Subject Re: Must class qualifier be an entire field?
Date Tue, 27 Feb 2007 14:24:39 GMT
I've not used single-table inheritance, but I'm pretty sure the
qualifier is just a qualifier and completely independent of columns.

It could be "0 = mod(random(), 2)" if the database supported the functions.

In this case, the fastest thing to do is to just test your alternate qualifier.
