Joining two tables?
I am facing some difficulties in joining two tables to display all my records. Here are the sample tables:
Name | year | late attendance
Andy | 2010 | 20
Andy | 2011 | 11
Jack | 2009 | 5
Name | year | early attendance
Andy | 2009 | 5
Andy | 2010 | 10
Joe | 2011 | 3
What I would like displayed is:
Name | year | late attendance | early attendance
Andy | 2009 | | 5
Andy | 2010 | 20 | 10
Andy | 2011 | 11 |
Jack | 2009 | 5 |
Joe | 2011 | | 3
I tried using the joins but I am not able to get it working properly..
Do hope someone can help point me to the right direction to get the display above. Thank you.

Can you post the queries you have tried?
Any reason you have two tables?

this is what you need in my case it is 2 tables #earlyAttendance and #lateAttendance
select ISNULL(e.name,l.Name) as name,
ISNULL(e.[year],l.[year]) as [year],
from #earlyAttendance e
full join #lateAttendance l
