124 views

To get data grouped by month in SQL, you can use the `MONTH` function along with the `GROUP BY` clause. For example, if you have a table `sales` with a date column `sale_date`, you can write a query like this: `SELECT MONTH(sale_date) AS month, COUNT(*) FROM sales GROUP BY MONTH(sale_date);`. This will return a count of sales grouped by month. Adjust the query according to your specific database management system (DBMS) syntax and date field.
