Join the query in a dynamic list of values query

I have a join query in a dynamic list of values query. The value does not return a value of text, but rather the value of the ID.

Is it possible to use a join query in a dynamic list of values query?

For example... in the query below, I expect to see ename in the drop-down list, but I see class_emp_id.

Select b.ename d, a.class_emp_id r
of class_emp a, b of the emp
where a.class_cat_id =: CURR_CLASS_CAT_ID
and a.emp_id = b.emp_id
order by 1

Thank you
Reid

Hey Reid,

The structure of the pairings/value of the item is incorrect - it should be: item1, item2, etc.: value1, value2, etc, so:

' f ? p = & APP_ID.: 50: & SESSION. ": P50_LP_ID, P50_LP_NAME, CURR_CLASS_CAT_ID: #LP_ID #, #LP_NAME #, #CLASS_CAT_ID #"

I guess that CURR_CLASS_CAT_ID does not use the prefix P50_?

  • creating a dynamic list of values

    Hello

    While I am trying to create a dynamic list of values on a table (table1) with h_id columns, the head_foot and the header. I gave the query to create the dynamic values as list

    "1 error has occurred."

    LOV query is not valid, a display and a return value is needed, the column names must be different. If your query contains a query online, the first CLAUSE in the SQL statement must not belong to the query online. »


    Can someone please suggest me if am wrong.


    Thanks in advance

    Hello

    I suggest that you check the permissions of your application of the analysis of schema has on your g.fw_header_footer table.

    It is a mistake to mislead, but I've just reproduced the same problem trying to select from a table that I didn't have SELECT permission.

  • Join the query - confused behavior

    Hello.. I need to make a join on four tables and select one data tables. The query is as below,

    SELECT THE VIRTUAL MACHINE. SEGMENT, VM.CA, VM. PR, VM. BP, VM. TERM_ID, VM. TL v_mlr_cable VM, v_neicode NEI, v_mlr MLR, v_fibre_ntwk_type FIBER WHERE MLR.master_key = 62 AND MLR.dslam_tid = NEI.id AND NEI.type = 'OLT' AND MLR.ntwk_type = FIBRE.id AND MLR.master_key = VM.master_key;

    This query works very well. I want to change the query to have an OR condition by combining certain conditions in the WHERE clause as below,

    SELECT THE VIRTUAL MACHINE. SEGMENT, VM.CA, VM. PR, VM. BP, VM. TERM_ID, VM. TL v_mlr_cable VM, v_neicode NEI, v_mlr MLR, v_fibre_ntwk_type FIBER WHERE MLR.master_key = 62 AND ((MLR.dslam_tid = NEI.id ET NEI.type = 'OLT') or MLR.ntwk_type = FIBRE.id) AND MLR.master_key = VM.master_key;

    This translates into several duplicates of the correct result lines (about 93 272 rows).
    I suspect this is a unwanted Cartesian product.
    I am limited to use a 'different' because my application performs custom, so 'distinct' query analysis is out of the option.

    I struggle to understand the result of this query. You can help... ! Thanks in advance.

    Hello

    Can hide you the SELECT DISTINCT in a subquery, like this:

    SELECT  *
FROM    (
            SELECT DISTINCT  VM.SEGMENT, ...
        );

    or in a view?

    If this is not the case, use GROUP BY. The GROUP BY clause contains all the columns in the SELECT clause.

    You could also re - write the query to use EXISTS or IN, instead of a jon.
    For example:

    SELECT      SEGMENT
,     CA
,     PR
,     BP
,     TERM_ID
,     TL
FROM     v_mlr_cable     vm
WHERE     master_key     = 62
AND     EXISTS (
          SELECT  0
          FROM     v_neicode       NEI
          ,     v_mlr            MLR
          ,      v_fibre_ntwk_type FIBRE
          WHERE     MLR.master_key      = vm.master_key
          AND      (     (     MLR.dslam_tid      = NEI.id
                    AND      NEI.type      = 'OLT'
                    )
               OR      MLR.ntwk_type      = FIBRE.id
               )
            )

    Hello

    I have two tables Employee and EmployeeDetail

    Note: that in the table EmployeeDetail, detail of the employee was inserted not updated therefore for EmployeeID: exiists there are 2 previous entry in the EmployeeDetail table.

    I want to take the latest recordings as

    last disk would probably be more EmployeeDetailID, base on this point, as an easy way:

    Select *

where e.employee_id = ed.employee_id
    And ed.EmployeeDetailID = (select Max(EmployeeDetailID ) from EmployeeDetail ed2 where ed2.employee_id = e.employee_id)

    best solution would be a rank of the analytic function on the partition by but it is more understandable.

