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;
