His usage suggests he should be using a regular table, possibly with
some kind of clean up / setup user defined functions associated with it.

The whole idea of temporary tables is that they allow you to write a
single client that declares a single table by name, and then you can run
that client any number of times, and each will not interfere with the
other.  Generally, trying to share temp tables across different backends
is a bad idea, since the original session that created it might exit and
it would cease to be.

Anjan,

I would be very interested in this feature as well.  However, my understanding is that you must keep the connection open AND your application must retain the SAME connection between database interactions. 

The only way that I have done this is by creating a  Session ID column to your table of interest and make it a permanent table. The application then maintains the Session ID in memory and uses it to segregate the data from various users.

My main interest in this is to create my own user table which triggers on other tables will somehow use to know that a specific user is making a change on a specific row(s).

How do others handle this issue?

Enthusiastically,

Dave Leedom

A developer is trying to use a Temporary Table via the java based application. The problem is following the temp table creation, he wants subsequent queries to query the temp table, but they are not in the same database session as the temp table. Is this something I can setup somewhere in the config? I would appreciate any pointers/info I can forward to him.
 
Thanks,
Anjan
