Re: Papers on Partition Elimination?

I'm speaking from experience using 7.3.x partition views, which are not nearly as clean as 8.0.x partitioning (not that 8.0 is clean!). There are quite a few requirements to make this all work. See the Oracle 8.0.x on-line documentation, under Server Concepts, Chapter 8: Partitioned Tables and Indexes, and Server Tunining, Partitions: http://www.eng2.uconn.edu/~orasun/doc/server803/index.htm

If 8 partitioned tables are anything like 7.3.4 partition views, in order for partition elimination to work, your tables have to be analyzed. Your query may have to have the value hard-coded (rather than using bind variables) to restrict the partitioned column to a subset of the partitions. Even then, you have to look at the explain plan to really know if it's all working correctly.
