Subj: | | Filter condition in a Join Index |
|
From: | | Tarun Neelam |
What are the concerns of having a filter criteria when creating a single table join index. I am in situation where in I need to process
50% of a 8 billion row table I was thinking of 2 options one inserting rows into another table based on the filter criteria & then
process the data or second create a single table join index with same filter criteria so that when I execute the query on the base table
the optimizer will make use of join index. I am basically looking for an efficient way of process the data. Can someone throw some light on
this.
