XMLType and materialized subquery factoring

Hi,
Out of curiosity, I've been wondering what kind of storage is used when a view with an XMLType column gets materialized, for example via the WITH clause.
So I tried :

3           xmltype('<root>Hello!</root>') as doc

7 from t
8 ;
with t as (
ERROR at line 1:

[], [], [], [], [], []Apparently, that's bug #9372157 "WITH clause with XML causes OERI [kkdlsexp:qbcp]" which should have been fixed in 11.2.0.2, but maybe not in XE?
Well, my question is : could someone having access to a full 11.2.0.2 EE check it?
Below is a working example on a "regular" view, describing how to do it :

Subquery Factoring and Materialized Hint

       AND TYPE = 'L'
       AND NVL (lDATE, SYSDATE) = tidate;In the given example the sub query returns just one row because of the aggregate function max. Making this in to a With clause will be of any benefit ? Also i presume/understand that the subquery factoring would be really useful only when we try to make a sub query which returns more rows in a with clause. Is my intrepration right?
Secondly adding the /*+ Materialize */ hint to a With query is mandatory or the optimizer by itself will do it and make a temp table transformation. In my example i am forced to give the hint in the query. Please discuss and help
Thanks in advance.

The solution you adopted has to hit the cache twice and hence do not look very performant. I will advise you to opt for Analytic functions (like the suggestion I provided in another thread). If the solution does not yeild correct results, then provide with a Script that we can replicate (Create table, Sample Insert statement and the expected output).

            select RateB, RateS, Rate, NVL(ldate, sysdate) ldate, dense_rank() over (order by case when NVL(lDATE, SYSDATE) <= ':entereddate' then NVL(lDATE, SYSDATE) else to_date('01/01/1970', 'DD/MM/YYYY' end DESC) rn

Usage of Hints is only for Debugging purposes and is not meant to be used in production code. It is when you have to ascertain the reason for CBO choosing a plan that you do not expect it to take, you use hints to force your plan and find the cost and analyze it. Hence, I do not support the idea of Hints for production code.

The good performing query takes 2 secs, while the bad performing one takes about 8 minutes.
However, if I remove the subquery factoring and include the query as a sub-query it works well.

Has anyone faced this situation ?

Bug in WITH clause (subquery factoring clause) in Oracle 11?

I'm using WITH to perform a set comparison in order to qualify a given query as correct or incorrect regarding an existing solution. However, the query does not give the expected result - an empty set - when comparing the solution to itself in Oracle 11 whereas it does in Oracle 10. A minimal example os posted below as script. There are also some observations about changes to the tables or the query that make Oracle 11 returning correct results but in my opinion these changes must not change the semantics of the queries.
Is this a bug or am I getting something wrong? The Oracle versions are mentioned in the script.

You're all gonna love this one.....
The WITH clause works. But not easily.
Go ahead, build the query, (as noted in a recent thread, I, too, always use views), set the grants and make sure DISCOVERER and EULOWNER have SELECT privs.
1. Log into Disco Admin as EULOWNER. Trust me.
2. Add the view as a folder to the business area.
3. Log into Disco Desktop as EULOWNER. Don't laugh. It gets better.
4. Build the workbook and the worksheet (or just the worksheet if apropos)
5. Set the appropriate "sharing" roles and such
6. Save the workbook to the database.
7. Save the workbook to your computer.
8. Log out of Desktop.
9. Log back into Desktop as whatever, whoever you usually are to work.
10. elect "open existing workbook"
11. Select icon for "open from my computer". See? I told you it would get better!
12. Open the save .dis file from your computer.
13. Save it to the database.
14. Open a web browser and from there, you're on your own.
Fortran in VMS. Much easier and faster. I'm convinced the proliferation of the web is a detriment to the world at large...On the other hand, I'm also waiting for the Dodgers to return to Brooklyn.

How to use subquery factoring ("with" clause) in OWB?

