  Adam:

  Define the LOV query as follows

  declare
  l_val varchar2(100) := nvl(apex_application.g_user,'ADAM');
  begin
  return  'select enAME display_value, empno return_value

• LOV query is not valid, a display and a return value is necessary, column n

  Hello
  
  I AM FACING
  

  LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, 
  the first FROM clause in the SQL statement must not belong to the in-line query.

  with two table, I create lov
  
  the tables are
  

  CREATE TABLE  "CRM_SALES_DEPARTMENT" 
     (     "DEPT_ID" NUMBER NOT NULL ENABLE, 
       "CUSTOMER_ID" NUMBER NOT NULL ENABLE, 
       "DEPT_CODE" VARCHAR2(50) NOT NULL ENABLE,

  CREATE TABLE  "CRM_SALES_CUSTOMERS" 
     (     "ID" NUMBER, 
       "CUSTOMER_NAME" VARCHAR2(255), 
       "CUSTOMER_ADDRESS1" VARCHAR2(255), 
        PRIMARY KEY ("ID") ENABLE
     )

  I USE QUARY
  

  select (SELECT CS.CUSTOMER_NAME FROM CRM_SALES_CUSTOMERS CS WHERE CS.ID=SD.CUSTOMER_ID) AD D, SD.CUSTOMER_ID R  
  from CRM_SALES_DEPARTMENT SD where SD.DEPT_CODE=:P16_MARKET 

  But who show me 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.

• Need help with Bind variable in AF LOV query

  Hello
  
  I have a problem with the binding variable, if I use bind variable in the VO LOV query then my result does not come, if he has do not bind variable it works fine and if I use the variable binding in the LOV search option then it works fine but if I hide the bind variable and set the value in the prepareSesstion AM method the LOV does not return any value. I try to return the values that also all values are also coming, but these values are not the attribute query AF setting.
  
  Query is:
  
  Select substr(d.description,0,40) description
  cm_system_users has
  b cm_user_responsibilities,
  cm_responsibility_processes c,
  cm_processes d
  where a.nt_login =: B_NT_LOGIN
  and a.user_id = b.user_id
  and trunc (sysdate) between b.eff_date and nvl (b.exp_date, sysdate + 1)
  and b.RESPONSIBILITY_ID = c.RESPONSIBILITY_ID
  and c.process_type = d.process_type
  and d.enabled_flag = 'Y' order of d.arguments_flag
  
  FOLLOW the method:
  
  CmProcessViewImpl vo = getCmProcessView();
  String nt_login = getUserPrincipalName();
  vo.setNamedWhereClauseParam ("B_NT_LOGIN", nt_login.toUpperCase ());
  vo.executeQuery ();
  
  Can someone help me with this. It is urgent for me.

  It's a bit underdescribed. IIUC, the purpose of the notice is used as a target for a correct view accessor? (Otherwise, you will have to be more explicit about what you mean by "LOV query".

  If I'm right, there are two possibilities:

  (1) you use an instance of VO in a module shared application instance. If so, make sure that your code is in the prepareSession() for the class of application that module if it is dependent on session (as seems to be below), you must make sure that the module of the application instance is shared in the session scope.
  (2) you have based the view accessor directly on the definition of the VO. This creates an anonymous instance of VO; I don't think there is a way to use prepareSession() to set a variable of liaison on such a forum (which will not be created until the accessor is first used). Pourriez be able to shoot with to put a similar code in the view object create() method class, but I've not tested this.

  If your code is in your module class application primary (as opposed to the class for a shared of AOS instance), the problem here is that getCmProcessView() returns the instance of VO data module of this application instance design-time model, which is never used by accessors of the view.

  Also, why do you need to do this in prepareSession() rather than at the level of the accessor to view? I believe you can get the user name (for the view accessor) with the groovy expression

  viewObject.DBTransaction.session.userPrincipalName

  or maybe just

  DBTransaction.session.userPrincipalName

  (despite this DBTransaction involving, it returns the username web app, not the DB user name).

  It is a declarative 100% solution, if you don't count the Groovy expression as not declarative.

