Re: [eclipselink-users] EclipseLink performance

Hi jz,

  You should be able to use a native query to run any pure SQL you want to run. 
 If you are deleting with a native query, you will want to be careful that you 
definitely have not read the object yet since a native query will not remove 
objects from the persistence context or the cache.

  Can you give an example of the query you are running and the SQL that is 
produced that causes your issue with m-1 relationships?
