select tb2.* from tb1, tb2 where tb1.id = tb2.idtb1 and tb1.id = 2
idtb1 is a multiple value field which contains multiple id from tb1
the reverse query (the other side of the relasionship) will be:
select tb1.* from tb1, tb2 where tb2.id = 5 and tb2.idtb1 = tb1.id
in term of sql query there is no difference between 1 to n and n to n
relasionship, the database engine will do a join on a multiple value field
automatically...

Ced.

What does the SQL look like to access this?

Subject: RE : [Hibernate] livelink collections server
Hello,
The livelink product handles n to n relationship without intermediate
table but with a field with multiple values. Is it possible to instruct
Hibernate to comply to this? if so how do I do it? via the dialect?
Regards,
Ced.

A custom Dialect should be enough, although you may need to
appropriately set some configuration properties as well...
The best thing to do is to simply try running the Hibernate
test suite
using your custom dialect; that'll give you an idea of what
type/level
of SQL support Hibernate is expecting that this particular
database
may/may not provide.

Subject: [Hibernate] livelink collections server
Hello,
I'm just wondering what do I need to do to support another
database
vendor with Hibernate 3.1 ?
The database is LiveLink Collections Server from OpenText (known
previously as Basis) and they provide a JDBC driver.
So far I've seen that I need to write a new implementation of
"org.hibernate.dialect.Dialect" and what else ? any
documentation
related to that subject ? or anything to look at will be
nice... :-)
Regards,
Ced.
