Below query for comparing 2 tables and extract the uncommon like GUID X121 doesn’t exists in the 2nd table and the GUID which are unsuccessful (has –ve values).
select isnull(pt.GUID,Wo.GUIS)as GUID,
pt.[ErrorNo] as Error
from PieTreace pt
full outer join WorkMessage Wm
on pt.GUID = Wm.GUID
where(pt.GUId is null) or (pt.[ErrorNo]<0)
Along with above query I want to extract those,ErroNo and GUID which are unsuccessful for first time and next time(It may be second time or third time)it’s successful, with the lastest date.(I have marked those repeating GUID with red colour.)

Thanks.
