Does it automatically reconnect? That certainly seems like the wrong thing

got that from the MySql doc it can be set up to reconnect if ping fails

Ah, so Oracle still requires an actual table? Thought they might
have joined the rest of us by now in allowing things like
'SELECT 2+2;' :)
No, it always requires a FROM clause, which is typically `FROM dual` for stuff

Just to reiterate what I eventually said. I don't want ping changed in
DBD::Oracle.
All I was saying is you should only read anything useful into ping returning
false and not true unless your only purpose is like
betweeen all DBDs then no again and I am
sure H.Merijn would like that.
An option would be nice as well

I would tend to think that such a ping would be a special case, but I agree
with you to keep it as is:
Simply because overloading ping() with a complete eval'ed select statement
would be trivial. And the opposite isn't.

I rather strongly disagree. It is possible to do useful work over a
connection in situations when a 'simple select' is not possible.
My production Oracle database is protected by a physical standby database.
Ah, well in that case I
