To calculate the total revenue within 3 months in PostgreSQL, you will need to sum up the revenue for each month and then add the totals together. You can achieve this by writing a SQL query like the following:

1
2
3
4
5
6
7
SELECT 
    SUM(revenue) as total_revenue
FROM 
    your_table_name
WHERE 
    date_column >= DATE_TRUNC('MONTH', CURRENT_DATE) - INTERVAL '3 months'
    AND date_column <= DATE_TRUNC('MONTH', CURRENT_DATE)


In this query:

  1. Replace your_table_name with the name of the table where your revenue data is stored.
  2. Replace date_column with the column that contains the date of the revenue transactions.
  3. This query will calculate the total revenue for the last 3 months.


After running this query, you will get the total revenue generated within the last 3 months from your specified table.
