Question

i have a table with the follwoing structure

id   g_id   name    status
---------------------------------------
1   111     item1   1
2   111     item2   1
3   111     item3   1

6   113     item1   -1
7   113     item2   1
8   113     item3   1

9   114     item1   1
10  114     item2   2

status can contains values ,
success : 1
Failed : -1
In progress : 2

Need the following output 
GroupID     Status
------------------
111         Success
113         Failed
114         In-Progress

If one in the group is -1, result should be Failed and if all is 1 then it should be Success. Also if some are 1 and rest is 2 result should be In Progress.
What is the best way i can select the above results?

SQL FIDDLE EXAMPLE

select
    g_id as GroupID,
    case
        when min(status) = -1 then 'failed'
        when max(status) = 2 and min(status) = 1 then 'in progress'
        when max(status) = 1 and min(status) = 1 then 'success'
    end as Status
