3.6 Aggregate functions
In most cases group reports need to display some summary information (such as: ???total of a group???, ???number of group elements??? etc). FastReport provides aggregate functions for calculating aggregate values over some data span. The aggregate functions are:
SUM returns the total of an expression MIN returns the minimal value of an expression MAX returns the maximal value of an expression AVG returns the average value of an expression COUNT returns the number of lines (rows) in the data span
The syntax of all aggregate functions (except COUNT) is similar to that of the SUM function:
SUM(expression, band, flags) SUM(expression, band) SUM(expression)
The parameters are:
expression the expression to be calculated
band the name of the data band within which the calculation is performed
flags a bit field, with values
1 : include invisible bands in calculation
2 : accumulate the aggregate as a running total (do not reset the aggregate when the current data span resets)
3 : (both of the two previous options)
An expression is the only mandatory parameter, the other two are optional. Nevertheless, to avoid making mistakes it is recommended that band parameters are always given.
