Check the EXCEPTIONS clause of the ALTER TABLE ... ADD CONSTRAINT
command. Create an EXCEPTIONS table, create a unique constraint on the
columns which *should* be unique, then proceed as follows :
create table nodup
as select distinct * from my_table
where rowid in (select row_id from exceptions
where table_name = upper('my_table');
(I dislike distinct but sometimes ... :-))
delete my_table
where rowid in (select row_id from exceptions
where table_name = upper('my_table');
insert into my_table
select * from nodup;
drop table nodup;
truncate table exceptions;
and go on with the next table. Write a script which takes a parameter
for all this part, no need to retype it each time.
