SQL ROUND: Keep Decimals in Averages

In SQL, you can utilize the ROUND function to retain decimal places. For instance, if you want to calculate the average of a field and keep two decimal places, you can do the following:

SELECT ROUND(AVG(column_name), 2) AS avg_value
FROM table_name;

In the query above, the AVG function is used to calculate the average of a field, and then the ROUND function is used to keep the result to two decimal places. You can adjust the number in the ROUND function to keep a different number of decimal places as needed.
