• Made Oracle 6i LOV with ref cursor returned by a function of database

  Hi all

  I want to dynamically create a LOV in oracle forms 6i using the value of ref cursor returned by the function of database.

  is this possible?

  Using loop, I could able to display the values returned by the ref cursor, but how can I assign these values in the LOV?

  You will need to loop through your REF Cursor and assign each value to a group of registration of forms and then assign the Group Record to your LOV.  Take a look at the built-ins CREATE_GROUP, ADD_GROUP_COLUMN and ADD_GROUP_ROW in the help system of forms for more information about how to use these built-ins and examples of how to use them.

• Pipelined table vs ref cursor in a function return

  Hi gurus,
  
  Everybody has discovered that a (subject) is faster on the other? Data will be primarily consumed from an external application (.net). What are the benefits? I can't decide if that use is
  
  Thank you very much.

  Thank you very much.

  They are two different things.

  A pipeline table acts as an array, but you must always choose in it and so if your consumption that in .net, you would still use a Ref Cursor I guess to query this table in pipeline (I guess .net is not query the tables directly, but must use some sort of slider Ref?)

  Tables in pipeline can be fast, but it depends on what you need to. Is there a reason why you really need a feature in pipeline? If this is not the case, just use a normal query with a Ref Cursor, so your .net application only retrieves the data properly.

• Can a function returns a cursor?

  Hello
  can a function returns a cursor, or it may just return simple data types? If she can return a cursor which version is it possible?
  Thank you!

  Hi Mark,

  Some examples of the REF Cursor code.

  CREATE OR REPLACE FUNCTION emp_by_job (p_job VARCHAR2,p_deptno NUMBER,pv_table VARCHAR2)

• Capture of high speed using flex functions returns null vector

  Hello

  We have a controller 7350 and UMI-7774 drive a motor step by step through P70530 pilot. We use a single axis, axis 1, which is configured as a stepper motor with your comments and 10000 steps/rev. Our engine performs a profile displacement and during this move, you should read the position of the encoder with about 2000 Hz resolution. I can move the engine using MAX or flex functions, I can also read the encoder using the post MAX, but cannot perform high speed reading.

  Issues related to the:

  1. How can I configure read it for 2000 Hz at high speed?

  Function flex_configure_buffer (boardID, bufferInEnc, axis, NIMC_HS_CAPTURE_READBACK, contMoveBufSize, totalPoints, NIMC_FALSE, requiredInterval, on actualInterval)

  Returns the error-70078 (invalid parameter) when I pass a required interval less than 10ms.

  2. How can I read data from buffer high speed?

  Even when the buffers is configured with the interval of 10 ms, the flex_read_buffer_rtn (boardID, bufferInEnc, rear, out retVector) function returns no data (retVector = null).

  Please find attached an example of solution of vs2008 demonstrating the problem.

  Hello Stephen,

  The problem is now solved, the problem was in the trigger condition.

  It seems that the parameter requiredInterval in the function flex_configure_buffer() function call is ignored, because I get to any interval of 0.5 ms data even if the requiredInterval and the actualInterval are two 10ms.

  Thanks for your help.

• Function return undefined values

  My function returns undefined values. It seems that the return of the function statement is executed before the database is queried and values are assigned to variables. If I do an alert within the loop for () I get the correct values from the database, but these values are not affected before excecuting the return statement function. How can I do this differently?

  function getColumnNames(table){
      var rs1, rs2, rs3, rs4, rs5;
      db.transaction(function (tx) {
          tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){
              var size = results.rows.length, i;
              var item;
              for (i = 0; i < size; i++){
                  item = results.rows.item(i);
                  rs1 = item.col1;
                  rs2 = item.col2;
                  rs3 = item.col3;
                  rs4 = item.col4;

                                  alert(rs1); //correct value is returned here
              }
          });
      });
      return [rs1, rs2, rs3, rs4, rs5];
  }
  

  Hey Fabian,.

  You are quite correct that the return statement is executed before the database returns the results. There are ongoing asynchronous calls. You can set breakpoints in JavaScript code to see what is happening. You can correct the problem by using function callbacks. I edited your code below to use the callback functions - there might be a few typos, but the general approach should be wooded.

  function getColumnNames(table, callback){
      var rs1, rs2, rs3, rs4, rs5;
      db.transaction(function (tx) {
          tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){
              var size = results.rows.length, i;
              var item;
              for (i = 0; i < size; i++){
                  item = results.rows.item(i);
                  rs1 = item.col1;
                  rs2 = item.col2;
                  rs3 = item.col3;
                  rs4 = item.col4;
                  rs5 = item.col5;
                      alert(rs5); //correct values are being returned
                  callback([rs1, rs2, rs3, rs4, rs5]);
              }
          });
      });
  }
  
  // example of how to call getColumnNames with callback
  getColumnNames('importantTable', function (result)
  {
      console.log(result);
  });
  
  // alternative version
  function onCallback(result)
  {
      console.log(result);
  }
  
  getColumnNames('importantTable', onCallback);
  

  I hope this helps.

  See you soon,.

• How the two function return values

  Dear all,

  Please explain, how the two values of function return?

  give a simple example.

  OK, a few examples...

  First example, using a type of structured on the database object:

  SQL > create or replace type tMyValues as an object (yr number, number, number of dy mn)
  2.

  Type of creation.

  SQL > create or replace function getMyValues return tMyValues is
  2 number of y: = extraction (year sysdate);
  number of 3 m: = extraction (sysdate months);
  number of 4 d: = extract (day of sysdate);
  5. start
  6 return new tMyValues(y,m,d);
  7 end;
  8.

