[eclipselink-users] updateObject - How do I get the numbers of rows that

[AnaTatavu <ana.tatavu@xxxxxxxx>]

In 90% of the cases , we need to do an update not an insert.
Using writeObject is causing to many db round-trips, since we are almost
sure is an update , not an insert.
We still need to figure out , when the update didn't occurr, so we can do an
insert.
At the end of the next code, I will need to know if all the updates
succeeded(all the rows where found and they were updated).


      beginTransaction(cs);
                for ( Object row : rowList )
                {
                    if ( row != null )
                    {
                          Object query = cs.updateObject(row);
                    }
                }
                commitTransaction(cs);
In the eclipseLink doc is written:
The updateObject method updates existing objects in the database, but does
not perform the does-exist check before it attempts the update operation.
The updateObject is more efficient than the writeObject method if you are
certain that the object does exist in the database. If the object does not
exist, the database throws an exception when you execute the updateObject
method. 
(from http://wiki.eclipse.org/Using_Basic_Query_API_(ELUG))
I don't receive any exception in the case the object doesn't exists.

Thank you,
Ana
