Bitmap Indexgreenspun.com : LUSENET : DBAzine : One Thread
I want some more information/concept on bitmap indexes.
1. I have 2 K rows in table 2. One column Sex with only 2 values M and F
I know oracle creates bitmap for above values which directly points to rows.
How oracle creates bitmap for each row ?
how many bits will be required , so that they can point to only one row in table ?
Thanks for your time
