Hi,

I am finding some surprising results with indexing.

If I have a select with several fields, and do a where id = 1, and I only
have id indexed, it does not seem to help the query at all.  I would have
thought SAP would use the id index to avoid a table scan, and just select
the fields from the rows where id=1.  But this does not seem to happen!

Can anybody please explain why?!

It only seems to help if we have all the fields were are selecting in a
multi-field index.

Many thanks,

David
