Re: Indexes used by sql

[Charles Wilt <charles.wilt@xxxxxxxxx>]

If you're on a supported release, ie. v5r4 or later, the last used
date of the *FILE object is updated when it is used by the query
engine to satisfy a query.

Note however, that an index may provide statistics useful to the query
engine even if not used direct to satisfy a query.

iNav gives last date and time used for both purposes...see
