I need a SQL query for retrieving data which is included in selected time

I need a SQL query for retrieving data which is included in selected time period, time period is string which user selects from calendar.

For example, if user selects time period ‘2012-07-01’ to ‘2012-07-04’ and I have the following table:

ID ||  start_date  ||  end_date
 1 ||  2012-07-02  || 2012-07-04
 2 ||  2012-07-06  || 2012-08-05
 3 ||  2012-07-01  || 2012-09-01
 4 ||  2012-06-25  || 2012-09-01

If a write a sql query like this:

SELECT ID, start_date, end_date
FROM   TABLE
WHERE  start_date BETWEEN '2012-07-01' AND '2012-07-04'

This returns all rows which started from ‘2012-07-01’ to ‘2012-07-04’

ID ||  start_date  ||  end_date
 1 ||  2012-07-02  || 2012-07-04
 3 ||  2012-07-01  || 2012-09-01

But, I want all data which is included in this period, so result must be:

ID ||  start_date  ||  end_date
 1 ||  2012-07-02  || 2012-07-04
 3 ||  2012-07-01  || 2012-09-01
 4 ||  2012-06-25  || 2012-09-01

Row with ID 4 also I want to be in result, because user selected time period is under start_date and end_date.

    SELECT ID, start_date, end_date
FROM   TABLE
WHERE  start_date BETWEEN '2012-07-01' AND '2012-07-04'

    You are only selecting by start date, you may ask by:

    (start_date between begin, end) OR
(end_date   between begin, end) OR
(start_date <= begin AND end_date >= end)

    so:

    (start_date between begin, end ): you have all events that starts in the range

    (end_date between begin, end): you have all events that finish in the range

    (start_date <= begin AND end_date >= end): you have all events that are active in the range
