goes for the check. Both of these expressions will always return Yes. I basically check for 0 and the second one for for Nothing:
=IIF(CDec(IIF(CDec(Fields!Jahr.Value) = 2017, 0, Nothing)) = 0, "Yes", "No")
=IIF(CDec(IIF(CDec(Fields!Jahr.Value) = 2017, 0, Nothing)) = Nothing, "Yes", "No")
But remember your textbox/column has the be a number format.
So if you want to return Nothing and you display it in a number format textbox, it will show you a 0.
With this in mind it will make sense that a Count() returns the value 1 for 0 AND Nothing. So basically this will do the trick:
'Cont
=Sum(IIF(Fields!YourValue.Value = Nothing, 0, 1))
I have the following table row group:
Name|Percent|
val1|67% |
val2|33% |
I want to know if is possible to get the percent of the val1 in a textbox? Thanks for the help.
Since your percentage is calculated with the rowcount of val1 to the total rows you can use the expression below:
= SUM(Iif(Fields!Name.Value = "val1",1,0))/COUNTROWS("AllReport")
The sum actually counts the rows with value equal to "val1"
Apologies for the long post.
I have an SSRS 2012 report looking at 2 datasets, Dataset1 and Dataset2.
Dataset2 may return 0, 1 or 2 records, so I'm using LookupSet to do this. From the records returned, I need to display several fields.
The report is grouped by Main_ID. In the footer of Main_ID, I am counting the number of returned records from Dataset2.
=LookupSet(Fields!MainID.Value, Fields!MainID.Value, Fields!Record_Name.Value, "Dataset2").Length
This works fine, I'm getting 0, 1 or 2 as appropriate.
In Dataset2 the field:
HasIP
will be used to determine which record in the array I display (as I need to test a field value in Dataset2).
I'm trying to use a switch statement to use the length of the LookupSet array to return the correct fields.
If there are no records (eg length of array = 0) then return the
number 2
If there is 1 record (eg length of array = 1), then return
Record_Name
If there are 2 records (eg length of array = 2), then
check the field HasIP.
If HasIP = YesYes, then return the Record_Name of that matching entry
If HasIP = YesNo, then return the Record_Name of that matching entry.
If all else fails, return the number 2
This is what I'm up to at the moment.
=Switch(
'if no returns returned, display the numeral 2
LookupSet(Fields!Main_ID.Value, Fields!Main_ID.Value, Fields!Record_Name.Value, "Dataset2").Length=0, 2,
'if one return returned, then display Record Name
LookupSet(Fields!Main_ID.Value, Fields!Main_ID.Value, Fields!Record_Name.Value, "Dataset2").Length=1,
LookUp(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!Record_Name.Value,"Dataset2"),
'if two records returned, check the HasIP field. If HasIP = YesYes, then use this combination first.
LookupSet(Fields!Main_ID.Value, Fields!Main_ID.Value, Fields!Record_Name.Value, "Dataset2").Length=2 AND
LookUpSet(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!HasIP.Value,"Dataset2")(0)="YesYes",
LookUpSet(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!Record_Name.Value,"Dataset2")(0),
LookupSet(Fields!Main_ID.Value, Fields!Main_ID.Value, Fields!Record_Name.Value, "Dataset2").Length=2 AND
LookUpSet(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!HasIP.Value,"Dataset2")(1)="YesYes",
LookUpSet(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!Record_Name.Value,"Dataset2")(1),
'if two records returned, check the HasIP field. If HasIP = YesNo, then use this combination second.
LookupSet(Fields!Main_ID.Value, Fields!Main_ID.Value, Fields!Record_Name.Value, "Dataset2").Length=2 AND
LookUpSet(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!HasIP.Value,"Dataset2")(0)="YesNo",
LookUpSet(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!Record_Name.Value,"Dataset2")(0),
LookupSet(Fields!Main_ID.Value, Fields!Main_ID.Value, Fields!Record_Name.Value, "Dataset2").Length=2 AND
LookUpSet(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!HasIP.Value,"Dataset2")(1)="YesNo",
LookUpSet(Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!Record_Name.Value,"Dataset2")(1),
'If all else fails, display the number 2
True, 2)
I'm getting the correct one returned for 2 records, but getting #ERROR for zero and 1 records. If I break the formula down to their individual parts:
=SWITCH(
LookupSet(Fields!MainID.Value, Fields!MainID.Value, Fields!Record_Name.Value, "Dataset2").Length=0,
2)
This works. The number 2 is displayed in my report where the are no entries in Dataset2 (the field is blank for any other combination).
