Hi

I am looking for a function which are able to add values from a table as records are fetched.

Something like this:

Value Calculated value 

1 1

2 3

3 6

4 10

5 15

The calculated value is just the sum of all previous values of VALUE.

Whats the name of such function in english and Firebird?

Does such a function even exist in Firebird 2.5?

Regards

Michael