  The function is created.

  SQL > set serverout on

  SQL > declare
  2 myValues tMyValues;
  3. start
  4 myValues: = getMyValues();
  5 dbms_output.put_line (' year: ' | myValues.yr);
  6 dbms_output.put_line (' month: ' | myValues.mn);
  7 dbms_output.put_line (' date: ' | myValues.dy);
  8 end;
  9.
  Year: 2015
  Month: 4
  Day: 1

  PL/SQL procedure successfully completed.

  Second example, using an associative array within PL/SQL:

  SQL > set serverout on
  SQL > declare
  2 type tMyValues is table of the index number to varchar2 (10);
  3 myValues tMyValues;
  4
  5 function getMyValues return tMyValues is
  6 retValues tMyValues;
  7. start
  8 retValues ('Year'): = extraction (year sysdate);
  9 retValues ('Month'): = extraction (sysdate months);
  10 retValues ('Day'): = extract (day of sysdate);
  11 return retValues;
  12 end;
  13. begin
  14 myValues: = getMyValues();
  15 dbms_output.put_line (' year: ' | myValues ('Year'));
  16 dbms_output.put_line (' month: ' | myValues ('Month'));
  17 dbms_output.put_line (' date: ' | myValues ('Day'));
  18 end;
  19.
  Year: 2015
  Month: 4
  Day: 1

  Back AFTER using the exception block is fine as long as your code actually REACHED the exception block.

  When there are no errors, then your code will not enter the exception block, but you still NEED to return a value, since it is what functions a function wants to return a value, that's what the functions are made for.

  Spot the differences between the following 3 functions. Understand how they work.

  The first function has only a return in the exception block but runs correctly. Result: error, because the back is missing in the code block.

  The second function has a return in the exception block and one in the block of code and runs correctly. Result: no error, because the return is not missing in the code block.

  The third function has a return in the exception block and one in the block of code and is forced into an error. Result: no error, because the return of the exception handler is used (instead of retriggering of the error, which you would normally do).

  Hi fac586,

  I couldn't thank you more. Of course, read you my code and found that the design of table is not reasonable. in fact I just design for the demonstration of the prototype, so do not consider architecture.

  I mean, it is that the problem has disappeared when I create a new page like this one, don't know how it happened. in any case what I need has been achieved, thank you very much for what you have done.

  Nothing. It is not possible to do this using a branch as the changing context of the browser should be initiated by the browser, not the server. Use JavaScript to do this automatically:

  window.open('', '_blank');
  

  I'd go with changing the direction if it branches to the original page, setting a value of ASK for use as a condition on dynamic action of The Execution of JavaScript Code that runs the window.open.

  Best regards
  Fateh

  Hello Faye,

  We are already aware of this problem, even if it is not yet present on our Web page of problems known. The reason for this error is that the new facility replaces an instance to the scale encryption key. In the preferences of the instance which have been encrypted with the old value (the SMTP password and the password for the portfolio), the values are not valid after the upgrade and decryption causes this error. As a work around, you can use the apex_instance_admin package to replace the invalid passwords.

  The following code shows how the decryption throws ORA-28817:

  SYS@a411> select apex_instance_admin.get_parameter('SMTP_PASSWORD') from dual;
  select apex_instance_admin.get_parameter('SMTP_PASSWORD') from dual
         *

  You can fix this by entering new password:

• How to make FUNCTION returns several columns and several outputs line

  Hi all
  
  Kindly share your idea; Thanks in advance;
  
  I have the demo of the Table.
  
  DEMO table:
  
  name identity
  1 to 10
  1-a11
  1-a12
  2-b10
  2-b11
  3 ccc
  
  and the function is like:
  
  create or replace function (number of p1) return varchar2 as
  number of vid;
  VNAME varchar2 (20);
  Start
  SELECT id, name in vid, vname from demo where id = p1;
  return v1;
  end;
  /
  
  This function returns the output for the id = 3;
  
  BUT,
  
  I need output like (input 1)
  
  VNAME vid
  1 to 10
  1-a11
  1-a12

  A function returns a single data type.

  This type of data can be a type of atomic data (varchar2, number etc.) or it may be a type of data object to save, or even a type of collection data.

  Where will you use this feature? In PL/SQL or SQL?

  If you are wanting to use it in SQL, need you a pipeline for example function

  If you use it in PL/SQL and then just filling a data type of collection and return that will make. Although you should question why you want to pass large amounts of data around like that first.

  Explain your purpose and what you intend to do and we can recommend the best way.

• The page validation: function returning a Boolean

  Hi guys,.
  
  I'm doing a page validation simple to check an element in my presentation table if it is a number or not:
  
  START
  FOR i IN 1.. apex_application.g_f12. COUNTY
  LOOP
  IF LENGTH (TRIM (TRANSLATE (apex_application.g_f12 (i), "0123456789","" "))) is NOT null
  THEN
  RETURN FALSE;
  END IF;
  END LOOP;
  END;
  
  but I get this error message if g_f12 = AAA:
  
  ORA-06502: PL/SQL: digital or value error: character of number conversion error
  ERR-1021 error cannot run the validation of the "body of the function that returns a Boolean.
  Ok
  
  If g_f12 = A12 or a mixed alphanumeric it will work!
  
  * (I tried this with the function returning the text and it works like a charm, but in this case I have to use the function returns boolean to allow me to translate the error message) *.
  
  am I doing something wrong please help
  
  Thank you

  Hello

  Well, now when I look at the error message, I think that the problem is quite obvious.

  Kind regards
  Jari
