Comment: was deleted
(was: This patch adds both of the following new methods to Criteria:
{code}
/**
* Join an association using the specified join-type, assigning an alias
* to the joined association.
* <p/>
* The joinType is expected to be one of {@link #INNER_JOIN} (the default),
* {@link #FULL_JOIN}, or {@link #LEFT_JOIN}.
*
* @param associationPath A dot-seperated property path
* @param alias The alias to assign to the joined association (for later reference).
* @param joinType The type of join to use.
* @param withClause The criteria to be added to the join condition
(<tt>ON</tt> clause)
*
* @return this (for method chaining)
*
* @throws HibernateException Indicates a problem creating the sub criteria
*/
public Criteria createAlias(String associationPath, String alias, int joinType, Criterion
withClause) throws HibernateException;
/**
* Create a new <tt>Criteria</tt>, "rooted" at the associated
entity,
* assigning the given alias and using the specified join type.
*
* @param associationPath A dot-seperated property path
* @param alias The alias to assign to the joined association (for later reference).
* @param joinType The type of join to use.
* @param withClause The criteria to be added to the join condition
(<tt>ON</tt> clause)
*
* @return the created "sub criteria"
*
* @throws HibernateException Indicates a problem creating the sub criteria
*/
public Criteria createCriteria(String associationPath, String alias, int joinType,
Criterion withClause) throws HibernateException;
{code})
Adding predicates to the join condition using Criteria Query
------------------------------------------------------------
Key: HHH-2308
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2308
Project: Hibernate Core
Issue Type: New Feature
Components: query-criteria
Affects Versions: 3.2.1
Environment: Linux Using MS SQLServer
Reporter: Ben Grant
Assignee: Steve Ebersole
Fix For: 3.5
Attachments: hibernate-3.3.2.GA-createAlias_withClause.patch,
hibernate-3.3.2.GA-createAlias_withClause.zip, hibernate-joinOn-sorted.ZIP,
hibernate-joinOn.ZIP, hibernate-outer-join-criteria-trunk.diff,
hibernate-outer-join-criteria.diff
I have two tables
Table A
||Col_1||Col_2||
|London| UK |
|Liverpool| UK |
| New York | USA |
Table B
||Col_1||Col_2|| Col_3||
| UK | Europe | 0
| USA | Americas | 1
Using the Criteria class, Restriction Class and FetchMode, Hibernate manages to create a
query that looks like this
select distinct top 2000
this_.Col_1 as y0_, TableB3_.Col2 as y1_
from TableA this_
left outer join TableB TableB3_ on this_.Col_2= TableB3_.Col_1
where TableB3_.Col_3=1
When really i need the query to be like this
select distinct top 2000
this_.Col_1 as y0_, TableB3_.Col2 as y1_
from TableA this_
left outer join TableB TableB3_ on this_.Col_2= TableB3_.Col_1 AND TableB3_.Col_3=1
currently their isn't any know way for hibernate to adjust or apply filters within
the join clause.
