Home -> Community -> Mailing Lists -> Oracle-L -> Re: How to find DUPLICATE KEYS FOUND
"borrowed" from Ari Kaplan of this list:
delete from &table_name a where rowid > (select min(rowid)
from &&table_name b
where a.&column_name=b.&&column_name)
/
this will prompt you for the table that has the dups and the column that has them
you can modify it to add columns, since your index is a concatenated one
