Why index is not used by the subquery?
Hello
ENV: 11 GR 2 on Linux Oracle 5.8 64 bit on file system,
I have the following query:
Select * to processing_instruction pi where pi.last_updated = (select / * + index (idx_pi_client_merchant_status FT2) * / max (pi2.last_updated))
to processing_instruction FT2
where pi2.client_no = pi.client_no
and pi2.merchant_id = pi.merchant_id
and pi2.status = 'C')
I created an index:
CREATE INDEXES TO PROCESSING_INSTRUCTION IDX_PI_CLIENT_MERCHANT_STATUS
(CLIENT_NO, MERCHANT_ID, STATUS)
Oracle still does a full-table scan on the ' processing_instruction FT2 ' table (subquery) even though I also put the indicator INDEX.» The table has rows '55621245 '. There are several lines for a given client_no, the merchant_id and status 'C '. I want to only choose one that has been updated the last (newest one).
I'm sure there may be a better way to do this, but...
Please notify.
Concerning
the order of the keys, and the columns questions
Try (status, last_updated)

Why index is not used on an editable view update?
I need help to understand why Oracle 11.2.0.3 is an index for an editable view. When I refer to the base table, offer$, I access index. When I reference the view, offer, I get a comprehensive analysis of the offer$. There's a trigger on the view instead. Who is factor in there somehow?

Almost certainly.
Even if the view has not used the calls to the function and the trigger was simply "null;" as the body, the presence of the trigger seems to prevent the optimizer to push the subquery view internal and down to the index (and there is no change in 12 c).

Why xmlindex is not used in the slow queries on xml binary table eval?
I run a slow simple query on Oracle 11.2.0.1 database server that does not use a xmlindex. Instead, a full table scan against the table eval binary xml occurs. This is the query:
The predicate is not selective at all - the number of rows returned is the same as the number of rows in table (325 550 in the eval table xml documents). When different values are used, which brings the number of lines down to ~ 33%, the xmlindex still is not used - as is expected in a purely relational XML environment.select -- /*+ NO_XMLINDEX_REWRITE no_parallel(eval)*/ defid from eval, XMLTable(XMLNAMESPACES(DEFAULT 'http://www.cigna.com/acme/domains/eval/2010/03', 'http://www.cigna.com/acme/domains/derived/fact/2010/03' AS "ns7"), '$doc/eval/derivedFacts/ns7:derivedFact' passing eval.object_value as "doc" columns defid varchar2(100) path 'ns7:defId' ) eval_xml where eval_xml.defid in ('59543','55208');
My question is why would'nt the xmlindex be used somehow full scan compared to a sweep of full table that cross the xml for each record in paper table eval?
FFS suspicion would apply to a field of type xmlindex index?
Here is the definition of xmlindex:

Rick BlanchardXMLIndex definition is not correct, for the following reasons:
In the COLUMNS clause, the path expression is compared to the context from the main event of XQuery item (HERE "/ eval").
If you use an initial slash as you did, this indicates that the context item is an element of "derivedFacts" (which is not correct since it is an "eval" element).
Therefore, the path points to no existing node:derivedFact XMLTYPE path ''/derivedFacts/ns7:derivedFact'' virtualThere is a mismatch between the statements of prefix ns7, probably a typing mistake?
''http://www.cigna.com/acme/domains/derived/fact/2010/03'' AS "ns7" ... ''http://www.cigna.com/acme/domains/derived/FACT/2010/03'' AS "ns7"What "eval_xml" is referring to here?
passing eval_xml.derivedFactThe path to "defId" don't go too:
defId VARCHAR2(100) path ''/derivedFacts/ns7:derivedFact/ns7:defId''Try this one, it should help you to:

Why can I not use 'Open the message in a conversation' more?
We are 4 users and both of them have version 24.3.0, and two are on 24.4.0.
We use the option "open message in the conversation" a lot and all of a sudden this option is no longer available. Is there a setting that could have been changed to make it happen?
The only thing that has changed is that I have rearranged our records using "manually sort folders" - this could it be?All messages with a thread of before yesterday are always available with "open message in the conversation", but anything in the afternoon yesterday do not display the option when you right-click and using the swift short ctrl O does nothing.
Any suggestions, what could be wrong are very welcomed.
Thanks guys,.
I think I managed to do the sorting now. I've done the following:
See help at the top and choose "restart with disabled modules.
Are you sure...? Press "restart".
It will now ask you if you want to start in safe mode. Choose this option.
The "manually sort folders work" is now disabled.
Now close Thunderbird and wait a bit.
Now open again, check if you have the Add-ons back - manually sort folders.
Try to click an email again to view the message in a conversation.
And so it works with adding on and open it in the conversation. Very strange but if it works, I'm happy. -

