Question

In SSRS 2005 I am reporting on all available posts by regional office, listed by region,office,vacancyID.
I then display a total per office on how many people started in a particular vacancyID by doing a Count(VacancyStartID).
In the same group row with the Count(VacancyStartID) I need to display SUM(VacancyID).
However at present this does not give the correct SUM, because some vacancies have multiple VacancyStartID’s and hence the vacancyID is listed few times, like so:

office vacancyID Number_of_vacancies       VacancyStartID (person who started a job)

 1         1              2                4567

 1         1              2                5678


Totals:                   4 (needs to be 2)    2  

P.S. Note:These questions are not applicable in this instance:
How can I remove duplicate rows?

How do I remove "duplicate" rows from a view?

Using multiple COUNTs and SUMs in a single SQL statement

Answer 1

If it’s in the Underlying SQL Server call…

You can do ...SUM(DISTINCT VacancyID)... like you can COUNT (DISTINCT ..)

Edit:

SELECT
    col1, col2, SUM(DISTINCT Number_of_vacancies)  as foo, COUNT (VacancyStartID) as bar
FROM
    MyView
...

If it’s in the table or for a cell in the report, then there is no equivalent in the SSRS SUM function.
