@Mohamed Which version exactly do you use ? STR_TO_DATE should work on 3.23/4.0/4.1 according to the manual – http://dev.mysql.com/doc/refman/4.1/en/date-and-time-functions.html#function_str-to-date

Thanks for sharing.
Just a note, you can also sort in this way by "sort by"

Example
SELECT * FROM `TABLE` ORDER BY STR_TO_DATE(date, '%d.%m.%Y') DESC

Thanks man!

I have a table (eventos) with 3 columns for store date:

one column for dia (day)
one column for mes (mont)
one column for ano (year)

I use this line:

SELECT * FROM (SELECT *, STR_TO_DATE( CONCAT(ano, ‘-’, mes, ‘-’, dia), ‘%Y-%m-%d’ ) AS fecha FROM eventos) AS resultado

I use this line to:

1. CONCAT the three columns in 1 column
2. convert this new column to date format

Second example

I use this line:

SELECT * FROM (SELECT *, STR_TO_DATE( CONCAT(ano, ‘-’, mes, ‘-’, dia), ‘%Y-%m-%d’ ) AS fecha FROM eventos) AS resultado WHERE fecha >= “2005-5-13″ AND fecha = “$date_1″ AND fecha <= “$date_2″ ORDER BY fecha ASC

hi, it is not the more elegant solution, but for small tables and when the client use text to save a date, it is useful.

Thanks

Satish,
You can use the following query

SELECT rows
FROM `table`
WHERE ’2006-12-13′
BETWEEN STR_TO_DATE( vardatefield1, ‘%Y-%m-%d’ )
AND STR_TO_DATE( vardatefield2, ‘%Y-%m-%d’ )
