Name
total() — Return the numerical total
Common Usage
total( number )Description
The total() aggregate computes the sum or total of
all the non-NULL
values. Any non-NULL number
that is not an integer will be interpreted as a
floating-point value. The number
total() aggregate is specific to SQLite.
Unlike sum(), the total() aggregate will
always return a floating-point value.
Even if all
expressions are NULL, number
total() will still return a 0.0.
