It would only be missed if you didn't report your results and included a spreadsheet and a graph! :)

Mike,
If I was to look at this from a totally Logical stand point - I would think the Indexes are ONLY update if you update a field in a record where that field is contained in one or more of the Indices.
However, Why not do a simple test - and generate your Own answer!??
Take a chunk of the data from your table in question - or even take a copy of the Whole thing, along with the Indices, drop into another folder. Then - simply do some updates based upon your criteria below - and then you can confirm Exactly what happens!
Right???
:-)
-K-
But if I did that, think of the discussion and thread that would be missed here. LOL
This question relates to VFP CDX files but is something in theory too for other systems (although I realize they may do things differently).
I just dropped a boatload of nonsense indexes from a client's legacy app database and believe that it (theoretically) should improve network traffic by lessening these unneeded updates.
