Name

total() — Return the numerical total

Common Usage

total( number )

Description

The total() aggregate computes the sum or total of all the non-NULL number values. Any non-NULL number that is not an integer will be interpreted as a floating-point value. The total() aggregate is specific to SQLite.

Unlike sum(), the total() aggregate will always return a floating-point value. Even if all number expressions are NULL, total() will still return a 0.0.
