How to Select Sales Data Within a Specific Date Range in SQL?

Selecting Data from a Date Range Between Two Dates

In your database, you have a table named Product_Sales with the following columns:

• Product_ID
• Sold_by
• Qty
• From_date
• To_date

Your goal is to select sales data that falls within a specific date range. For example, you might want to retrieve data from January 3, 2013, to January 9, 2013.

To achieve this, you can utilize the following query:

SELECT * FROM Product_sales
WHERE NOT (From_date > @RangeTill OR To_date < @RangeFrom)

where @RangeFrom and @RangeTill represent the start and end dates of the desired range, respectively.

How the Query Works

This query employs the "interval intersection" concept. It identifies sales where the date range does not intersect with the provided range. The criteria for such non-intersections are as follows:

1. The start date of the sale occurs after the end of the provided range (From_date > @RangeTill).
2. The end date of the sale occurs before the start of the provided range (To_date < @RangeFrom).

In other words, it eliminates sales that fall outside the specified range based on the aforementioned conditions.