Hi,
Is it possible to use subquery factoring (popularly known as "with" clause) in OWB 10gR2? I have a mapping with a splitter and union-all, which generates a query that has repeated scans of the same table. Subquery Factoring would be very useful here. I think this is a very common situation, so, I hope there's a way to achieve this. (If not in this version, this would be my wishlist item for the next version.)
Appreciate your help.
Regards,
Rahul

Hi Rahul,
I'm afraid you have to put this on your wishlist. You may put the query with the "with"-clause into a view (or table function if you need parameters) if performance is too bad. But that is somehow against the idea (and benefits) of owb.
Another possibility is to use a temporary table and spilt the mappings into two parts: first fill the temp table, then the target table.
Regards,
Carsten.

Oracle equals_path condition NOT working with table and materialized view

The user i am using is xdb with dba role.
1.When i try to use the statement
SELECT PATH FROM xdb.path_VIEW
WHERE
EQUALS_PATH(res, '/home/OE/PurchaseOrders/2002')=1
the result is
/home/OE/PurchaseOrders/2002
2. When i drop the path_view and recreated it like materialized view with statement
create MATERIALIZED view path_view as
select /*+ ORDERED */ t2.path path, t.res res,
xmltype.createxml(xdb.xdb_link_type(NULL, r2.xmldata.dispname, t.name,
h.name, h.flags, h.parent_oid, h.child_oid),
'http://xmlns.oracle.com/xdb/XDBStandard.xsd', 'LINK') link,
t.resid
from ( select xdb.all_path(9999) paths, value(p) res, p.sys_nc_oid$ resid,
p.xmldata.dispname name
from xdb.xdb$resource p
where xdb.under_path(value(p), '/', 9999)=1 ) t,
TABLE( cast (t.paths as xdb.path_array) ) t2,
xdb.xdb$h_link h, xdb.xdb$resource r2
where t2.parent_oid = h.parent_oid and t2.childname = h.name and
t2.parent_oid = r2.sys_nc_oid$
then the equals_path condition STOP working !!!
3. The same experiment, but i recreate it like table
create table path_view as .... using the rest of the statement ...
Can someone help me to understand why equals_path is NOT working on table and materialized view !

Thanks Jonah. I was under the impression that I already had it but seems like it has to be a direct priv - thru a role doesn't work.
I granted the reqd privs and then it worked fine. Thx for your help!

Recursive WITH (Recursive Subquery Factoring) Never Returns

11.2.0.2 database on Windows, SQL Developer Version 3.2.20.09, build MAIN-09.87 (Database and SQL Developer are on the same machine. I have also tried connecting to a Linux 11.2 database and have the same results.)
I've been doing some simple testing with recursive WITH (Recursive Subquery Factoring) and when I run this following statement in SQL*Plus it returns instantly. However when running in SQL Developer it never returns, I've let it run for quite a long time (172 seconds) and gotten nothing, I finally kill the statement. Once I ran it and even killing the job didn't come back. I can get an explain plan but if I try to run it, run as script or autotrace it never returns. I have only one plan in the plan_table for this test, and it's only 4 lines long. No errors, no messages.
WITH get_plan (query_plan, id, planlevel) as
select ' '||operation||' '||options||' '||object_name query_plan, id, 1 planlevel
from plan_table
where id = 0
union all
select lpad(' ',2*planlevel)||p.operation||' '||p.options||' '||p.object_name query_plan, p.id, planlevel+1
from get_plan g, plan_table p
where g.id = p.parent_id
SELECT QUERY_PLAN FROM GET_PLAN ORDER BY PLANLEVEL;

Hi Jeff, using either give the same results. The query is "running", as is the little graphic with the bouncing gray bar is moving back and forth saying either "Query Results" or "Scriptrunner Task" as appropriate.
OK this is odd. I run a count(*) on plan_table in SQL*Plus and get 4, in SQL Developer I get 487. Hun? That makes no sense I'm connect as the same user in each. Where are all these other entries coming from and why can't I see them in SQL Plus? Does SQL Developer have it's own PLAN_TABLE?
**EDIT --- Yes that seems to be the case. The PLAN_ID I see in SQL Plus doesn't even exist in the SQL Deveropler version of the table. OK that's good to know. I assume the plan_table for SQL Developer is local to it somehow? It's not in the database as best I can see.

bigtable used many times in select to avoid Subquery factoring used (with select) but it increased cost as per explain plan in sqldevleoper please suggest me to increase performance
Lots of thanks,
Kalinga

now the above query use as
with subfact as
( select
select
columns
from
bigtable
where
<condition with recdate and modified date
select
a.colums,
b.columns
from
( select
Colums
from
F ,
subfact
where condition
) a,
( select
Colums
from
tables,
subfact
where condition
) b
it is cost increased in nested loop in explain plan why? is thre any other detail required.

