I have a table, that sometimes has duplicate values...  And I would like to
create an SQL, that will return back to me a count(*) of the number of
duplicates it found, so if my table has this in it...

Table = Tim
field1
--------
1
2
3
3
4
4
4
5

it would return back a count of  *2*  because there were 2 distinct groups
that had duplicates   group (3 and 4).

Is that easily done?

Thanks, tim