  If you are afraid of a user who is running the LOV (somehow) before the value of the bind variable is preparing, just make sure that the binding variable is marked "required."

• How to disable the popup LOV (query based LOV) tabular

  Hello

  I need help. I need to make a line in a table form the read-only AND disable the Popup LOV (LOV based query). As you can see in the code below all rows with a value of "AUD" becomes read-only. Column 5 is a Popup LOV (query based LOV), and must have become read only AND disabled also. Currently, the code performs the lines = "AUD" read-only, but the user can still click on the Popup LOV this line and select a value from the list, then updates the row.

  All solutions?

  function makeRowReadOnly() {}
  {$('select[name="f06"]').each (function ()}
  var row_val = $(this) .val ();
  ROW_ID var = $(this).attr('id').substr (4);
  If (row_val is "AUD")
  {
  $("#f02_"_+_row_id).attr ("readonly", true) .addClass ('row_item_disabled');
  $("#f03_"_+_row_id).attr ("readonly", true) .addClass ('row_item_disabled');
  $("#f04_"_+_row_id).attr ("readonly", true) .addClass ('row_item_disabled');
  $("#f05_"_+_row_id).attr ("readonly", true) .addClass ('row_item_disabled');

  Hi dekoke_i,

  I tried this on my local instance of APEX 4.2:

  function makeRowReadOnly() {
  $('select[name="f06"]').each(function() {
  var row_val = $(this).val();
  var row_id = $(this).attr('id').substr(4);
  if (row_val == 'AUD ')

      $("#f04_" + row_id).attr("readonly", true).addClass('row_item_disabled');
      $("#f05_" + row_id).attr("readonly", true).addClass('row_item_disabled');
      //make the popup-lov button readonly
      $('#f05_' + row_id).closest('tr').find('td span.lov a').addClass('row_item_disabled').unbind('click');
      $("#f06_" + row_id).attr("readonly", true).addClass('row_item_disabled');

• Enkitec LOV display problems.

  Hi all

  Using newer version of Enkitec LOV.

  https://Apex.Oracle.com/pls/Apex/f?p=4550:1

  Workspace: hanamike

  User name: test

  Password: test

  Application: Test LOV

  

  

  Problems encountered:

  1 Select the item (P1_EMPNO) still a Virgin after selecting the folder even if the session state has been defined using the da

  2 cannot search, example if I just type BL LOV, always search field empty and open return all records of data.

  3. also unable to see the application EK_ML_SEARCH in the State of Session preceding the point.

  Came across the thread below:

  Modal Enkitec LOV refreshment value on screen during the update programmatically

  where Dan mentioned using the:

  1. $s ('PX_ITEM_NAME' 'returnvalue' 'displayvalue',); 
  2. enkitec.modal_lov.jQuery ('#PX_ITEM_NAME') .enkitec_modal_lov ("setValuesByReturn" "returnvalue");

  
  

  but do not know how to apply the above.

  Tried $s ('P1_EMPNO', $v ('P1_EMPNO') in vain.

  
  

  The other columns column mapping works very well.

  
  

  Thanks in advance.

  Zack
  

  Hi Zack, looks like you want to see EMPNO designating the LOV, correct?

  According to me, which caused "trouble" is the 'Display, return, & Default sort Columns(Value Required)' field and you want to settle for other columns assignments.

  By default, the field "Display, return, & default sort columns (high-grade)" allows you to specify the column in which you want to display on the screen after selecting (in your case 1 for EMPNO) and allows you to specify which column to save on the DB (in your case also 1 for EMPNO).  So, I spent it to 1.1

  Once this is done, it is not supposed yo have EMPNO mapped the area of the 'column Element '. & Mapping (s)  This field is for OTHER items that are not your LOV point.

  I hope this makes sense now.

  I also put the DA never run.  It is not at all necessary.

  Let me know if I did not understand what you want to accomplish.

  Thank you

  However, change in the body of a function that returns a SQL query and it is allowed on two pages:

  And the SQL of origin is recognized as a local of LOV definition to edit the Page item (page 4311).

  Hello

  I filed bug # 13520001 to change the checking logic of the wizard named LOV to use the same controls that we do on "Edit Item Page" (4311).

