Hive SUM Function: Complete Guide

In Hive, you can use the SUM function to calculate the sum of values in a specific column. Here is how to use it:

SELECT SUM(column_name) FROM table_name;

“Where column_name is the name of the column to perform the sum operation on, and table_name is the name of the table containing that column. After executing the above statement, it will return the total sum of all values in that column.”

For example, let’s say there is a table named “sales” with a column called “amount,” and we want to calculate the sum of the values in the “amount” column. We can use the following statement:

SELECT SUM(amount) FROM sales;

This will return the sum of all values in the amount column.
