Thanks.  I had just found that CursorLocation=clUseServe causes the
table to display in index order, but I did not know about the
TableDirect=True requirement.

I am still wondering if this is the best/only solution, since the BCB6
help on "CursorLocation/TADOConnection" seems to indicate some
problems.  It says:

"A server-side cursor offers less flexibility, but may be more
advantageous (or necessary) for large result sets. Using a server-side
cursor becomes necessary when the sheer size of a result set exceeds
the available disk space that would be needed to create the
client-side cursor. Also, many servers only support unidirectional
cursors. This would preclude moving the record pointer in the dataset
backward (even one record) through the result set."
