Are you adding an global index to a partitioned table?

I don't believe the specific table stats are affected.  Possibly if you specify "COMPUTE STATISTICS" on the crate index statement


It should be simple enough to test:
create a table.
compute statistics.
look at the last_analyzed column for the table
wait a minute or three.
add you index
look at the last_analyzed column for the table

Analyze table is deprecated and really shouldn't be used any more.

The DBMS_STATS package is the new way of doing things.

Anyway, the online documentation will tell you what all is performed with the various options the commands offer.

Again, set up a quick test and see the commands in action.
