searching data between dates stored in varchar in mysql

Question

I am storing my dates in column server_date_time in varchar in dd/mm/yyyy format and i want to fetch the records lying between some dates so i have

Answer 1

Try this one -

SELECT * FROM activity_emp
WHERE STR_TO_DATE(server_date_time, '%d/%m/%Y')
  BETWEEN '2012-09-29' AND '2012-09-30'

But it is better to store server_date_time in DATETIME data type so that MySQL can use index.
