Strange ROWNUM result on query complex using separate results
We have a very complicated query that is a combination of implicit and explicit joins on more than 10 tables in the database. Due to performance issues and timeout if we let him return the entire result set, I'm limiting it to a number using rownum.Initially, we were using a "select * of (select distinct * insert here * order of main by id request) where rownum < = 300 ', but work stopped when a new piece of research has been implemented that makes the whole result set then cut accepting up to 300 results for 5 minutes, which is the maximum of our web server can define for a timeout.
So I tried to change it simply to "select distinct * insert here the main query * and rownum < = 300. This is for a reason any returns only one record. If I add THAT ROWNUM to the list of displayed values it displays 300 lines of exactly the same values with different rownums, who then likely get collapsed down by the distinct in the single record that I see.
Is there a better way to do it? We can't simply not the complete set of results in a subquery to whittle down, but try to whittle down to the main request gives weird results.
A better approach would be to improve the performance of the main query. On the one hand, do come back less (or not) duplicate lines would probably improve the performance considerably, because he's back at least 300 copies of certain lines. Making a DIFFERENT one on a large number of lines can be a problem in itself huge performance.

Here's a way, without all the features:
SELECT a.* FROM source_table a LEFT OUTER JOIN source_table b ON a.origin = b.destination AND a.destination = b.origin AND a.miles = b.miles WHERE b.origin > a.origin -- Not b.origin > b.origin OR b.origin IS NULL ;If you would care to post CREATE TABLE and INSERT statements for your sample data, and then I could test this.

compose the query without using the query designer
New on this BEEP 10.1.3.4.1 product,
questions
1. is there a way to compose a query without using query builder but still has a way to see the result of the query under the PIF?
2. How is - a to compose a query prompt? I know that I can create parm after you create the data set, but at the stage of all data already call you query prompt as where employee id =? E_ID? or just not where clause
Sorry if these questions are too rudimentary, but I did not see that what we have answered according to the user's guide.
Thank you.

'Function SQL Query return' using with Flash graphics
I created a pl/sql function that returns a SQL query in a varchar2 of this form:
Select the null link
-value > < x value
< value y of Series1 > series 1 label
< value Series2 y > 2 series label
< value of y Series3 > series 3 Label
...
...
from tablea a
Join tableb b
On a.col = b.col
order of < x value >
If I call the function of a graphic Flash box series SQL with the Type of Source query "SQL query" value that returns the function like this:
return functionname (to_date ('30-sep-2010, ' mon-dd-yyyy ""))
It parses correctly and the page is saved; However, when I run the page I get no output - error messages or another indication of a problem.
Now, if I call the function in a SQL client, capture the result of the query SQL using the dbms_output and paste that into the box graphic Flash series SQL - change the Source Type of SQL query query - and save the page it works fine when I run it and returns a chart series flash.
Can anyone suggest either;
1. what I might have missed or done wrong?
2. a way to effectively diagnose the problem...
I tried to use the debugger Apex - what is very nice, indeed - but it provides no information on what might be my problem. I tried to write my own my function debug messages using the apex_debug_message package - nothing...
Thank you
EricHi Eric,.
Try to pull the source like this:
begin return functionname(to_date('30-sep-2010', 'dd-mon-yyyy')); end;This works very well for me, and if I take the begin-end and the final semicolon from the return statement I get the same behavior as you.
He doesn't mention in aid of the source (only during the wizard if) this source type must be expressed in this way, but I agree, it would be useful that the tool would validate to this format meets it "Query SQL that returns the function" or give some sort of indication of the sentence. In any case, this should help you will again.
Hope this helps,

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?

Need help to add totals and subtotals query that uses ROW_NUMBER OVER()
Hi all
We have the following query that is used in a report that generates a list of employees working a certain type of movement.
The report also includes a column called RN that is used when the pagination for the report.
What we are trying to do now is to add columns that indicate the total number of hours worked by the employee as well as gran total of hours of work for all employees in the report.
We tried to add the columns last week and have been able to get the totals by using a group by clause. Only problem is that it has changed the order of the column of RN.
The RN column must stay in numerical order, since we need to select and display the records for paging.
Is it possible to get our totals without disturbing our paging RN column?
BTW, thanks Frank for the addition of the UNPIVOT operator at our request. While other solutions worked, UNPIVOT has been the most effective.
SEE below, the application and all the sql to create tables and test data.
Thank you

