How to get all minimum values for a table of valuable documents?

I need to get the list of records of the minimum value for a table that has the structure and the data below
create table emp (name varchar2(50),org varchar2(50),desig varchar2(50),salary number(10),year number(10));

insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',3000,2005);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',4000,2007);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',7000,2007);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',7000,2008);
insert into emp (name,org,desig,salary,year) values ('emp1','org1','mgr',7000,2010);
commit;


SELECT e.name,e.org,e.desig,min(e.year) FROM emp e,(
SELECT e1.name,e1.org,e1.desig,e1.salary FROM emp e1
GROUP BY (e1.name,e1.org,e1.desig,e1.salary)
HAVING COUNT(*) >1) min_query
WHERE min_query.name = e.name AND min_query.org = e.org AND min_query.desig =e.desig
AND min_query.salary = e.salary
group by (e.name,e.org,e.desig);
With the above query, I can get the year less value where the EMP has maximum salary. It returns a single record. But I want all the records that are minimal compared to the value of the year max

Power required
emp1     org1     mgr     7000     2008
emp1     org1     mgr     7000     2007
Please help me with this...

Hello

Aggregate functions reduce the result set with one row per group.
Almost all of the aggregate functions are homologous analytics that can give the same results without restricting the result set. Since you want the output to contain several lines per group, then the analytic functions are probably better for you.

Here's one way:

WITH      got_analytics     AS
(
     SELECT     name, org, desig, salary, year
     ,     MAX (salary)  OVER ( PARTITION BY  name, org, desig)          AS max_salARY
     ,     ROW_NUMBER () OVER ( PARTITION BY  name, org, desig, salary
                                ORDER BY        year  DESC
                       )                              AS year_num
     FROM    emp
)
SELECT     name, org, desig, salary, year
FROM     got_analytics
WHERE     salary          = max_salary
AND     year_num     > 1
;

  • How to get a magic number for any table that returns more than 32 k?

    I'm in a unique situation where in I try to extract the values of the multiple tables and to publish as XML output. The problem is based on the condition of a few tables can retrieve more than 32 KB and less than 32 KB of data. Less than 32KB is not a problem, as the generation of XML is smooth. The minute he reached more than 32 k, it generates a runtime error. I was wondering if there is a way to make sure that the minute results of the query is greater than 32 KB, it must break say - if results is 35KO, so should I break this result 32 KB and 3 KB. Once then pass these data to appear as XML output. Again, it is not just for a table, but all the tables which are called in the function.

    Is it possible? I'm unable to get ideas, or did I do something so complex from the point of view of production support. If you'd be grateful if someone can guide me on this.

    The way it is, is the following:
    I have a table named ctn_pub_cntl


    CREATE TABLE CTNAPP.ctn_pub_cntl 
    (ctn_pub_cntl_id          NUMBER(18)
    ,table_name                  VARCHAR2(50)

                        ;
    

    The minute I comment

    ||  ' AND rownum < 16' ;


    It generates an error because this query returns about 600 lines and all these lines must be published in XML format and the tragedy, is that it is a C program between institutions i.e. C calls my functions of packged and then will do all the processing. This will return the results to the C program. Then obviously C does not recognize the CLOB and somewhere in the process, I convert to VARCHAR or CLOB CLOB, I have to use VARCHAR as a return type. That's my challenge.


    Someone who can help me find the number required of magic and also a brief knows how, I understand that. Thanks in advance.

    Function getXMLData() generates a canonical XML document out of the table that is passed as a parameter.

    Function built getCTNData() code XML "PUBLISH", the document using SQL/XML functions, the getXMLData() call in the process and returns the content serialized as a CLOB.

  • How to get ALL of the 'real' database table in apps/apps

    Hi all

    EBS R12.2

    OEL 6

    I create tables derived from drawing apps and custom drawing.

    When I connect to apps/apps, there are a lot of objects, synonyms, views that point to other tables, synonyms, views of another schema as AP, AR, GL, etc..

    What is confusing is a view contains a table attached, then it is created with a synonym of an another synonyms joined another scheme.

    How can I get the list of actual tables being accessed from these apps objects?

    I would also like to count the lines of ALL the actual tables and get their real value.

  • How to get all the records for each group - double

    Hi all

    I have developed customized reports, I have a three for each group, the first group is for PO number and the second is for line number Po and the third is for activity ID.


    Today the third group is based on the activity ID.

    Some time the activity id is unique and other data are different. If at this time its settlement only one record.

    For example

    Date of activity Id

    1 25 - Jan

    1 26 - Jan



    Its single record display.

    Can someone tell me how to avoid this separate for each group.

    Thanks and greetings

    In SQL * Plus, you can use the PAUSE command

    SQL> ed

      1  select deptno, ename
      2    from emp

  • How to set the minimum value for the division based on the metric of Super?

    I want to create the Super metrics include:

    (Data reading KB store / writing KB) * 100

    To get an understanding of the relationship between reads and writes.   However, this equation will always climb 0 if a number is 0.

    Is there a way to say "if read = 0 then read = 1 ' so that the equation will not evaluate to 0?

    Thank you

    -MattG

    There is no 'if' statement... but thought that you can add a (metric + 0.0001) which should not be 0

  • How to return all the values in the table in AE/w alert() message script?