WITH Subquery Factoring OR "Scalar SubqueriesRun Another Query per row

Hi Experts
Please suggest
which one query is better
Involved table p is of size 2GB and c1/c2 of size 800M.
And we have to run a report on p which will do FTS (no where clause on p)
So FTS on 2 GB table and then running Another Query per row .. so results job very slow
1) Select p.id,
         (select sum(q1) from c1 where c1.id = p.id) c1_sum1,
         (select sum(q2) from c2 where c2.id = p.id) c2_sum2
   from p
2)
WITH Subquery Factoring
with c1_vw as
(select id, sum(q1) c1_sum1
    from c1
         group by id),
   c2_vw as
   (select id, sum(q2) c2_sum2
       from c2
      group by id),
   c1_c2 as
   (select c1.id, c1.c1_sum1, c2.c2_sum2
       from c1_vw c1, c2_vw c2
      where c1.id = c2.id )
   select p.id, c1_sum1, c2_sum2
      from p, c1_c2
     where p.id = c1_c2.id
   / 10.2..0.4

Its hard to say which query will run best without running both, getting execution plans, and run-time statistics. At a pure guess I would think all things being equal they would have similar performance but do not really know.

With clause of select (subquery factoring)

I've got a script that looks like this:
with X as (select * from atable)
select x1.*, x2.*
from X x1,
X x2
This works perfectly well in SQL*Plus, in PL/SQL, etc. Yet when I try to add it as "New Folder from Database" to an existing Business area in Discoverer, I get the infamous "ORA-03001 Unimplemented Feature".
What am I doing wrong?
Oracle 9i, Disco 9.0.4

Hi,
You will have to define a database view containing your query and load the view into your database. I don't think you can use subquery factoring in a custom folder.

What are the precautions to be taken while archiving the POs' and Material

Hi All,
I want to archive the Purchase orders and Material documents. Is there any standard rule to follow this procedure. What are the further consequences for the consecutive documents. And how do you check the open POs' of all.
I have archived PRs' and Invoices, but these are not interlinked.
Could you please help me in this, so that I will be very much thankful to you.

PO number and material issued against this PO for subcontracting

How to know the link in between the PO number and material issued against this PO for subcontracting.
I have checked that PO history is not getting updated.
Thanks,

Hi,
We have 2 different scenarios where you can post a goods issue to Subcontract Venodrs.
Scenarios 1: You can post the goods issue against a subcontrac vendor with out referencing the Subcon PO from ME2O, at this stage we will be knowing what is the stock at subcontract vendor but we will not be knowing the issues against which and how much Quantities are posted.
So when we are post goods receipt, then we will come to know the consuption quantities.
Scenario: 2, If we use the delivery concept then we can track the goods issues against the subcon POs.
If you really keen to track the material issued to Subcon vendor against a PO so better use with delivery.

Satya.

How to find the Open sale orders till date for given plant and material ?

Hi experts,
                 I have a requirement to calculate the open sale orders for a given plant and material. I have tried in VA05 wherein i can get only for the material and sales area combination. From the document nos obtained from VA05 i can then find the plant. But my question is how do i get the output of VA05 into my progra. (can i use submit for a module pool report ).
Also if ther is some other standard table or Function module to find the open sale orders till a given date ,it will be even more helpful....in which case i can drop the VA05 route.
Kindly help
Thanks in advance
Ashwin

Hi Ashwin,
    You can use SAP Tables VBAK and VBUP to get to know if the document is complete or not.
   VBUK-GBSTK is the field that will give you the status of the Sales Order .
VBUK is used at header level , whereas VBUP is used for Item level.
So in your case what I would do is :
Get the Sales Orders that satisy the plant and material criteria from VBAP table , take this Sales Document numbers and go to VBUK or VBUP table to get the Sales Order Status.
   If I need to find the open quantity as well I will link to VBFA table based on the document number.
Reward if helpful.
Thanks,
Imran
