How to sum the values of multiple fields in a hive?

To calculate the sum of values in multiple fields of a Hive table, you can use the SELECT statement and the SUM function. Assuming we have a table named example with fields A and B, we can use the following query to sum up the values of these two fields:

SELECT SUM(A), SUM(B) FROM example;

This will return the total sum of fields A and B. You can also sum multiple fields and then aggregate the results into one total sum.

SELECT SUM(A + B) AS total_sum FROM example;

This will return the total sum of values for Field A and Field B. You can also use a WHERE clause to filter the data as needed.
