I am running tkprof on some trace files with the following options:
(Oracle 8.1.7)
explain=<user>/<password> sort=exeqry,fchqry,execu,fchcu
Output after each query includes the following two tables:
Rows Row Source Operation
------- ---------------------------------------------------
36 INLIST ITERATOR
36 TABLE ACCESS BY INDEX ROWID PART_LIST
72 INDEX RANGE SCAN (object id 3451)
Rows Execution Plan
------- ---------------------------------------------------
0 SELECT STATEMENT GOAL: CHOOSE
36 TABLE ACCESS GOAL: ANALYZED (FULL) OF 'PART_LIST'
The "Execution Plan" table corresponds to the Explain Plan section
of the Performance manual. There is no mention, however, of the
"Row Source Operation" table. I note particularly, that in some cases
the first table seems to agree with the second. In others, however, such as
the example here, the Row Source table shows use of an index while the
Execution Plan shows a Table Access (Full table scan?).
Am I interpreting this correctly? If so, what is going on?
Thanks,
