Question: if everything (each column) from the resultset of the original index-utilization qry
if all columns to the right of has_filter are NULLs -- does it means that the index IS NOT USED AT ALL?
also, why database id and object id would be NULL ? table listed in col 1, index name in col 3 of the result-set -- so why db id and obj id would be nulls, really?
THANK YOU SO MUCH in advance for possible dispersing of my doubts and confusions...
