Re: Feature proposal for JDO 2.1 maintenance: current DB time

[Craig L Russell]

It's easy enough to define "new Date()" as being evaluated on the back end for queries that are executed on the back end. And being evaluated in the vm for queries that have a bound candidateCollection.

But does this satisfy the requirements? Once you have a Date in JDOQL, what can you do with it?

+1. maybe "new Date()" could be the expression where evaluation occurs on the

database.

Quoting Jörg von Frantzius <[EMAIL PROTECTED]>:

Dear experts,

there had been several occasions where in our applications we had to

in the database, and in another we need it for our simple replication
algorithm.

In distributed systems in general it is often crucial for
synchronization purposes to have a common source of time information
that is accessible from all processes.


of the database, e.g. as a JDOQL function.

determine the database server's current time(-stamp). In one application we needed it to synchronize sent JMS messages with visibility of commits It would be great if JDO2 could offer a way of doing that independently
