Java – distinct inner connection HQL
•
Java
I have the following hibernate entities
public class Container {
...
@OneToMany
private List<ACLEntry> aclEntries;
}
To protect my container instance, I use the following entities:
public class ACLEntry {
...
private Long sid;
private boolean principal;
private Integer mask;
}
HQL queries will be automatically created to search container instances, @ h_ 404_ 20 @ the following query will be created:
select container from Container container inner join container.aclEntries as aclEntry with bitwise_and (aclEntry.mask,1) = 1 and (aclEntry.sid = :userId or aclEntry.sid = :roleId)
The problem is that the aclentry connection may return 2 results, which will lead to duplicate container results
Who knows how to solve this problem?
Solution
As far as I know, you need a container that can hold multiple entries of the container object. Just replace your HQL query with the following code:
Add select distinct as a native query
