Where is the result of the following query caching?
I run the following query statement:select * from hr.employeesBy definition is not "cache". The blocks of data that are read to retrieve the results of the query are retrieved in the cache (DB_CACHE_SIZE or DB_BLOCK_BUFFERS component BMG) buffers so that they are accessible on several occasions by the same users or other users. However, because the buffer cache is limited in size, buffers are released when new blocks to be read. Buffers for a full table scan (as it would be for such a request) are released very probably earlier.

I have following table structures and data...
And I wrote the request in order to obtain records that are superior to BBB-
But could you please me to write in a simpler way.

Query - Gohan values in the following columns of aging
Oracle 11.2.0.3...
I have this query... working on it in SQL * Navigator.
We pay all suppliers with Net 20, 25 Net and Net 30 terms due date + 15 days. I'm developing an application that will tell me who is due now, which must be returned within next 7, then 10, then 14 and coming 21 days.
The following query returns not due, owed, due + 7, etc... but just what is due is also displayed in the + 7, + 10, etc - because if it's due, it will be always due in a week!
How can I remove these values if they are already due?
(or, if they are due in 7 days, how can I delete + 10, + 14, etc?)

Published by: camforbes on January 8, 2013 13:24Hello
It's not very clear what you want, but I think something more or less like that will do what you want:

JOIN nps ON ... WHERE nps.amount_remaining != 0 AND inv.terms IN ('Net 20', 'Net 25', 'Net 30') ) SELECT pv.vendor_name , nps.invoice_number , nps.invoice_date , nps.due_date , inv.terms , days_entered , days overdue , CASE WHEN grp = 'Not Due' THEN amount_remianing END AS not_due , CASE WHEN grp = 'Due' THEN amount_remianing END AS due , CASE WHEN grp = '+7 Days' THEN amount_remianing END AS plus_7_days , CASE WHEN grp = '+14 Days' THEN amount_remianing END AS plus_14_days , CASE WHEN grp = '+21 Days' THEN amount_remianing END AS plus_21_days FROM got_grp ;Whenever you have a question, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
If the results are dependent on when the query is run, give an exact time of execution, or better yet, give a couple of different run times and desired outcomes, the same sample for each data.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

Performance problem on the SQL query that does not use the primary key index
Hello!
I have some performance issues on a single SQL query (Oracle 10 g).
I could solve the problem by using the INDEX indicator, but I would like to know WHY this is happening.
* Tables *.
create table jobs)
ID number (5) not null,
name varchar2 (100),
primary key constraint Job_PK (id)
)
/
-Record count: 298
create table Comp)
integer ID not null,
name varchar2 (100),
primary key constraint Comp_PK (id)
)
/
-Record count: 193
-Relation m: n
create table JobComp)
integer ID not null,
id_job integer not null,
id_comp integer not null,
primary key constraint JobComp_PK (id),
unique key constraint JobComp_UK (id_job, id_comp),
Constraint JobComp_FK_Job foreign key (id_job) refers to Job (id),
Constraint JobComp_FK_Comp foreign key (id_comp) makes reference Comp (id)
)
/
create index JobComp_IX_Comp on JobComp (Cod_Comp)
/
create index JobComp_IX_Job on JobComp (Cod_Job)
/
-Record count: 6431
* Ask *.
When I run this query, the execution plan shows the index using (JobComp_PK and JobComp_IX_Comp).
No problem.
Select JobComp.*
of JobComp
Join jobs
on Job.id = JobComp.id_job
where JobComp.id_comp = 134
/
-runs in 0.20 sec
But when I add the field 'name' of the work table the plan uses full access table to the table of work
Select JobComp.*, Job.name
of JobComp
Join jobs
on Job.id = JobComp.id_job
where JobComp.id_comp = 134
/
-runs in the 2.70 dry
With the help of the index
Select / * + INDEX (Job Job_PK) * /.
JobComp.*, Job.name
of JobComp
Join jobs
on Job.id = JobComp.id_job
where JobComp.id_comp = 134
/
-runs in 0.20 sec
* Doubt *.
This behavior is correct?
PS. : I tried to recalculate the statistics, but nothing changes:
analyze the job calculation table statistics.
/
change the statistical calculation of index Job_PK reconstruction;
/
Start
dbms_utility.analyze_schema (sys_context ('userenv', 'current_schema'), 'CALCULATE');
end;

Hello.
I'm sorry for the plan unformatted.
The execution time of the querys "without field name' and 'with the field name with suspicion" are equal.
He has no problem caching, because I get the plans of the sequence different from the querys and repeated the performance. The result is always the same.I don't think that there is no problem with oracle crossing LOOP IMBRIQUEE to the HASH JOIN when you include the field name and this should be the expected behavior. But it seems that your WORKING table has a degree of parallelism set against what is causing the query to run in parallel (as JOB table is now available with full table scan, instead of indexed access earlier). It could be that the parallel execution is contributor to extra Runtime.
(a) do you know why the degree of parallelism on the WORK table has been defined? Do you need it?You can see if the following query provides a better response time?
select /*+ NOPARALLEL(JOB) */ JobComp.*, Job.Name from JobComp join Job on Job.id = JobComp.id_job where JobComp.id_comp = 134 -

Error giving a subquery, but with the outer query, it gives no error.
Hello
The following query gives error "ORA-00979: not a GROUP BY expression" (I know to use the filter condition in the WHERE clause, but for reasons explaining the problem, I use the HAVING clause)

finished in the msg below:-ora-56902: wait for the aggregate within the operation of pivot function
can you please help me to fix it.
Concerning
YramHi, Yram,
Whenever you have a problem, after a few sample data and outcomes from these data.
Sorry, I can't make a good guess at what you want, and I'm not an Oracle 11 database now to test. I think you want something like this:WITH AGBUCK AS ( SELECT AGING_BUCKET_ID , DAYS_START , DAYS_TO || TYPE AS label FROM AR_AGING_BUCKET_LINES WHERE AGING_BUCKET_ID = 3 ) SELECT * FROM agbuck PIVOT ( MIN (days_start) FOR label IN ( '0 CURRENT' AS current_0 , '30 PAST' AS past_30 , '60 PAST' AS past_60 , '90 PAST' AS past_90 , '9999999 PAST' AS past_9999999 ) ) ;The first thing inside the parentheses after the PIVOT keyword must be an aggregate function. If there is a one-to-one correspondence between the lines in the "input" table and cells in the output, so no matter if you use the MIN or MAX (or, in the case of numbers, AVG or SUM).

