Event 10053 - Dump Optimizer Decisions

Event 10060 - Dump Predicates

This event can be used to force the optimizer to dump predicates to a table It is available in Oracle 7.1.3 and above, and was still working in Oracle 9.2.

This event requires the following table to be created in the schema of the user parsing the statement

CREATE TABLE kkoipt_table

(

c1 INTEGER,

c2 VARCHAR2(80)

);

To enable this event use

ALTER SESSION SET EVENTS

'10060 trace name context forever, level 1';

This example uses the following object

CREATE TABLE t1 (c01 NUMBER, c02 NUMBER);

With event 10060 set to level 1, when the following statement is executed for the first time

SELECT c01 FROM t1 WHERE c02 = 0;

It is parsed and the results written to kkoipt_table

The results can be selected using the statement

SELECT c1,c2 FROM kkoipt_table ORDER BY c1;

The following table summarises the various operations that can be reported by this event

Operation	Description
fptconst	Folding constants
fptrnum	Remove ROWNUM predicates
fptwhr	Remove all WHERE predicates except remaining ROWNUM predicates
frofkks (rowid lookup)	ROWID lookup
frofkks[i] (and-equal lookup)	start key
frofkke[i] (and-equal lookup)	end key
froiand	index-only predicate
frofkksm[i] (sort-merge)	sort-merge key
frosand (sort-merge)	sort-merge predicates
frojand (sort-merge)	join predicates
frofkks[i] (index start key)	index start key
frofkke[i] (index stop key)	index end key
frofand (hash part)	table predicate (hash)
froiand (index only filter)	index only predicate
frofand	table predicate
froutand	outer join predicates
