[Hibernate-JIRA] Created: (HHH-2158) incorrect hql query on one-to-one with property-ref

by Sebastien Cesbron (JIRA)

incorrect hql query on one-to-one with property-ref ---------------------------------------------------- Key: HHH-2158 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2158 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.ga Environment: hibernate 3.2.0.ga with firebird 1.5.3 and jaybird 1.5.5 driver on windows XP Reporter: Sebastien Cesbron Attachments: testhib.zip I have a one-to-one relationship with property-ref between Master and Slave2. I want to find all Master instances that have a null Slave2 instance associated. To do so my query is select master from Master master where master.slave2 is null The sql generated is select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_ where master0_.oid is null which seems incorrect. It checks here Master instances with null id (config files are listed below). If I do my query like this select master from Master master where master.slave2.oid is null the generated sql is ok : select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_, Slave2 slave2x1_ where master0_.oid=slave2x1_.myMaster and (slave2x1_.oid is null) I have attached a small eclipse project that reproduces the problem This problem may-be related to the one I have submitted as issue HHH-1849 -- 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-7019) SQLServer2005Dialect, SQLServer2008Dialect issues with subqueries

by Matthew Brock (JIRA)

SQLServer2005Dialect, SQLServer2008Dialect issues with subqueries ----------------------------------------------------------------- Key: HHH-7019 URL: https://hibernate.onjira.com/browse/HHH-7019 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 3.6.9 Environment: Microsoft SQLServer 2005, Microsoft SQLServer 2008 Reporter: Matthew Brock Priority: Minor Attachments: SQLServer2005Dialect.java There are a few bugs with the way the SQLServer2005Dialect is generating the pseudo-limit wrapper (ROW_NUMBER() OVER). --- #1: Indeterminate return results when strings are returned from subqueries line 116: StringBuilder sb = new StringBuilder(querySqlString.trim().toLowerCase()); Take the following example: @Formula("(select case when name = 'Smith' then 'Neo' else name end)") public String getName() { ... } toLowerCase() will lose any capitalization in subselects and break the CASE statement. FIX: Move toLowerCase() test down the chain, don't modify original query. --- #2: GenericJDBCException whenever subqueries are part of a SELECT line 118: int orderByIndex = sb.indexOf("order by"); line 147: int distinctIndex = sql.indexOf(DISTINCT); line 163: sql.substring(sql.indexOf(SELECT) + SELECT.length(), sql.indexOf(FROM)); This issue stems from using indexOf() to search the original SQL for specific keywords that could possibly exist in subqueries (@Formulas tend to be the biggest offenders). Example: @Formula("(select distinct(a.zip) from address a where a.person_id = id") public String getZip() { ... } The DISTINCT and FROM keywords will break the query generation. FIX: Since all @Formulas are wrapped in parenthesis when they are aliased, I simply count the number of open parenthesis when doing an indexOf() search on SQL statements and ignore any results if the number of open parenthesis doesn't equal 0. -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-7116) Ordered Criteria query that joins with an ordered mapped collection results in incorrect overall ordering

by Tommy Knowlton (JIRA)

Ordered Criteria query that joins with an ordered mapped collection results in incorrect overall ordering --------------------------------------------------------------------------------------------------------- Key: HHH-7116 URL: https://hibernate.onjira.com/browse/HHH-7116 Project: Hibernate ORM Issue Type: Bug Components: core, query-criteria Affects Versions: 4.1.0, 3.6.10 Reporter: Tommy Knowlton A criteria query for Items that joins (with sub-criteria or alias) Bids, where mapped Bids collection is ordered [e.g., @OrderBy("bidamount desc")] and where the criteria query is ordered by Item descriptions [c.addOrder(Order.asc("description"))] will result in generated SQL having incorrect overall ordering: the ordering specified by the mapped association is output first, followed by the ordering specified on the criteria. Using the example, it ends up looking like "order by bid3_.AMOUNT desc, this_.DESCRIPTION asc". There are actually two issues here. The first is that the association's ordering is overriding the criteria's ordering. Instead of having Items ordered alphabetically by description, and each Item's bids ordered by decreasing bid amounts, we have Items ordered from those having highest bids, down to those having lower bids, with alike bids ordered by description, alphabetically. It ends up being a simple matter to fix this issue in the "JoinWalker" base class. The second issue is that in cases where a mapped association has an ordering specified, there is really an implied ordering by primary (or natural) key of the owning entity that has higher precedence than the association ordering. In the Items/Bids example, think about what happens to the criteria query if two items happen to have the same description text, and each has many bids: the result rows will be interleaved. It probably ends up being an implementation detail of the result transformer whether that matters or not, but I think that a "more correct" or at least less-surprising behavior would be for the "JoinWalker" to output orderby subclauses in such a way as to make the implied ordering (that keeps owning entities together in the resultset) explicit. -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-6829) PooledLoOptimizer.generate() should be synchronized

by Manuel Dominguez Sarmiento (JIRA)

PooledLoOptimizer.generate() should be synchronized --------------------------------------------------- Key: HHH-6829 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6829 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.8 Reporter: Manuel Dominguez Sarmiento Priority: Critical We recently switched to this ID generation optimizer in our highly concurrent production platform, and began getting random id / PK collision errors very often. Checking the code, it's pretty obvious that the problem lies with generate() not being synchronized. All other optimizers (PooledOptimizer, LegacyHiLoAlgorithmOptimizer, HiLoOptimizer, etc.) are synchronized - PooledLoOptimizer should be as well. -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-4083) Custom sql-delete does improper parameter handling

by ggsoft＠gmx.net (JIRA)