Better way to write the simple query?

It is an example, I imagined, since I can't post our actual data. The following query works, but is their path easier.
Reason, I take the ID's for the second join because I know that the ID max = max.CREATE TABLE TEST_TABLE ( LOAN_NUMBER VARCHAR2(15 Byte), UN_ID NUMBER, CHANGE_DATE DATE, PROP_TYPE VARCHAR2(25 Byte), OCCSTAT VARCHAR2(25 Byte) ); COMMIT; INSERT INTO TEST_TABLE VALUES (123456, 1,'01-JAN-09','Tent','Occupied'); INSERT INTO TEST_TABLE VALUES (123456, 2,'01-FEB-09','Shack','Occupied'); INSERT INTO TEST_TABLE VALUES (123456, 3,'01-JUN-08','Single Family','Occupied'); INSERT INTO TEST_TABLE VALUES (123456, 4,'01-OCT-08','Single Family Plus','Occupied'); INSERT INTO TEST_TABLE VALUES (123456, 5,'01-DEC-08','Mansion','Occupied'); INSERT INTO TEST_TABLE VALUES (123456, 6,'05-JAN-09','Mansion','Unoccupied'); COMMIT;
easier way without the second join?select i2.UN_ID, i2.CHANGE_DATE, i2.PROP_TYPE, i2.OCCSTAT from ( select distinct(LOAN_NUMBER) AS "LOAN_ID", max(UN_ID) AS "ID_MAX" from( select LOAN_NUMBER, UN_ID from TEST_TABLE where OCCSTAT = 'Occupied' group by LOAN_NUMBER, UN_ID ) group by LOAN_NUMBER )i left join TEST_TABLE i2 on i.ID_MAX = i2.UN_ID
Thanks in advance.
RTry this query, it should be equivalent to your:
select UN_ID, CHANGE_DATE, PROP_TYPE, OCCSTAT from ( select LOAN_NUMBER, UN_ID, CHANGE_DATE, PROP_TYPE, OCCSTAT, rank() over(partition by LOAN_NUMBER order by un_id desc) rn from test_table where OCCSTAT = 'Occupied' ) where rn=1Max

Hello.
I'm just trying to understand a few things about the BI server cache.
1. is there a time-out for the server cache BI which means how long it keeps the cache and when it should be deleted. Y at - it all the parameters that can be set to determine when the server cacahe BI expires.
2. when clears it BI server than the cacahe y at - it an order in which it gives off the sense cacahe if she has 10 inputs and reached a limit how he chooses only 10 entries to remove. How to determine which is deleted.
All documents pointing to the same thing with useful as well.
Thanks and greetingsHello
In the case where if the time persistent cache is defined at the level of the physical table, then the cache associated with this table will be deleted after the time interval specified. Another stratergy to remove the Cache is using the events polling mechanism. There are also other ways to purge the cache. In addition, according to the value set for MAX_CACHE_ENTRIES in the NQSConfig file, the cache entries are replaced based on the algorithm least recently used (LRU).
Below are the links for more details:

How to enable the Java Script function in APEX 4.2.6 running on the result of an Xquery query.
How to take a SQL query result in the source section of an APEX "agenda of the page" field and allow this request to be formatted using XML in an HTML format for a Java Script file to perform a function on the result?
Currently I have the following text:
To query the DB table and format the result as HTML:
SELECT XMLELEMENT ("UL id ="ticker01"', XMLAGG (XMLFOREST (Scroll_Mess AS LI))") "item UL' OF Web_Ticker where Mess_Id < 10 order by Mess_Id;
That displays the following:
< UL id = "ticker01" > < LI > HELLO < /LI > < LI > HELLO < /LI > < /UL id = "ticker01" >
I need the output of this to be visible to a JScript function that is currently called the "head of page", but there doesn't seem to be its scope? The function works correctly if there is a list in the page field items 'Text element Pre' but does not work correctly when used in conjunction with the query to generate a table form.
If everyone is happy to help I would be grateful .
James.
Solved!
In order for the request to be part of the DOM of the page of the APEX, the Java Script allows to perform its function on the result marked "HTML" to query, you must set page of the apex on which the query resides and then add the inner text of this page to a second variable for which the function of web ticker can run on as follows:
$(function() {})
var x = $("#P9_TICKER_DATA");
var y = x [0] .innerText;
x.Append (y);
$("UL#ticker01").liScroll ();
});
From there, on the Java script is able to properly see the result of the query in HTML format.

Hello
ORA-01489 is one of these error messages that really means what he says. The error message you posted pretty much sums up the situation.
What version of Oracle are you using? (You must still include this whenever you have a question. See the FAQ forum: Re: 2. How can I ask a question on the forums? )
From 12.1 of the Oracle, there is an option to allow VARCHAR2s in SQL to be as big as 32767octets. (The default is 4000).
Otherwise, if you can't change the code, either do not run. or ensure that the concerned channels are quite short so the error does not occur.