Hi allWe have the following query that is used in a report that generates a list of employees working a certain type of movement.
The report also includes a column called RN that is used when the pagination for the report.
What we are trying to do now is to add columns that indicate the total number of hours worked by the employee as well as gran total of hours of work for all employees in the report.We tried to add the columns last week and have been able to get the totals by using a group by clause. Only problem is that it has changed the order of the column of RN.
Please your postal code. It is very difficult for me to say what you're doing wrong when I don't know what you're doing.
The RN column must stay in numerical order, since we need to select and display the records for paging.
Is it possible to get our totals without disturbing our paging RN column?
If you mix the aggregate functions and analytical in the query (sub-), the clause GROUP BY is applied and aggregate functions are calculated before the analytical functions are calculated. If you need to calculate the analytical functions first, calculate them in a subquery and make the GROUP BY and aggregate functions in a query Super.
In this case, it may be simpler to use the analytical SUM, rather than the SUM function.
SEE below, the application and all the sql to create tables and test data.
Thank you; It is very useful.
It would be even more useful if you included only the columns you really need, for the party, you don't already know how to do. For example, it seems that you need only to display 2 columns and area areaid to the table areas. ConfigId can be very important for this request, but you already know what to do with configid? It seems that the other columns of this table play no role in this issue and comes confusion.The average time for a first response on this forum is less than 10 minutes. I think people did flee seeing siuch a long message.
... TRUNC ( 24 * (CASE WHEN l.starttime > l.endtime THEN l.endtime + 1 - l.starttime ELSE l.endtime - l.starttime END)) hours,Why do you enter startime after endtime? If they are on separate days, record the days exactly.
... WHERE UPPER (l.leavetype) = 'XYZShift'The expression to the left of the = sign is guaranteed not to contain all small letters, so it will never equal to "XYZShift".
... ORDER BY e.lname||', '||e.fname||' - '||e.initials DESC ,u.startdate DESCA clause using ORDER BY in this subquery is just a waste of resources. (I'm not talking about analytical clauses ORDER BY;) I mean query ORDER BY clauses, like the one above).

Problem strange perf on hierarchical query
Hi gurus,
I have a problem of strange performance on a recursive query. By removing items one by one, I got the query begins to run very slowly when I add a GOLD in the CONNECT BY clause.
The simplified query is the following:
SELECT CONNECT_BY_ROOT( a.c_individu ) ,a.c_individu ,SYS_CONNECT_BY_PATH( to_char(a.c_individu,'FM099999999'), ' ') path ,LEVEL FROM aaa a WHERE CONNECT_BY_ISLEAF=1 AND LEVEL > 1 CONNECT BY a.c_individu < PRIOR a.c_individu AND ( a.prenom_norm= PRIOR a.prenom_norm AND a.d_naissance = PRIOR a.d_naissance AND a.nom_famille_norm = PRIOR a.nom_famille_norm /* OR 1=2 */ )
AAA table contains 10,000 lines for my testing purposes and has an index on C_INDIVIDU.
If I run this query with the 'OR 1 = 2' commented, it runs pretty fast:

If the difference in the execution plan turning access predicates in the filter predicate will slow down performance as Oracle is looking more lines of analysis before filtering every time.
The reason why he chose to do this is because he can not use your predicates connect more to make a hash map of your table based on the predicates. When just using pure equality filters, Oracle managed to the hash table on
PRENOM_NORM, D_NAISSANCE, NOM_FAMILLE_NORM
You need put somehow your new expression on a equal footing, I did the below but it starts from the principle that no line of aaa have nom_famille_norm = ' #', you may need to fiddle.

Just to add that Oracle will use your index because you don't have any starting by conditions so the entire table must be completely digitized. Once the table has been fully scanned it will be in pga is probably still easier to read PGA rather than analysis of the index to find the following lines in the connection by.

