Answer 1

Here is a small example how this could be done (assuming CDATE is a index on TEST table):
SQL> connect admin/admin
Connected.
SQL> create table test(x int, y varchar2(10));
Table created.
SQL> create index cdate on test(y);
Index created.
SQL> connect / as sysdba
Connected.
SQL> exec dbms_stats.gather_table_stats(ownname=>'ADMIN', tabname=>'TEST', cascade=>TRUE);
PL/SQL procedure successfully completed.
SQL> connect admin/admin
Connected.
SQL> select table_name, last_analyzed from user_tables;
TABLE_NAME                     LAST_ANA
TEST                           26/07/11
SQL> select index_name, last_analyzed from user_indexes;
INDEX_NAME                     LAST_ANA
CDATE                          26/07/11Edited by: P. Forstmann on 26 juil. 2011 13:46