  Kind regards

  How to get query "LOV" i.e. requisition approval path, LOV name is 'APPROVAL_PATH '. How to get this LOV query?

  You can get the query by referring to (how to determine table and the name of the column to a field in a form in 11i [259722.1 ID]).

  Or, you could activate the trace and generate the TKPROF file and this will display the exact query used by the form - FAQ: Techniques of common tracing in the Oracle Applications 11i/R12 [296559.1 ID]

  Or, open the form using the Forms Designer and get the code.

• LOV query fails, but works in SQL commands

  I am trying to create a type with semi-automatic item text field, but the query I fill in the definition of LOV returns an error:

  Impossible to analyze the query SQL LOV!

  ORA-00942: table or view does not exist

  Although when I try the same query in the form of SQL commands, it works without any problem. No idea what I am doing wrong?

  The query is as follows, where v_prt_gem_t is a view and prt_gem is a table.

  SELECT
        PG.POST_CODE||' '||PT.NAAM
  FROM
        V_PRT_GEM_T PT

  It is likely that CERTAIN privileges on one or two tables/views used are granted for the scheme of the analysis of the application through a role, not directly to the schema. Role-based privileges will be observed in the workshop of SQL in the latest versions of database, but not for running applications. See (YABAOAE) yet another Blog about Oracle Application Express: Application Express and SQL Analysis for detailed information.

  That's why you always have to give the full APEX and the database version numbers when you ask a question: implementations and features change over time. If we know exactly which versions are used so we can determine what behavior is expected, and what bugs exist or have been corrected...

• Creation of a where clause clause in the LOV query box

  Hi guys is any able to help me with this one

  I have a page in my application where there down LOV down now values this menu drop-down comes from a table that looks like this

  users_for _form_TBL

  E_MAIL	Name of the vendor
  [email protected]	Oracle
  [email protected]	SAP
  [email protected]	IBM
  [email protected]	Oracle
  [email protected]	Intergraph

  So my syntax for the LOV I mentioned looks like this

  Select PROVIDER as display_value, SELLER as return_value

  of form_user_tab where email =: APP_USER

  order by 1;

  
  

  so if [email protected] connects to the application and to make a selection on the LOV it would only show suppliers compared to his E_MAIL like oracle, sap, IBM , and then he clicks the submit button on the page then the seller that he chose is inserted into another table. What I did on the table of insertion has been to create a trigger that after inserting a seller the trigger inserts a 1 in a column called assessed.

  What I did after that is add a select statement in the where clause of the LOV so that she would check in the table insert if this seller had been chosen before and not show them again to be selected my syntax, the second time around in the SQL query box has been

  Select PROVIDER as display_value, SELLER as return_value

  to users_for _form_TBL where email =: APP_USER

  and (select "seller", "ASSESSD' of _tbl inserted is null);

  order by 1;

  But im getting an error of ideas guys. Thank you

  hay man thanks for your response really using the syntax is

  order by 1;

  im still get and error is the where the clause allowed in the second select statement

  He still has basic syntax errors. You posted 4 different "table names" whose only in the first query is valid so far. That can not see your database, I don't know what really is the name of these tables, and to what extent these is wrong helps your problem.

  I can tell that you are looking for:

  select
      u.vendor display_value
    , u.vendor return_value
  from
      users_for_form_tbl u
  where
      u.e_mail = :app_user
  and not exists (select null from inserted_tbl_imp i where u.vendor = i.vendor)
  order by
      u.vendor
  

  but the table names could be something else...

• Eurotherm EPower controller: query problem

  Hello

  I have a problem with communicating with a controller Eurotherm EPower (with 4 units) by OPC server.

  I use:

  -LV 8.5.1

  -iTools OPC Server 7.50 with a number of product formed the social reason (active license)

  -EPower Firmware v3.01

  Communication between LV and OPC server is made by "DataSocket write" and "Read DataSocket".

  I can write => values without problem I only write Main.SP on the evolution of events user and everything's fine.

  But on reading, I would like to read Meas.I Meas.P, Meas.V, continuous for each unit (up to 12 url request)

  The first reading is ok, so I have values, the url are ok. But after that, it is impossible to put in a loop-online no error, (status = 0 on LV and OPC Server) but the values are not updated with the following query.

