RUNNING_SUM
RUNNING_SUM(SUM([Hours Spent]))Syntax
RUNNING_SUM({aggregation method}(numerical expression))
A running sum is the summation of a sequence of numbers which is updated each time a new number is added to the sequence, by adding the value of the new number to the previous running value.
aggregation method: Any aggregation function SUM, MAX, COUNT and etc applied to numeric expression.
numerical expression: Basic arithmetic calculation created using the math operators +, -, *, /, numerical data fields and constants.
For example we have the data set below after applying aggregation COUNT([ID]) to income record set
| # | COUNT([ID]) |
|---|---|
| 1 | 5 |
| 2 | 35 |
| 3 | 25 |
Applying RUNNING_SUM(COUNT([ID])) will give the table below
| # | RUNNING_SUM(COUNT([ID])) |
|---|---|
| 1 | 5 |
| 2 | 5 + 35 = 40 |
| 3 | 40 + 25 = 65 |
