Searching no-unique data chunks by index

 I want to be able to return only a segment of the rows based on a non-primary non unique key. I want to be able to go forwards or backwards based on the key keeping the position between sessions. This is a huge table so "scrolling" is necessary. I have considered a composite index which is made of of a unique field + the PK but cannot seem to retreive based on this index starting on a key. Is it possible to reteive the data in this form? Received on Mon Aug 23 1999 - 13:25:09 CDT
