Hi Marc,
When you were here in London
we'd discussed adding functionality to use things like ROWID for fast updates
and deletes [as opposed to using primary keys]. I have been able to implement
this by
1. Adding a field in jaws.xml called rowid-column
name. This is ROWID for Oracle and
Hi,
This looks very interesting. I'm kind of too lazy to read your code to
find out the answer for myself...
My impression is that Oracle ROWID and similar facilities such as
Interbase/firebird dbkey are stable only within a transaction, and in fact
expected to change with any update. Could you
I'll get this patch in later today.

Ok,
I've changed the JDBCCreateEntityCommand as
public JDBCCreateEntityCommand(JDBCCommandFactory factory)
{
super(factory, "Create");
beanExistsCommand = factory.createBeanExistsCommand();
// Insert SQL
String sql = "INSERT INTO " + jawsEntity.getTableName();
So do you build all your other applications to use rowid?

I think unified diffs are the most convenient to use. If you're on W2k (I

What
I tried to send this out earlier today, but it never showed up (trouble
on my end)
The reason I was suggesting an oracle specific option name was because I
really think that we need to use the Oracle specific syntax to return
the rowid value on inserts.

Oops, I forgot about that. But Vinay is right, a stable ROWID
might be present in several other da

My views. Your thoughts?
