• Get multiple values in a select statement in a variable to a procedure

  Hello

  I'm trying to craete a procedure where the entry of the procedure will be a similar string "a, b, c, d" and output the values of a table that matches the value separated by commas of in sting.

  For this.

  create table test (varchar2 (10)) nm;

  Insert test values ('a');

  Insert test values ('b');

  Insert test values ('c');

  Insert test values (');

  Select * from test;

  NM

  ------

  one

  b

  c

  d

  Now I'm doing a procedure where the parameter will be the column values NM of TEST table in a string separated by commas like "a, b, c, d, x, l" there could be false values also.

  The procedure will return only the values that are adapted with column NM from the TEST table for this I created this procedure.

  create or replace procedure p_test (p_nm IN varchar2 / *, THE sys_refcursor p_out * /)

  is

  number of l_len;

  l_val varchar2 (10);

  l_val1 varchar2 (10);

  Start

  l_len: = length (p_nm);

  -dbms_output.put_line (l_len);

  Start

  because me in 1.l_len

  loop

  Select REGEXP_SUBSTR (p_nm, ' ([^,] *)(,|$)', 1, I, NULL, 1) in double l_val;

  -dbms_output.put_line (l_val);

  -Open p_out for

  Select * into l_val1 of test where nm = l_val;

  dbms_output.put_line (l_val1);

  output when l_len is null;

  end loop;

  exception

  When no_data_found then

  null;

  end;

  exception

  while others then

  dbms_output.put_line (' error reason :'||) SQLERRM |' :'|| error code SQLCODE);

  end;

  EXECUTE p_test ('a, b, c, d, q, w');

  OUTPUT-

  one

  b

  c

  d

  This procedure gives me out as I need, but I need to get this in a variable which should be OUT the parameter of this procedure will be called by the JAVA for our application.

  As I already tried to use the refcursor (see the commented part), but it gives me no output during a call there.

  Its a call to this procedure when I use the refcursor (removing comments).

  declare

  l_out sys_refcursor;

  l_val varchar2 (20);

  l_str varchar2 (20): = 'a, b, c, d;

  Start

  p_test (l_str, l_out);

  loop

  extract the l_out in l_val;

  dbms_output.put_line (l_val);

  dbms_output.put_line ('a');

  When the output l_out % notfound;

  end loop;

  end;

  So here I am stuck with that, how to get the result of multiple or I'm missing something here and if there is a better approach to this requirement as I come with that so I'm sharing it here.

  OR if someone can tell me what is the problem with this package-

  create or replace package p_test_api

  is

  type t_rec is rendered (name varchar2 (200));

  type t_tab is table of index by pls_integer t_rec;

  procedure p_pest_proc (p_nm in varchar2, p_out to t_tab);

  end p_test_api;

  procedure p_pest_proc (p_nm in varchar2, p_out to t_tab)

  is

  Start

  l_len: = length (p_nm);

  Start

  because me in 1.l_len

  loop

  Select REGEXP_SUBSTR (p_nm, ' ([^,] *)(,|$)', 1, I, NULL, 1) in double l_val;

  Select * bulk collect into p_out test where nm = l_val;

  output when l_len is null;

  end loop;

  exception

  null;

  end;

  exception

  while others then

  dbms_output.put_line (' error reason :'||) SQLERRM |' :'|| error code SQLCODE);

  end p_pest_proc;

  end p_test_api;

  CALL THIS PACKAGE-

  declare

  l_out p_test_api.t_tab;

  l_str varchar2 (20): = 'a, b, c, d;

  Start

  P_TEST_API. P_PEST_PROC (l_str, l_out);

  dbms_output.put_line ('b');

  because me in 1.l_out.count

  loop

  dbms_output.put_line ('a');

  dbms_output.put_line (l_out (i). (Name)

  dbms_output.put_line ('a');

  When the output l_out.count = 0;

  end loop;

  dbms_output.put_line ('a');

  end;

  It won't loop

  Thank you

  First of all, get rid of it WHEN OTHERS like William already noted. If you do not want to use the collections:

  SQL > create or replace
  function f_test () 2
  3 p_nm varchar2
  4                  )
  5 return varchar2
  6 is
  v_result 7 varchar2 (4000);
  Start 8
  9. Select listagg (nm, ',') within the Group (nm control)
  10 in v_result
  11 test
  where the 12 «,» | p_nm | ',' like '%', | NM | ',%';
  13 return v_result;
  14 end;
  15.

