I know the only way to guarantee a specific sort order result when querying table is by using the order by clause. However, I have an issue where I do not have access to the code for the web user interface of a very lightly used interface (has two users). In that user interface is a drop down box that is populated by a table - one table. The drop down box is populated by the query "select [column name] from [table name]". Right now there are 400+ rows in that table total, so it's small but not having the items ordered is a pain.
I would like to alter something on the db side so the result of "select [column name] from [table name]" is an ordering by the column descending. I don't want the sort order to be the same for all queries (including joins and all) just want to control the order for that one query. It is Oracle9i.
I have data that i am sorting, the data is mostly numeric (format of XXX-1234). is there any way to have my query sort xxx-1000 AFTER xxx-999? right now i am thinking i will have to create a separate sort order column on my table.

i.e.:

View 2 Replies View RelatedWhich step in the following plan is the first step of execution
I reckon it is "TABLE ACCESS BY INDEX ROWID| BANK_BATCH_STATE"
Is that correct?
In the "Predicate Information (identified by operation id):"
section the predicates - access and filter for the step "TABLE ACCESS FULL | PYMNT_DUES" are displayed first
Isn't there any relation between the order of execution steps and the order in which predicates are displayed?

I have below tables,
describe rpthead
Name Null Type
--------------------------- -------- -------------
RPTNO NOT NULL NUMBER
RPTDATE NOT NULL DATE
RPTD_BY NOT NULL VARCHAR2(25)
PRODUCT_ID NOT NULL NUMBER
describe rptbody
Name Null Type
------------- -------- -------------
RPTNO NOT NULL NUMBER
LINENO NOT NULL NUMBER
COMMENTS VARCHAR2(240)
UPD_DATE DATE
The fact is that we store some header in RPTHEAD and store real data in RPTBODY, the question is that if I use below SQL to query all data for a 'PRODUCT_ID'.
SELECT t0.LINENO, t0.COMMENTS, t0.RPTNO, t0.UPD_DATE
FROM RPTBODY t0 , RPTHEAD rpthead
WHERE
(
t0.RPTNO = rpthead.RPTNO
AND
t0.UPD_DATE>=to_date('1970/01/01 00:00:00','YYYY/MM/DD hh24:mi:ss')
AND
rpthead.PRODUCT_ID IN ('4647')
)
I do not want to have 'ORDER by' clause since data set is too large, the sorting takes long time, is there any way to get the result rows in the order sorted by RPTNO? We have the index for RPTNO on RPTBODY.
I've got one database which was Initially upgraded from Oracle 8i to 10.2.04 running on windows. Most of the tabespaces are Dictionary managed. Do you think moving them to locally managed tablespace would give me better performance?
if Yes, what approach I should apply to move them to locally managed? I would like to do this with minimum/no downtime.
Question 1) I have read the following statement in a PL/SQL book.
Quote:To check whether an existing procedure is compiled for native execution or not, you can query the following data dictionary views:
[USER | ALL | DBA]_STORED_SETTINGS
[USER | ALL | DBA ]_PLSQL_OBJECTS
However, I when i query the view USER_PLSQL_OBJECTS I get the following error message:
Quote:ORA-00942: table or view does not exist
Question 2) I have read the PLSQL_WARNING can be set to DEFERRED at the system level. However, I am unable to defer it. tell me how to apply defer caluse to following statement:
Quote:ALTER SYSTEM SET PLSQL_WARNINGS ='DISABLE:ALL'
can i modify oracle data dictionary

Different error and that syntax, as far as I can tell, is sound - error message be damned.
An example of a query working on both versions is

sum(salary)
from

group by grouping sets ((employee_id),null)

Am I missing something? Does grouping sets not work over the dictionary views?

In order to improve the performance of our live server, I am trying to do an exhaustive comparison with our test environment which is quite quick in spite of the fact that we port the data from Live every month.
There are no obviously slow queries appearing in the the top SQLs of AWR, we have optimised such things already. Right now it is about general uplift rather than SQL based tuning.
I picked up random SQLs and I noticed a marked differences in the execution time. Typically they are 3 to 4 times and there are cases much more than that.
1. I observed that, while the explain plan of the queries are same, trace of the queries give a different picture. I have observed that the recursive calls, consistent gets and sorts(memory) are quite high on Live.
2. I have no solid reasons to say this but my instincts tell me that the recursive calls is the major contributing factor. It is sometimes 2000+ for an SQL.
3. On googling more on that, it finally made me compare the data dictionary on the AWR report of test and Live.
The dc_objects caught my eyes. In that 4 hour AWR, there were about 10 million get requests and the pct miss was ~10. For similar load, the test server had 5 million gets with 0.08 PCT miss for 4 hours.
