sql server - Conditionally count based on other field data in SSRS Report -


i working ssrs report, have field named details , count of other field serialnumber.

so in short want total count of serialnumber has no details.

i tried below not working. give total count count without considering blank details

=cstr(count(iif(not(isnothing(fields!details.value)),fields!serialnumber.value,0)))

how can achieve expression? please help.

issue data. in dataset fetching rows based on isnull() below

select case              when 'y'='y' isnull(code ,'') + '  ' + isnull(description ,'')             else case                        when isnull(code ,'')='' isnull(refcharge ,'')                            +'  '+isnull(refdescription ,'')                       else isnull(code ,'')+'  '+isnull(description ,'')                  end        end               details

so showing (3 blank spaces) , expression was.

=count(iif(fields!details.value<>"",fields!number.value,nothing))

finally tried below, it's working fine now.

=count(iif(trim(fields!details.value)<>"",fields!number.value,nothing))

note: so have noted whenever need check such kind of conditions must have use trim()
