Why the content of the Explain Plan not show out?
I am using Oracle 11g.
I already ran the utlxplan.sql sctipt and I also set serveroutput on.

When you say:
My release 10.2 database display the Explain Plan automatically.
How to make 11.1.0.6 Oracle database to display the Explain Plan automatically.What do you mean? Specifically, what commands are you executing in the 10.2 database, that displays the execution plan "automatically"?
Are you saying that if you execute the same command in 11.1.0.6, you don't get a similar result? What happens? Do you get an error?
For both the 10.2 case and the 11.1.0.6 case, post the full output of the commands you're executing, and the result you are seeing.
Then, maybe someone can help you.
When you post the output, please encapsulate it in a pair "code" tags, which is the word "code" without the quotes, surrounded by a pair of curly braces {}.
When you do this correctly, the output looks like:
This is output from my execution plan run.and is much easier to read.

Why the iPhone dose not show the witting in case if the other person have a call and I'm on witting? really I'm dissappointed with this point Why we do not have this service?
That is not a feature of the iPhone (or of any phone I've ever had so apparently it's far from universal). Apple has not said why they have no such feature.
You can request such a feature here:

Why the explain plan incorrent?
I have a sql in oracle10.2.03:
select *
from (select a.*
from t_user a, t_message b
where b.user_id = a.row_id and a.user_type = 1
order by b.happen_time desc)
where rownum <= 5
there are indexes on column a.user_type,b.user_id,b.happen_time, and has been analyzed. a.user_type=1 only have 1/1000 records
the explain plan is below:
cost Cardinary Bytes
SELECT STATEMENT, GOAL = ALL_ROWS 30 5 3790
COUNT STOPKEY
VIEW BMTEST 30 6 4548
NESTED LOOPS 30 6 1158
TABLE ACCESS BY INDEX ROWID BMTEST T_MESSAGE 13 1524118 24385888
INDEX FULL SCAN DESCENDING BMTEST IDX_MESSAGE_2 1 168
TABLE ACCESS BY INDEX ROWID BMTEST T_USER 1 1 177
INDEX UNIQUE SCAN BMTEST PK_USER 1 1
Oracle use the index full scan descending on the happen_time. the cost only has 30.
After I add hint on the sql on the user_id of t_message
select *
from (select /*+index (b idx_message_1)*/ a.*
from t_user a, t_message b
where b.user_id = a.row_id and a.user_type = 1
order by b.happen_time desc)
where rownum <= 5
the explain plan change to:
cost Cardinary Bytes
SELECT STATEMENT, GOAL = ALL_ROWS 5020 5 3790
COUNT STOPKEY
VIEW BMTEST 5020 54707 41467906
SORT ORDER BY STOPKEY 5020 54707 10558451
TABLE ACCESS BY INDEX ROWID BMTEST T_MESSAGE 26 515 8240
NESTED LOOPS 2707 54707 10558451
TABLE ACCESS BY INDEX ROWID BMTEST T_USER 1 106 18762
INDEX RANGE SCAN BMTEST IDX_USER_2 1 106
INDEX RANGE SCAN BMTEST IDX_MESSAGE_1 1 515
INDEX UNIQUE SCAN BMTEST PK_USER 1 1
The cost is 5020, but the execute usage time only is 100ms, and the first SQL does not add hint usage 20s.
Why the lower cost waste more time, if the cost caculate is incorrect?

But i am afraid i use a misunderstand title for this post,my doubt is why oracle get a large cost with the sql execute few time but get a small cost with the sql execute long time.The cost of a query isn't a particularly good proxy for runtime. It is perfectly reasonable for a query with a cost of 1000 to run more quickly than a query with a cost of 100. The cost of queries is only directly comparable between different plans in the same 10053 trace file.

All the indexed columns are both analyzed by the command or by DBMS_STATS package and the cpu costing is enabled.But what order are the commands being run? And why is the ANALYZE command being used to gather optimizer stats.
In the first plan:
INDEX FULL SCAN DESCENDING BMTEST IDX_MESSAGE_2 1 168
Why this index full scan cost only 1? how did oracle get this number? Is there formula to caculate the cost of index full scan? I have read the article named "Cost Based Oracle Fundamentals" and there is no introduce how to caculate it.
I think this abnormality cost makes the cost of next step "NESTED LOOPS" very smal and finally lead this abnormality result.1) Which article are you talking about? Are you talking about Jonathan Lewis's book "Cost Based Oracle Fundamentals"? Or are you referring to a different article somewhere?
2) Can you post the query plans formatted via DBMS_XPLAN.DISPLAY (including the predicate information and enclose the output in the \[pre\] and \[pre\] tags to preserve white space?

