Using ROWID in the ORDER BY clause

Hi,
I can consider myself as a PL/SQL beginner. I need to query some existing tables created for audit scope.
These tables have more duplicate rows respect to the same audit date: the precision is at "hour and minute and second" level.
But I need to understand which is the more recent row for the same audit date. So I think to use in the SELECT statement
the clause ORDER BY in this manner:
SELECT ... FROM Audit_Table ORDER BY Audit_Date desc, ROWID desc.
I'd like to use this ORDER BY also for the ROW_NUMBER function.
Any suggests to me about this topic? Many thanks

I don't need to provide an example, I can do better by pointing you to the documentation:
http://docs.oracle.com/database/121/SQLRF/pseudocolumns008.htm#SQLRF00254
"If you delete a row, then Oracle may reassign its rowid to a new row inserted later" - for example
I can point you to asktom: https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:912210644860
"ROWIDs are NOT sortable" - for example
Your example just happened to work, but you are using the rowid semantically incorrect.

Error : The ORDER BY clause is invalid in views, inline functions, derived

Hi All,
I am on 11g 6.2, Windows Server 2008, my db SQL server 2008, I am facing the error for the reports in which I am trying to edit one the column formula and do something like 'abc/sum(abc)*100'.
10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS.

[nQSError: 16002] Cannot obtain number of columns for the query result. (HY000)
One of the solutions to this which I have found is to edit the EXPRESSION_IN_ORDERBY_SUPPORTED feature in the db properties.
I want to know what does EXPRESSION_IN_ORDERBY_SUPPORTED means?
When I create a calculations in 11g like abc/sum(abc) in the column formula for a column then i get this error.
What does this error mean? Does OBIEE 11g doesn't support using these expressions in the report and the fact that it applies the order by clause to the reports, the report fail?
Could anybody please explain the issue. There is very limited information on this over the web.
Thanks in advance.
Ronny

Thanks svee for the quick response, actually i had resolved the issue by unchecking the EXPRESSION_IN_ORDERBY_SUPPORTED option in the database. I want to understand how does that makes the difference?
What does EXPRESSION_IN_ORDERBY_SUPPORTED mean? Does it mean that if I give any expression in my answers report and since obiee uses a order by for all the queries, the expression won't be supported?
Please explain.

Can I use an expression in order by clause

SELECT
PERIOD_NUM, period_num *12,
period_name,
--TO_DATE(SUBSTR(PERIOD_NAME,1,3)| |SUBSTR(PERIOD_NAME,INSTR(PERIOD_NAME,'-'),3),'MON-RR'),
TO_NUMBER(TO_CHAR(TO_DATE((SUBSTR(PERIOD_NAME,1,3)| |SUBSTR(PERIOD_NAME,INSTR(PERIOD_NAME,'-')+1,2)),'MONRR'),'RRRRMM'))
FROM GL.GL_PERIODS
order by 2--TO_NUMBER(TO_CHAR(TO_DATE(SUBSTR(PERIOD_NAME,1,3)| |SUBSTR(PERIOD_NAME,INSTR(PERIOD_NAME,'-')+1,2),'MONRR'),'RRRRMM'))
desc
gl_periods is a table, period_name consists of values like oct-01_fy-01 etc and oct01_01_fy-01
I want to sort on this column based on period_name, so I am trying to convert into number like for oct-01_fy-01, the query gives
200110 and so on. the recent period comes first, But my question is I can't use the same to_number(.....) in the order by clause. oracle gives an error
ORA-01843: not a valid month.
Let me know whether anyone come across with this kind of situation

If you are sure the expression is correct, since you are using it in the select clause, give an alias and use the alias in the order by clause.

Using bind varaible for order by clause

Hello
Can some one suggest for the following scenario?
My order by clause will be constructed based on the selected fields in the form. And now the order by clause need to be passed as parameter to Excel report.
When I use Ref cursor and OPEN-FOR-USING clause, data is not sorted.
do we have any other alternate for this?
Please observe the example code for the same. Block below resembles the code for to select the data for excel report.

I have already tried to follow this thread below, but no change.
HI
In this specific report ran above the offending sql uses a CTE.
I am on 11.1.1.6.1, Windows Server 2008
Currently in testing phase in migration from 10g.
I know what the error means, just not how to resolve it or what setting may be causing this.

