• What subprogramme should we prefer to return multiple values with OUT parameter?

  Hello

  I worked on the procedures and functions, and aware of their differences. Today I have an interview question that - suppose I don't have return multiple values through a subroutine and I want nor run any what DML within this subprogramme and I want to use this subprogramme in the SQL query. What subprogramme I would prefer - "Operating Mode" or "Function" and why?

  In my view, both can be used in this case, but want to see your views and opinions.

  Kind regards

  In terms of software engineering, if you claim something that you expect to "return" something (a value or values) then you use a function.  If you call something to "do" something, and then you use a procedure.

  THE settings are not good practices in many cases and should not strictly considered "return" of values.  Instead, they are assigned values in the code and generally act as pointers to the original variable/structure that was passed as a parameter (the actual internals of Oracle don't quite do it, but in principle this is what they do).

  A return value (or structure) of a function is basically push in the battery to the point that the RETURN statement is issued, and then the code calling the stack appears to assign it to a variable or placeholder, it should go in.

  If it seems a little difference between procedures and functions to some people, it is recommended to use functions for obtaining values and procedures to do things, in most cases.  It is not just "syntactic sugar", as mentioned above.

• Plugin to point that returns multiple values

  When you create an APEX element that can return multiple values, such as a checkbox, APEX uses the settings of varchar2 p_v01 - p_v200 instead of the p_t01 table settings - p_t200.

  I would like to create a plugin item type that can return multiple values in the same way, so that the session recorded for the item state contains a delimited string of values.  I realize, I could achieve with Javascript and a hidden item, but I really want to a non-Javascript solution.  Is this possible?  If this isn't the case, it would be a nice improvement!

  Hi Tony,.

  Take a look at the level of the parameter p_is_multi_value of the APEX_PLUGIN. GET_INPUT_NAME_FOR_PAGE_ITEM api (http://docs.oracle.com/cd/E37097_01/doc.42/e35127/apex_plugin.htm#AEAPI1254). If you set it to TRUE, you will get one of the p_v01 - p_v200 table settings. It's the same what our box element type calls.

• Return multiple values from a table

  Hi there I'm working on a bit of sql that returns values when they exist in a table.
  The code I have returns the correct value when there is an entry in the tbl_studentmodules table, as soon as there is more than one entry in this table it does display no line at all: (.)
  
  Can someone tell how to return multiple values?
  
  

               select modulename from tbl_modulefeedback
  where 1 = (select count(*) from tbl_studentmodules
         where upper(:APP_USER) = upper(student_id))
  and 1 = (select count(*) from tbl_modulefeedback, tbl_studentmodules
        where tbl_modulefeedback.modulecode = tbl_studentmodules.modulecode)

  Thanks in advance!
  
  Ashleigh

  Try this:

  select modulename
  from tbl_modulefeedback
  where 1 <= (select count(*) from tbl_studentmodules
         where upper(:APP_USER) = upper(student_id))
  and 1 <= (select count(*) from tbl_modulefeedback, tbl_studentmodules
        where tbl_modulefeedback.modulecode = tbl_studentmodules.modulecode)
  

  When you ask questions, please enter CREATE TABLE and INSERT some commands to make it easier to help you.

• Return multiple values from a function in a SELECT statement

  I hope I've provided enough information here. If not, let me know what I'm missing.
  
  I create a view that will combine the information from several tables. Most are pretty simple, but there are a couple of columns in the view that I need to get by running a function within a package. Even if this is quite simple (I have a function named action_date in a package called rp, for example, that I can use to return the date that I need through SOME rp.action_date (sequence_number).
  
  Here is the question: I really need to return several bits of information of the same record (not only action_date, but also action_office, action_value, etc.)-a join of the tables will work not here, as I will explain below. I can, of course, perform a function separate for each statement, but this is obviously inefficient. Within the select statement of the view, however, I don't know how each of the values that I need to get back.
  
  For example, right now, I have:
  
  Table 1:
  sequence_number NUMBER (10),
  name varchar (30),
  ...
  
  Table2:
  Table1_seq NUMBER (10),
  action_seq NUMBER (10),
  action_date DATE,
  action_office VARCHAR (3),
  action_value VARCHAR (60),
  ...
  
  I can't just simply join Table1 and Table2 because I have to perform processing in order to determine the rows returned matching, I really need to select. If the package opens a cursor and treats each line until it finds the one I need.
  
  The following works but is ineffective since all calls to the package returns the columns of the same record. I don't know how to put all the values that I need in the SELECT statement.
  CREATE VIEW all_this_stuff AS
  SELECT sequence_number, name,
  RP.action_date (sequence_number) action_date,
  RP.action_office (sequence_number) action_office,
  RP.action_value (sequence_number) action_value
  FROM table1
  
  Is there a way to return multiple values in my SELECT statement or I'm going about this all wrong?
  
  Any suggestions?
  
  Thank you very much!

  Hello

  What you want is a Query of Top - N , what you can do using the ROW_NUMBER analytic function in a subquery, like this:

  WITH     got_rnum     AS
  (
       SELECT     action_seq, action_dt, action_office, action_type, action_value
       ,     ROW_NUMBER () OVER ( ORDER BY  action_date
                                 ,            action_seq
                           ,            action_serial
                         ) AS rnum
       FROM     table2
       WHERE     action_code     = 'AB'
       AND     action_office     LIKE 'E'     -- Is this right?
  )
  SELECT     action_seq, action_dt, action_office, action_type, action_value
  FROM     got_rnum
  WHERE     rnum     = 1
  ;
  

  As written, this returns a single line (at most).
  I suspect you'll actually get a rank for each group , where a group is defined by a value in a table in which you join.
  In this case, add a PARTITION BY clause to the ROW_NUMBER function.
  If post you a small example of data (CREATE TABLE and INSERT statements), I could show you exactly how.
  As I don't have your tables, I'll show you the use of the tables in the scott schema.
  This is a view containing data in the scott.dept table and also to scott.emp, but only for the highest employee in each Department (in other words, the employee whose oldest hire date). If there be a tie for the first hire date, while the candidate with the lowest empno is selected.