  The function is created.

  SQL > start
  2 dbms_output.put_line (f_test ('a, b, c, d, x, w'));
  3 end;
  4.
  a, b, c and d

  PL/SQL procedure successfully completed.

• How to 'use the tool of value' default tool?

  I recently upgraded from LabView LabView 8.6 8.2 and now the 'exploit value Tool' is the "Position/size/Select Tool" by default.  Is it possible that I can make the tool "carrying value" of the default tool?

  Thank you

  Kevin

  EDIT: deleted my original post, it was incorrect.

  Try the auto tools as suggested by smercurio.  Hold down SHIFT while the automatic selection of tools is active will give you the second-most-useful for this moment; When you move to a control, you will get the position/size/select.

• How to use the 'Get Shared Variable list' VI on a target RT?

  Hello

  I would like to browse all variables shared in a library hosted on my CompactRIO programmatically. I dropped the 'Get Shared Variable list' VI in my VI in real time, but when I tried deploying, LabVIEW says

  Deployment PRC_GetVarList.viPRC_GetVarList.vi loaded with errors on the target and was closed.
  LabVIEW: Unable to load the shared library dscProc.dll:ni_lvdsc_process_GetTagListEnd:C. ensure that the library is present on the target of RT. MAX allows you to install software from OR or FTP to transfer custom RT target libraries.
  LabVIEW: Unable to load the shared library dscProc.dll:ni_lvdsc_process_GetTagListBegin:C. ensure that the library is present on the target of RT. MAX allows you to install software from OR or FTP to transfer custom RT target libraries.

  I watched the wizard of the MAX software, but cannot find the DSC-based modules. Where should I look?

  Thank you!

  Hello

  The palette of DSC is not supported on the screws in real-time and will lead to errors when they are deployed.  Unfortunately, to have a successful build you will need to modify your application and remove the screws from the palette of DSC on your target of RT.

  I have 7 microphones where I take the RMS value.  They are physically located in a line, and I would like to draw their values against their positions.  How can I think.  I guess I'll need to use the XY plot, but I don't know how to turn the 7 signals into a single table and how to create a table of constants for the positions.

  I think that I have, there are however a large number of conversions.  You see somehow I could simplify this, or is it as simple as I'm going to?  I have included my file to the post.

• Cannot get 'IN' text field with multiple values.

  I have a text field (P11_SERIAL_NUMBERS) someone would use to enter multiple values (i.e. of the serial numbers). I tested various methods but can't seem to get anything working. I used values such as ' 12929', '19191' or ('11919', ' 19192 ', ' 1111') or 12121,121333.»
  
  I have to analyze this area after the entrance is and update P11_SERIAL_NUMBER to something like ("121212 ', 121211', '292929'). The report is a SQL query returning the body of a PL/SQL function. I build the query in an anonymous block to something like the following:
  
  SELECT apex_item.checkbox (1, instance_number) Ins,.
  apex_item. Text(2,i.instance_number) instance_number.
  apex_item. Text(3,i.item_number) item_number.
  description of the apex_item. Text(4,i.Description),
  Serial_number apex_item. Text(5,i.serial_number),
  i.party_name,
  i.status_name
  Cycsi_item_details_v I have
  WHERE i.item_number IN (SELECT v.item_number FROM cycsi_installed_base_v WHERE v.serial_number = i.serial_number v)
  AND i.item_number AS NVL ('%' |') XLA' | ' %','%')
  AND NOT EXISTS (SELECT d.item_serial_number FROM cy_fco_d, d WHERE d.fco_id = 2803 AND d.item_serial_number = i.serial_number) AND i.serial_number IN ('61763 ', ' 61621');
  
  However, when I enter several values that nothing ever went back to the SUMMIT even though the SQL query returns more rows. I run the application in debug mode and it seems to show the values correctly.
  
