Question

I have a column which has the data like 2012-09-09 13:20:00, when I try to query the table, with the following query, it doesn’t include the data on the to date.

Procedure test (IN fromdate date, IN todate date)

Select * from table where date between fromdate and todate

Let’s say the user put in 2012-08-10 to 2012-09-09, then it doesn’t include the data on the 9th Sept. However, if I change the to date to 2012-09-10, then it will include the data. It seems like when there is no time included, mySQL defaults to midnight or 00:00:00

Is there a way to change it or a way around this? Such as, joining the time (23:59:59) to todate at some stage? i.e. using the following

set todate = todate.STR_TO_DATE("23:59:59");

Answer 1

You should use > and < operators instead of BETWEEN as it is not inclusive with regards to dates (assuming your column is datetime). If you only specify 2011-01-31, it is the equivalent of 2011-01-31 00:00:00.

Example:

SELECT * FROM t1 WHERE date > DATE_SUB(fromdate, INTERVAL 1 SECOND) 
     AND date < DATE_ADD(todate, INTERVAL 1 DAY)
