为SELECT…BETWEEN查询创建正确的日期格式

Question

I have 2 variables which make up a date range which then needs to be searched in a MySQL database.

These are in the format 'Apr, 2011' and 'Mar, 2012' etc.

My SELECT...BETWEEN query requires '2011-04-01' and '2012-03-31', so whats the best way to provide this...

Convert the dates in PHP first?

Or is there a way to write the query to search using the original format? I tried with date_format (date, '%b, %Y') but the query found nothing.

Answer 1

Try this:

SELECT * FROM tablename 
WHERE dateCol BETWEEN DATE_ADD(DATE(STR_TO_DATE('Apr, 2011', '%b, %Y')), INTERVAL 1 DAY) AND LAST_DAY(STR_TO_DATE('Mar, 2012', '%b, %Y'));
