To calculate the percentage in a SQL statement, use the formula:
For example, if you have a table sales
with columns amount
and total_sales
, you can calculate the percentage of sales for each record:
This query divides the amount
by total_sales
, multiplies the result by 100, and returns the sales percentage. Make sure total_sales
is not zero to avoid division errors. You can also round the result using the ROUND()
function for better presentation.
