[Hibernate-JIRA] Created: (HHH-2893) Criteria api does not allow a groupProperty to _NOT_ be included in the selected columns

by Antony Stubbs (JIRA)

Criteria api does not allow a groupProperty to _NOT_ be included in the selected columns ---------------------------------------------------------------------------------------- Key: HHH-2893 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2893 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: n/a Reporter: Antony Stubbs When adding a Projections.groupProperty("prop") to a criteria, the property is added to both the GROUP BY and SELECT parts of the generated SQL query. This is a major problem for using the criteria API for complex subselects that require aggregating by a column while grouping by another column. There is presently no way in the criteria API to group by a column and have it _ONLY_ in the GROUP BY clause. i.e. currently Projections.groupProperty("propOne") causes: SELECT propOne, MAX(propTwo) FROM table GROUP BY prop desired option is to have SELECT MAX(propTwo) FROM table GROUP BY prop There have been several people talking about this, but there appears to have been 'no comment'. http://forum.hibernate.org/viewtopic.php?t=939071&highlight=values+groupp... http://forum.hibernate.org/viewtopic.php?t=950803&highlight=groupproperty... http://forum.hibernate.org/viewtopic.php?t=964512&highlight=groupproperty... http://forum.hibernate.org/viewtopic.php?t=957671&highlight=groupproperty... http://forum.hibernate.org/viewtopic.php?p=2317841#2317841 http://forum.hibernate.org/viewtopic.php?t=961617&highlight=groupproperty...

[Hibernate-JIRA] Created: (HHH-3325) Pagination with Oracle ROWNUM is sub-optimal

by e. wernli (JIRA)

Pagination with Oracle ROWNUM is sub-optimal -------------------------------------------- Key: HHH-3325 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3325 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Reporter: e. wernli Pagination with Oracle ROWNUM is sub-optimal The feature works but result in sub-optimal SQL. The generated SQL is the following: select * from ( select row_.*, rownum rownum_ from ( select this_.id as id3_0_, this_.version as version3_0_, this_.name as name3_0_, this_.type as type3_0_, this_.marketstatus as marketst5_3_0_ from Customer this_ order by this_.id asc ) row_ ) where rownum_ <= ? and rownum_ > ? But this SQL is faster: SELECT * FROM (SELECT row_.*, ROWNUM rownum_ FROM (SELECT this_.ID AS id3_0_, this_.VERSION AS version3_0_, this_.NAME AS name3_0_, this_.TYPE AS type3_0_, this_.marketstatus AS marketst5_3_0_ FROM customer this_ ORDER BY this_.ID ASC) row_ WHERE ROWNUM <= ?) WHERE rownum_ > ? The second solution allows Oracle to use an optimization that can dramatically reduce the time of the query, especially one of the first page is retrieved.

[Hibernate-JIRA] Created: (HHH-2473) fetch="join" and property-ref

by David CLEMENT (JIRA)

fetch="join" and property-ref ----------------------------- Key: HHH-2473 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2473 Project: Hibernate3 Type: Improvement Versions: 3.2.1 Environment: Version 3.2.1, not DB dependant Reporter: David CLEMENT When Hibernate does a fetch join with a property-ref in a many-to-one, it issues the join SQL query but needs another select to find the associated entity by property-ref. It should be able to use the entity fetched in the join instead (maybe this has been done to ensure the unicity of the associated entity, but it introduce a performance issue). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2578) redesign SessionFactory building

by Steve Ebersole (JIRA)

redesign SessionFactory building -------------------------------- Key: HHH-2578 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2578 Project: Hibernate3 Issue Type: Improvement Components: core Reporter: Steve Ebersole Assignee: Steve Ebersole Priority: Critical Fix For: cfg-rework Currently a SessionFactory is built by throwing a bunch of stuff into a Configuration object, stirring it, letting it come to a boil, and then pulling out the SessionFactory. In seriousness, there are a few problems with the way we currently operate within a Configuration and how we use it to build a SessionFactory: The general issue that there is no "lifecycle" to when various pieces of information will be available. This is an important omission in a number of ways: 1) consider schema generation. currently we cannot even know the dialect when a lot of db object names are being determined. this would be nice because it would allow us to transparently handle table/column names which are also keywords/reserved-words in the dialect, for example. 2) static-ness of types and the type-mappings. Because we currently have nothing to which to scope them. Ideally a type instance would be aware of the SessionFactory to which it is bound. Instead, what we have now is to change API methods quite a lot of the time to add in the SessionFactory as a passed parameter whenever it is discovered that it is needed. 3) also, most (all?) of the "static" configuration parameters in Hibernate are currently required to be so because of their use from within these static types; thus scoping types would allow us to also scope those config parameters (things like bytecode-provider, use of binary streams, etc). Ideally what I see happening is a scheme where users build a org.hibernate.cfg.Settings (or something similiar) instance themselves. Additionally they would apply metadata to a registry of some sort (lets call it MetadataRegistry for now). Then in order to build a SessionFactory, they would supply these two pieces of information (via ctor? via builder?). The important aspect though is that the information in MetadataRegistry would not be dealt with until that point in time, which would allow us to guarentee that resolving schema object names, types, etc would have access to the runtime Settings (and specifically the dialect) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
