    Description copied from interface: SQLFunction
    
    A function can make calculation on several records before returning a result.
    Example of such function : sum, count, max, min ...
    The final result of the aggregation is obtained by calling SQLFunction.getResult()
    
    Specified by:
    
    aggregateResults in interface SQLFunction
    
    Overrides:
    
    aggregateResults in class SQLFunctionAbstract
    
    Returns:
    
    true if function aggregate results
