Subject [jira] Commented: (OPENJPA-168) sql optimize n rows query hint
Date Tue, 20 Mar 2007 15:24:32 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12482411
] 

Abe White commented on OPENJPA-168:
-----------------------------------

> when I am executing the 1st select I see 3 eagerKeys in the eagerKey map in the debugger
(dept,mgr,emps) but the selectImpl.hasEagerJoin(toMany) method returns false.So my question
is that inspite of seeing emps in the eagerKey map how come this method returns false.

Because emps is being selected via a parallel select, not a to-many join in the primary select.

> There werre various comments from Patrick, Abe and Kevin Sutter about the code that I
checked related to Optimize hint.  So I have gone back and relooked at this and wil be making
some changes.  At Kevin's suggestion I will do this through a JIRA feature so that folks will
have opportunity to comment on this before the code is actually done and checked in.
