David, For ease of tablespace management and backups we created tables based on the year. ex: tab_curr, hist99,hist01,etc and then created a view that selected from each table with a union. Then the developers could select from the view and not be concerned with the actual table name. As each year was added to the view the past year was made READ ONLY and archived. This made backups simpler and faster. The major drawback that I found was the index on the underlying tables was not used when you select through the view. Partitioning of the tables made it easier and was well worth the expense. When you create the partitioned tablespaces make it easier on your self by creating a few future partitions but smaller in size. Then as time rolls forward and you need to start using the next partition you can increate the size to accomidate the projected information. The MAX partition has to be created but can be minimal if you plan on checking for entries ocassionally(future data can get entered at times). Creating future partitions is a lot easier that splitting a partition. Ron
>>> [EMAIL PROTECTED] 11/20/02 03:38PM >>> David, You're talking about Partitioned Views, which was the predecessor of partitioned tables. This was the drawback of partitioned views - you had to insert into the individual tables. You can make a sql*loader script figure out which table to insert into (if you're using sql*loader). Otherwise you might what to try writing a procedure. If you have any problems with partitioned views, expect Oracle Support to tell that you should be using partitioned tables.

Communications Ephrata, PA USA >>> [EMAIL PROTECTED] 11/20/02 01:48PM >>> Hi Guys I'm trying to see if I can get around paying oracle $50,000 for partitioning I have a huge table and I want to partition it on date so I created 12 tables AAAA_JAN AAAA_FEB And so on But I want to create a view that will be used for inserting so it always Points to the current month without having to recreate the view every month. Is there anyway anybody can think of doing this?
