I want the source code to a Java class that will delete redundant
records in a MySQL table.  The table has five fields and due to an
error in code that populated the table, I now have several redundant
records spread throughout it.  I want to run a simple program that
will delete these rendundant records and leave only one unique record.
there is shareware that does this for about $20, but it doesn't work
well, and I'd like the simple code that does this anyway.

Fortunately because mysql doesnt't really have much by way of
referential action that I know of, it is pretty easy to do.  Let's
call the table you are cleaning up A.  Create a table with the same
schema B.  Then run the following sql in this order:
insert into B
select distinct * from A;
-----
Delete from A;
----
insert into A
select * from B;
------
drop table B;

good answer!  it worked