Custom sql-delete does improper parameter handling -------------------------------------------------- Key: HHH-4083 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4083 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.2.6 Environment: 3.2.6GA, MySQL 5.0.75 Reporter: ggsoft(a)gmx.net With turned on versioning (timestamp) e.g. <version name="lastupdated" type="timestamp" /> a custom delete query <sql-delete>UPDATE myentity SET deleted = 1 WHERE myentityid = ?</sql-delete> gives an exception on wrong parameter (2 having, only 1 to set) Hibernate tries to set the version field too so i integrated it to the query: <sql-delete>UPDATE myentity SET deleted = 1, lastupdated = ? WHERE myentityid = ?</sql-delete> this gives an exception because hibernate sets lastupdated to the id and myentityid to timestamp in the resulting statement.

[Hibernate-JIRA] Created: (HHH-5719) Applying projection to criteria with restricted subcriterias generates wrong SQL

by Victor Cherkassky (JIRA)

Applying projection to criteria with restricted subcriterias generates wrong SQL -------------------------------------------------------------------------------- Key: HHH-5719 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5719 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.2.0.ga Environment: Hibernate 3.2.0 GA Reporter: Victor Cherkassky Priority: Minor Detailed issue description and solution is here http://facingtech.blogspot.com/2010_09_01_archive.html I will describe only the technical aspect of the issue here. Considuer the following model. There is an entity {{User}}, which is in relation with {{Workplace}}. While {{Workplace}} has an {{Activity}} (the purpose of this workplace). Each {{Activity}} has a collection of {{Description}} entities ({{Description}} entities are just the same {{Activity}} description translated into several languages, thus having locale property). Result of the query should look like this: ||User.name||Workplace.name||Activity.code||Description.text|| |John|Main office|R|Research| |Polly|Main office|R|Research| |Craig|Main office|R|Research| Here is the criteria for getting that result: {code} Criteria criteria = session.createCriteria(User.class); criteria.createAlias("workplace.activity.descriptions", "descriptionsAlias", Criteria.INNER_JOIN); criteria.add(Restrictions.eq("descriptionsAlias.locale", "en_US")); criteria.list(); {code} It works just fine. Produces the table shown above and generates SQL like this: {code} select this_.id as id18_3_, this_.name as name18_3_, this_.workplaceId as workplac3_18_3_, workplace3_.id as id111_0_, workplace3_.activityId as activityId111_0_, workplace3_.name as name111_0_, activity4_.id as id114_1_, activity4_.code as code114_1_, descriptio1_.id as id24_2_, descriptio1_.locale as locale24_2_, descriptio1_.text as text24_2_ from user this_ left outer join workplace workplace3_ on this_.workplaceId=workplace3_.id left outer join activity activity4_ on workplace3_.activityId=activity4_.id inner join description descriptio1_ on activity4_.id=descriptio1_.activityId where descriptio1_.locale=? {code} While if you want paging, you should make a rowcount projection first, so your query will look like this: {code} Criteria criteria = this.sessionFactory.getCurrentSession().createCriteria(User.class);}} criteria.createAlias("workplace.activity.descriptions", "descriptionsAlias", criteria.INNER_JOIN); criteria.add(Restrictions.eq("descriptionsAlias.locale", "en_US")); criteria.setProjection(Projections.rowCount()); Integer rowCount = (Integer) criteria.uniqueResult(); {code} And you expect Hibernate to produce this SQL: {code} select count(*) as y0_ from user this_ left outer join workplace workplace3_ on this_.workplaceId=workplace3_.id left outer join activity activity4_ on workplace3_.activityId=activity4_.id inner join description descriptio1_ on activity4_.id=descriptio1_.activityId where descriptio1_.locale=? {code} But the SQL produced is this: {code} select count(*) as y0_ from user this_ where descriptio1_.locale=? {code} I suppose that this is a bug, because you expect one behavior, while you get another. I don't think, that this is a big deal, but when you experience such an issue, it is time consuming to get it fixed. Here is a workaround (or fix) of the issue. You should always assign aliases to all associated "links" of the "entities chain" of the path to an entity you want to restrict if you use projections. In other words, if you have anything in where clause and you are using projections, you should assign aliases to all associations between root entity and the entity, fields of which are used in where clause. This criteria {code} Criteria criteria = this.sessionFactory.getCurrentSession().createCriteria(User.class); criteria.createAlias("workplace", "workplaceAlias"); criteria.createAlias("workplaceAlias.activity", "activityAlias"); criteria.createAlias("activityAlias.descriptions", "descriptionsAlias", Criteria.INNER_JOIN); criteria.add(Restrictions.eq("descriptionsAlias.locale", "en_US")); criteria.setProjection(Projections.rowCount()); Integer rowCount = (Integer) criteria.uniqueResult(); {code} Produces the right result {code} select count(*) as y0_ from user this_ inner join workplace workplacea1_ on this_.workplaceId=workplacea1_.id inner join activity activityal2_ on workplacea1_.activityId=activityal2_.id inner join description descriptio3_ on activityal2_.id=descriptio3_.activityId where descriptio3_.locale=? {code} -- 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
