• Use of user defined function in mathscript containing a structure

  Hi, I am a novice user of LabView MathScript module,

  I just noticed that these files appear to be copyrighted. My first question is do you have author permissions to post them in a public forum? If this isn't the case, then you can remove them. That being said, I have reviewed the code and it seems easy enough to work around your problems (provided that you have the copyright permissions). How to bypass the problems is to replace the fields of the struct with variables. There is of course allows you to change some definitions of functions for input and output the necessary variables which I think was the best 5 variables. You will also need to redo the code that uses a table of error checking cell. In total, I estimated about 30 minutes of work. I would have given you work around these files had not been protected by copyright. So, unfortunately, you will need to implement the work around you.

• Variable with a value. «PURGE error: bad Argument Type.»

  Hi, my 50G calculator accuses a value for the variable 'X' but I can't find it in any directory, and when I try to delete I get the message "' PURGE error: bad Argument Type." " I also have the theta variable with the same problem. How can I remove the value of these variables? TKS

  In addition to Make suggestions, two other possibilities come to mind: 'X' can be a directory object (which would cause the error to the wrong Type of Argument because non-empty directory objects cannot be purged by PURGE, but must be purged by PGDIR), or it could be a local variable (which can only be served by putting an end to the environment that created which is usually a program).  So if Make suggestions don't work, try foster 'X' PGDIR and if that does not work, try KILL (which ends all the current environments).

  If those WHO do not work, please do 'X' TYPE HOME and tell us what object type 'X'.

  None of the answers was * exactly * correct, but they gave me enough information to solve the problem.

  To implement what I have to code the functions a bit differently.

  • BPEL functions are all the IXpathFunction extension classes.
  • Mapper functions are not.
  • BPEL functions are each separate classes.
  • A single class with a method for each desired function mapper functions.
  • BPEL classes outcrop in the config file ext-bpel-xpath-functions-config. XML
  • The Mapper class is exposed in the config file ext-Mapper-xpath-functions - config.xml

  A BPEL class looks like:

  public class editCaseNumber implements IXPathFunction {
      public Object call(IXPathContext context, List args) throws XPathFunctionException {
         return docOut;
      }
  }
  

  A class to map looks like:

  public class mapperFunctions {
      public static String replaceString(String sIn,String sMat,String sRep,String mode){
          return finalString;
      }
      public static XMLDocumentFragment compressFile(String indoc){
          return docOut;
      }
  }
  

  (I deleted the code of these to avoid confusion.)

• How to create a user-defined function?

  is there a substitute for the exe instsrv and srvany in Vista?

  I don't know what means your post, so here's how to create a user-defined function:
  1) click Start
  (2) select "Control Panel".
  (3) select "system and maintenance".
  4) click on "Administrative Tools".
  5) click on "Task Scheduler."
  (6) click on "create task" (right in the list pane under) "Actions") "
  "(7) opened in the general tab it will choose if it only works when the account that is used to implement is connected, or ' if that user is logged in or not" (leave the box ' do not store the... "empty password)
  (8) always in the general tab, check the box 'run with highest privileges '. (This will ensure that no program can block)
  (9) type a name for the task (in the general tab)
  (10) to set the job to run an awhile, use the "triggers" tab, if you want to set a task runs after xx min. temps_inactivite, choose the 'conditions' tab, then choose the desired time.
  (12) click on the 'actions' tab click on 'new '. in the program/script line, search for and select the program you want to run, and then click Open.

• any user defined function in the rule set by the user

  Hello

  I wonder if I can use a function defined by the user in a rule set by the user in oracle sem... I've seen examples of user defined function the used in sparql query filter clause in this guide to dev... However, I don't know if I can define a function in oracle database SEM. and use it in the body rule or the head. For example, I want to define a function of the length that allow to calculate the difference between two dates.  So, I want to set a rule as follows: event1: d1 and event1 has_start_date: has_end_date d2 and duration (24, d1, d2) then event1:date_satisfiable 'yes '. Oracle supports this type of rule? Thank you very much.

  I just tried and it works.

