by Hannes Erven (JIRA)

PostgreSQL Dialect does not fully implement NOWAIT locking ---------------------------------------------------------- Key: HHH-6452 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6452 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.6.6, 4.x Reporter: Hannes Erven Priority: Trivial The PostgreSQL dialect should override the following methods from Dialect to fully support NOWAIT locks: @Override public String getForUpdateNowaitString() { return getForUpdateString()+" NOWAIT "; } @Override public String getForUpdateNowaitString(String aliases) { return getForUpdateString(aliases)+" NOWAIT "; } The syntax is documented at http://www.postgresql.org/docs/8.2/static/sql-select.html A possible workaround is to implement a custom PostgreSQL dialect, like discussed in https://forum.hibernate.org/viewtopic.php?p=2426758 . -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-7302) HQL uses multiple column Types in a inconsitent manner between Where and Order By clauses

by Miek Dunn (JIRA)

HQL uses multiple column Types in a inconsitent manner between Where and Order By clauses ----------------------------------------------------------------------------------------- Key: HHH-7302 URL: https://hibernate.onjira.com/browse/HHH-7302 Project: Hibernate ORM Issue Type: Bug Components: query-hql Affects Versions: 4.1.0 Environment: Java 1.7.0 Eclipse 3.7.2 Reporter: Miek Dunn When a type maps to multiple columns and that type is used in HQL the generated SQL will order the values in different manner in the Order By clause then it does in the Where clause. The Order By clause assumes the fields are mapped in order of importance, while the where clause assumes not field is more important then any other. For example assume a database stores a timestamp you using multiple fields (T2SCEN T2SYER T2SMTH T2SDAY T2STIM : century year month day time) and that there is a type that turns those fields into a Calendar. Now that type is used in an entity class named WorkOrder with a field named scheduled. The following HQL query: {quote} Select wo From WorkOrder wo WHERE wo.scheduled > :scheduled Order By wo.scheduled {quote} Will generate the following SQL {quote} select ... from SVDSPT workorder0_ where workorder0_.T2SCEN>? and workorder0_.T2SYER>? and workorder0_.T2SMTH>? and workorder0_.T2SDAY>? and workorder0_.T2STIM>? order by workorder0_.T2SCEN, workorder0_.T2SYER, workorder0_.T2SMTH, workorder0_.T2SDAY, workorder0_.T2STIM {quote} The Order By clause will order the values as one would expect for date, that is 2012-05-03T12:12:12 comes after 0001-12-01T00:00:00. The Where clause on the other hand implies that 2012-05-03T12:12:12 does not come after 0001-12-01T00:00:00, since the month 5>12 will be false. -- This message is automatically generated by JIRA.
