E.g.
Select field1, field2, count(*)
From tablex
Group by field1, field2
Having count(*)>1
But in your scenario i do not know if this is the solution. Question is
if record was changed and in next update "restored" and once again
changed is this duplicate or no?
If yes above query is ok if no then procedure is your friend.
And for the future change your audit trigger and check before if there
was any change
Thank you, but I this isn't quite what I need. I need to match against
all the records of a set (up to 8 rows per set) - not just individual
rows.