  I also added

  System.out.Print (MBound);

  just before the return (MBound);

  in the Java class

  I created a calc script against Sample.Basic

  Fix("Florida","100-10","Actual","Apr")

  ('Sales'
  'Sales' = @Amort (0.06, 360, 10000000);
  )

  ENDFIX

  I run essbase in the foreground, so I see the exit of System.out.print (Mbound);
  Validated the script "59955.05251799688" was written in the output window, so the Java class works.
  I also ran the calc script and the value was written in 'Sales' (the block already existed for the POV before anyone says that my script would not work)

  I registered the CDF of Java with.
  create or replace function '@AMORT' as
  "Amortization.Amort (double, int, double).

  You must ensure that you see something like the following in the application log or output in the command window.

  External function of [GLOBAL] [@AMORT] saved OK

• Help! User-defined function problem.

  Need help on using custom function defined in Essbase. Thanks in advance!
  
  I have not found a function of depreciation in Essbase, so thought I might create one in Java and save it as a user defined function. However, I can't get this to work.
  
  Here's what I did:
  1. I created a java class called depreciation.
  
  public class {depreciation
  
  public double Adeath (double r, int period, double LoanBalance) {}
  Double LBound = LoanBalance/period;
  Double UBound = LoanBalance;
  Double MBound =(LBound+UBound)/2;
  Double err = 0;
  int i = 0;
  
  Calculate amortization payment
  {}
  Double MBalance is PVCalc (r, Period, MBound);.
  ERR = MBalance-LoanBalance;
  If (err > 0) {}
  UBound = MBound ;}
  If (err < = 0) {}
  LBound = MBound ;}
  MBound =(UBound+LBound)/2;
  i ++ ;
  }
  While (err > 0.001 | err <-0,001 & & I < = 100);
  
  return (MBound);
  }
  
  
  define the present value
  public static double PVCalc (double rate, NPER, double PMT int) {}
  Double pvpmt = pmt;
  Double cpvpmt = 0;
  
  for (int j = NPM; j > 0; j-) {}
  for (int i = 1; i < = j; i ++) {}
  pvpmt = pvpmt /(1+rate/12);
  }
  cpvpmt = cpvpmt + pvpmt;
  pvpmt = pmt;
  }
  Return cpvpmt;
  }
  }
  
  2. copy the .jar to 'C:\Hyperion\AnalysticServices\java\udf '.
  3. has created a new MaxL file and run the script that runs:
  
  create or replace function '@Amortize' as
  'Amortization.Amort '.
  Spec "@Amortize (spleen, period, balance)"
  
  It shows: statement executed successfully.
  
  4 then I tried to test in the following statement:
  
  If (@isuda ("Time", "Test Date"))
  "Depreciation Payment"=@Amortize (0.06, 360, 10000000);
  endif;
  
  And I got an error message as below:
  Error compiling formula [amortization payment] (line 2): [)] without [()]
  
  Could someone help me with this issue? 1 million thanks!

  The udf.policy file is located in the hyperion\products\essbase\essbaseserver\java directory and put the security on the java interface with Essbase points if there is a dev environment you can open the file with Notepad and go to the bottom of it. You will find a line
  permission java.security.AllPermission;

  remove the / / (which comments out) and this will allow all java functions are allowed. After the change, you must restart the service Essbase

• 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.

• User defined function join VS - Performance...

  Hi all
  
  all connecting mulitple table and get values... which one is the best?
  Join or user-defined function...
  
  
  row function
  --------------------------
  
  
  Select b.SID, get_salary (empid) from emp;
  
  Note: get_salary function will return the salary of the pay tables.
  
  Using joins
  --------------
  
  
  Select b.SID, b.salary from emp, a, b of salary
  where a.empid = b.empid;
  
  
  What is the best performancewise?
  
  also if you give any related document also very well.
  
  Thanks in advance.

  Always try to avoid calling a function defined by the user from a SQL statement.
  Word: context switching.

• User-Defined Functions

  Hi, I am a newbie in oracle database,
  
  I want to know if this is possible:
  
  is it possible to build a sql (in string format), then run it inside a function defined by the user (NOT stored procedure)?
  
  If so, are all versions of oracle database able to do this?
  
  and it's samples?
  
  and a stored procedure can be called inside a user-defined function?
  
