How to Round Numbers in SQL

Показать описание
Computers thrive on never-ending decimal places, but humans often find them overwhelming. That's precisely why mastering the ROUND function in SQL is crucial when dealing with numeric operations.

The ROUND function can envelop any calculation or number within a SQL statement, rounding it to a specified number of decimal places, making your data more digestible and presentation-ready.

👨‍🏫 Examples:

ROUND(SUM(Sales), 2) AS Sales: This rounds the sum of your sales to two decimal places.

ROUND(Sales - Profit, 0) AS Cost: Subtracts profit from sales, rounds the result to no decimal places, and labels the output as "Cost."

ROUND(Salary / Age, -3) / 1000 AS Salary_Calc: Divides salary by age and rounds it to the nearest thousand.

In the video below, I demonstrate how to utilize the ROUND function with column calculations, aggregations, and percentages to refine your data analytics process.
