Order by AND rownum in a function?

I have a table with articles sorted by an id. In the table is also a date field to tell when the article is written.
I want a query that returns the 20 latest articles, and this is what i have come up with:
SELECT * FROM (
SELECT articleid,writtendate
FROM articles
ORDER BY writtendate desc)
WHERE ROWNUM < 21;
This works alright, BUT I want it in a function! There it doesnt compile!!! Anyone got any suggestions?
I have tried to separate the stuff, like first sorting the records in a view and then selecting the top 20 after that. I could try a cursor and fetching out of that, but havent suceeded with that either.
Bye!

ok, the sql statement works perfectly in an sql editor, but wont compile in a function.
FUNCTION fnc_getLatest20 (
cur IN OUT pkg_cursor.refcur
)RETURN pkg_exception.return_type IS
BEGIN
OPEN cur FOR
SELECT * FROM (
SELECT articleid,writtendate
FROM articles
ORDER BY writtendate DESC)
WHERE ROWNUM < 21;
RETURN pkg_exception.err_none;
END;
The best I have is that either the rows returned in the cursor is all rows, ordered correctly or the top twenty in some other order.
I most be on the wrong track here, there has to be some easier way of doing this...
BTW, thanks for the help so far.

Using order by and rownum in massive tables

Hi,
I need to retreive paginated and ordered data from a big table.
I know some different tips using rownum or the RANK() function and subqueries, these tips work well for small amount of data, but I need to get the data from a table with 200.000 entries (not under my control), and with all those methods is necessary to order first the data and then select your range, so performance is extremely poor.
Anybody knows a better solution? it doesn't matter if is plain SQL(better) or PL/SQL.
Thanks in advance

but I was looking for something like the LIMIT in MySQL or TOP in msSQL where all the sorting is made internally and it's really fast If the data needs sorting, I do not think Oracle would take any longer to do that than the others mentioned, unless the other DBs mentioned, only sort the rows that are actually being returned.
As for the LIMIT clause, Oracle already has that clause available when FETCHing from a CURSOR:
SQL> DECLARE
2      CURSOR emp_cur IS
3          SELECT * FROM scott.emp;
4      TYPE emp_rec_table IS TABLE OF emp_cur%ROWTYPE INDEX BY BINARY_INTEGER;
5      emp_tbl emp_rec_table;
6 BEGIN
7      OPEN emp_cur;
8      LOOP
9          emp_tbl.DELETE;
10          FETCH emp_cur BULK COLLECT
11              INTO emp_tbl LIMIT 5;
12          EXIT WHEN emp_tbl.COUNT <= 0;
13          dbms_output.put_line(emp_tbl.COUNT || ' rows fetched using LIMIT clause.');
14      END LOOP;
15      CLOSE emp_cur;
16 END;

Question about order by and rownum and subqueries.

Can you explain why test 4 below results as it results- with returning no rows?
Identificator "PKG_INTRA_CUSTOMER_SEARCH.NAME" is a package function, which returns value from a variable declared in package body, the function returns value 'e%'.
Please note that tests 1-3 all returned data, but test 4 didn't. Why? My porpouse is that test 4 would also return data.

Hi,
please reproduce the question in your test database with script below.
My general question is that wht Test5 below returns only 1 row, but Test5 returns 3 rows.
The difference between those two tests is only that one has "order by" clause, the other doesn't have.
I need the "order by" clause to stay, but seems like it is not allowed.

Do you know the link between the sales order item and functional location ?

How know the functional location if I know de sales order number and item ?
Wich table or bapi ?
Tks.

Hi,
I think there's all details in my question.
You answer is right only if I need to know the functional location at AUFNR level.
Is not my case, I need this information at sales order level.

Trouble with subquery and rownum and ordering

I'm having trouble making this subquery work. The basic idea is that the web app will show only so many rows of results on the page, but right now I'm just playing around in SQL*Plus. The address book holds mixed case, so in order to sort by name properly I need to use UPPER to ignore case sensitivity. This SQL statement works fine for me:
select addressbookid from addressbook where addressbookid like '905430931|%' order by upper(addressbookid);I know that if you mention ROWNUM in the WHERE clause, you're referring to the row numbers of the ResultSet that Oracle returns. How do I use both ORDER BY UPPER(ADDRESSBOOKID) and WHERE ROWNUM > 25 AND ROWNUM <= 50? I figured a subquery would do it, but I can't write a correct one that does it! Below are my 2 attempts with the errors, and then I just tried to play with rownum:
SQL> select addressbookid from addressbook where addressbookid in (select addressbookid from address book where addressbookid like '905430931|%' order by upper(addressbookid));
select addressbookid from addressbook where addressbookid in (select addressbookid from addressbook
ERROR at line 1:
ORA-00907: missing right parenthesis
SQL> select addressbookid from addressbook where addressbookid in upper(select addressbookid from addressbook where addressbookid like '905430931|%');
select addressbookid from addressbook where addressbookid in upper(select addressbookid from address
ERROR at line 1:
ORA-00936: missing expression
SQL> select addressbookid from addressbook where addressbookid like '905430931|%' and rownum > 25 and rownum <= 50 order by upper(addressbookid);
no rows selected
SQL> select addressbookid from addressbook where addressbookid like '905430931|%' and rownum > 25 and rownum <= 50;
no rows selectedLike I said, if I can get a working subquery, then I'd like to attach that restriction on the rownum stuff. I'm wondering if it will be a problem trying to get the ordering to happen and then the rownum restriction after that, and all in the same query...
Btw, we've made all the table and column names in our database uppercase, so that shouldn't matter.

