[Hibernate-JIRA] Commented: (HHH-544) select new ... results in n+1 selects

by Adam Skobodzinski (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-544?page=co... ] Adam Skobodzinski commented on HHH-544: --------------------------------------- I was wondering if there are any plans to fix it. Due to n+1 problem it is really not feasible to use the constructor form at the moment. Btw. I am using hibernate 3.6.0 > select new ... results in n+1 selects > ------------------------------------- > > Key: HHH-544 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-544 > Project: Hibernate Core > Issue Type: Improvement > Components: core > Affects Versions: 3.0.5 > Environment: Hibernate 3.0.5, Oracle 8i, JDK 1.4.2 > Reporter: Salvatore Insalaco > Priority: Minor > > Using collection constructors in select clause of HQL (e.g. new map(...)) generates n + 1 SQL statements (one for primary keys, one for each object). > This is a problem when there're clauses as "distinct" and "order by": > select distinct o from MyEntity o order by o.description > works, because in the generated SQL all the columns are mapped in the select clause; but: > select distinct new map (o as result) from MyEntity o order by o.description > doesn't work, because the first line of generated SQL is like: > select distinct id from MyTable order by description > and that's invalid sql (at least in Oracle): description shoud be placed in select clause. -- 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