  I tried to play with the option "wait for updated value", but without success.

  The only way I've found is to open the interface for server, the device, right click and select "Synchronize Active device". But this option is only a shot and very long because, I guess, he gets everything in the device...

  Another point: it works perfectly with the Engineering Studio, commonly called iTools-iTools. It is a client of the OPC server on my application.

  Another point on the other: when I run my application is the ID_EPower.exe in the list of Windows processes and consume resources (0 or 1%) so he lives.

  Complete, with one hour, I thank them but not way with Eurotherm hotline.

  My question is: Y at - it a particular way to obtain ongoing measures such as sending a query each time or a general property to get updated data?

  I used to cruise control disc from the same manufacturer with no problem and no need to send a request to get the values, but here it is perhaps a different case.

  List of requested URL:

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.V

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.I

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.1.MEAs.P

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.V

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.I

  OPC:/Eurotherm.ModbusServer.1/CLA_Gradateurs.192-168-1-222-502-ID001-ePower.network.2.MEAs.P

  ... Ditto for network 3 and 4

  I joined the part of the code that is dedicated for the reading of values, but it is not really helpful because I think that my method of reading is correct (data arrive but are never updated) is a 'lack' of command to request that the server acquires new data or a bug with the LV-iTools OPC server interface...

  For LabViewers advanced, I know that my attached code is not optimized and not the smartest, but keep cool, I do not need crazy performance

  Any suggestion?

  So, I was not on the spot for the tests, but now it's ok.

  Several series shares have been made to the walkthrough to the problem, but it's hard to know if all were beneficial:

  -An update of software Eurotherm: 7.50 to 7.68

  -An update of the firmware EPower: 3.01 to 3.03

  - and probably the main cause of the problem: change the cable through a cross-wired (we thought it was, but not in reality...). But even if it is the main cause: how it was possible to receive data by forcing the update in the OPC server... strange.

  Thanks for your help.

• in LOV query to get the Responsibility_id using profile... but when I switch to another responsibility always the LOV shows the previous values of RESP.

  Hello

  I have the choice of Message box, in which I'll show the inventory list organizations are assigned to responsibility. I just the following query in the query of LOV...

  Select hou.NAME separate organization_name, mp.organization_id

  of mtl_parameters mp

  , hr_organization_units hou

  oa org_access

  where mp.organization_id = hou .organization_id

  and hou.organization_id = oa.organization_id

  and oa.responsibility_id = fnd_profile.value ('RESP_ID')

  organization_id asc order

  But first let's say after the OA Core bounce if I open a responsibility which is to have access to 5 associations of the inventory, and then in the message of choice is showing correctly... But when I go to another responsibility that is to have access to a single inventory, always the choice of Message body shows the previous inventory 5 Orgs who is to have access to the prior responsibility.

  Pointers on this?

  Thank you

• Implementation OFA LOV

  Hello

  My page to update the FPÖ has 2 columns responsibility (RESP) name, key RESP.

  I joined a RespNameLOV LOV to the field name RESP and not created mappings for a name and key RESP RESP, no lov attached to the RESP key field.

  So when I select a value in the name of RESP using LOV, key RESP must get filled automatically.

  This does not work very well.

  When I click the button of the field name of the RESP and research responsibilities LOV that no values are returned, however when I erase the name of RESP and RESP key fields on the update page and click the LOV and appropriate research results are returned.

  What is - that I missing here or is it how works the LOV in the OPS?

  Please see attached for the components of the page file.

  Query RespNameLO VO:

  Select responsibility_name, fnd_responsibility fr, fnd_responsibility_tl frt responsibility_key

  where fr.responsibility_id = frt.responsibility_id

  and frt.language = 'en '.

  and fr.end_date is null

  Thank you

  If there is a value in the field that will be used as a criterion for the LOV. (which means that will add a dynamic whereclause based on the value.)

  In your case, you don't need to have this criteria for the RespKeyMap object. Try removing the CriteriaItem of the KepMap and see if it makes a difference.

  See you soon
