Re: [eclipselink-users] Object Version in Eclipse Link

I have another question

Say for example there is table code with following column

Code StartDate   EndDate (dd/mm/yyyy)
1       1/1/2008  5/1/2008
2       3/1/2008  9/1/2008
3       4/5/2008  7/5/2008

Business RUle
 1. Insert the code based on non-overlapping time intervals
 2.There will bulk inserts (say in the order of few millons)

  As a result code 1,3 are fine, code 3 should generate the error message :-
Not valid time interval

Suggest some optimized way to perform this.

Eagerly awaiting reply