IOM Setup integrated with OAM in HA using separate domains
Must configure OAM and IOM in HA and integrated.
Target architecture:
1 is high availability. We have eight servers 2 for each of: level Web, OAM, OAM and OUD.
2 OAM must be integrated with the IOM.3. we use two domains an OAM and another separate domain for IOM.
4 using the version IAM 11.1.2.3
We follow the high availability and guides 11.1.2.3 integration.
On two servers with its domain, we have installed an OAM and IOM on two other servers with her owner field.We used the references:
http://docs.Oracle.com/CD/E52734_01/OIM/IDMIG/OIM.htm#IDMIG32008 (Integration_guide)
- 2.1.2 access Manager and Oracle Identity Manager integration to a single node topology
You MUST set up the components of Oracle Identity Management in distinct areas WebLogic Server (split domain topology), as discussed in Section 1.2.1 "Integration of basic topology", otherwise, try to repair or upgrade a product can be blocked by a dependency of a component shared with another version. When you install the Oracle Identity Management components in a single WebLogic Server domain, there is a risk that you install the component (custom libraries, jars, utilities and plug-ins) in the area is perhaps not compatible with other components, resulting in problems through your domain.
Oracle Identity Manager integration roadmap and Manager to access the section 2.1.3 Says nothing on utilization patterns separate db created by UCR and nothing on the store security DB.
- http://docs.Oracle.com/CD/E27559_01/install.1112/e27794/configtwo.htm#OAMQI76585 (earlier version of IAM)
3.2.9.2 article before you set up the database of store security
Note: Regardless of the number of domains in a logic Oracle Identity and Access Management 11 g Release 2 (11.1.2) deployment (a logical deployment is a collection of products Oracle Identity and Access Management running in one or more domains and use a single database to store product schemas), all areas share the same database to store security and use the same encryption key for domain.
The store security database is created when the first domain is created, and each new domain created is then joined with the database already created security store.We have already installed and configured OAM in its own domain and now wants to configure the IOM in its own domain.
For IOM configured in its own domain and use the same DB as OAM and configured the store DB to help security configureSecurityStore.py with the option to join - Mr. Successfully completed this but OAM had a NAP error message.
My questions:
1. install IOM, MUST create us the separate db schemas when you use the RCU for IOM of OAM? If so, why? Since it is in contrast with the references I listed above. AND the need to ensure that we can OAM integrated with IOM.
2 If can be convinced that they must be separated from the patterns which for each of the OAM and IOM? (I am aware IOM needs: MDS, OPSS, IOM, SOAINFRA, ORASDPM, BIPLATFORM.) But necessarily list OAM)
3 so we can share the same patterns or if need to use a separate diagram, how we create the database of store (AKA strategies store) security? To help create or join mode?
Keeping in mind that we must integrate OAM and IOM.
Not sure if someone has managed to do this configuration.
Thank you
If you're feeling lucky, you can try to fix your updateBIPJMSSecurity.py and then continue, however, if you want to be sure that nothing else could get broken by following the demolition, start from the beginning.

explain query plan uses no unique index with where condition
Hi all
I use in the 10.2.0.5 oracle database Enterprise edition 64-bit on 64-bit windows server 2008.
I'm following this tutorial on my own table
Guide to understanding Oracle QUERY PLAN - 10 minutes
my questions are below
Analyze table LIB_CLASSIFICATIONS compute statistics; explain plan for SELECT class_id FROM lib_classifications WHERE class_no = '538' ; select * from table(dbms_xplan.display);
the result is less than

class_id has a primary key.
now when I remove the condition where the query, the result is lower;
Analyze table LIB_CLASSIFICATIONS compute statistics; explain plan for SELECT class_id FROM lib_classifications ; select * from table(dbms_xplan.display);
the result is less than

------------------------------------------------------------------------------------
now it's using indexes with INDEX FAST FULL SCAN.
I need the index using the WHERE condition as well.
How to do this?
Thank you.
you have indexes on the column class_id not on class_no column how u would expect index to use when there is no index on the column class_no

Tools.syncTime query parameter using PowerCLI
Hey,.
I have a vCenter 5.5 full of virtual machines that I need to test compliance with KB1189 - disabling time synchronization
Using Get-AdvancedSetting I can test and get results for all parameters except 'tools.syncTime '. Is there a way to query this setting?
Thank you
There is indeed no need to perform a Get-view extra, you can do
Get - VM | Select Name,@{N='TimeSync'; E={$_. ExtensionData.Config.Tools.syncTimeWithHost}}

Query not using Full Scan Index
Hello world
I'm on 11.2.0.3.0 AIX 6.1.
There is a query such as:
Select: sys_b_0 | Count (distinct (column_name)) table;
that goes for the analysis full table. The column was values separate only 104 with not NULL values. To save memory buffer gets, I created an index on the table with the column used in the query (i.e. whose distinct values are recovered).
The problem is that even after the creation of indexes and force the flag index that it does not use the full scan of the index. The provided indication is correct in syntax and was the only clue in the query, so there is no question of conflicts with others.
Can anyone suggest me what I might be missing?
Thank you
It seems to me that if print_branch_code is defined as nullable in the table. If this is the case, the optimizer goes for a sweep of index, even if there is no real NULL values

