SQLite SUM Function
The SUM function in SQLite is an Aggregate Function used to find the sum of all non-NULL values in a column. The output of the SUM function is mostly an integer if all the non-null values present in that column are integers. If the values are mixed (Integer and Non-Integers) then the result will be in float. If the SUM function is used on a column that consists of only NULL values or has only one row that is NULL / Empty, it will not throw any error, but it will return NULL as output, not 0.
SQLite SUM() Function
SQLite is an embedded database that doesn’t use a database like Oracle in the background to operate. It is written in C language and is used by developers who embed a lightweight database over the existing application, browser, or embedded systems. The main features of SQLite are that it is a tiny, quick, self-contained, reliable, full-featured SQL database engine.
In this article, we will understand the SUM Function in SQLite in detail along with some practical examples and so on.
