• How to use the user defined function in the Update statement

  Hi all
  
  I wrote under the update statement to update the column based on the return value of function. but it does not work. Could someone help me on this. This function returns a single value for each project.
  
  Thanks in advance.

  Thank you

  PLS-00231: function 'MONTHS_IN_STAGE_CNT_RET' cannot be used in SQL

  -What is the function that is declared private in a package? If Yes, then it must be public, otherwise the SQL engine cannot be used.

• the user-defined function

  Hi, experts,
  I wrote a sql query to get the amount after calculation.
  
  

  SELECT A.FORM_NO, C.SKUCODE, B.QUANTITY * (
  CASE WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) = 2008 AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) = 2008 THEN 
  TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) - TO_NUMBER(TO_CHAR(A.START_DATE,'MM'))  +1 
  WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) = 2008 AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) > 2008 THEN
  12- TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) + 1
  WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) < 2008 AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) = 2008 THEN 
  TO_NUMBER(TO_CHAR(A.END_DATE,'MM'))
  WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) < 2008 AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) > 2008 THEN
  12 ELSE 0 END )/((TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) - TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY'))) *12 + TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) - TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) + 1 )
  
  AS QUAN
  FROM FORM_TBL A, QUANTITY_TBL B, SKU_TBL C
  WHERE A.FORMNO = B.FORMNO AND B.SKU = C.SKU;

  It runs correctly, and no error returned.
  
  
  I would change for a user-defined function.
  
  

  create or replace
  function get_quantity
          (pi_year number, pi_year_diff number, pi_form_no varchar2, pi_skucode varchar2)
          return number is
      po_quantity number;
  begin
      
      
      SELECT ( B.QUANTITY * (
      CASE WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) = (pi_year + pi_year_diff) AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) = (pi_year + pi_year_diff) THEN 
      TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) - TO_NUMBER(TO_CHAR(A.START_DATE,'MM'))  +1 
      WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) = (pi_year + pi_year_diff) AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) > (pi_year + pi_year_diff) THEN
      12- TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) + 1
      WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) < (pi_year + pi_year_diff) AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) = (pi_year + pi_year_diff) THEN 
      TO_NUMBER(TO_CHAR(A.END_DATE,'MM'))
      WHEN TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY')) < (pi_year + pi_year_diff) AND TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) > (pi_year + pi_year_diff) THEN
      12 ELSE 0 END )/((TO_NUMBER(TO_CHAR(A.END_DATE,'YYYY')) - TO_NUMBER(TO_CHAR(A.START_DATE,'YYYY'))) *12 + TO_NUMBER(TO_CHAR(A.END_DATE,'MM')) - TO_NUMBER(TO_CHAR(A.START_DATE,'MM')) + 1 ))
      
      into po_quantity
      FROM FORM_TBL A, QUANTITY_TBL B, SKU_TBL C
      WHERE A.FORMNO = B.FORMNO AND B.SKU = C.SKU
      and c.skucode = pi_skucode and a.form_no = pi_form_no;
  return po_quantity;
  end;

• The user-defined functions...

  Hi all
  
  Where do we store the functions defined by the user of CF (models) in order so that it can be called by any model of CF? In the Custom Tag folder? In the directory root CF?
  
  
  Thanks in advance!

  We re-use our functions across different sites (I think it's what your bet to) using the method 'BlackBox '. I'm sure there are other ways, but this is the norm for society, that I work. For more information, see
  http://www.cfblackbox.com/

  Additional information:
  You can store them anywhere in your site, but you can declare the function once. For example, if you have a page that includes two models. Each of the two models to compose the same model that holds your function. This will cause an error. In addition, if you have the model in a loop, it will cause an error.

• Problem with the implementation of a user-defined function

  Hello.
  I wonder if you could help create a user function in ODI, which would do exactly the same thing as this one:
  
  create or replace function Konwersja (psWejscie VARCHAR2) return DATE is
  dDate DATE;
  Start
  dDate: = TO_DATE (psWejscie, ' DD month yyyy ',' NLS_DATE_LANGUAGE = POLISH ');
  RETURN dDate;
  EXCEPTION
  WHILE OTHERS THEN
  RETURNS A NULL VALUE.
  END;
  
  I tried to put Konwersja (psWejscie VARCHAR2) and Konwersja ($(psWejscie)) in the syntax and the rest in the implementation in Oracle syntax, but when I used it in an interface to load data to a date column (Konwersja (.)) (("" Data_U ")), I got an ORA-00923 exception

  Yes, you can call this function from the DB interface directly. In the interface mapping column say Konwersja () it will work.

• A query can be passed to the user-defined function?

  Hello
  I created a function that takes one parameter and returns a value. Now tha value that is passed into the function comes also from a query, so can I pass that Charly directly in the parameter?
  I tried this but it is giving error: ORA-00936: lack of expression.
  

  select ID from table1
  where areaid=f_getAreaID(SELECT sec FROM table2 WHERE artid='3232') and 
  type='p002' 

  Above code is in error. How do I get my requirement?
  Note: Assume that query to the function will always return a value of skis.
  
  Published by: bootstrap on August 28, 2011 12:13

  Subquery must be enclosed in parentheses. Function parameters must be placed in brackets. Therefore, you should use

  select ID from table1
  where areaid=f_getAreaID((SELECT sec FROM table2 WHERE artid='3232')) and
  type='p002'
  

  Remember, it must be a scalar subquery (subquery returns one or no line).

• User-defined function removes the expression hooks

  Trying to convert this column in a user function expression, however when I apply the function to the user hooks literally disappear.

  1 REGEXP_REPLACE (SRC_IO_PHONES_A.PHONE, ' ({: digit:{3})\.(:digit:{3})\.(:digit:{4})' 1 (\1)-\2-\3'),)

  2 REGEXP_REPLACE (SRC_IO_PHONES_A.PHONE, ' ([[: digit:]] {3})------.) () [[: digit:]] {3}). ([[: digit:]] {4})' 1 (\1)-\2-\3')

  
  

  These lines come from the same mapping. One implements the user-defined function and the second line is with I plug the code into the target Expression field.

  
  

  Any thoughts on why this is?

  
  

  Thank you
  

  So I thought to it thanks to a post of @oraclebase.  Another friend of mine has indicated that user in ODI functions develops a sort of pseudo-code and it is not really passing commands to the database.  Anyway, my research turned to substitute for the construction of all [: digit:].  This resulted in me find the above post where \d = [0-9].  By replacing all the scoring by \d hooks, the function worked.

• How to use the user with event loop event

  Hello

  I want to communicate between 2 VI, so I have a global variable (boolean) who gives the order to an event tool to run. The problem comes from the fact that event loop accepts no global variable, I found on the forum that I can use the user event. Of course, the second VI works normally when I push the button (boolean) in there to run the event loop. Please can someone explain me how to do this, I am a chemist.

  Thank you.

  You enter the receiver structure of event for the event you want to receive.

  

  To do this in two screws, you will have to share the user between them event reference.

  GROUP BY will manage the SUM function, but the MIN is used incorrectly - use another SELECTION to get it, or work with only with a single line. Otherwise, you could do WITH... get the SUM of SELECT MIN...
