[Hibernate-JIRA] Created: (HHH-4562) Some kind of typo in chapter 7.3.1

by Sorin Postelnicu (JIRA)

Some kind of typo in chapter 7.3.1 ---------------------------------- Key: HHH-4562 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4562 Project: Hibernate Core Issue Type: Bug Components: documentation Affects Versions: 3.3.2 Reporter: Sorin Postelnicu Priority: Trivial In the example shown in chapter 7.3.1 here: http://docs.jboss.org/hibernate/core/3.3/reference/en/html/associations.html The following line seems incorrect: create table PersonAddress ( personId not null, addressId bigint not null primary key ) Shouldn't it have been as follows? create table PersonAddress ( personId bigint not null, addressId bigint not null ) Even such simple things can be confusing for people who are just learning to develop database applications with hibernate. They usually assume that the manual is "bug-free" and can be followed word-to-word, as a definitive reference documentation. -- 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: (HSEARCH-726) Facetted search on embedded collections takes only first element from collection

by Elmer van Chastelet (JIRA)

Facetted search on embedded collections takes only first element from collection -------------------------------------------------------------------------------- Key: HSEARCH-726 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-726 Project: Hibernate Search Issue Type: Bug Components: query Affects Versions: 3.4.0.CR2, 3.4.0.CR1, 3.4.0.Beta1, 3.4.0.Alpha1 Environment: Any valid config I suppose, tested using Hibernate Core 3.6.3 + Search 3.4.0.CR2, mysql and in Hibernate Search test environment Reporter: Elmer van Chastelet Attachments: EmbeddedCollectionsFacetsTest.zip >From [Hibernate Search Forum: Bug or not? Faceted search + embedded fields (*tomany)|https://forum.hibernate.org/viewtopic.php?f=9&t=1010472&start=0]. Faceted search won't work correctly when used on collections. For the cause I quote Hardy Ferentschik : ??The current faceting implementation utilizes the Lucene FieldCache which has a limitation that each document must have a single value for the specified field.?? I can think of many use cases in which faceted search on collections is really needed, some examples: Facetting on authors when searching for publications Facetting on ingredients when searching for recipes Facetting on actors when searching for movies ... Attached is a hibernate search test case. It fails on retrieving the right amount of matched authors. Currently I don't have the needed insight to suggest an improvement on current implementation to make it compatible with collections. Hopefully it can be achieved with small changes. Good luck :) -- 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-2776) Restrictons.in(..) generates invalid SQL if list of values is empty

by Adrian Smith (JIRA)

Restrictons.in(..) generates invalid SQL if list of values is empty ------------------------------------------------------------------- Key: HHH-2776 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2776 Project: Hibernate3 Issue Type: Bug Components: query-criteria Affects Versions: 3.2.2 Environment: Hibernate 3.2.2.ga, MySQL 4.1.18, Windows XP Reporter: Adrian Smith I have classes called A and B. There is a 1:n relationship from A to B. Class B has the following in its mapping file: <many-to-one name="a" class="A" column="fk_a_id" not-null="true" /> If I write the following code: List<B> foo() { List<A> aList = .... Session session = .... Criteria query = session.createCriteria(B.class); query.add(Restrictions.in("a", aList)); return query.list(); } Then all works fine and the results I want are returned. However, if aList is empty (i.e. aList.size()==0) then the query.list function generates and executes invalid SQL for MySQL. java.sql.SQLException: Syntax error or access violation message from server: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1" I imagine that it is generating SQL like IN () which isn't valid. I realize it's a bit ridiculous to want to find the rows where a field is IN the empty list. Nothing will ever be returned. However, in my opinion it should still be allowed, and return no rows, just as saying "WHERE 1=2" is allowed, just doesn't return any rows. -- 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
