Title: SV: Dynamic finders
Yes.
If you want to go pure, you could do something like:
a) get them all and then filter them in your code
b) get the largest hit first, then filter them with the collections returned by your other finders (requires one finder per dynamic value of original query). This filterting should probably be located in a Session bean.
c) generate finder methods for all possible queries and have a Session bean select the one you want
Having been in your shoes, I dropped religion and went with tech. :)

Although it may be technically correct, but from conceptual database
modeling point of view the comparison ($1 is null... ) is
questionable.

Amne: Dynamic finders
Does anybody have a solution for implementing a finder that
takes some
parameters, but searches taking into account only the ones
that are not
null?
Basically, this would be used to support a search page in
which the user
can choose to fill or not some fields of the search criteria.
I know that probably the best way to do this is using a
Session Bean and
JDBC, but is there a way to implement it using CMP Entity
finders (in
EJB1.1)?
Thanks,
Stefan
