SSRS - Why isn't my SUM() working correctly? - sql

Question

I followed a guide on techonthenet where it says that for a SUM query you need to put the Sum(expr) in the SELECT statement and then GROUP BY every other field you are selecting (psuedo-code; correct me if I'm wrong). Below is my attempt. Why am I getting the error
"An error occurred while executing the query. Incorrect syntax near '('. Error:102; Line 9"
The end result of all this will be a Report, not just a query. In the report, all of the fields below will be shown with the exception that the [Difference] field will be totaled at the bottom. I get the feeling that instead of trying to sum this in the query I should be trying to sum in the report...
EDIT - I removed the [ALL] but now I get the error "Cannot use an aggregate or a subquery in an expression used for the group by list of a GROUP BY clause." It also says that this error is on line 29. I will mark it below.

Answer 1

The error is due to this line:
Sum([ALL] (Dateadd("n",DateDiff("n", MIN(RESSCHD000.STARTDATE),MAX(RESSCHD000.ENDDATE)),'00:00:00'))) AS [SumOfDifference]
The sum is looking for a field (or formula of some sort) to SUM up. You have a field name followed by a formula. I am guessing you want the sum of the difference in seconds based on the FIELD name (SumOfDifference).
I think you just need to remove the [ALL].
SUM(DATEADD("n",DATEDIFF("n", MIN(RESSCHD000.STARTDATE), MAX(RESSCHD000.ENDDATE)),'00:00:00')) AS [SumOfDifference]