    Here is my code:

    {
    var selectedItem = app.project.activeItem;
    var thisProj = app.project;
    var layerList = new Array();
    var compList = new Array();
    
    function listLayers(compNum){
      for(i=1;i<=compNum.numLayers;i++){
      layerList.push(compNum.layer(i).name);
      }
    }
    
    function listComps(){
      for(i=1;i<=thisProj.numItems;i++){
            if(thisProj.item(i) instanceof CompItem){
            compList.push(thisProj.item(i).name);
            if(thisProj.item(i).numLayers>0){
            listLayers(thisProj.item(i));
            }
            }
      }
    }
    
    listComps();
    alert("here's a list of all comp names:" + compList);
    }
    

    When I run it with ExtendScript tool within EI, the alert() will cause this error message:

    invalid numeric result (division by zero?)

    It works fine if I don't write on one of the elements of the array. For example:

    alert("blablabla"+complist[1];
    

    Or if I leave aside the ' + '.

    How can I write on the Board or even several bays at the same alert() and adding text between the two?

    Thanks in advance,

    Fynn

    Try this way:

    Alert ("here is a list of all layout names:" + compList.toString ());

  • JDeveloper 11 g: how to get all the rows in a table of database application

    Hi all!

    I'm developing an application with JDeveloper 11 g, as the subject of the show.
    So I'm suppose to use some of the data that are in the database table.
    So, I got the View object, which is where I want to take data, to the datamodel.
    And after that, I use the following line in my serviceClass.java:
    public String method(){
            String truc = null;
            getViewName().setRangeSize(-1);
            getViewName().setRangeStart(0);
            getViewName().executeQuery();
    
    //I do my treatment here
    return truc
    }
    When the application is run, it stop just before the line "getViewName ().setRangeSize(-1);
    So, I think that it is the point of locking.
    Someone can help me.

    Thank you to

    Nystan

    Hello

    check if 'viewObjectName' is the name that he presents in the ApplicationModule data model. This isn't the ViewObject name you are after the instance of the object View, which is a difference

  • Take the minimum value for table data

    I'm storing test data in a table, with the hope that I can output the minimum value of the data. So far, I have used the table of max/min but can't make it work how I want. The test runs continuously in a loop of the holder. I get the minimum values in the table, but I would like to change the number of samples that the table contains, before it generates a minimum. The other option is that I run the test for a period of time (e.g. 3 seconds) and the table stores the data for this time then output 1 minimum value for the entire period.

    My current configuration VI is attached.

    Very appreciated

    Chris

    The size of the array in your VI is determined by the number of samples that you collect in your DAQ assistant, who is now 100 samples.  Never more, never less.

    How many samples do you want before you determine the minimum?

    Maybe what you really want to do is to build the table in the while loop and store it in a shift register, and when the loop has repeated enough times, then you take the minimum of built table.

  • All they can do is go on the Internet Explore. So my question is how to get features of office for a guest user?

    Hi, I want to let my friend use my laptop and I need to set up a guest account. The problem is that when I did it, we cannot access Office so that the person cannot create any word or excel files, etc. All they can do is go on the Internet Explore. So my question is how to get features of office for a guest user?

    Don't add a guest account, add another standard user if you want another user to access programs as well.

  • DVT:pivotFilterBar - how to get the selected values of the filter

    Hi all

    I have a question: how to get the selected values from the pivot table filter bar programmatically?

    I tried to use
    pivotTable.getDataModel().getDataAccess().getValueQDR(startRow, startCol, DataAccess.QDR_WITH_PAGE);
    but to the edge of the side DATA INCORRECTESdeclarations page, it seems that it will return the cached values.

    Environment: JDev 11.1.1.3.0 without tasks.

    Thank you
    Miroslaw

    Hello

    You can retrieve the value selected in the PivotFilterBar through the PivotFilterBar model, instead of dataaccess:

    Download the template of the bar pivot filter instance
    QueryDescriptior queryDescriptor = (QueryDescriptor) pivotFilterBar.getValue ();

    retrieve a list of criterion, each of them is used to fill each lov in the pivot filter bar
    ConjunctionCriterion conjunctionCriterion = queryDescriptor.getConjunctionCriterion ();
    List criterionList = conjunctionCriterion.getCriterionList ();
    for (int i = 0; i)<_criterionList.size(); i++)="">
    AttributeCriterion = (AttributeCriterion) criterionList.get (i) criterion.

    _selected is the currently selected value
    Selected object = criterion.getValues () .get (0);

    System.out.println (_selected);
    }

    Hope that helps,
    Chadwick

  • How to get an RMA number for a money-back guarantee?

    September 13, 2014

    Hi all

    I'm trying to figure out how to get an RMA number for a warranty for my iOmega ix2 return. I checked my warranty and it's good for another year. The Lenovo Web site sent me round and round, never really getting to any kind of page which will allow me to enter my serial number and other data of warranty.

    I would like to call or chat but it's Saturday, and these options do not appear to be taken over the weekend.

    Someone has a direct link to the page of Lenovo/iOmega NAS support guaranteed returns?

    Thank you in advance.

    Best,

    Jeff
