by James Nobis (JIRA)

ilike support is incomplete --------------------------- Key: HHH-4943 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4943 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Environment: 3.3.2GA MySQL/PostgreSQL Reporter: James Nobis ILIKE is currently supported for PostgreSQL in: hibernate-distribution-3.3.2.GA/project/core/src/main/java/org/hibernate/criterion/IlikeExpression.java: if ( dialect instanceof PostgreSQLDialect ) { return columns[0] + " ilike ?"; } else { return dialect.getLowercaseFunction() + '(' + columns[0] + ") like ?"; } //TODO: get SQL rendering out of this package! 1) This should be in the Dialect 2) PostgreSQL isn't the only DB with ILIKE 3) using instanceof for this is just sloppy 4) this implementation using getLowercaseFunction works with MySQL but fails with DBs like Firebird -- 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] Créée: (HHH-2389) Improving DB2 dialect

by Nicolas Billard (JIRA)

Improving DB2 dialect --------------------- Key: HHH-2389 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2389 Project: Hibernate3 Type: Improvement Components: query-hql Versions: 3.2.1 Environment: Development based on v 3.2.1 Reporter: Nicolas Billard Priority: Minor Attachments: DB2Dialect.java The class joined to this issue overrides the DB2 dialect. The dialect included in hibernate doesn't work very well when you want to limit returned results (when you call setFirstResult and / or setMaxResults on a query) : - the instructions "fetch first XXX row only is not used - a temporary table is used when it's not usefull - when you have subselects, an exception can occur if subselects have order by clause (because of the getRowNumber method, not corrected here). This version of getLimitString() method generates faster requests (tests made on a table of 300000 rows shows that fetching rows from 20 to 30 takes 0.3 seconds with original version, 0.02 with this one). -- 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-4760) NotAuditedException occurs when auditReader.getRevisions() is called for javassist proxies

by Erik-Berndt Scheper (JIRA)

NotAuditedException occurs when auditReader.getRevisions() is called for javassist proxies ------------------------------------------------------------------------------------------ Key: HHH-4760 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4760 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.5.0-Beta-2 Reporter: Erik-Berndt Scheper NotAuditedException occurs when auditReader.getRevisions() is called for javassist proxies In my code I see the following stacktrace if I try to retrieve the revision of a javassist proxy: org.hibernate.envers.exception.NotAuditedException: nl.ibgroep.bap.model.domain.persoon.Ouder_$$_javassist_1 is not versioned! at org.hibernate.envers.reader.AuditReaderImpl.getRevisions(AuditReaderImpl.java:126) at nl.ibgroep.bap.dao.impl.AuditRevisionJpaDaoImpl.getRevisionsFor(AuditRevisionJpaDaoImpl.java:58) Ouder_$$_javassist_1.class is a Hibernate generated javassist proxy for Ouder.class, which is versioned. Code: AuditReader vr = AuditReaderFactory.get(this.entityManager); Class clazz = persistentObject.getClass(); List<Number> revisionNumbers = vr.getRevisions(clazz, persistentObject.getId()); I am able to work around this issue with the following code: AuditReader vr = AuditReaderFactory.get(this.entityManager); Class clazz = persistentObject.getClass(); if (persistentObject instanceof javassist.util.proxy.ProxyObject) { if (LOGGER.isDebugEnabled()) { StringBuilder output = new StringBuilder("Found javassist ProxyObject for revision: class= "); output.append(clazz.getSimpleName()); output.append("; superclass= ").append(clazz.getSuperclass().getSimpleName()); output.append("; interfaces= ").append(Arrays.asList(clazz.getInterfaces()).toString()); LOGGER.debug(output.toString()); } clazz = clazz.getSuperclass(); } List<Number> revisionNumbers = vr.getRevisions(clazz, persistentObject.getId()); However, a fix in envers would be greatly appreciated. -- 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-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.

[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.
