Hi All,
I'm stuck with a problem.
I want to use Hibernate Query by Example but am getting a problem with my result.
I'm querying over two tables, a parent-child situation.

I have a class called CheckSum and a class called Record.
CheckSum has a set of Record.
When i execute the query, the resultset of CheckSum is equal to all the resultset of Record.
I'm not getting a parent-child resultset.

Thus is CheckSum has {chk01,chk02,chk03}
chk01 has {rec01,rec02}
chk02 has {rec03,rec04,rec05}
chk03 has {rec06,rec07,rec08}

if I query chk02 and all his record I get a list of 3 CheckSum and in all those 3 the same amount of record is repeated.

How does query by example work with joins???

thanks in advance.

Hi Paul,

Record does have a primary key and so does checksum

This is the record class:



this is the hibernate record mapping:


This is the checksum class:


this is the checksum hibernate mapping:
