Help returns the array of query results
Hi all... Pretty new to this so please forgive my ignorance. Running Oracle 11 g, trying to return results as in the example I give below. I don't know how the Sport field will have unique values, and I don't know how many unique values the year field is seen in the data. Does anyone have recommendations/suggestions?The structure of the table is:
Year of sport
Baseball 10-11
Football 10-11
Football 11-12
Football 11-12
Football 11-12
Baseball 11-12
The result should be sports in each year and should be grouped by year but shown as columns so:
(GROUP OF the year)
1, baseball 1, Football
2, 1, Football Soccer 1, Baseball
I hope that makes sense. Thanks for any help!

Does anyone have recommendations/suggestions?
Maybe something like:
SQL> with t as (
select 'Baseball' sport, '10-11' year from dual union all
select 'Football', '10-11' from dual union all
select 'Football', '11-12' from dual union all
select 'Football', '11-12' from dual union all
select 'Soccer', '11-12' from dual union all
select 'Baseball', '11-12' from dual
)
--
--
select year, listagg(cnt || ', ' || sport, ' ') within group (order by cnt desc) sports from (
select count(*) cnt, sport, year from t
group by sport, year)
group by year
/
YEAR SPORTS
------- ----------------------------------------
10-11 1, Baseball 1, Football
11-12 2, Football 1, Baseball 1, Soccer
2 rows selected.

Help on the game of query results
Hi gurus,
Have this survey for my requirement of dataset sql.
Sample, it's that I have to pick up the nonfunctional currency transactions.
Lets say for a given month, data that are present are for CurrencyA and CurrencyB for a particular account.
Account1 has a transaction does not work CurrencyA and CurrenyB then Account2 has only transaction to CurrencyB.
My current query result is that the 3 first lines, what I need is the 4th should also appear and be included.
CurrencyA - amount - account1
CurrencyB - amount - account1
CurrencyB - amount - Account2
CurrencyA - < '0' / or null >-Account2
I think that my request is based on the currency < x > I have, so it should be for each account, he has all the lines for each currency.
If please notify and let me know your thoughts.
Kind regards
Hello
It looks like you want an outer join partitioned.
I hope that answers your question.
If not, 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.
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).See the FAQ forum: https://forums.oracle.com/message/9362002

Input processor may not return the array
Hi all
I've set up an EntryProcessor to return the results of the calculated amounts, however, under the exception is thrown when retrieving the result. Any idea? I tried to change to return BigDecimal instead of BigDecimal [], it works. Why?
Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; incompatible with [Ljava.math.BigDecimal;
BigDecimal results = (BigDecimal []) CacheHelper.getCounterPartyCache () .invoke (new FttCntptId("052753"), new CreateOrderProcessor());

Hi Henry,.
It can return the paintings, but he cannot return correctly typed arrays.
On the client side, this table has been deserialized as an Object [] and not as a BigDecimal [] and, therefore, it cannot be cast to BigDecimal [].
So just change the declaration of the Object [] results variable and do the distribution on the elements instead.

VcHostVirtualSwitch 'portgroup' object property returns the array of channels, no objects
Something seems a little wrong here; on a vSphere 5.5 installation, you ask a traditional vSwitch (IE not dvSwitch) for exchanges that I do not receive the table of object of type [VcHostPortGroup], but rather an array of flat strings that cannot be extended.
This seems to break the shares provided for registration of trade as well as my own code, so I suspect that some changes in the API 5.5 can have passed unnoticed since so few people more uses vSwitches.
Could someone check the following code and see what happens:
var hosts=Server.findAllForType("VC:HostSystem"); var host=hosts[0]; var switches=host.configManager.networkSystem.networkInfo.vswitch; for (var i=0; i<switches.length; i++) { vswitch=switches[i]; System.log(vswitch); var pglist=vswitch.portgroup; for (var n=0;n<pglist.length;n++) { var pg=pglist[n]; System.log (pg); System.log("Found portgroup "+ pg.spec.name +" with vlan ID "+pg.spec.vlanId); // This breaks } }
Okay, so I figured this out on my own.
There is a bug in the documentation in the API of vCO HostVirtualSwitch object does not point to a group of ports, but rather returns an array of strings "flattened" with the keys (not unique, useless) to the port associated with the vSwitch groups. It is correctly stated in the vSphere API reference but incorrect in the version of vCO, which may indicate that the code real vCO is incompatible as well.
To recover a real populated HostPortGroup object you must descend through the successful HostNetworkInfo object; the portgroup here property is an array of the appropriate type.

