Statistics 0 recursive calls 0 db block gets 4 consistent gets 0 physical reads 0 redo size 866 bytes sent via SQL*Net to client 503 bytes received via SQL*Net from client 2 SQL*Net roundtrips to/from client 0 sorts (memory) 0 sorts (disk) 3 rows processedQusetion: From where is it getting information like 'consistent gets', 'physical reads', 'recursive calls '? Or is it calculated from views like v$sysstat, etc.?
I've never seen the code that SQL*Plus uses when you turn autotracing on. My guess is that SQL*Plus is querying from V$SESSTAT. I arrive at this guess since before you can set autotrace on, you must first run the $ORACLE_HOME/sqlplus/admin/plustrce.sql script. And this script grants SELECT privs on this view.
