Hi all,
If I have a many-to-many relationship, for instance, between Rugs and
Colors, and I have a list of colors, how do I construct a fetch that
only returns rugs containing only those colors.
So, for example, given colors red, yellow, green, blue for my
qualifier, a rug with red and yellow would match my qualifier, a rug
with all four colors would match the qualifier, but a rug with red,
yellow, green, blue, and purple would not match. Neither would a blue
and purple rug.
I can do it in memory, but I was wondering if someone knew of a trick
that would make this a simple fetch (^_^)
Thanks all,
Ramsey
