• Help on parameters public static function

  Hello

  I have two functions in the same file, how can I use the first function as a default value in the second function.

  public static function get decimalFormatter1 (): {NumberFormatter

  //

  }

  I have try this:

  public static void secondFunction(param1:String,_param2:Int=0,_ _param3:Function=decimalFormatter1_):Array {}

  //

  }

  Error:-1047: unknown parameter initializer or isn't a compilation constant.

  Any ideas?

  Thank you!

  To work around the problem, you can use null as default, where null means "use the decimalFormatter1. You have to write something like

  public static void secondFunction(param1:String,_param2:int_=_0,_param3:Function_=_null):Array
  {

  trainer: function var = null;

  If (param3 is nothing)

  Formatter = decimalFormatter1;

  ....

  }

  all instances of the object, as all the rows in the table

  I think you misuderstand objects. Objects do not come from thin air - it must exist somewhere or should be constructed from the data. Your function constructs the table utem data object. If you have any item in the table, which should be used?

• Help with packages and functions that it

  Hello, I need help with the package.
  I have two tables of the employee base (id, firstname, lastname, etc..) T1 and T2.
  What I need, it's a package and two features inside. First function reads the data from T1 and passes to the second function, where second function reads data from T2 and concatenates the data just read with data from function1 and data T1 + T2 function2 goes on the main program that displays this data.
  
  So far, I have:

  create or replace type emp_type as object
  (id number,
  firstname varchar(20),
  lastname varchar(20),
  salary number(9,2));
  
  create or replace type emp_type_table as table of emp_type;
  
  create or replace package my_package
  is emp_table emp_type_table:= emp_type_table();      -- *not sure if this line is correct*
  function get_T1_emp return emp_type_table;
  function get_T2_emp (T1_emp in emp_type_table) return emp_type_table;
  end my_package;
  
  -- *confusion begins*
  
  create or replace package body my_package as 
  function get_T1_emp
  return  emp_type_table as 
    emp_table emp_type_table:= emp_type_table();
  begin
       for i in (select * from T1) loop
           emp_table.extend;
           emp_table(emp_table.count):= (emp_type(i.id, i.firstname, i.lastname, i.salary));
        end loop;
      return emp_table; 
  end get_T1_emp; 

  - get_T1_emp function seems to be quite beautiful. At least it works separately
  

  function get_T2_emp (T1_emp in emp_type_table)
  return  emp_type_table  
    emp_table emp_type_table:= emp_type_table();
  begin
       for i in (select * from T2) loop
           T1_emp.extend;
           T1_emp(T1_emp.count):= (emp_type(i.id, i.firstname, i.lastname, i.salary));
        end loop;
      return T1_emp; 
  end get_T2_emp;
  end my_package;
  
  
  DECLARE
    v_Return emp_type_table;
    v_Return2 emp_type_table;
  BEGIN
    v_Return := get_T1_emp;
    v_Return2 := get_T2_emp(v_Return);
    for i in 1..2 loop
      DBMS_OUTPUT.PUT_LINE(v_Return2(i).id || ', ' || v_Return2(i).firstname || ', ' || v_Return2(i).lastname 
      || ', ' || v_Return2(i).salary || 'EUR');
    end loop;
  END;

  So basically I don't know about my tax package.
  Most important, I don't know how to write the get_T2_emp function. And also not very sure of my main function. Please can someone help my with my problem

• Help with JDBC stored functions

  Hello.. Im having problems with my stored functions (java oracle), where I create the functions but then im I call them, it does not return any value (nothing happens after that I called my function). Can someone help me?
  
  Here's how to create the registered function:
  
  /************************************************** ****************/
  create or replace FUNCTION insert_client_func (a_client_name IN CLIENTS.client_name%TYPE)
  
  RETURN VARCHAR2
  
  IS
  
  
  BEGIN
  
  INSERT INTO CUSTOMERS (client_name)
  
  VALUES (a_client_name);
  
  
  Return a_client_name;
  
  END;
  /************************************************** *****************/
  
  Heres how I call it:
  
  /************************************************** *****************/
  name = "'" + name + "'";
  
  Command string = "{call insert_client_func("+name+")}";
  
  try {}
  String url="jdbcracle:thin:@localhost:1521e; »
  this.dbConnection = DriverManager.getConnection (url, "bd2009", "bd2009");
  System.out.println (Command);
  This.callstmt = This.DbConnection.prepareCall (command d);
  this.callstmt.registerOutParameter (1, Types.VARCHAR);
  this.callstmt.executeUpdate ();
  String simpleArray = this.callstmt.getString (1);
  System.out.println (simpleArray);
  
  this.dbConnection.commit ();
  This.callstmt.Close ();
  this.dbConnection.close ();
  }
  /************************************************** *****************/

  The syntax of your call is incorrect. For functions, it should be

  "{ ? = call insert_client_func (?)} »

  You can also use the syntax of PL/SQL

  ' BEGIN?: = insert_client_func (a_client_name =>?); END; »

  Then configure your settings

  this.callstmt.registerOutParameter (1, Types.VARCHAR);
  this.callstmt.setObject(2, );

  What is the data type of IN_CLIENTS.client_name?