    Hi, I'm new to database. I have a question about joining 3 tables, forgive me for my bad English.

    My paintings look like this

    Table 1: person (id, firstname, lastname)
    Table 2: AssignPersonAddress (id, personid, addressid, type)
    Table 3: address (id, phone, street, etc.)

    I need AssignPersonAddress table, because in my data structure, a person may have more than 1 address and address type must be registered (for example: private, work)


    I want to do a select query to the State any person with his private phone and work phone, like this.
    NOBODY | PRIVATE | WORK



    Right now my query looks like this
    select p.name , a1.tel AS Private, a2.tel AS Work
from person p, 
addresse a1 , 
AssignPersonAddress apd1, 
AssignPersonAddress  apd2,

For the page in question, I went to Page rendering-> items, but can not see all items created for this slot table form. Where did I select the item so that I can join the list of values.

    I read the day 2 + Application Express Developer's Guide and followed the example here.

  • Table with list of value to load on another value of the column that is never changed by the user

    Nice day!

    I work with JDeveloper 11.1.2.4.

    I have a Table of the ADF that has 4 lines.  Each row has a column with a unique value.  The plan should include a LOV column in the row show a different list of values based on a single column value.  I have install the list of values, use a display with a variable binding criterion.  When you create the data LOV source, I Specifies the name of a single column for the value of the bind variable.  However, it seems that the LOV changes none selecting different lines.

    Is there a good way to handle this?  I did LOVs of person in charge in the past, but this isn't quite the same as the user can view only the value that depends on the LOV on.

    Any suggestions are greatly appreciated!


    BradW

    Hey, it's always a case of use of the dependent list of values. If the attribute that you bind the bind variable view criteria at part of the view object then the value LOV to be examined accordingly. I did a quick test case and I see my lists filtered by an attribute in line (I used the HR schema and posted employees as candidates managerId. The employee list is filtered so that it only shows the employees in the same Department that the employee I want to put a new managerId on) Frank

  • Create a list of values (Lov) programmatically

    I need to dynamically create the ListOfValues during execution.

    For this, I found a few links, in which it is explained how to create the ViewAccesor and the ListBindingDef which defined the Lov in the model project.

    Andrejus Baranovskis Blog: The ADF for BC and dynamic ADF ADF UI generator

    Binary: Activation for dynamic attributes ViewObject LOVs

    This kind of list of values can be rendered with the component, af:dynamicComponent, but I want to use them with the original component.

    The main problem is that: a dynamic list of values attributes do not have listOfValuesModel in the exposed binding.

    <af:inputListOfValues id="comunidadAutonomaId"
                              popupTitle="Search and Select: #{bindings.ComunidadAutonoma.hints.label}"
                              value="#{bindings.ComunidadAutonoma.inputValue}"
                              label="#{bindings.ComunidadAutonoma.hints.label}"
                              model="#{bindings.ComunidadAutonoma.listOfValuesModel}"
                              required="#{bindings.ComunidadAutonoma.hints.mandatory}"
                              columns="#{bindings.ComunidadAutonoma.hints.displayWidth}"
                              shortDesc="#{bindings.ComunidadAutonoma.hints.tooltip}">
            <f:validator binding="#{bindings.ComunidadAutonoma.validator}"/>
        </af:inputListOfValues>

    Model = "#{Bindings.ComunidadAutonoma.listOfValuesModel}"-> This property is empty in an attribute with a dynamic lov, at the same time, it exists in a standard attribute with lovs. "

    I could check bindings exposed during this attributes are different too.

     <attributeValues IterBinding="ProvinciasIterator" id="ComunidadAutonoma">
      <AttrNames>
        <Item Value="ComunidadAutonoma"/>
      </AttrNames>
    </attributeValues>
    <listOfValues IterBinding="ProvinciasIterator" StaticList="false" Uses="LOV_Nombre" id="Nombre"/>

    To solve it, I thought that I could create the ListOfValuesModel of the ListBindingDef and the ViewAccesor dynamically exposed in a managed Bean, but I don't know how he.

    public class MyBean {


  public MyBean() {
    initListOfValuesModel();
  }


  private ListOfValuesModel listOfValuesModel;


  public ListOfValuesModel getListOfValuesModel() {
    return listOfValuesModel;
  }


  private void initListOfValuesModel() {    
    DCBindingContainer bindings = getBindings();
    JUCtrlValueBinding attrBinding = (JUCtrlValueBinding)bindings.get("myAttrib");
    ViewAttributeDefImpl attr = (ViewAttributeDefImpl) attrBinding.getAttributeDef();
    ViewDefImpl viewDef = attr.getViewDef();
    ArrayList<ListBindingDef> listBindings = viewDef.getListBindingDefs();
    ListBindingDef lbLov = null;
    for (ListBindingDef listBinding : listBindings) {
      if (listBinding.getListVOName().equals(attr.getLOVName())) {
        lbLov = listBinding;
        break;
      }
    } 
    ...
    //listOfValuesModel = ;
  }

    Another solution would be resolved in the code of the ad: dynamicComponent, because it could render the ListOfValues I programmatically add.