In Physical layer, go to specific database(Physical layer's) properties, database features tab -> Un check the EXPRESSION_IN_ORDERBY_SUPPORTED.
For that failed report, go to Answers-> advance tab-> Look for 'Advanced SQL Clauses'
Check this box to issue an explicit Select Distinct
Let me know updates

How to change the order by clause of a standard VO in OAF

Hi All,
I need to change only the order by clause of a standard VO (Which is attached to a messageChoice item).
Steps followed:
1)Created a custom VO by extending the standard VO .
2)VO Impl class files are not generated as seeded VO has no such class files.
3)Created a substitution
4)Imported it
5)When I try access the specific page, getting Sys Admin error without any clue about the error.
Even I tried to create the custom VO without extending the std VO ,
Still getting the same error .
Please provide your suggestions on this.
Thanks,
Thavam

When I set the FND:Diagnostics profile option , I could see what was the exact error . It was SQL Wrapper exception error.
The VO which is extended , has a dynamic where clause with bind variables. The binding style of the extended VO does not match with seeded VO. It works when the binding style is changed.
Thanks,
Thavam

Using ROWID in the WHERE clause of a SELECT statement

hi all,
my team is trying to select a value from a table using the rowid as the selection criterion
e.g. select column_name from table_name where rowid > 'AAA112BBBCCC12A'
this query does not appear to return accurate results e.g. it return rows instead of two. my questions are:
1. is this a legitimate approach?
2. should we convert the row id to varchar2? if so how should this be done?
thanks!

7 rows selected.1) using rowid to access a record is the quickest way so it is legitimate
however using > has no real purpose as you point out you cannot get any meaningful results returned.
2) No real need to convert however beware storing values in tables as Oracle does not guarantee to preserve the format in different versions so upgrading from 9i to 10g would invalidate your data.

Sorting technique used by oracle for "order by" clause.

Hi All,
it could be very help to me if you provide some information about sorting technique used by oracle engine for order by clause.
Issue i am facing :
Table : xx
Line Date
1 05-06-2013 00:00:00
2 05-06-2013 00:00:00
when we query above table using order by date, it is returning line 2 prior to line 1. we would like to know why it is returning line 2 first?
Regards,
Ram

Well ok - but be warned that many people wind up being sorry they ask that question. Hopefully Hemant's answer is what you really wanted.
See 'Linguistic Sorting and String Searching' in the Oracle® Database Globalization Support Guide
http://docs.oracle.com/cd/B28359_01/server.111/b28298/ch5lingsort.htm
Sorting will be controlled by the settings of NLS_LANGUAGE, NLS_SORT and NLS_COMP.
Here is the doc page for NLS_SORT
http://docs.oracle.com/cd/B28359_01/server.111/b28298/ch3globenv.htm#i1008393
>
NLS_SORT specifies the type of sort for character data. It overrides the default value that is derived from NLS_LANGUAGE.
NLS_SORT contains either of the following values:
NLS_SORT = BINARY | sort_name
BINARY specifies a binary sort. sort_name specifies a linguistic sort sequence.
>
And the one for NLS_COMP
http://docs.oracle.com/cd/B28359_01/server.111/b28298/ch3globenv.htm#i1008458
>
The value of NLS_COMP affects the comparison behavior of SQL operations.
You can use NLS_COMP to avoid the cumbersome process of using the NLSSORT function in SQL statements when you want to perform a linguistic comparison instead of a binary comparison. When NLS_COMP is set to LINGUISTIC, SQL operations perform a linguistic comparison based on the value of NLS_SORT. A setting of ANSI is for backward compatibility; in general, you should set NLS_COMP to LINGUISTIC when you want to perform a linguistic comparison.

Help Urgent! RowIterator retrieval doesn't respect the order by clause.

Hi,
Jdev 10.2.2
I'm using the RowIterator (source iterator) through a defined association to create rows in a destination RowIterator.
The creation of those rows must respect the order clause defined for the ViewObject => source Iterator.
I noticed that when I retrieve the rows through the RowIterator, the order clause is not respected?
Example of implementation:
Pre-defined weight levels for a postal tariff:
Product A:
From weight To weight
0 - 10
10 - 20
The user will have enter a price for each level.
I pre-create those rows so that only the price will have to be entered.
As you see the order of display/creation is important.
I there a way to make the RowIterator respect the Order Clause defined for the ViewObject?
I am a bit worried, please tell it's not the default behaviour!
Thanks
Frederic
For info my code:
RowIterator deliveryWeightIt = weightGroupImpl.getDeliveryWeightAssoc(); // source rows
if (deliveryWeightIt == null)
throw new JboException(getClass().getName()+".setWeightGroupId Detail row generation,. System error. DeliveryWeightAssoc is null.");
deliveryWeightIt.first();
Row currentDeliveryRow = deliveryWeightIt.getCurrentRow();
Row newPostalDetail = null;
try
while (currentDeliveryRow != null)
newPostalDetail = postalDetailIt.createRow();
SequenceImpl s = new SequenceImpl("SITE_POSTAL_REL_SEQ", getDBTransaction());
Number newSeq = s.getSequenceNumber();
System.out.println("numberOfGeneratedRows: "+numberOfGeneratedRows+", newSeq: "+newSeq+", FROMWEIGHT: "+currentDeliveryRow.getAttribute(DeliveryWeightImpl.FROMWEIGHT)); newPostalDetail.setAttribute(PostalDetailImpl.FROMWEIGHT,currentDeliveryRow.getAttribute(DeliveryWeightImpl.FROMWEIGHT));
newPostalDetail.setAttribute(PostalDetailImpl.TOWEIGHT,currentDeliveryRow.getAttribute(DeliveryWeightImpl.TOWEIGHT));
postalDetailIt.insertRow(newPostalDetail);
numberOfGeneratedRows++;
currentDeliveryRow = deliveryWeightIt.next();

