Duncan -

Try this:

SELECT name FROM volunteers +
  WHERE name IN +
  (SELECT name FROM volunteers where year = 2003 AND totalhours < 100) +
  AND name IN  +
  (SELECT name FROM volunteers where year = 2004 AND totalhours < 100)

Thanks Randy but the data base is very simple name, year, total hours.
 
the printout looks like this
 
name                               total hours.                       year, 
 
john smith                            155                              2003
harry brown                           95                               2003
john smith                            100                              2004
harry brown                            85                             2004
john smith                            105                              2005
harry brown                          155                             2005
 
All I want to do is be able to is extract a report that will show those who
have performed <100 hours over several consecutive years. If I choose the
years 2003 and 2004 ,in the example above the report would show harry brown.

Duncan,
 
Suppose your table looks like:
VolunteerName, ServiceDate, StartTime, EndTime
 
Tom Smith, 11/1/2001, 09:30:00, 11:30:00
Tom Smith, 11/15/2001, 06:00:00, 16:00:00  
Tom Smith, 01/17/2002, 04:30:00, 06:30:00
 
CREATE VIEW vwVolunteerHours + 
(VolunteerName, Hours2001, Hours2002, Hours2003, Hours2004, Hours2005,
Hours2006) + 
AS SELECT + 
VolunteerName, + 
(IFEQ( (IYR(2001)),((EndTime-StartTime)/60),0 )),
(IFEQ( (IYR(2002)),((EndTime-StartTime)/60),0 )),
(IFEQ( (IYR(2003)),((EndTime-StartTime)/60),0 )),
(IFEQ( (IYR(2004)),((EndTime-StartTime)/60),0 )),
(IFEQ( (IYR(2005)),((EndTime-StartTime)/60),0 )),
(IFEQ( (IYR(2006)),((EndTime-StartTime)/60),0 ))
 
Tom Smith,  2,0,0,0,0,0
Tom Smith, 10,0,0,0,0,0
Tom Smith,  0,2,0,0,0,0
 
CREATE VIEW vwSumVolunteerHrs + 
(VolunteerName, Hours2001, Hours2002, Hours2003, Hours2004, Hours2005,
Hours2006) + 
AS SELECT + 
VolunteerName, + 
SUM(Hours2001) + 
SUM(Hours2002) + 
SUM(Hours2003) + 
SUM(Hours2004) + 
SUM(Hours2005) + 
SUM(Hours2006) +
GROUP BY VolunteerName
 
Tom Smith, 12,2,0,0,0,0
 
Then you can get your list by using a query such as:
 
SELECT VolunteerName + 
FROM vwSumVolunteerHrs + 
WHERE + 
Hours2001 < 50 AND + 
Hours2002 < 50 AND + 
Hours2003 < 50 AND + 
Hours2004 < 50 AND + 
Hours2005 < 50 AND + 
Hours2006 < 50  
 
That will list each volunteer whose hours are less than 50 in every year.
 
By creating views as illustrated, you may not need a report.  You can
simply: 
 
BROWSE ALL + 
FROM vwSumVolunteerHrs + 
WHERE + 
Hours2001 < 50 AND + 
Hours2002 < 50 AND + 
Hours2003 < 50 AND + 
Hours2004 < 50 AND + 
Hours2005 < 50 AND + 
Hours2006 < 50  
 
If you only care about 2003 and 2004, your query can include only those
years:
 
SELECT VolunteerName from vwSumVolunteerHrs + 
FROM vwSumVolunteerHrs + 
WHERE + 
Hours2003 < 50 AND + 
Hours2004 < 50 

If your table has only the hours volunteered, your first view will be
simpler than what I showed.
 
Of course, you can change your select statements into views if you look at
this data very often:
 
CREATE VIEW vw2003LT50 + 
VolunteerName, Hours2003 + 
AS SELECT + 
VolunteerName, + 
Hours2003 + 
FROM vwSumVolunteerHrs + 
WHERE + 
Hours2003 < 50

        I have a table holds the following information 
        
        - the volunteers name
        - The hours volunteered for the year by each volunteer. 
        (This info is held for multiple years ie 2001, 2002, 2003 etc).
        
        I am using the Object Manager- Reports and the Where Builder  and am
trying
        to create a query that will display all volunteers who have done
less than
        50 hours, each year, over a number of years ie 2003 and 2004. I am
having a
        problem as I'm not very good at these compound queries. I had  tried
the
        following but got back no rows. (year =2003 and totalhours <100) and
        (year=2004and totalhours <100).
        
        I would appreciate any help.
        
        Thanks
        Duncan
