Question

I have a table with the following structure

leave_id    int(10)     No           
user_id     int(10)     No           
leavetype_id    int(15)     No           
fromdt  date    No           
todt    date    No           
no_of_days  varchar(10)     No           
status  enum('0', '1', '2', '3')    No           
modifier    varchar(35)     No           
modifiedby  varchar(25)     No           
description     varchar(100)

which contains data like this

leave_id        194
user_id     2
leavetype_id    2
fromdt          2011-04-26
todt            2011-05-09
no_of_days  9
status          3
modifier     
modifiedby   
description     some description

Now I need to search based on the leave date. For eg I want to see the leaves a user taken f( for eg user_id = 2) between 2011-04-27 and 2011-05-08. As you can see, as per the result posted above the user_id 2 was on leave from 2011-04-26 to 2011-05-09. And the given date 2011-04-27 and 2011-05-08 comes between that.

I have tried the following things

• Between AND
• Less than Greater than

Answer 1

The following will show any leave that has at least 1 day in common with the period between '2011-04-27' and '2011-05-08' :

SELECT *
FROM yourtable
WHERE fromdt <= '2011-05-08'
  AND todt >= '2011-04-27' 

This will show the leaves that spanned the whole period '2011-04-27' to '2011-05-08' :

SELECT *
FROM yourtable
WHERE fromdt <= '2011-04-27' 
  AND todt >= '2011-05-08'
