How Can I Efficiently Generate a Range of Dates in MySQL?

Efficient Generation of Dates in a Range

In MySQL, generating a series of dates within a specified range is a common task. This is often essential for report generation, ensuring that data is available for every date, regardless of activity.

Despite the availability of techniques like creating tables or using temporary tables, these approaches can be suboptimal. This article explores a solution that addresses the limitations of temporary tables and variable setting restrictions, offering an efficient way to generate a list of dates within a range.

The solution utilizes a UNION query to combine multiple subqueries, each representing a single digit position. By multiplying the results of these subqueries by appropriate powers of 10 and combining them, a generated date is produced.

To use this solution, simply replace the dates in the provided query with your desired start and end dates. The result will be a table containing a series of dates within the specified range.

This approach provides a versatile and efficient method for generating dates in MySQL, suitable for various scenarios, including when temporary table creation or variable setting is prohibited.