  CREATE OR REPLACE VIEW     senior_emp
  AS
  WITH     got_rnum     AS
  (
       SELECT     d.deptno
       ,     d.dname
       ,     e.empno
       ,     e.ename
       ,     e.hiredate
       ,     ROW_NUMBER () OVER ( PARTITION BY  d.deptno
                                 ORDER BY          e.hiredate
                           ,                e.empno
                         ) AS rnum
       FROM     scott.dept     d
       JOIN     scott.emp     e     ON     d.deptno     = e.deptno
  )
  SELECT     deptno
  ,     dname
  ,     empno
  ,     ename
  ,     hiredate
  FROM     got_rnum
  WHERE     rnum     = 1
  ;
  
  SELECT     *
  FROM     senior_emp
  ;
  

  Output:

  .    DEPTNO DNAME               EMPNO ENAME      HIREDATE
  ---------- -------------- ---------- ---------- ---------
          10 ACCOUNTING           7782 CLARK      09-JUN-81

          30 SALES                7499 ALLEN      20-FEB-81
  

  Moreover, one of the conditions to the query you posted has been

  action_office     LIKE 'E'
  

  which equals

  action_office     = 'E'
  

  (AS is always equivalent to = if the string that follows AS does not contain the winning cards.)
  Did you mean say that or did you mean something like this:

  action_office     LIKE 'E%'
  

  Instead?

• Return each value only once using cfloop query

  Hello

  I have a code that fills a cfselect list dynamically and then fills a second list based on these values.

  OUT parametere v_r could contain data for one line only, so if your query

  Select * into v_r from emp

  returns multiple rows, you're bound to get "ORA-01422: exact fetch returns more than number of lines.

  You can use SYS_REFCURSOR or Collections instead.

• Multiple values per column in the stacked bar chart

  I want to use a bar chart stacked in a dashboard of the process, but I am wondering how I can add multiple values per column, because through the available methods, you can only add one value per column. I add some values to hardcode and I get the chart but, for example, I want to add series anocher in the table named 'Closed' and values for this in each column (January, February, etc.)
  
  Data source for filling
  result as a Fuego.Chart.DefaultXYDataSource
  result = Fuego.Chart.DefaultXYDataSource ("Opened");
  
  addValue result
  using
  value = 5,
  columnHeader = "January".
  
  addValue result
  using
  value = 10,
  columnHeader = "February".
  
  addValue result
  using
  value = 15,
  columnHeader = "March".
  
  addValue result
  using
  value = 7,
  columnHeader = "April".
  
  
  I enjoyed your collaboration if you have worked with graphics stacked bar.

  Hello

  You were very close.

  Try to use the Fuego.Chart.XYZDataSourceImpl object. This will give you the third dimension that your stacked bar chart needs and these attributes in the addValue method:

• value
  
• rowHeader (maybe that's where you set your month name)
  
• columnHeader (maybe it's where set it to 'Open' or 'Closed' in your example)

• Once again the model regions

  I created a template to work on our new site I'm developing and using CSS for a stronger than our current site.
  
  I have two editable regions, one of 'content', I'm having a problem with. Two optional regions called 'css' and 'w3c' that work great.
  
  When I apply the model to a page and line up the "incompatible" regions to get the text of the page based on my "content" region It works; but the content is flush with the border of the left hand rather than use my 'content' CSS rule to apply a sufficient margin so that the text is 'in' page.
  
  Incorrect page can be seen here.
  
  The only way I can get the content to sit within the content (with margins applied) by creating a page "empty" based on the model and copy the text into the "Div".
  
  Any help would be appreciated, thanks

  My rule: never apply a template to a page with the existing content.

• APEX 4.0.1: $v () function returns multiple values for the box?

  Hello
  
  I have a report that uses apex_item.checkbox (...) to generate the check box. This report correctly displays a check box for each line. The source code that is generated in the html page is:
  < input type = "checkbox" name = "f01" value = "202" id = "P1_CHECKBOX" / >
  ...
  ...
  < input type = "checkbox" name = "f01" value = "220" id = "P1_CHECKBOX" / >
  ...
  ...
  < input type = "checkbox" name = "f01" value = "210" id = "P1_CHECKBOX" / >
  ...
  ...
  
  I want to use the javascript function $v () to get the values of the enabled check box. I thought that the return of this function all the checked values separated by ':' but I noticed that my code alert ($v ('P1_CHECKBOX')); return whenever the value of the first checkbox if it is checked.
  It returns '202' if the first box is checked, but nothing, if only the second checkbox is checked and '202' if the box of the first and the second is checked.

  Hello

  first of all, $v, $x and $s are supposed to not work for items on the page, not the columns in a table or manually generated HTML elements.

  Secondly, I think that your HTML code is not correct, because each of your boxes has the same ID. But the ID must be unique in the DOM of the browser tree. Thus the different box should actually named P1_CHECKBOX_1... P1_CHECKBOX_3. Just look at what is actually generated for a page element real checkbox. BTW, I think that you should not name the checkbox as part of page elements, because they are not actually page elements. I think that this could be confusing for other developers.

  Hope that helps
