  Hi Craig,.

  Thank you for your information.

  But I found the exact cause of this "Invalid cursor error' (ORA-01001) in Oracle forms. It is because of the unique enclosed in quotes the select statement of the REF cursor. I found in the paragraphs below Oracle.

  Note 170881.1 - ORA-1001 calling a stored procedure that contains a REF Cursor Oracle Forms

  Once I deleted the quotes, it's working properly now.

  Thanks again for your help.

  Kind regards

• 'Image' of block multi-record element type

  If I have a block of several record with a type of picture element, is it possible to load only / display an image for some of the records on a datablock? It seems that "READ_IMAGE_FILE" still applies to the whole element, which is responsible for the image for all records in the block... I can't find anything that will load only the image of a certain recording that I said... Something as sort of 'SET_ITEM_INSTANCE_PROPERTY' where I can put the record number I want the image to display on. Such a thing exists?
  
  Thank you!

  If the item of the Image is based on a BLOB column, you can escape to the population of the order of the day. I see no work around. It's like you ask a record, but do not want to display the content of the column.

• Block multi Record

  Hello
  
  I have a block of several record and under certain conditions, I would disable lines that statisfies the condition
  
  I will check that the trigger in a TIMES NEW BLOCK INSTANCE.
  
  The problem is SET_ITEM_INSTANCE_PROPERTY it is an attribute of current_record, but do not know how to assign the condition current_record as the condition returns some value can only turn off the lines.
  
  Could someone help?
  
  Concerning

  Transfer your logic of an once - instance trigger new - block to a trigger after query on your block "block":

  IF: block.item = "SAVE" THEN
  SET_ITEM_INSTANCE_PROPERTY ('block.deptno', CURRENT_RECORD, INSERT_ALLOWED, PROPERTY_FALSE);
  ON THE OTHER
  SET_ITEM_INSTANCE_PROPERTY ('block.deptno', CURRENT_RECORD, INSERT_ALLOWED, PROPERTY_TRUE);
  END IF;

  But INSERT_ALLOWED no sense that the record exists, perhaps you mean UPDATE_ALLOWED?

• Querying a multi-record in my form block

  I have a form where I perform validations of items entered on my main block. I compare the value of the item entered an expected value and if they are different then an exception record must be created in a separate block, several recording in my application. A record on my main block can end up with several different recordings of exception in the block of multi-record. As a result, my validation must include determining if the user has already created an exception record for the article I'm validating in the block of multi-record.
  
  Is it possible for me to query and uncomitted, block multi-record in my form? Help would be greatly appreciated!

  That's what I meant with "loop on the block."

  Write a function, lets call it FK_CHECK_FOR_EXCEPTION, give in the code and the name of the element as parameters and let it returns TRUE if the exception exists, false otherwise:

  FUNCTION FK_CHECK_FOR_EXCEPTION(i_vcItem IN VARCHAR2, i_vcCode IN VARCHAR2)
  RETURN BOOLEAN IS
    bFound BOOLEAN:=FALSE;
  BEGIN
    GO_BLOCK('BLOCK_B');
    FIRST_RECORD;
    LOOP
      EXIT WHEN :SYSTEM.RECORD_STATUS='TRUE';
      IF     :BLOCK_B.ITEM=i_vcItem
         AND :BLOCK_B.CODE=i_vcCode THEN
        bFound:=TRUE;
        EXIT;
      END IF;
      EXIT WHEN :SYSTEM.LAST_RECORD='TRUE';
      NEXT_RECORD;
    END LOOP;
    RETURN bFound;
  END;
  

  Then, in your VALIDATION KEY, you can something like:

  IF =FALSE THEN
    IF NOT FK_CHECK_FOR_EXCEPTION('ITEM1', 'THECODE') THEN
      RAISE FORM_TRIGGER_FAILURE;
    END IF;
  END IF;
  

• have a multi-record with several unrelated elements blocking, filled by simply calling

  Forms of oracle, I have a form with a block of several recording, with several unrelated elements.
  One of these non-is a basic formula element.
  The formula for this article fills the others not consolidated items.
  A procedure with several out parameters is called.
  
  For example
  : cmr.id (now the unique id of a database record)
  : cmr.unbound_dummy, with the formula f_fill_blk_unbound_items(:blk.id)
  : cmr.unbound_adres
  : cmr.unbound_contactperson
  
  function f_fill_blk_unbound_items (p_id in customers.id%type)
  Return number
  is
  number of l_rc;
  Start
  customer_pck.get_adres_and_contactperson
  (p_id = > p_id - IN)
  , p_adres = >: cmr.unbound_adres - OUT
  , p_contactperson = >: cmr.unbound_contactperson - OUT
  );
  Return (0);
  end;
  
  QUESTION: How can I do something similar in the APEX; have a blocking of multi-record with several elements not related, filled by calling a procedure with several out parameters?

  The suggestion refers to functions in pipeline
  http://www.Oracle-Developer.NET/display.php?ID=207

  This will allow you to select your information you need in a query like

  SELECT * FROM TABLE(table_function)
  

  It should also more powerful than the example of forms.

  Mano,

  Add NEXT_RECORD just before the END of the LOOP.

       GO_BLOCK('');
       FIRST_RECORD;
       LOOP
            IF NVL(:., ' ' ) = ' ' THEN

• How to do the validation to the record level in multi record block.

  Hello
  I use form 10g. I have a doubt in form 10g. Look, I got multi-record block (10 records).
  In this block, I have a few items of text
  (1) S_NO
  Account_number 2)
  withdraw_amt 3)
  Deposit_amt 4)
  (5) balance_amt.
  
