[Hibernate-JIRA] Created: (HHH-1994) Problem with case sensitive column and tables names and Identity mapping with postgreSQL

by Alex Samad (JIRA)

Problem with case sensitive column and tables names and Identity mapping with postgreSQL ---------------------------------------------------------------------------------------- Key: HHH-1994 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1994 Project: Hibernate3 Type: Bug Components: core Versions: 3.1.3 Environment: Hibernate 3.1.3, Java 1.5.0_07 (sun) windos and linux ( 32 & 64 bit). POstgres SQL 8.1 Windows and linux Reporter: Alex Samad Whilst trying to insert into a table with a primary key (ID mapping) which has a identity generator. And the columns and/or the table has been defined with case sensitivey ie back ticks. It fails to get the next serial number and thus fails any inserts. The problem lies in dialect/PostgreSQLDialect.java public String getIdentitySelectString(String table, String column, int type) { return new StringBuffer().append("select currval('") .append(table) .append('_') .append(column) .append("_seq')") .toString(); } table is inclosed in quotes and column is inclosed in quotes which gives a name like "table"_"Column"_seq - which fails I would suggest a fix is to test each of table or column for " and if it exist then to strip it of both of table and column and encluse the whole name in "". This mighe break some old code where say the table is coded in case insensitive table name and case sensitive column key. Sorry not much of a java programmer. -- 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-5790) method BasicBinder#bind() slow because formatting for trace is done also with disabled trace

by Guenther Demetz (JIRA)

method BasicBinder#bind() slow because formatting for trace is done also with disabled trace -------------------------------------------------------------------------------------------- Key: HHH-5790 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5790 Project: Hibernate Core Issue Type: Improvement Affects Versions: 3.6.0 Environment: 3_6_0_final Reporter: Guenther Demetz In the ELSE block of method org.hibernate.type.descriptor.sql.BasicBinder#bind the if statement "if (log.isTraceEnabled())" is missing, so strings are formatted even if trace logging is disabled. CURRENT CODE: if ( value == null ) { if ( log.isTraceEnabled() ) { log.trace(String.format(...); } st.setNull( index, sqlDescriptor.getSqlType() ); } else { log.trace(String.format(BIND_MSG_TEMPLATE,index, ...); doBind( st, value, index, options ); } IMPROVEMENT: if ( value == null ) { if ( log.isTraceEnabled() ) { log.trace(String.format(...); } st.setNull( index, sqlDescriptor.getSqlType() ); } else { if ( log.isTraceEnabled() ) { //// NEW LINE log.trace(String.format(BIND_MSG_TEMPLATE,index, ...); } //// NEW LINE doBind( st, value, index, options ); } BTW: By doing this little code enhancement, I was able to achieve almost the double speed when inserting data. -- 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-5967) Envers Fetching Indexed Collection - Duplicate Row Exception

by Kevin Jordan (JIRA)

Envers Fetching Indexed Collection - Duplicate Row Exception ------------------------------------------------------------ Key: HHH-5967 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5967 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.6.1 Environment: Hibernate 3.6.1, MySQL 5.1.35 Reporter: Kevin Jordan I'm having problems reading from Envers for the revision of something with an indexed collection. Currently the revision shows when things are reordered that there is an entry with a create REVTYPE under the new index and a delete REVTYPE under the old index. When it goes to pull, this causes an "org.hibernate.HibernateException: More than one row with the given identifier was found: {REV=<MyRevisionEntityType>, collection_id=1, obj_id=1}, for class: <MyClass_AUD>". I am using the ValidityAuditStrategy now to try and fix the slowness I was having described in my post at https://forum.hibernate.org/viewtopic.php?f=1&t=1009676, so I'm not sure if that has anything to do with it. -- 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-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-4956) Native Query returns wrong results

by Akashdeep Saddi (JIRA)

Native Query returns wrong results ---------------------------------- Key: HHH-4956 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4956 Project: Hibernate Core Issue Type: Bug Components: query-sql Affects Versions: 3.3.2 Environment: hibernate 3.3.2.GA , linux, oracle 10g, weblogic 10 Reporter: Akashdeep Saddi Issue: In-case running native queries vai hibernate we have two technical ID's in the select clause from join of two or more tables the value of all the id's is set to one value. Example A.id = 1 B.id =2 select A.Id as A_ID, B.Id as B_ID from A, B where A.B_id = B.id will return 1,1 in the result instead of 1,2 Resolution: Use Alias in-case more than one technical keys are part of select clause. Above query works fine when changed as below select A.Id , B.Id from A, B where A.B_id = B.id will return 1,2 -- 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-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-5854) ArrayIndexOutOfBounds on fetching onetoone associations using projections

by Krishna Sundaresan (JIRA)

ArrayIndexOutOfBounds on fetching onetoone associations using projections ------------------------------------------------------------------------- Key: HHH-5854 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5854 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.6.0 Environment: Hibernate version 3.6.0 Reporter: Krishna Sundaresan Attachments: testCase.zip The loading of OneToOne associations using projections results in an ArrayIndexOutOfBounds exception when the results are loaded by the CriteriaLoader. The stacktrace is: {code} Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1 at org.hibernate.loader.criteria.CriteriaLoader.getResultColumnOrRow(CriteriaLoader.java:148) at org.hibernate.loader.Loader.getRowFromResultSet(Loader.java:639) at org.hibernate.loader.Loader.doQuery(Loader.java:829) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:274) at org.hibernate.loader.Loader.doList(Loader.java:2533) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2276) at org.hibernate.loader.Loader.list(Loader.java:2271) at org.hibernate.loader.criteria.CriteriaLoader.list(CriteriaLoader.java:119) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1716) at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:347) at testbed.app.HibernateApp.main(HibernateApp.java:24) Java Result: 1 {code} The problem seems to be with the way the association aliases and types are used in getResultRow. When the types are fetched, all the types that are mentioned in the projection clause are provided whereas when the aliases to be used are fetched SimpleProjection's getColumnCount method seems to be ignoring columns that do not span resulting in a mis-match of array indices. {code:title=From CriteriaLoader.getResultRow(...)} if ( translator.hasProjection() ) { Type[] types = translator.getProjectedTypes(); result = new Object[types.length]; String[] columnAliases = translator.getProjectedColumnAliases(); ... {code} The attached file has a test-case that will demonstrate the problem. Tested that on Hibernate 3.6.0 and derby. I was able to observe this in a case where the association is mapped by a shared primary key but I guess that same should be observable even without a shared primary key. -- 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
