Strip out one of the two duplicate rows

Question

Hi Guys,
I wonder if it is possible to strip out of of the duplicate rows to put it into a "duplicates table" and leave the other one in there i.e.
name id no part
myrows 1 2 3
myrows 1 2 3
thanks,

PS: I heard that in mssql there was a row_over() function that helped with that.

Answer 1

Well
A solution would be
INSERT INTO DUP_TABLE
SELECT <list of fields> from (
SELECT <list of fields> , row_number() over (PARTITION BY <list of fields> order by <a field> ) as rn from source_table)
where rn > 1)
DELETE FROM SOURCE TABLE WHERE ROWID IN (SELECT ROWID FROM (
SELECT rowid , row_number() over (PARTITION BY <list of fields> order by <a field> ) as rn from source_table)
where rn> 1)
where list of fields is all the fields of your table and a field any field of your table.
