How to Select Data from a Date Range Between Two Dates

In a database table holding sales data, it may be necessary to retrieve records for a specific date range. This article explores how to achieve this using a SQL query.

Consider a table named "Product_Sales" with columns including "Product_ID," "Sold_by," "Qty," "From_date," and "To_date." Each row represents a sales transaction with a start date ("From_date") and an end date ("To_date").

To select sales data within a specified date range, the query must filter the records based on the "From_date" and "To_date" values. The goal is to select records where the date range intersects with the given date range.

There are two approaches to this:

Approach 1: Excluding Incorrect Options

This method eliminates records with date ranges that do not overlap with the given range. The following SQL query achieves this:

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

In this query, "@RangeFrom" and "@RangeTill" represent the start and end dates of the target date range, respectively. This query retrieves all records whose "From_date" is less than or equal to "@RangeTill" and whose "To_date" is greater than or equal to "@RangeFrom."