Calling a database procedure which returns the array as output parameters
Hello
I wanted to call a procedure that returns "T_Disponibilidad_Diaria".
Type T_Disponibilidad_Diaria is Table of the R_Disponibilidad_Diaria
INDEX OF DIRECTORY;
Type R_Disponibilidad_Diaria is {Record
}
Please suggest me the best way to convert this type of array complex java object
Thanks in advance
Concerning
VidyaBut what you can do...
Try to create a new stored procedure, which returns the type of the database object.
In this procedure, you can call the original procedure.
Take what it returns and make the type object. That's what you need to retrieve your procedure ;-) (.. .huh?) -
limit the number of query results for content Presenter CMIS
Hi dear,
I have a problem. I added content present on my page in Jdev ide, not at run time. And I need a query including the limitation of the number of results.
My query is: ${' SELECT * from ora: t:IDC:GlobalProfile WHERE the ora: p:xRegionDefinition =-"CSGMNEWS_REGDEF\" ORDER BY ora: p:dInDate DESC'}
I just want to add a number parameter.
Can you help me please? How can I limit the number of results?
Kind regards
Yacouba
Published by: erdo on 21.Mar.2013 18:37Hello.
Content Presenter has a setting (maxResults) to set the maximum returned results:
Sample:
xmlns = "http://xmlns.oracle.com/adf/controller/binding" Refresh 'ifNeeded' = >
When you add your CP to a page at design time, you can access the pageDefinition and provide more values for attributes of CP.
I hope this help you.

the case-insensitive query results
I got a help from 11g with the suite of version information
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - Production
PL/SQL Release 11.1.0.7.0 - Production
CORE Production 11.1.0.7.0
AMT for 32-bit Windows: Version 11.1.0.7.0 - Production
NLSRTL Version 11.1.0.7.0 - Production
The result of the query are case-sensitive
Ex: Select * from Table_1 where column like '% new % ';
result: News
But do not go back NEWS News or newsThe result of the query are case-sensitive
But you want the results to be case-insensitive?
Well, then you can use:Select * from Table_1 where lower(column) like '%news%';
And use a function based index.

How to speed up the time to query result
When executing the following query, the result comes after 22 seconds.
How I minimize this time? Please suggest.
SanjaySELECT DISTINCT PERIOD_NO, ITEM_CODE, ITEM_NAME, SUM(CASE WHEN LEVEL_TYPE IN 'SUB ZONE' THEN WD_FORECAST_QTY_BU / CNV / ML ELSE 0 END)TOT_FRCST FROM SHEET_HEAD, SHEET_DETAIL, ITEM_DETAIL WHERE WH_SYS_ID = WD_WH_SYS_ID AND ITEM_CODE = WD_ITEM_CODE(+) AND PERIOD_NO BETWEEN :PERIOD1 AND :PERIOD2 AND WH_REVISION_NO = 0 AND WH_LEVEL_CODE NOT IN (SELECT WH_LEVEL_CODE FROM SHEET_HEAD WHERE WH_REVISION_NO = 1) GROUP BY ITEM_CODE, ITEM_NAME, WH_PERIOD_NO
Hello
with speed suggest it would be always be expirement with indexing on parameters, after that first scans all what is currently happening in what concerns analyses of full table etc. which are "more expensive."
Level of the specific actions on your code, that what follows comes out too expensive; -
AND WH_LEVEL_CODE NOT IN (SELECT WH_LEVEL_CODE FROM SHEET_HEAD WHERE WH_REVISION_NO = 1)
Here, I would see if you can rewrite, perhaps with a left join / auto join to achieve the same ends, compare the timings, you might be surprised.

Help - run the extended CO query?
Read the many threads on the topic prior to this announcement, but im still stuck.
I extended a sowing controller, to display text msgStyle seeded as a link under certain conditions.
I want to take is:
If (condition true) {//set the text msg destination uri} otherwise do nothing
To implement the condition, I have to make a request to check if this value exists in the table. I have not any Vo attached to achieve this.
I could create a custom VO and attach it to AM programaticaly? One last thing - AM attached to this seeded page is am root.
I read that AM root should not be extended.
How can I achieve this?Hello
For this, you can use dynamic VO, create VO, and run the query.
Kind regards

Number to reach the desired with query result...
Here some pseudocode tables and data to show my problem:
Desired output of tableCREATE TABLE temp (name_home varchar2(25), name_away varchar2(25), id integer); INSERT INTO temp VALUES ('a','b',1,1); INSERT INTO temp VALUES ('c','a',1,3); INSERT INTO temp VALUES ('e','a',1,4); INSERT INTO temp VALUES ('c','a',1,6); INSERT INTO temp VALUES ('d','e',1,5); INSERT INTO temp VALUES ('b','a',1,7);
NOTENAME_HOME NAME_AWAY ID SEQ a b 1 1 b a 1 7 c a 1 3 c a 1 6 e a 1 4 d e 1 5
My table contains millions or lines like this, idea would be a solution that would be enough for a table containing millions of combos like those above.
I want to display the data with the following by order:
(1) records where any combination of a value of data in "name_home" and "name_away" appears more than one time first (record e.i. with seq 1.7)
(2) sequence number CSA
So, for seq 1 and 7, it does not matter to me that 'a' and 'b' switch between name_home and name_away, they must appear first because a combo of a and b in the same record appears more than once and the number of seq of one of the files is smaller than any of the seq in the accounts rendered by 'c' and 'a '. I hope that makes sense.
Published by: user652714 on November 17, 2010 16:04Fixed, when I read until the end :)
select t.*, count(*) over(partition by greatest(name_home,name_away),least(name_away,name_home)) cnt, first_value(seq) over(partition by greatest(name_home,name_away),least(name_away,name_home) order by seq) min_seq from temp t order by cnt desc,min_seq asc
