How to Group Sales by Region and Filter with HAVING?

SELECT region, SUM(sales) AS total_sales FROM sales_data GROUP BY region HAVING total_sales > threshold_value;

This SQL query groups sales data by region and filters to show only those regions with total sales exceeding a specified threshold.

1. SELECT the region and the sum of sales as total_sales.
2. FROM the sales_data table where the sales information is stored.
3. GROUP BY the region to aggregate sales data for each region.
4. HAVING filters the grouped results to include only regions with total_sales greater than a specified threshold.

• Regions with zero sales will not appear in the results.
• If all regions have total sales below the threshold, the result will be empty.
• Using a threshold that is negative will return all regions with sales.
