Question

I have a query limited by a date range:

select * from mytable 
where COMPLETIONDATE >= TO_DATE('29/06/08','DD/MM/YY')    
and COMPLETIONDATE <= TO_DATE('29/06/09','DD/MM/YY')     

The table is a log for activities for a ticket system. The content may be something like:

ticket_id|activity|completiondate
 1    1       some
 1    2       some
 1    3       some
 1    4       some

 2    1       some
 2    2       some
 2    3       some
 2    4       some

That way I know when each activity was completed.

My problems is, if the completiondate of the first activity happens “before” the date range I loss that info:

where completiondate >= 1 jul 09 and completiondate <= 30 jul 09

ticket_id |activity|completiondate
123    3        1 jul 09
123    4        2 jul 09

In this case I have lost the dates for activity 1 and 2 which took place on june 30 or before.

How can I, at the same time limit the date range of the items I want to show, but also include dates from the same tickets beyond the date range?

This is for a tickets report so I have to see:

Tickets from jun 1 - 30 : 

Page won't load, received: march 20, fixed: jun 15
Change color, received: jun 5, fixed:  in progress... 

etc.

You’re going to need to write a subquery that gets all IDs that have a completion date inside of your range, and then plug that into a query that returns all ticket information for those IDs.

select * 
from mytable
where id in (select id from mytable where 
              COMPLETIONDATE >= TO_DATE('29/06/08','DD/MM/YY')    
              COMPLETIONDATE <= TO_DATE('29/06/09','DD/MM/YY')
)
