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
