I wouldn't advocate it, but a second table, the PK of which FKs the
first table.  Then you can do a COUNT() to see if there's a date set
for an entity.  Or a LEFT JOIN, in which case you still get NULLs
returned but at least you're not storing them in the database.

Like I said, I wouldn't advocate it.  As we've all said, this is what
NULLs were made for.
