Hi, Do we need a primary key column in the database table when we want to call the method Session.delete(String query)?
According the SessionImpl the delete operation is issuing following statements: .... List list = find(query, values, types); .... this creates a list of objects and calls: for ( int i=0; i<size; i++ ) delete( list.get(i) ); to delete objects one by one. Is there a way to execute the delete operation without creating a object list which results from find(...)? i.e. execute DELETE operation directly on the database? Because, I'm working on some data which has about few millions of data this could be a performance problem. could you let me know how to improve some performance with delete operation. regards Lilantha -------------------------------------------------------------------------------------------------- This message, including any attachments, contains confidential information intended for a specific individual and purpose, and is intended for the addressee only.