  0.11: show report
  0.12: determine the column headings
  0.12: analyze the query such as: TRAFFIC
  0.15: binding: ": P11_MODEL_NUMBER"= "P11_MODEL_NUMBER" value = "XLA"»
  0.16: binding: ": P5_FCO_ID"= "P5_FCO_ID" value = "2803"»
  0.17: binding: ": P11_SERIAL_NUMBERS"= "P11_SERIAL_NUMBERS" value = '(' 61621', ' 61763')""
  0.19: print the column headings
  0.19: loop lines: 15 rows
  No data found
  
  If I add only a serial number at a time as the APEX application returns the line correctly.
  
  
  Does anyone have an idea what I'm doing wrong or what best way to solve this problem?
  Thank you

  Hi John,.

  I just tried a report region based on PL/SQL query encoded using your method to refer to element names in the query string of back:

  declare
     q varchar2(100) := 'select ename, job from emp';
  begin
     if :P2_ENAMES is not null then
          q := q || ' where ename in :P2_ENAMES';
     end if;
  
     wwv_flow.debug('*** Query: ' || q);
  
     return q;
  end;
  

  As I suspected, he did not work for me P2_ENAMES was ('KING') or ('KING', 'SMITH'). I think it's because of the reason for which I gave in my previous post - ApEx passes off the coast of the dynamic execution of SQL string, it does not automatically replace the mention: P2_ENAMES with the value of the element. I don't know how it can work for you.

  If I change the code I proposed:

  declare
     q varchar2(100) := 'select ename, job from emp';
  begin
     if :P2_ENAMES is not null then
          q := q || ' where ename in ' || :P2_ENAMES;
     end if;
  
     wwv_flow.debug('*** Query: ' || q);
  
     return q;
  end;
  

  It works very well if one or several names are specified.

  I took a blow to modify your code for the construction of the query string - does not immediately guarantee, it'll work because I can't test (might be missing a parenthesis or quotation) it but you should get the idea:

  -- start with initial valid query that ApEx can parse to determine column names
  q := 'SELECT apex_item.checkbox(1, instance_number) ins, apex_item.text(2, i.instance_number) instance_number,
               apex_item.text(3, i.item_number) item_number, apex_item.text(4, i.description) description,
               apex_item.text(5, i.serial_number) serial_number, i.party_name, i.status_name
          FROM cycsi_item_details_v i
         WHERE i.item_number IN (SELECT v.item_number
                                   FROM cycsi_installed_base_v v
                                  WHERE v.serial_number = i.serial_number)';
  
  -- add model number condition if specified
  if :P11_MODEL_NUMBER is not null then
     q := q || ' AND i.item_number LIKE ''%' || :P11_MODEL_NUMBER || '''%''';
  end if;
  
  -- add serial numbers condition if specified
  if :P11_SERIAL_NUMBERS is not null then
     q := q || ' AND i.serial_number IN (' || :P11_SERIAL_NUMBERS || ')';
  end if;
  
  -- add FCO id condition if specified
  if :P5_FCO_ID is not null then
     q := q || ' AND NOT EXISTS (SELECT d.item_serial_number
                                   FROM cy_fco_d d
                                  WHERE d.fco_id = ' || :P5_FCO_ID || '
                                    AND d.item_serial_number = i.serial_number)';
  

  I know that has focused on getting this code works, but I would be remiss in my duties if I didn't at least mention the risk of SQL injection. You may already know this, but unless you do a good job to validate the values of the element used in the query, you could open yourself up to a SQL injection attack. For example, imagine what that would be returned if a hacker sharp entered "12345) GOLD (1 = 1" in the field of P11_SERIAL_NUMBERS - you would get all that may or may not be a security problem.

  Hope this helps,
  John

• Set and get the value of the item application in Javascript

  Hello guys,.
  Can you tell me an example how to set and get the value of the application element in Javascript, and how do I check if the value of the point of application is null in Javascript, too. I have read a few replies, but nothing worked (e.g. $x (app_item), $v (app_item), $s (app_item) and so on).
  
  Thanks in advance!

