Why are My MySQL Date Range Queries Returning No Results?

Troubleshooting MySQL date range query issues

Question:

When using the BETWEEN operator to query a date range in a MySQL table, the query result is empty.

<code class="language-sql">SELECT * FROM `objects` 
WHERE (date_field BETWEEN '2010-09-29 10:15:55' AND '2010-01-30 14:15:55')</code>

Solution:

On closer inspection, the second date in the range ('2010-01-30 14:15:55') is before the first date ('2010-09-29 10:15:55'). This means that the query is requesting records between dates that are later than another date.

To correct this problem, reverse the order of the dates in the BETWEEN operator:

<code class="language-sql">SELECT *
FROM `objects`
WHERE (date_field BETWEEN '2010-01-30 14:15:55' AND '2010-09-29 10:15:55')</code>

After making this correction, the query will now search for records with a date_field column value within the valid date range of '2010-01-30 14:15:55' and '2010-09-29 10:15:55'.
