Well, you could fix your "bad planning" by just altering your table.
Create a new column, then use
UPDATE your_table SET new_column = 0 where old_column = 'N';
Set it to one for 'Y', drop the old column, rename the new column, and
your done. Well, you'd have to do it for five columns, but it would
"fix" it at least.
Or you could use something like this:
SELECT * FROM your_table WHERE
LENGTH(REPLACE(CONCAT(enum1,enum2,enum3,enum4,enum5),'N','')) > 1)
That'll join all the enums together, like 'YNYNN', replace all N with an
empty string, resulting in 'YY', and then make sure the length is more
than one, i.e. there are more than two 'Y' in the string.
Hope that helps.
