Hi all,
I'm trying to set up stored outlines and am running into the following problem (OUTLN tables are initially empty and the shared pool has just been flushed):
ALTER SESSION SET CREATE_STORED_OUTLINES = TRUE;
SELECT 'THISISMYTEST' FROM DUAL;
ALTER SESSION SET CREATE_STORED_OUTLINES = FALSE;
SQL> SELECT HASH_VALUE,SQL_TEXT FROM OUTLN.OL$;
HASH_VALUE SQL_TEXT ---------- ------------------------------------------------------------ 1024768383 SELECT 'THISISMYTEST' FROM DUAL
SQL> SELECT HASH_VALUE,SQL_TEXT FROM V$SQL WHERE SQL_TEXT LIKE '%THISISMYTEST%';
HASH_VALUE SQL_TEXT
---------- ------------------------------------------------------------
2081312514 SELECT 'THISISMYTEST' FROM DUAL
2452395670 SELECT HASH_VALUE,SQL_TEXT FROM V$SQL WHERE SQL_TEXT LIKE '%
THISISMYTEST%'Now (as expected) there is now one row in OUTLN.OL$ but the HASH_VALUE != the HASH_VALUE for the given SELECT statement in v$sql. In fact the HASH_VALUE doesn't match anything in v$sql.
Obviously (and demonstratively) the outline will not be used if the query hashes to a different value that the outline. Am I missing something? (CREATE ANY OUTLINE is granted)
Thanks for any help, - Bill.
