RE: TEMPORARY TABLES

Peter,

The tables are "permanent" but the data within them is temporary - the data life is either until you commit or until you logoff depending upon the option chosen when you create the table.

This is initially confusing as it is different to how (say) Rdb handles temporary tables.

Somewhat related, if you look at locks, you will see locks held on these tables until you either commit (for on commit delete) or until you truncate the table (for on commit preserve).

HTH,

Hi

I am working on some development here and have decided to use temporary tables to do some work as they seemed to be the best way to acheive what I wanted and the data is only required for the sesion.

I seem to be experiencing a problem where the only way the temporary tables are removed is by actually dropping them or by bouncing the database.

I thought that they were supposed to be session specific or program module specific.

Perhaps I misundestood the docs

I am creating them as follows

v_CreateString := 'CREATE GLOBAL TEMPORARY TABLE t_tmp_cal1 ( part NUMBER, readings NUMBER) ON COMMIT PRESERVE ROWS'; EXECUTE IMMEDIATE v_CreateString;
and
v_CreateString := 'CREATE GLOBAL TEMPORARY TABLE t_tmp_cal2 ( part NUMBER) ON COMMIT DELETE ROWS';
EXECUTE IMMEDIATE v_CreateString;

Oracle8i Enterprise Edition Release 8.1.7.0.0 - Production

I have looked at metalink and found nothing specific to point the way Any help appreciated
