How to return multiple variables from a function

• 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?

• 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

• 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).

  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.

• How to access a variable from a mxml mxml in another?

  I have Vbox with Hbox turn hbox has some components... TextInput...

  I m adding that Vbox in another mxml... by iteration file...

  I need the sum of all the input values in the text boxes to display in the text box in another Mxml...

  I take the sum in a variable and you want to show tha some in another file...

  How can I get this variable in my resulting mxml?

  TIA

  If you have another component in MXML it compiles to be a class. You can create a public function to sum the values in the component - allows you to call valueTotals(). If in your application, the mxml component has an id of "MyComponent" then you can access the totals as myComponent.valueTotals ().

  It is a way to do it, but maybe this isn't the best way. It's certainly better than the access to all the individual values in MyComponent.

• How to create multiple hierarchies from the same physical table

  Hi all
  
  I have a physical table to join with a fact table: there are 3 different hierarchies, which share the last 2 levels inside the dimension table. It's the logic diagram of hierarchies:
  
  Dimension services
  -Business
  -Sector
  -Type
  -Operator
  -Product
  Partner of dimension
  -Partner
  -Operator
  -Product
  Contractor of dimension
  -Contractor
  -Operator
  -Product
  
  All columns are in the same table physical source. I tried to create 3 table logic source from the same physical table, everyone with all the columns and create a hierarchy for each dimension table, but it gives me nQSError: 15011.
  
  Any suggestion? Maybe the physical table alias can help for the creation of tables of different sizes?
  
  Thanks in advance,
  Concerning

  Hello

  It is a basic rule that you cannot create multiple hierarchies in a single dimension table, so what you do is create three tables of alias and slip into MDB layer in 3 different sizes and on top these tables create 3 different dimension hierarchies.

  Check if useful/correct

  Thank you.

• How to download multiple files from creative cloud

  I downloaded about 30 photos of creative cloud storage. Now, I can't find a way to download a group or all at the same time. You can select multiple and move to different folders within CC, but can not download multiple. I had known this before using it, I would have done a zip of images folder. It seems a bit awkward, if this is true.

  [email protected]

  Thanks for the info. As a professional user, more features in storage would be useful. At the moment I am using to other file storage and transfer solutions that are far superior.

  I think most of the users of cloud would very well agree with you.

  The cloud is now a reasonable version 1, but it is clumsy, he lacks the basic features and is a latecomer to a mature market quickly. Other offers currently shine in comparison.

  Our expectations as consumers are very high, because we are accustomed to the are (and other superior 3 third-party solutions) there.

  Adobe has been flooded with suggestions of features and improvements from users. The more, the better.

  They could, as they claim, work on improvements, but they move on until the cloud tarnishing its own reputation too due to the lack of (expected) features.

• How to return multiple images using the batch command

  With the help of Fireworks 8.
  
  I have a document with more than 200 executives. In the "Command"-> "Batch commands" menu I have the possibility of rotation and or multiple or individual images blur.
  
  What I would really like to do is to return all 200 images horizontally, but there is no option to do this at the same time.
  
  Or is it?
  
  Tell me that I'm not stuck with the only option of failover each picture individually.
  
  I have knocked down an image and recorded my actions as a command, but this "Flip" command could not be applied to several frames.
  
  Help out me.
  
  Thanx.

  You will need to use the feature to peel the onion of the Panel frames, as
  Alex said.

  Go to the control panel frames. Assign to all managers of onion (the box on the)
  left side of each image - click on the Executive in the area of skin of onion,
  Then click on the lower frame. You will see a line connecting all the
  frames) then click and drag on your entire canvas area to select all
  executives. If you have saved the command, you will find at the bottom of
  the menu of commands.

  This does not work, I just did.

• How to use global variables from a dll in another (not multi-threaded)

  With LabWindows/CVI. I try to be compatible with legacy code, so this isn't the best way to do things, but it saves me some headaches.

  I have a project/.dll called "GlobalBlock" that contains some parameters used widely throughout the program. The entire program consists of several DLLs, for the purpose of encapsulation.

  GlobalBlock.c contains:

  menu_sdef G_setprefs = struct
  {
  ... stuff

  };

  sys_fileheader_sdef Level1Version = struct
  {
  ... more

  };

  struct G_sys_flags sys_flags_sdef;

  In the dll that owns the variable, use the _export on this qualifier. This will ensure that it is placed in the list of the interface dll. In the application (dll or other) that wants to make reference to that variable, use the qualifier _import on it. This tells the system to use the associated import library that comes with the dll in order to resolve references running.
