• 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)

• 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
          20 RESEARCH             7369 SMITH      17-DEC-80
          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?

• 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

  Sachin jerbi

  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 at once of the listOfValues region

  Friends,
  
  I created a (listOfValues) region that has 4 fields/columns
  
  ResponsibilityName, ResponsibilityId, ApplicationName, ApplicationId
  
  I assigned a responsibility field ResponsibilityName of the listOfValues in a page.
  
  It works fine when I select a value in this LOV. It returns a value to the field of 'Responsibility' of the page.
  
  Is it possible to return the other 3 fields so while selecting ResponsibilityName in LOV. for example while you select a value for the field 'Responsibility', can the LOV return ResponsibilityId LOV to the 'ResponsibilityId' field in the page, at the same time?
  
  1 selection can return values 1 to the fields?

  You can return multiple values in the LOV. Simply create a result to the mapping of the array element Lov to the basic element of page. Once you select a value from the LOV, the element of basic page could get filled in with the value on the table of lov whereby it has been mapped.

• Another REGEXP question: how to extract multiple values from a string

  Hi, how can I retrieve multiple values to a string with RegExp with Oracle SQL constructs?
  
  Have looked at the various examples, I cannot understand this.
  the following Sql code

  select
     regexp_substr(sessie."rollen", 'CN=A_role') "A_role"
     from ( 
  select '
  CN=A_role,OU=a_org_unit,OU=another_org_unit,DC=bz,DC=ad,DC=min,DC=local

  CN=Users,OU=Dep,DC=bz,DC=ad,DC=min,DC=local
  '   "rollen" from dual
  ) sessie;

  Returns CN = A_role.
  I want him back all of the CN = concatenated values with a semicolon and stripped of the CN = bit.
  So: A_role; Another_role; Users .
  
  Any help would be much appreciated. Here I use database 11g 11.2.0.2.0.
  
  Does anyone have an idea how to do this in SQL?

  How to configure contextual events publish several values of payload?
  
  On click of a button, I'm declaritively publish a contextual event, which works very well when a single value is passed to the event handler.
  
  My event handler method has the signature of:
  eventHandler (String)
  
  But now I also have an oracle.jbo.domain.Number, so my new eventHandler looks like this:
  eventHandler (Number, String)
  
  How to pass two values during editing of the event and how to place the payload with multiple values for the new eventHandler?
  
  All article or code would be greatly appreciated.
  
  Thanks for the help.

• How to return the value 0 for no data using the County?

  Hi all
  I used this query to count the number of records for each month of the year:
  
  SELECT DISTINCT COUNT (I.information_sid) COUNT, TO_DATE (TO_CHAR (INSERT_DATE, 'MM'), 'MM') MONTH
  
  INFORMATION I
  
  TO_DATE GROUP (TO_CHAR (INSERT_DATE, 'MM'), 'MM')
  
  ORDER BY TO_DATE (TO_CHAR (INSERT_DATE, 'MM'), 'MM')
  
  But this code returns no value for months without data
  I want to return the value '0' for any month of data. How, please?
  
  Note: I use reports 6i.

  Maybe this?

  SELECT SUM(CNT_REC) CNT_REC, MONTH
  FROM
  (
  SELECT COUNT(I.information_sid) CNT_REC, TO_DATE(TO_CHAR(INSERT_DATE,'MM'),'MM') MONTH
  FROM INFORMATIONS I
  GROUP BY TO_DATE(TO_CHAR(INSERT_DATE,'MM'),'MM')
  UNION ALL
  SELECT 0, LPAD(ROWNUM,2,0)
  FROM ALL_OBJECTS
  WHERE ROWNUM <= 12
  )
  GROUP BY MONTH
  ORDER BY MONTH
  

  No need to SEPARATE during the use of GROUP BY.

• How to pass multiple values to a data model parameter

  I have a data model, where I put a setting like this.
  
  Select col1, col2, col3 from table1 where col1 =: param1
  
  This works very well for a single value that I pass the param1 parameter.
  
  How can I get this to work when I want to send multiple values for param1. I already checked the box "Multiple values" and tried to change the sql for this code.
  
  Select col1, col2, col3 from table1 where col1 in: param1
  
  Looks like I'm missing something here.
  
  
  
  Thanks in advance!

  you need to write it as:

  Select col1, col2, col3 from table1 where col1 in (: param1)

  It works for me.

• How to return two values of a function?

  Hi all
  I have a function which returns a varchar2 value. This value is used in the SQL of a ref cursor
  
  Now I want this function returns two values. I tried to use varray, but could not accomplish the task.
  
  Can you tell me how can I find the two values from a function? and how this function can be called in a SQL query?
  
  Thank you very much

  The query should look like:

  SELECT v.col.name AS name
       , v.col.flag AS flag
  FROM   ( SELECT kk_test_kk(t.somecolumn,t.someothercolumn,42) AS col
           FROM   sometable t ) v;
  

  Note that you need to prefix with the name of view inline ('v' in the example) and the expression of the function ('col' in the example).