And now the explanation for the result of the query:SYSDATE 28.Feb.13 14:00 ORDER_NR PRIORITYCREATE_DATE STATUS STATUS_DATE DESCRIPTION AGE_1 AGE_2 WAITNG STEP_A STEP_B STEP_C STEP_5 STEP_K STEP_E STEP_F STEP_S STEP_R 1KKA1T205634 12 10.Feb.13 10:00 U 28.Feb.13 12:00 CLEAN HOUSE 18,083 8,833 2,125 0,833 4,125 0,083 0,750 0,208 2,125 0,666 0,042 7,125 1KKA1Z300612 12 08.Feb.13 14:00 F 20.Feb.13 16:00 REPAIR CAR 20,000 16,042 2,125 0,833 4,125 0,083 0,750 0,208 2,125 0,666
The AGE_1 is the difference in days between the "CREATE_DATE" and if EXSIST L'ETAPE 'U' then STEP_DATE or if the STEP 'U' is not found in TABLE_2 then it should show the difference in days between the "CREATE_DATE' and the 'SYSDATE.
The AGE_2 is the difference in days between the STEP "A" STEP_DATE and IF EXSIST L'ETAPE 'R' then STEP_DATE or if the STEP 'R' is not in TABLE_2 then it should show the difference in days between the "CREATE_DATE' and the 'SYSDATE.
The EXPECTATION is the difference in days between CREATE_DATE and STEP 'A' STEP_DATE
The following columns indicate the days, how long the ORDER_NR remains in these TIMES, if an ORDER_NR comes in the same STEP should be calculated together more than once.
If the ORDER_NR jump a step, it should show a zero in the specific field.
I hope that my explanation is good enough, my English skills are far from good.
Thank you for all your help.

Just add the amounts:In fact, you could edit all CASES:

query not using the index for some user
Hello
I have a query that is running in less than a second for sys, system, or schema owner. However, another user (test_user) take 30 seconds to run the same query.
I certainly dba and privileges identical to test_user as schmea_user, but the result is the same.
I checked
Select * from V$ SYS_OPTIMIZER_ENV;
Both are the same for both users.
I have check the plan to explain to both users. I noticed that for sys/system/schema_owner, the query uses an index, but not the test_user.
All have experience the issue where a user uses an index, but not the other?
Thank you for any assistance.Thank you for the display of formatting output, this output is much easier to read.
One of the first things you notice about the execution plans that is for the owner non-schema "SQL_ID, 0wcs85uywn72m, number of children 1" appears in the output of DBMS_XPLAN, while "SQL_ID 0wcs85uywn72m, child number 0" (the same SQL_ID but a different number of child) appears for the schema owner. "" Whereas the SQL_ID is the same, which indicates that the client requires exactly the same SQL statement, so it's a good start.
Then, note that in the predicate for the nonschema owner information section the following appears (sometimes with the order of the two conditions switched in position) as a condition placed on each table that is available in the schema:
filter(("SEAL_FLAG" IS NULL OR "SEAL_FLAG"'Y'))The above suggests the presence of the virtual private database (or a superset of private database virtual) generated the predicates. You should be able to confirm that this is the case by querying V$ VPD_POLICY using the SQL_ID which was displayed in the DBMS_XPLAN output:
SELECT * FROM V$VPD_POLICY WHERE SQL_ID='0wcs85uywn72m';As a test, I made a few minor adjustments to the example on this page:
http://Antognini.ch/2011/09/optimizer_secure_view_merging-and-VPD/
I changed the name of T to T12 and TESTUSER table specified for the schema names. I then created the function S of this page as follows:CREATE OR REPLACE FUNCTION s (schema IN VARCHAR2, tab IN VARCHAR2) RETURN VARCHAR2 AS BEGIN RETURN 'ID < 10'; END; /I then added a couple of lines in the T12 test table:
INSERT INTO T12 VALUES (1,1,NULL); INSERT INTO T12 VALUES (4,1,NULL); INSERT INTO T12 VALUES (10,1,NULL); INSERT INTO T12 VALUES (12,1,NULL); COMMIT;With an active 10053 trace, I executed the following SQL statement:
SELECT id, pad FROM t12 WHERE spy(id, pad) = 1The SQL_ID (in my case, found in the 10053 trace file) was 6hqw5p9d8g8wf, so I checked V$ VPD_POLICY to this SQL_ID:
SELECT * FROM V$VPD_POLICY WHERE SQL_ID='6hqw5p9d8g8wf'; ADDRESS PARADDR SQL_HASH SQL_ID CHILD_NUMBER OBJECT_OWNER OBJECT_NAME POLICY_GROUP POLICY POLICY_FUNCTION_OWNER PREDICATE ---------------- ---------------- ---------- ------------- ------------ ------------ ------------------------------ ------------------------------ ---------------------- ------------------------------ ------------------------------------------------------------------------------------ 000007FFB7701608 000007FFB7743350 1518838670 6hqw5p9d8g8wf 0 TESTUSER T12 SYS_DEFAULT T_SEC TESTUSER ID < 10As noted above, the VPD test function named S added the predicate "ID".< 10"="" to="" the="" sql="">
There are not many clues in the 10053 trace file in my test VPD generated additional predicates. Trace the following was found shortly after the beginning of the file (this is the SQL statement initially presented):
----- Current SQL Statement for this session (sql_id=6hqw5p9d8g8wf) ----- SELECT id, pad FROM t12 WHERE spy(id, pad) = 1I searched then down in the trace for final after changes query file (to be noted that this sentence could be slightly different in different versions of database Oracle). That's what I found:
Final query after transformations: ******* UNPARSED QUERY IS ******* SELECT "T12"."ID" "ID","T12"."PAD" "PAD" FROM "TESTUSER"."T12" "T12" WHERE "TESTUSER"."SPY"("T12"."ID","T12"."PAD")=1 AND "T12"."ID"<10 kkoqbc: optimizing query block SEL$F5BB74E1 (#0)Note that the final query after transformation shows how the final version of the query that has been rewritten by the query optimizer before the SQL statement has been executed and this version of the query includes AND "T12".