Ok I think I found my mystake.
I was using the entity association instead of using a view link.
I avoid using links because I encountered Class Cast exception => similar to thread 10.1.2: view Link accessors in entity object return ViewRow ??????
Will there be patch available soon?

How can you make photobook using photos in the order you have them titled

I spent a lot of time renaming photos ("a1" through "z9") to get them in chrono order when viewing/sorting them by title. Yet, when I go in to create a photobook it doesn't put them in this new order by title, but rather uses the old naming system which puts them out of order. Anyone have any ideas how to get photobook to look at the photos by "new" renamed title?

I put them in chrono order after all all were imported into iPhoto by naming them appropriately.
No, that puts them in alphabetifcal order, not chronological order.
What other post?
I started to repy to this post earlier and somehow aborted the post instead of adding it.
If you use the Batch Change ➙ Date option with 1 minuted between photos on the photos as they are sorted by title they will go into the book in that order.

Column Security - Users can't see it, but need to use it in the query WHERE Clause

I am looking at possible solutions (if any) on column security. We need to be able to restrict users from seeing certain columns, however, they will need these columns in the WHERE clause of queries.
I thought about creating views, however, it would be a poor database design. Is there any way that this can be done on the database level. I know about Fine Granular Access Method, however, this just excludes the column completely. Which means that they can not be used in the WHERE clause.
Any help would be greatly appreciated.

I too added 2nd apple ID when I tried to get Free app from apple store just to get to NONE on the credit card needed. It said it sent confirmation email to my new apple ID email that I have to confirm. Problem is I can not get to the new apple ID email account. On my ipad it logs into my original email account and I see no where to log into another email account. If I go to my laptop, the new apple ID I created does not let me log into email where apple said it was sent to. It did not send to back up email account either.
Can I log into 2 email accounts on my ipad where it says mail at bottom?
Can I have 2 apple ids?
If I created a 2nd apple id to get to NONE on credit card needed, can't I log into it also on another laptop in gmail?
(won't let me)
If I used my original apple id I created when I got my new ipad, it will not let me get free app without credit card, there is no where it says NONE needed. I am too new to apple to start with credit cards etc until I get use to it.

Where do I use flash in the order of things?

So I am making an animated DVD menu. I want to be able to

show up automatically in Encore. Do I do this all in Flash? Or do I
do something in Photoshop first? Also should I use actionscript 1,
2 or 3? Not really sure of the differences.

Hi, Parthabe.
Yes, I've seen this list. I suposse which one is my problem (because in the response, they didn't give me the ID), but I can't see more than the description of the problem, without solution . What do I have to do with this list? I feel so clumsy
I use LabView 8.5.
I think this is the list, or not?

Which clause is overridden by the ORDER By clause

1. group by
2. having
3. select
4. where
5. from

It implies that distinct, group by guarantees a
sorted order. I have seen Tom Kyte disprove this lots
of time....and 10.2 (in particular the hash group by) is going to screw up a lot of people who have mistakenly relied on this.

Materialized view and Order by clause

Hi all. I'd like to have some information regarding the order by clause used in a materialized view.
I'm using Oracle 9.2 and Win2003 server. I have a common view (my_common_view) on which a materialized view is based (my_materialized_view). Materialized view is built for fast refresh and is created in this way:
create materialized view my_materialized_view as
select * from my_common_view
order by 1,2,3;
My question is: if I query this materialized view without adding an order by clause in the statement, I will obtain always an ordered result set? So, is it useful to include the order by clause in the materialized view script or the order by has to be include in the statement used for quering the materialized view (for example like this: select * from my_materialized view order by ...)?
Thank you very much.
Ste.