If I use:
=SWITCH(LookupSet(Fields!MainID.Value, Fields!MainID.Value, Fields!Record_Name.Value, "Dataset2").Length=1, LookUp(Fields!MainID.Value,Fields!MainID.Value,Fields!Record_Name.Value,"Dataset2"))
This works fine for when I have 1 record returned from Dataset2 (the field is blank for any other combination).
No matter what I tried with the third part (handling the 2 records), I'm getting issues. I can get the correct Record Name returned, but I'm getting #ERROR for 0 or 1 records.
I've tried nesting the third part in IIF statements, flipping it round to look at the length first, etc, but no success.
I cannot edit the underlying query of either dataset.
Any guidance much appreciated.

See:
SSRS 2012. Replicate grouping results in report in Query Designer
Essentially it was adding a numeric value to HasIP and also add in the Primary key of the second dataset.
Then sort the LookupSet array to get the value you want.
In the expression, you can use this to assign a default value, even when there are not results returned by the LookupSet:
=iif(
LookupSet(
Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!Main_ID.Value,"Dataset2"
).Length>0,
Mid(
Split(
Join(
Code.JoinSorted(
LookupSet(
Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!Q12b.Value,"Dataset2")
)
,";")
,";").GetValue(0)
, 'start point of mid
InStr(
Join(
Code.JoinSorted(
LookupSet(
Fields!Main_ID.Value,Fields!Main_ID.Value,Fields!Q12b.Value,"Dataset2"
)
)
,";")
,"$")
+1,

"2"
)
I have a simple COUNTIF task in Excel that is proving rather difficult to replicate in Tableau...
This is the data:
ID Metric Scope DynamicCalc
1 A1 TRUE X
1 B1 FALSE X
2 B1 TRUE X
2 A1 FALSE X
2 C1 FALSE X
The column 'DynamicCalc' should have the following values when Metric=A1 is selected: TRUE,TRUE,FALSE,FALSE,FALSE but if say B1 is selected it would be FALSE,FALSE,TRUE,TRUE,TRUE... so basically I want to assign a value of TRUE to the DynamicColumn if there is at least one TRUE in the Scope column to all rows for that ID.
The LOD Expression can be used to retrieve your desired result
try using a calculated field like below :
{FIXED [ID],[Metric]:MAX(if [Scope]='TRUE' then 'True' else 'False' end)}
When the Selection is B1 :
I know this is late, but as SO community (bot) has made it active again, I propose a slightly different approach. The selection should be through parameter.
After making parameter on Metric field, create a calculated field say Dynamic calc like this
{FIXED ID : MAX({FIXED ID, [Metric]: MAX(If [Metric] = [Metric Parameter] THEN [Scope] END)})}
Add this field and your desired view is complete. See GIF below
Picture a table with fields (Id, Valid, Value)
Valid = boolean
Value = number from 0 to 100
What I want is a report that counts the number of records where (valid = 0), and then gives me the total number of cases where (value < 70) and the number of cases where (value >= 70).
The problem is that the "value" field could be empty on some of the records and I only want the records where the value field is not empty.
I know that the second value (value>=70) is going to be calculated, but the problem is that I can't simply do (total number of records - number of records where value < 70), because there's the problem with the records where "value" is null...
And then I want to create graphic with these values, to see the percentage of records below and above 70.
"The problem is that the "value" field could be empty on some of the records and I only want the records where the value field is not empty."
Use a WHERE clause to exclude rows whose "value" field is Null.
Here is sample data for tblMetraton.
Id Valid Valu
1 -1 2
2 0 4
3 -1 6
4 0
5 0 90
I used Valu for the field name because Value is a reserved word.
You can use the Count() function in a query and take advantage of the fact it only counts non-Null values. So use Count() with an IIf() expression which returns a non-Null value (I used 1) for the condition you want to match and Null otherwise.
SELECT
Count(IIf(Valid=0,1,Null)) AS valid_false,
Count(IIf(Valu<70,1,Null)) AS below_70,
Count(IIf([Valu]>=70,1,Null)) AS at_least70
FROM tblMetraton AS m
WHERE (((m.[Valu]) Is Not Null));
Based on my sample data in tblMetraton, that query gives me this result set.
valid_false below_70 at_least70
2 3 1
