Efficient Date Range Filtering in MySQL with Proper Indexing

Optimize Query with Date Range Filtering using Index

Write a MySQL query to retrieve all orders placed between '2025-01-01' and '2025-02-01' from the Orders table, ensuring the query leverages an index on the OrderDate column.

Solution:

-- Retrieve orders within a specific date range.
SELECT * FROM Orders
WHERE OrderDate BETWEEN '2025-01-01' AND '2025-02-01';

Explanation:

• Purpose of the Query:
• To fetch orders within a defined date range efficiently.
• Demonstrates how a WHERE clause can benefit from an index on the OrderDate column.
• Key Components:
• SELECT * FROM Orders : Retrieves all columns from the Orders table.
• WHERE OrderDate BETWEEN '2025-01-01' AND '2025-02-01' : Filters the records by date range.
• Real-World Application:
• Useful in reporting and analytics where date-based filtering is common.

Notes:

• Ensure the OrderDate column is indexed to improve query performance.
• Date range queries can see significant performance gains with proper indexing.