  • How to get a prompt to return a list of values based on a prompt

    Hello
    In the link below, I show the chain and the guest of the station.
    The guest of the station must return a list of value based on the value I have insert for string.
    If for example I have insert FS for the Four Seasons chain, what resort it must return only the hotels belonging to four seasons.
    I tried as in the example with a variable, but not worked.
    Any idea?

    Thanks and greetings
    Giuliano

    Hello

    Do you have values for the stations for the value of the selected channel. I assume that you have no station for the selcted string value values. Try to select values of chain of 5 or 10 and then check the value of the station. To force them to work there is no need to define any variable presentation.

    Kind regards

    order of which_month)
    

    The query result is as below
    

    
DISPLAY_MONTH
    

    AUGUST 2012
    SEP 2012
    OCT 2012
    

    Is it possible I can join these two select statement above to generate a comparable result:
    

    
Days of month Phase number Avg
    August 2012 Phase One 8.666
    Sep 2012 Phase One 7.66
    Oct 2012 Phase One 5,66
    August 2012 Phase two 8.666
    Sep 2012 Phase two 7.66
    Oct 2012 Phase two 5,66
    August 2012 Phase three 8.666
    Sep 2012 Phase three 7.66
    Oct 2012 Phase three 5,66
    

    Or
    
Days of month Phase number Avg
    August 2012 Phase One 8.666
    August 2012 Phase two 7.66
    August 2012 Phase three 5,66
    Sep 2012 Phase One 8.666
    Sep 2012 Phase two 7.66
    Sep 2012 Phase three 5,66
    Oct 2012 Phase One 8.666
    Oct 2012 Phase two 7.66
    Oct 2012 Phase three 5,66
    

    And it can be controlled by Phase number or month.
    My other colleague suggested I should use a left outer join, but after having tried many ways, I'm still stuck.
    

    I tried select is
    Select a.display_month, b.* in)
    Select to_char (which_month, 'LUN YYYY') as display_month
    de)
    Select add_months (to_date (' ' August 2012 ', ' MY YYYY' "), rownum-1) which_month
    of object
    where
    rownum < = months_between (to_date (' ' Oct 2012 ', ' MY YYYY' "), add_months (to_date (' ' August 2012", "MY YYYY"), - 1))
    order which_month)) a left outer join
    

    (Select to_char (ph.date_finished, 'MY YYYY') as join_month, ph.phase_number)
    sum ((case
    WHEN ph.date_finished IS NULL or ph.date_finished > last_day (TO_DATE (a.display_month, 'MY YYYY'))
    THEN last_day (TO_DATE (a.display_month, 'MY YYYY'))
    Of OTHER ph.date_finished
    END)
    (-ph.date_started + 1) / count (def.def_id) as avg_days
    Ph phase_membership
    inner join court_engagement this on ph.mpm_eng_id = ce.engagement_id
    join in-house defendant def on ce.defendant_id = def.def_id
    where def.active = 1
    and ph.date_started < = last_day (TO_DATE (a.display_month, 'MY YYYY'))
    and ph.active = 1
    and UPPER (ce.court_name) LIKE '% '.
    To_char (ph.date_finished, 'MY YYYY'), group (phase_number) rollup) b
    On a.display_month = b.join_month
    

    but then I get an error
    SQL error: ORA-00904: "A." "" DISPLAY_MONTH ": invalid identifier
    

    I need to view a report on the APEX with option for people to download at least format CSV.
    Already 1 inteactive report in the page, so I don't think adds another interactive report without using the iframe trick.
    

    If any of you have any ideas, please help.
    

    Thank you very much.

    Hello Ann,.
    

    Frank has done a very good job. I am also impressed.
    

    Is in regard to your correction to his question, the problem is on this replacement you did
    

    last_day(TO_DATE(am.which_month,'MON YYYY'))

    

    AM.which_month is already a date type, and you don't need to convert it to this day.
    Here is the correct way:
    

    last_day(am.which_month)

    

    There are also sometimes with the data you've posted have no line for this month. So I also added a function NVL to display 0 under avg_days for these cases.
    

