Question

As the title says, in an Oracle 10g database, I’d like to create a query that will generate a set of ANALYZE INDEX commands for every index owned by a certain user. I’m a complete layman when it comes to database topics, so please keep answers as dummy-proof as possible, thanks!

Answer 1

As you’re on Oracle 10g you really ought to be using DBMS_STATS instead. That could be implemented as simply as …

begin
    for r in ( select index_name from user_indexes )
    loop
        dbms_stats.gather_index_stats(user, r.index_name);
    end loop;
end;

There are other parameters: check out the documentation.

If you want to generate stats for some other user’s indexes use ALL_INDEXES instead, and restrict on OWNER.

If your heart is set on ANALYZE then

spool anl_idx.sql

select 'analyze index '||&&owner||'.'||index_name||' compute statistics;'
from all_indexes
where owner = '&&owner';

spool off