  These are the fields and sample data that I posted in forms.
  S. n ACC_No - WITHDRAW_AMT - DEPOSIT_AMT - BALANCE_AMT
  1-250 - 1000.00 - 1000.00
  2.------250-----------500.00-------------------------------------------500.00
  3-250 - 2000.00 - 2500.00
  
  
  Now, I entered the data manually in all areas...
  But what I need is if I entered the field of deposit in the amount it will add to the old balance and if I add the amount to remove the field that he removed from the old balance automatically.
  Pls tell me what are the possible ways to implement this form...
  
  
  Eliane.

  For the calculation of the fields there are some properties, you can define and then let the calculation forms. The WHEN-VALIDATE-POINT-approach will not work, because it increases your balance_amount whenever you change the value.

  But what exactly is the logic for your calculation. It's just: BALANCE_AMT =: DEPOSIT_AMT-: WITHDRAW_AMT?

  If so, create a new database item not in the block, assign Calcaulation-mode of 'Formula', a formula to something like

  NVL(:BLOCK.DEPOSIT_AMT,0)-NVL(:BLOCK.WITHDRAW_AMT)
  

  Then whenever you change DEPOSIT_AMT or WITHDRAW_AMT, the BALANCE_AMT will be calculated again.

• Multi-record acquisition and fetch registration number

  My question relates to the fact an acquisition multi-record and go look for more than one record by extraction, but less than the total number of records.

  Let's say I am absorbing N records and go pick up j at a time where 1<>

  Hi EDD,.

  You are right that the "Fetch Record Number" property is adjustable to i * j in this case. Given that I have is starting from scratch, it works wonder. However, you need to make sure you stop the loop after the right amount of documents were recovered, which will be asked to configure the correct logic. This could be kept simple if you pick a divisor of your total of records every time, but if not, you will need to determine when you are on the last iteration, and the number of records you have left to seek before arriving at the end of your files.

  For example, if you are purchasing records total N = 100 and go for j = 10 at a time, you can simply extract I * j every time and to know when to stop, simply take (I * j) + j > = N. It works fine when j is a divisor of N integer, but otherwise, most logical should be included to determine the number of records can be left at the end, and then to seek a large number. Hope this helps,

• Fetch the multi-record acquisitions takes too long

  Hello

  I need to improve the performance of my code in multi record acquisition on the following system.

  LabVIEW 2009, Niscope 3.5.2 map 5122 digitizer on the PXI-1042 with PXI-8106 controller connected to the host PC Dell Optiplex 380 with 4 GB of RAM by crossover cable.

  I tested the speed of transfer of my connection to the chassis using the niScope memory transfer Rate.vi Maximum flow, the result was 110,74 MB/s.

  I need to use the scanner to get the waveform of different seismic sensors and it should be as fast as possible to get different transducers in a reasonable time. I used the Multi files get VI to monitor the rate at which the code executes. I want to acquire 30 signals with 10,000 record length to 100 MECH sampling rate. / s.

  Extraction of 30 records with 10 000 record length takes about 300 ms, that is far too long for my experience. I tried different numbers Records and found that the code takes 10 milliseconds per registration type. I've found that extraction vi takes most of the time. I ran my code both recording Multi search vi. Two sleeves at the rate which is not satisfactory for my application. I appreciate if someone can help me solve the problem.

  Thank you

  Ahmad

  .

  I found that on the pulse generator FRP was set at 100 Hz, which means it sends the impulse evey 1/100 sec or each 10 m I think the program was waiting to acquire the signal. I changed the FRP at 1 K Hz, it became much more quickly.

  Thank you

• How to check the previous value of the element in a multi-record block

  Oracle Version: 10 g
  Forms Version: 10 g
  
  Hi all
  Hello everyone, I have a multi-dossier block in a form where one of the values of elements is of LOV.user can select the value of LOV.
  
  If once the user selects the value of LOV and moves to the next of the multi-file record, and selects the value of LOV again, I shouldn't allow users to select the previous value of the user in order to avoid duplication of records.
  
  and important remark is that I should get there before you save it in the database because once registered in the database I can compare the values and hide the previous value.
  
  
  Any help will be appreciated.
  
  
  Thanks and greetings

  This is a question frequently asked in the forum! There are several different solutions. Take a look at the following articles. Both will perform the necessary verification of duplicates.
  Forms - registration of treatment group (value in double check...
  or
  Avoid records duplicated in a block

  If none of these solutions don't work for you, search the forum for other options.

• Relative position of a form of multi-record Record in a block

  Hi all

  I have a block record multi with number of items displayed in the 16. This block is used to fill the data in the table that can contain 100 records. When I scroll down the block for a record 39 said individual, I get the value of current_record than 39. But how do I know its relative position, that is to say which position he is currently now out of these 16 files that are displayed. Is there a way to manipulate it.

• Cannot access the multi-record block

  Hi friends
  
  I am facing a problem in one of 6i.
  
  On the form:
  In our form, we have two tabs:
  
  Tab1: We're looking for an order
  
  Tab2: Lists all commands
  
  Problem:
  When we have two tabs enabled, then I am able to move through the records of Tab2 (keyboard and mouse)
  
  However when Tab1 is disabled, so I am not able to navigate through the folders in Tab2 (keyboard or mouse)
  It has scrollbar in Tab2, when I drag the scroll bar, and then I am able to navigate through folders block2, but still not with the mouse.
  
  Limit of naviagtion of mouse is form
  For the block gives problem: elements have keyboard navigable Yes
  
  
  
  I do not understand this behavior, that is our requirement for some tab1 user will be disabled

  Hello

  u think to tab1 to user2 invisible so pending a TIMES-NEW-FORM, you can use to have...

  GO_BLOCK...
  GO_ITEM...
  

  I doubt that will help me with that: If the 2 trigger is executed after 1

  WHAT is the name of the trigger you want to know about his execution?

  I hope this helps...

  Kind regards
