This isn't a perfect solution, but you could alter the table to include a
unique id column:
	alter table aaa add column id int unsigned not null auto_increment, add key
(id);
(My test table was aaa -- real original, I know.) On my table, the new
column had a unique id generated as part of the alter.

Then, you can use a two-step process to knock the row out:
	select * from aaa where col1='abc' and col2='def' and col3='ghi' limit 1;
	delete from aaa where id=1;

It would be pretty cool if the following would work:
	delete from aaa where col1='abc' and col2='def' and col3='ghi' limit 1;
However, the LIMIT phrase isn't valid in a delete.

Hope this helps a bit!