  Thank you!

  Yes.
  Create a string that is a SQL command and then running it is called dynamic SQL .
  You can do inside of a function, or a procedure. (Attention this: all procedures and functions is often called Stored Procedures .)
  Everything you can do in a procedure, you can also do this in a function.

  If so, are all versions of oracle database able to do this?

  Yes, all versions of Oracle behave this way.

  and it's samples?

  The [PL/SQL manual | http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28370/dynamic.htm#sthref852] has many examples.
  There are a lot of questions on this forum about PL/SQL. Enter "Dynamic SQL" in the serach box (top right of the Thread list page) to see [examples | http://forums.oracle.com/forums/search.jspa?objID=f75&q=dynnamic+SQL].

  and a stored procedure can be called inside a user-defined function?

  Yes, it is done very often.

• Writing user defined function the same way as the oracle functions

  Hi guys,.
  
  In one of the interviews, I saw the guy asked me to write a function defined by the user who will be the column name and the list of all values.
  
  For example
  
  Name: employees table
  Column name: Employee_Name
  
  Employee_name
  Scott
  Ivgun
  Jack
  Shane
  
  The query must be in this marker
  
  SELECT col_agg (Employee_name) emp_name of employees;
  
  The output must be
  
  Emp_names
  Scott, ivgun, jack, shane
  
  Please let me know if this is possible
  
  
  Any suggestions will be much appreciated.
  
  Thank you
  Ranjan

  You certainly could write what a user defined aggregate function if you wish...

  for example this function will consolidate channels in a CLOB...

  create or replace type clobagg_type as object
    (
    text clob,
    static function ODCIAggregateInitialize(sctx in out clobagg_type) return number,
    member function ODCIAggregateIterate(self in out clobagg_type, value in clob) return number,
    member function ODCIAggregateTerminate(self in clobagg_type, returnvalue out clob, flags in number) return number,
    member function ODCIAggregateMerge(self in out clobagg_type, ctx2 in clobagg_type) return number
    );
  /
  create or replace type body clobagg_type is
    static function ODCIAggregateInitialize(sctx in out clobagg_type) return number is
    begin
      sctx := clobagg_type(null) ;
      return ODCIConst.Success ;
    end;
    member function ODCIAggregateIterate(self in out clobagg_type, value in clob) return number is
    begin
      self.text := self.text || value ;
      return ODCIConst.Success;
    end;
    member function ODCIAggregateTerminate(self in clobagg_type, returnvalue out clob, flags in number) return number is
    begin
      returnValue := self.text;
      return ODCIConst.Success;
    end;
    member function ODCIAggregateMerge(self in out clobagg_type, ctx2 in clobagg_type) return number is
    begin
      self.text := self.text || ctx2.text;
      return ODCIConst.Success;
    end;
  end;
  /
  create or replace function clobagg(input clob) return clob
    deterministic
    parallel_enable
    aggregate using clobagg_type;
  / 
  
  SQL> select trim(',' from clobagg(ename||',')) as enames from emp;

  OK, it's more that a function it uses a type of object that connects in operation internal to the ODCI... but it does what you ask. :)

• Why I'm not able to associate the user defined exception with ORA-01403 error code

  why I am not able to

  Associate a user defed exception with ORA-01403 error code?

  declare
   myException Exception;
   pragma exception_init(myException ,-1403);
  
   begin
   raise myException ;
  Exception
  when myException  then
   dbms_output.put_line('raised due to myException ');
   end;
  /
  

  exception of ABC;

  *

  ERROR on line 2:

  ORA-06550: line 2, column 4:

  PLS-00701: ORACLE error-1403 of PRAGMA EXCEPTION_INIT illegal number

  ORA-1403 is an outgoing BOF NO_DATA_FOUND exception. And we used to NO_DATA_FOUND in pragma exception_init + 100.

  Thus, instead of the you can used this different exception code which is not associated with any exception.

  For example:

  declare

  Exception myException;

  pragma exception_init (myException,-7856);

  Start

  raise myException;

  Exception

  When myException then

  dbms_output.put_line ('high due myException');

  end;