Why the Image is not showing on Report at runtime?
Post Author: azharrahi
CA Forum: .NET
I am working on a web site which was developed in ASP.Net 1.1. This web site also contains Crystal Reports version 9.
Now I have loaded the web site in Visual Studio.net 2005 and hence in ASP.Net 2.0. Still the Crystal reports version is 9.
Everything is ok and Crystal reports are showing data properly.
But one thing is very strange and annoyable.i.e. When I insert image on Crystal Reports through right click-> Insert->Picture, the image is shown in the design time preview of report, but when I load the Crystal Report on .Net control CrystalReportViewer and run the application, the Image is not displayed. The problem becomes more strange when I Export the Crystal Report to PDF file and MS Excel. Strangely the Image is also exported there and is displayed. Whats the problem? Why Image is not displayed on the CrystalreportViewer of the form on run time and why on exporting to PDF file and MS Excel, it is displayed? Can any body tell me whats the problem behind of not displaying image on runtime?
At least it means that Image is embeded and loaded on runtime. Only now viewing. Only a blank Picture box displayed.Post Author: Argan

A couple things can cause this.
Right click on the red x to find out the name of the png file. Search the web server for that png and make sure that the asp worker has access to it.
The other is a image handler issue. Search the kbase for Red X NET 2005 and you will find a kbase or two that addresses this. -
the program can run, however, the image just dose not show on the container, I've mad ....

Why the subvi can not show,when i use call by reference node.
I used a call by reference node in function pallete,i follow the labview manuals and examples(dynamic load example), but i can not see the subvi show when the program running.

交流稳态频谱.vi 19 KBHi Sunny,
Open your subVI,
1. go to File->Vi Properties (or Ctrl+I)
2. choose Window Appearance category
3. choose Customize
4. check "Show Front Panel When Called" (and "Close Afterwards ..")
5. save the VI, close it and try again.
Let us know if it's OK ... -
Explain plan not available in dba studio
Hi, guys,
Why the explain plan not available in my dba studio with a message like this "explain plan not available for this sql statement. ora-02195: attempt to create permanent object in a temporary tablespace"
Another question: I can use "set autotrace on" to trace sql statement in sql*plus window. But the final execution plan come up without those thing like cost, cardinality but only the steps
Thanks for your help
jimWas this a trace started on an already running task? Was the trace stopped before the task completed? Did the trace file reach its set size limit before the task compled?
In all three cases above you would have cursors that were not closed and stats information not written to the trace file resulting in incomplete data for some SQL.

DECODE is changing the explain plan
I have a statement with a decode function in the where clause like this:
AND decode(:cropcode,-1,'-1',sdu.u_crop_group) = decode(:cropcode,-1,'-1',:cropcode)When I a pass -1 as parameter for cropgroup the filter would result in "AND '-1' = '-1' and the statement is executed in less than 2 seconds. When I leave out this where clause it takes almost 18 seconds. The result is the same so I don't understand why the explain plan is so much different and why not using index scans in the statement without decode.
Below the explain plans and tkprofs for 1 (without decode) and 2 (with decode).

Why can the explain plan be different from 2 exact set of structures
hi,
i have from a view some base tables let's say A , B, C & D
this query is running very slow . so from the same database , i created tables A1 , B1, C1,& D1 from the above tables.
i created some new indexes on A1 to D1 tables and the results returned to me is fast.
i did an exlain plan
so i drop the indexes on the original A to D table and created the new indexes as per A1 to D1 and analyzed them. and i also did an explain plan
but the query is still running slow and also the explain plan is different to the one from A1 to D1 (the one that running fast)
pls help me to understand how/why can this happen ?
tks & rdgshi,
precisely i could have been providing insufficient information but i am too inexperienced to be able to give you the required information and i am also not very sure where i could get the info so that you all can advise me further.
but this is from the user_tables , the only difference i see is that

How to change the explain plan for currently running query?
Hi All,
I am using Oracle enterprise 9i edition. I have a query which frames dynamically and running in the database. I noticed a table with 31147758 rows
in the query which has no indexes and taking more time to process. I tried to create an INdex on that table. I know the query is already running with a FULL table scan. Is it possible to change the explain plan for the current running query to consider the INDEX?

AND a.glbl_uniq_id = p.glbl_uniq_id
AND p.daterank > 1
AND a.pscr_pack_id = d.att_dit_id
[/code]
The table lrx_tmp_pat_daterank is having that 31147758 rows. So I am wondering how to make the query to use the newly created index on the table?Why do you think using Indexes will improve the performance of the query? How many rows this query is returning? Optimizer might chose a Full table scan when it finds out that Index plan might not be useful. Why are you using /*+ USE_HASH (c,e,b,a) */ hint? This Hint will force oracle to use Full table scan instead of using the index. Try removing it and see if the plan changes.