"SEAL_FLAG" IS NULLIf V$ VPD_POLICY revealed that there are virtual private database (VPD) generated predicates applied to the SQL statement, take a look at the following article in the Oracle documentation library:
http://docs.Oracle.com/CD/B28359_01/network.111/B28531/VPD.htmThis article lists the different points of view, who can be interviewed to learn more about the VPD rules which are in force in the schema. For example, with my SPV test:
SELECT * FROM ALL_POLICIES; OBJECT_OWNER OBJECT_NAME POLICY_GROUP POLICY_NAME PF_OWNER PACKAGE FUNCTION SEL INS UPD DEL IDX CHK ENA STA POLICY_TYPE LON ------------------------------ ------------------------------ ----------------------------- ------------------------------ ------------------------------ ----------------------------- ------------------------------ --- --- --- --- --- --- --- --- ------------------------ --- TESTUSER T12 SYS_DEFAULT T_SEC TESTUSER S YES YES YES YES NO NO YES NO DYNAMIC NOHe knows performance issues related to the use of VPD, some of which are Oracle Database version-dependent, and some have been fixed in recent versions. Take a look at the following articles if you have access to My Oracle Support:
MetaLink (MOS) Doc ID 728292.1 ' known performance problems when you use transparent encryption data and indexes on the encrypted columns.
MetaLink (MOS) Doc ID 967042.1 "How to investigate Query Performance regressions Caused by VPD (FGAC) predicates?"You might find working through the second of the above that the problem is caused by a bug in database Oracle.
On a side note. Execution plans you have published include the 0 value in the column starts many of the operations in the execution plan. 0 indicates that the operation never actually executed. A 0 is included in the column starts on the line that includes the FULL ACCESS of TABLE of PEOPLE_TRANSACTIONS at least to the OPC. Value 123, a full table of PEOPLE_TRANSACTIONS table scan PROPERTY_CONTAINER_ID was not actually performed.

Hi all
I searched and google it but still not unfortunately translate
I need to make something like this below
I know that I'm not only the use of separate, but what syntax can I use in a way instead. This idea is roughlyselect distinct(t.id, t.place) from table_one
I get the following data below
and I'm counting the results based on the fact that we have no duplicates (ID and location being the same), so published data. The CountyID Place A Berlin A Berlin A Berlin B Berlin B Berlin C London C New york
Any help is appreciated.should be 4, because A Berlin is 1 count B Berlin is another Count C london is another count C New York is another count