Hi all
I am new to TestStand. Still in the learning process.
What are the parameters? How are Variables differenet? Why we can not use variables to pass data to one sequnece to another? What is the advantage to use parameters instead of Variables?
Thanks in advance,
LaVIEWan
I'm sorry... I discovered that... its not at all possible to pass data to another sequence using variables... it must be through settings... once again I apologize for the display of such a stupid question

I recently used a dvd + rw disk to back up my photos. Now when I put a dvd in my pc, why it will not display on the screen that's all there is, or how to give me access to it?
Depends on what you used for the backup.
If you used the windows backup or another backup software will contain the entire disk will be a backup file, and view/use this file, you use the same software that allows you to save.

How we force a query to use transparently a hint, even if the index is not given in the query as a query rewriting.
For example:
If the user runs a query select deptno, avg (sal) from emp group by deptno;
We want the optimizer to use a hint of result_cache with this request, and it should be transparent to the user.
Query should be rewritten to seamlessly
Select / * + result_cache * / deptno, avg (sal)
WCP
Group of deptno;
How can this feature we make? Please advice.
I checked the possibility of SPM and contours, but it is not clear if this rewrite is possible here.
Thank you and best regards,
Vikas Krishna
Surely dbms_advanced_rewrite is designed for this situation?

After the cancellation of my subscription, why can I not use my old previous Adobe products?
I thought my old apps (CC and CC2014) would always work

When you cancel your subscription, all software related to that subscription will stop working. This includes any software with CC in his name.
The only way to continue to use the CC versions is to re - register.
All versions perpetually under license that was purchased before you subscribed for example, CS4, CS5, CS6 will continue to work as usual.

I just bought a new Mac and migrated my CS6 on. Now, when I open it, I said that I am under a trial of the cloud. Why can I not use my CS6 version that I bought? I don't want to pay for something I already bought.
Here's how to convert the Permanent Trail:
By receiving the expired Trial/test screen
Make sure you are online
Click on software under license
The perpetual owners: connect with the adobe ID and enter the serial number of the product

Why can I not use hidden or display point only to store the value for insertion?
Hi, gurus:
I have a question:
I implemented a form with the region of report in a page, the update works OK, but the add function has a problem:
There is a column, offender_ID, which is a foreign key to another table, it must not be null during insertion. However, even I pass the ID of the author of the offence of master page when user click on the button create and he did watch in the form, it must be a text tabled for insert success, why can I not use hidden or display point only to store this value for insert? (If I use hidden or display single element insert will be successful, apex reports I tried to insert a null value for the offender_ID column.)
Thanks in advance.

(If I use hidden or display single element insert will be successful, apex reports I tried to insert a null value for the offender_ID column.)
I think that both hidden and display elements have attributes that can cause problems because of different ways these function elements as the only non-display and feature no hidden items. The only items have a "Save Session State' yes/no 'control'? This can be a problem.
Would you do that? Do these regular items instead and see if you can get those working. Then, we will try to change the fields back to hidden or display only.

Congratulations. I'm glad you found the solution.

I add an index to the materialized view 'MVISTA' TITULO_PROVINCIA (CSA) and FECHAEXPIRACION (CSA) fields, but it is not used by the query. Why the index is not used? How to define the index serve him?
Thank you very much
One of the reasons for the index is not used because you apply the function nlssort on a single column.
You must use an index of feature based using this function instead.
In addition, I would rewrtite him coalesce to
(VISTA. FECHAEXPIRACION > = SYSDATE or VISTA. FECHAEXPIRACION is null)

SELECT /*+ hint_one */ /*+ hint_two */ column_name FROM table_name;Also I do not believe your INDEX index specification is correct, a single set of brackets should be used and the alias name and index table must be separated by a space or a comma.
So it would be nice...
SELECT /*+ INDEX (table_alias index_name) */ column_name FROM table_name; SELECT /*+ INDEX (table_alias, index_name) */ column_name FROM table_name;But it would not...
SELECT /*+ INDEX (table_alias (index_name)) */ column_name FROM table_name;Also, you should be aware that an INDEX indicator is only considered provided that supports a given join order.