  Call the function and retrieve the return value

  This.callstmt.Execute ();
  String value = this.callstmt.getString (1);

• I need a little help with the INSTR function

  Hello everyone,
  
  im still new to pl sql and experienced an issue with the INSTR function. I need to analyze some values of a CLOB containing the xml code and use INSTR to determine the beginning and end of the value, I would like to analyze.
  
  the data I need is in a <!-[CDATA [[Some Text]]]-> block. up to this point, I managed to take the start of the word, but I can't seem to capture the end of the CDATA block. I use this statement:
  
  POS: = INSTR (TO_CHAR (input_clob) [,'] ', pos2 + 6, 1);
  
  but it doesn't have the desired effect. [It seems to sort of go back to the length of the string, while the]-sign is actually in the xml file. my result would look to "Some Text]]--> < xmlxml >... < / xmlxml >...» ». [I tried to escape by writing ' \] "but if I do, the function returns zero and my parsed string is left blank.
  
  Unfortunately I can't use regular expressions, because I work with oracle 9.2i. Anyone know what I'm doing wrong?
  
  Thank you

  Hello
  You need a subquery, but you don't need more than that.
  Here's a way to eliminate the additional subquery:
  WITH     got_analytics     AS
  (
       SELECT  emp_id,     mgr_id,     emp_name, dpt_nme, salary
       ,     ROW_NUMBER () OVER ( PARTITION BY  dpt_nme
                                 ORDER BY          salary     DESC
                         )         AS rn
       ,     COUNT (*)     OVER ( PARTITION BY  dpt_nme
                                     )         AS dpt_cnt
       FROM     t
  )
  SELECT  emp_id,     mgr_id,     emp_name, dpt_nme, salary
  ,     rn
  FROM     got_analytics
  WHERE     rn     < 3
  AND     dpt_cnt     > 1
  ;
  
  Analytical functions are calculated after the clause WHERE is applied. Since we need to use the results of the analytical ROW_NUMBER function in a WHERE clause, which means that we have to calculate ROW_NUMBER in a subquery and use the results in the WHERE clause of the main query. We can call the COUNT function analytical in the same auxiliary request and use the results in the same WHERE clause of the main query.
  Would what results you if there is a link for the 2nd highest salary in some Department? For example, if you add this line to your sample data:
  select 7 ,3 ,'Sunil',8000,12000,'IT' from dual  union
  
  ? You can use RANK rather than ROW_NUMBER.
  		   

• Help with some date functions.

  I need to write code that allows a person to, at the beginning of the year, to cancel all records that relate to the previous year.
  For example, on 05/01/11, all records for the year 2010 should be cancelled by inserting the cancellation_date as the last date of this same year.
  
  So I thought that the best way to proceed would be with this function:
  CREATE OR REPLACE FUNCTION TEST2
  DATE OF RETURN
  AS
  
  v_prior_year tank (4);
  v_last_second_string VARCHAR2 (20);
  v_last_second_date DATE;
  
  BEGIN
  
  -The year of the SYSDATE extract, convert it to a number, subtract 1, convert that year to a string.
  v_prior_year: = TO_CHAR (TO_NUMBER (TO_CHAR (SYSDATE, 'YYYY'))-1);
  
  -Build a string that consists of the last second of the same year.
  "v_last_second_string: = ' 31 - DEC - ' | v_prior_year | "235959 ';
  
  -Convert the string to a date.
  v_last_second_date: = TO_DATE (v_last_second_string, ' ' MY - DD - YYYY HH24MISS);
  
  RETURN v_last_second_date;
  
  END Test2;
  
  I was wondering if there is a shorter way to do this?
  Thank you.

• Help with a case function

  Hello

  I want to create a function box where column2 is based on the value of Column1.

  For example, the table below

  On the underside, I would ask something like

  Select status, description, l3_days, (case when status = 'Open' and DEV_DAYS = null THEN L3_DAYS = 'LOGIN_DATE-SYSDATE' WHAT status = 'open' and DEV_DAYS! = NULL THEN DEV_DAYS = L3_DAYS ELSE LOGIN_DATE-L3_DAYS-SYSDATE, DEV_DAYS END)

  

  Not sure so clearly. Basically, I want to L3_DAYS and DEV_DAYS to be updated automatically based on the login_date. I plan to add a DEV_START_DATE column, which would facilitate the calculation of DEV_DAYS

  In any case I want to know how to write a case function, where denotes Column1 Column2?

  Thank you

  There are two CASE statements like this

  select status
       , description
       , case when status = 'Open' and dev_days is null then LOGIN_DATE-SYSDATE
              else l3_days
         end l3_days
       , case when status = 'Open' and dev_days is not null then LOGIN_DATE-L3_DAYS-SYSDATE
              else dev_days
         end dev_days
  

  If this isn't what you are looking for you need to explain your best condition. Provide a CREATE TABLE script and INSERT a TABLE for examples of data and provide a few example expected output.

• Need help with rewrite PLSQL function EVALUATE

  Hi all
  
  I'm trying to convert some PLSQL (from Discoverer) in a column of answers and I can't seem to get the correct formula.
  
  The original formula:
  MIN (Processed_Date) MORE (SCORE OF Business_Area, product, Serial_No)
  
  I guess that this must be done in an evaluation function, but I can't work on the correct syntax.
  
  This formula:
  Evaluate ('MIN (%1) OVER (PARTITION OF 2%, 3%, 4%)) ", Business_Area, Processed_Date, Serial_No, product)
  Has generated this error:
  [nQSError: 10058] A general error occurred. [nQSError: 22027] Union of incompatible types. (HY000)
  
  I do not know what causes the error, and tried casting explicitly throughout the column, but still getting errors.
  
  
  I am open to any suggestion.
  
  Thank you.

  Jasonr,

  highlighted in bold is the change
  Try this EVALUATE ('MIN (%1) OVER (PARTITION OF 2%, 3%, 4%)) AS the DATE, Processed_Date, Business_Area, product, Serial_No)
  update if it solved your problem.