  To get the value of an element, use the following syntax:

    alert("The value of MY_TEST_ITEM is " + $x("MY_TEST_ITEM").value);
  

  to set the value that you have just made

    $x("MY_TEST_ITEM").value="Set to this value";
  

  Keep in mind however that you need to send the page in order so that he could be picked up by APEX - javascript is CLIENT SIDE, ONLY! Either that or use AJAX to put on the side server.

• Using run ODI setting value

  Hi gurus,
  
  I need a variable that will be used to capture a value @ ODI scenario execution
  This value will be used to update a table column.
  When I run the script it must invite for the value of this variable.
  
  What I tried: -.
  Create a variable: v_test
  Data type: alpha-numeric
  Keep a history: last value
  
  Refreshing:
  Schema: Scott
  Select query: select "xyz" of the double
  -actually I don't want no matter what value of any table... I don't need this selection of double
  
  When I run the script->
  It prompts for the value of "v_test", showing the devault value "xyz".
  If I select OK-> it updates the Test_Table as expected.
  .... But when I type in the value at the prompt, what it does not update.
  
  
  Question: -.
  How to use a run setting value during execution of the script... Please advise.

  Hi starak,.

  Try this:

  -Remove the query from the updating tab.
  -In your package, you need a step for the variable to declare mode. You should not have a step in cooling mode.
  -For generating a scenario, mean ODI use the variable as a parameter.

  It will be useful,

• How to get the value of the global element using javascript or ajax!

  Hello!
  
  How can I read at global(point application created in the shared components) using ajax or javascript?
  You can imagine that I need to get the value of this element by function as:
  -----
  Function getText() {var itemVal = $x ('MY_GLOBAL_ITEM') .value;}  Return itemVal; }
  -----
  .. .but I can't do it because it is not made to couse of the page it is global element! so, anyone know no work around to do?
  I know that I can make point page and read the value of that, but not what I really need!
  If I have 100 pages and all pages need to use my function, it would take 100 Articles :) - that's why its no good average!
  
  Please, share your ideas!
  
  THX

  Rafix,

  You must use a little AJAX to retrieve a request element value. Three steps in this solution. Implementation of a callable JavaScript function, creating an application process on the request and call the JavaScript function with dynamic action.

  1 set up a JavaScript function that can be called by:

  This function calls the process of application level which has a visibility of the element of your application and then returns the value of points.

  Edit your page and JavaScript code according to the code in the 'function and Variable global statement' of your page. You can also add to the model page, that you use, but you also have to encapsulate this code in the script tags.

  getAppItem = function(pItemName){
      var get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=GET_APP_ITEM',$v('pStepId'));
      get.addParam('x01',pItemName);
      gReturn = get.get();
      get = null;
      return gReturn;
  }
  

  2. creating an application on request process:

  The application of level process has visibility to your application-level element. It is to retrieve the value of points and it prints the htp buffer. Essentially, this acts as a way to return the values of AJAX calls (the javascript function we set previously);

  go to the shared components > procedures > Create.

  Point process: "We Demand: run this application...". »
  Name: GET_APP_ITEM
  Type: Anonymous PL/SQL block

  declare
     -- get the item name passed into the JavaScript function.
     app_item_name varchar2(30) := apex_application.g_x01;
  begin
      -- print its value to the buffer
      htp.p(v(app_item_name));
  end;
  

  3. call the JavaScript function with dynamic action:

  The function call allows to specify an application-level element name and have its returned value. The trigger event is specific to what you need, but the action must be of type to run JavaScript code. In my case immediately the value of P1_NUMBER to my value of demand points. This code doesn't have to be in a dynamic action, but it helps to stay organized. you could call it from any script tag.

  $s('P1_NUMBER',getAppItem('MY_APP_ITEM'));
  

  See you soon,.

• How to url using NOT IN (NIN) IR filter for multiple values?

  Apex 5.0.1 (but should work for Apex 4.2)

  I want to set a url with an IR filter using the filter NOT IN. For example, to get a filter that says: status not in (3,4)

  To do this, we can use the url IRNIN_STATUS parameter.

  This method works. Problem is how can I set multiple values in the url?

  IRNIN_STATUS:3, 4 will give a filter 'status not in (3) '
