0 2

Remember not all database systems support ORDER BY in the OVER clause of a window aggregate function.

SQL Server didn't support it until the latest version SQL Server 2012.

So you need to use PARTITION BY.

SELECT Id, StudentName, StudentGender, StudentAge,
SUM (StudentAge) OVER (PARTITION BY ID) AS RunningAgeTotal
FROM Students
