How to Generate Date Ranges in MySQL Using Date Arithmetic and Subqueries?

Use MySQL date operations and subqueries to generate date ranges

In SQL, retrieving a list of dates within a specified range can be achieved by using a combination of date operations and subqueries. Here's how to accomplish this:

In order to generate a list of dates between two dates, we can use the subquery method. A nested set of subqueries, each generating a sequence of numbers (from 0 to 9) that are combined by addition to form the desired date value.

The following query demonstrates this technique:

select * from
(select adddate('1970-01-01',t4.i*10000 + t3.i*1000 + t2.i*100 + t1.i*10 + t0.i) selected_date from
 (select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
 (select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
 (select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
 (select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
 (select 0 i union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4) v
where selected_date between '2012-02-10' and '2012-02-15'

This query will generate a list of dates from '2012-02-10' to '2012-02-15' (inclusive). The results are as follows:

<code>date
----------
2012-02-10
2012-02-11
2012-02-12
2012-02-13
2012-02-14
2012-02-15</code>

This method allows generating date ranges spanning nearly 300 years in the future or past.
