Thanks for you answer.
Ok for a simple database call, but when we make this call to the persistence layer, which bring data step by step does it works ?
I make a request on some table with 3 enreg numbers 1, 2 and 5 I ask some iterator at the prsistence layer.
And make next.
Somebody create a new enreg : the number for
When I make next from the number 2. Will I get the number 4 or the number 5 ?
Thanks for any help.

Hi Andre,
To follow an index you'll need an order by clause for the indexed column. (http://db.apache.org/ojb/api/org/apache/ojb/broker/query/Criteria.html#addOrderBy(java.lang.String,%20boolean))
If you do not use an order by clause the RDBMS is not forced to serve rows in a certain sequence.

Hi
When we use *getIteratorByQuery and .next().
* do we move throw the table following the index or in some random order ?
If we go in random order, what is the best way (getting advantage of the cache) to iterate in a table following the index ?
Thank's
Andre
