- Informix provides very useful tools for estimating sizes of rows in
- a table. Perhaps I've overlooked it, but I can find nothing about
- estimating sizes for indexes. In other words, given table X with
- indexes A, B, and C, how much overhead is required for each additional
- row in table X?
-
- Can this be done easily? Is there somewhere in the documentation where
- this is covered? Is there any difference in overhead for SE and Online
- (unfortunately, we have to support both)?
-
- TnxInAdvance.