    Here is my corrected query:
    

    DEFINE startmonth = "Aug 2012";
DEFINE endmonth   = "Oct 2012";
WITH  all_months  AS
(
   SELECT ADD_MONTHS(to_date('&startmonth','MON YYYY'), ROWNUM-1) AS which_month
   ,      ADD_MONTHS(to_date('&startmonth','MON YYYY'), ROWNUM  ) AS next_month
   from all_objects
   where
   rownum <= months_between(to_date('&endmonth','MON YYYY'), add_months(to_date('&startmonth','MON YYYY'), -1))
)
SELECT TO_CHAR (am.which_month, 'Mon YYYY')  AS month
     , ph.phase_number
     , NVL(sum ( (CASE
                 WHEN ph.date_finished IS NULL OR ph.date_finished > last_day(am.which_month)
                 THEN last_day(am.which_month)
                 ELSE ph.date_finished
              END
             ) - ph.date_started + 1
           ) / count(def.def_id), 0) as avg_days
  FROM all_months am
       LEFT OUTER JOIN  a_phase_membership  ph  PARTITION BY (ph.phase_number)
          ON  am.which_month <= ph.date_started
          AND am.next_month  >  ph.date_started
          AND ph.date_started <= last_day(am.which_month)  -- May not be needed
          AND ph.active = 1
       LEFT OUTER JOIN  a_engagement  ce
          ON  ph.mpm_eng_id = ce.engagement_id
          AND ce.court_name IS NOT NULL  -- or something involving LIKE
       LEFT OUTER join  a_defendant     def
          ON  ce.defendant_id = def.def_id
          AND def.active = 1
 GROUP BY ROLLUP(phase_number, am.which_month)
 ORDER BY  am.which_month
        ,  ph.phase_number
;

The output is:
MONTH    PHASE_NUMBER           AVG_DAYS
-------- -------------------- ----------
Aug 2012 PHASE ONE                     0
Aug 2012 PHASE THREE                   0
Aug 2012 PHASE TWO                     0
Sep 2012 PHASE ONE                    12
Sep 2012 PHASE THREE                   1
Sep 2012 PHASE TWO                     9
Oct 2012 PHASE ONE                     8
Oct 2012 PHASE THREE                   0
Oct 2012 PHASE TWO                    14
         PHASE ONE                    11
         PHASE THREE                   1
         PHASE TWO                  11.5
                              9.71428571

    

    I don't know if that's really what you want. In the case check it and let me know.
    

    Kind regards.

    Attribute substitution does not not in the models of dynamic lists
     
			 Hi all
    Dynamic lists were introduced at the APEX 4.1 and they can be used for drop-down menus. I try to use attribute substitution #A01 #... #A10 # in models without success.
    

    Here's a select sample
    

    < pre >
    SELECT the level,
    short_title label,
    ' f ? p = myapp:1:0:MYAPP_ID :'|| target ID,
    'NO' is_current
    NO picture,
    'm'|| Attribute1 to_char (ID)
    FROM MyTable
    START WITH parent_id =: MYAPP_ROOT_ID
    CONNECT BY PRIOR ID = parent_id
    Brothers and SŒURS of ORDER BY seq_in_parent
    < / pre >
    

    and here is a snippet of the model
    

    Model list associated
    

    & lt; class li = & quot; dhtmlMenuItem & quot; & gt; & lt; an id = & quot; #A01 #& quot; href = & quot; #LINK #& quot; & gt; # TEXT #& lt; /a & gt; & lt; /Li & gt;
    

    The substitution is not made. It looks like a bug, but maybe I'm missing something.
    

    Any help would be greatly appreciated.
    

    Regards Garry			 
    Hi Garry,
    

    Given the query you provided, it looks like you're missing two parameters in your query (marked as missing below):
    

     SELECT level,
        short_title label,
        'f?p=myapp:1:0::::MYAPP_ID:'||id target,
        'NO' is_current,
        NULL image,
        NULL image_attribute,                                 <----------- MISSING
        NULL image_alt_attribute,                             <----------- MISSING
        'm'||TO_CHAR(id) attribute1
   FROM mytable
  START WITH parent_id = :MYAPP_ROOT_ID
CONNECT BY PRIOR id = parent_id
  ORDER SIBLINGS BY seq_in_parent

    

    Once you update your application, then if all goes well, you should see the correct replacement of the occurrences of #A01 # in the model of your list with the value returned by the query to youe.
    

    Kind regards
    Hilary
