Home -> Community -> Mailing Lists -> Oracle-L -> RE: BITMAP Versus B-TREE
Do you mean the column has only one value, including nulls? I wouldn't put
an index on that.
Yes, bitmaps are great for queries but a pain for loading. They can also
really favour certain access paths and I find a little "buggier". They can
also grow like crazy.
I would say, if you heavily use bitmaps, it increases your administration.
Like all things oracle, it's the details that kill you.