This is probably the most efficient way ...
select addressbookid
from
   select addressbookid,
   rownum rn
   from
      select addressbookid
      from addressbook
      where addressbookid like '905430931|%'
      order by addressbookid
   where rownum <= 50
where rn > 25

Order by before rownum

I am trying to select top 200 records from a really complex select query with order by. But Oracle does top 200 first then order by if I put rownum and order by in one select query, which will give me top 200 records redomly every time. I know a way to work around is doing following
select * from (select................ order by ......) where rownum<=200
but this will really take long time since the inner select query is big one. it joins 15 some tables to get all informations. I know in MS SQL, you can have select top(200)...... ordery by ...., it will do order by then top 200. This is making query running really fast.
Is there other ways to make this run faster in Oracle. Possiblely puting oder by and rownum<200 in one select query?
Thanks!

Hi,
See these threads for the information you need to post when you have a performace issue:
When your query takes too long ...
HOW TO: Post a SQL statement tuning request - template posting
If you have a complicated query involving 15 tables, the solution is likely to be complicated, too. For example, you might need to find the top 200 rows before joining all the tables, so just looking for an alternative to ROWNUM probably won't help all by itself, though it may be part of the overall solution.
One alternative to ROWNUM is the analytic ROW_NUMBER function:
SELECT *
FROM     (
         SELECT ...
         ,         ROW_NUMBER () OVER (ORDER BY ...)     AS r_num
         FROM    ...
WHERE     r_num     <= 200
;It might not be faster than ROWNUM, but it's probably not slower, either, and it can be adapted to other requirements (e.g., the top 200 for each department).

Sales Order Material and its MOQ mass change

*The issue is related to our Spare parts Ordering process in our company.*
We have a concept of having 65 days of back orders. Hence there will be
lot many open orders in the system.
The Material code will be changed from (for eg) M01 to M02. Hence forth the Material (M01) ordered will
automatically changed to M02 through Material determination logic. But
for the 65 days back orders, it is very difficult to change the
material one by one in sales order. There may be more than 100 orders
for a material. Even if the MASS change option in Transaction VA05
doesn't address because of the following reasons;
1. The changed new material (M02) may have new price with new validity
periods, whereas the back orders will have old pricing dates. Its
difficult to change individually in the open orders.
2. Some materials may have partially delivered.
Similar to ECM changes, there will be MOQ changes which also needs to
be changed individually the order quantity in the old Open orders.
For example,
Initially the MOQ for a material in 10. Order inflow has happened based
on this MOQ.
Now if the MOQ is changed to 20, future orders are addressed. But for
the 65 day back orders, we need to manually open the individual sales
order and change the order quantity.
Hence we require a mass change option for the open orders as below:
1. For Material Changes (M01 to M02), I will give the list of orders and
the line items and Qty for M01. The program should reject the existing
line item for M01. An additional line item should be created with M02.
Also the pricing date should be changed.
2. For MOQ changes, I will give the list of orders and the line items
and Qty. The program should reject the existing line item for those
materials. An additional line item should be created with new Qty.
If the material is partially delivered, the the existing qty should be
updated to the extent it is delivered and the remaining qty should be
updated with new material or New MOQ.

You can use BAPI_SALESORDER_CHANGE.
1. Get the SO detail using BAPISDORDER_GETDETAILEDLIST.
2. MODIFY the ORDER_CFGS_* internal tables and update.
        CALL FUNCTION 'BAPISDORDER_GETDETAILEDLIST'
          TABLES
            order_cfgs_value   = gt_char
            order_cfgs_ref       = gt_char_ref
            order_cfgs_inst      = gt_char_ins.
        MODIFY gt_cfgs_*.
        CALL FUNCTION 'BAPI_SALESORDER_CHANGE'
         TABLES
            order_cfgs_value   = gt_char
            order_cfgs_ref       = gt_char_ref
            order_cfgs_inst      = gt_char_ins.

Please HELP !
Regards

Hi PeteA,
Sorry, here it is...
Let me explain the process that has been followed:
1) Initially to start with Service Notification was created with IW51 T-code.
    In that, Sold to party and material # were entered. Then from there directly i go for Create Repair Order from the Action Box.
    Order type for repair order - RAS, and when i save both Service Notification and the Repair gets saved.
    Now, in the repair order, two line items were getting created automatically and the requirement Types for those line items are:
    Line Item I : SE
    Line Item II: SERP
2) After that i take the material in with the help of t-code VRRE.
3) Then, i do the acceptance of the stock ( Technical Check) with t-code QA11.
    Once i do that, i get the Third line item in the Repair Order and the requirement Type for that line item is:
    Line Item III: SERP
Now my query is, Once i do the QA11 transaction i need to get a Service Order automatically but thats not happening.
Also if i create a Service Order manually, and do the repair and do the technically completion of the service order, then i need to get a third line item (IRAL) in the repair order automatically and thats also not happening.

Hi Michal,
I know that it is the old thread but still want to get clarified from you out of curiosity.
Unlike other IDOC, i actiavated change pointers for LOIPRO
1.message and idoc type is linked
2.function module , message type , idoc type is linked
function module used is CLOI_MASTERIDOC_CREATE_LOIPRO
3.BD64, distribution model is created and distributed
4. port and partner profile is in place.
5. IDOC is not getting generated after creating the process order.
do we need to activate the change documents for the message type in BD52,
if yes can you please provide the object types for the same.
or i am missing something else. please guide me in this regards.
Thanks in advance for your time.
