• 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.

  or

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

  Hope this helps,

• Conditional looping. How to check the previous result s of closure?

  Hello

  I would like to repeat a sequence for the second time if the sequence is not the first time. To do this, I would use the loopback step properties feature. Question: How can I build the loop State Expression referring to the step of Staus (pass/fail) of the first loop?

  In loopback loop Type properties, select number of pass/fail.  Then assign the stop after 1 and iterations to pass.  You can set the maximum number of iterations to any value you want (in your case, it sounds like 2).  You can play with the numbers to fit your scenario.  As you play with the numbers, you'll see the values of the changing expressions.

  I could give you a better answer if I understand exactly what you wanted but it will probably do what you want.

• trigger check the previous record of line before insert/update

  Hi all

  I would like to create a trigger that a customer will not be able to create a new account, if it has a status of "Non-payment".

  CustomerID custNRIC paymentStatus

  ----------------------------------------------------------------

  Non-payment of 200 F7654323A

  It will reject the following statement.

  insert into customer (custID, custNRIC, paymentStatus) VALUES (201, 'F7654323A', 'Good');

  so, how can I go around to solve this issue?

  You can't do things like that in a trigger.

  It will reject the following statement.

  insert into customer (custID, custNRIC, paymentStatus) VALUES (201, 'F7654323A', 'Good');

  The trigger would dismiss as EVERY other row in the same transaction, if you try to use a trigger.

  You can't stop a trigger to run except by raising an exception and the trigger stop from doing anything for ANY line that the trigger activated on.

  together to define

  CREATE OR REPLACE TRIGGER reject_new_account

  AFTER INSERT OR update ON the client

  FOR EACH LINE

  DECLARE

  PRAGMA AUTONOMOUS_TRANSACTION;

  totover NUMBER (3);

  BEGIN

  SELECT COUNT (*)

  IN totover

  OF THE customer

  WHERE: NEW.nric = customer.nric

  AND: NEW.badstatus = "Non-payment";

  Why are you tring to use an autonomous transaction? All that makes the transaction will NOT be part of the transaction that fired the trigger.

  I know there is a problem with the line 13 ' AND: NEW.badstatus = "Non-payment".»

  so, how can I go around to solve this issue?

  This is the LEAST of your problems. Do NOT try to nontransactional things in a trigger.

  Also, don't try to query the table that the trigger is activated on.

  This is the fundamental question: Oracle is a multi-user system. Other users may be perform DML on the same table at the same time. So any NUMBER that provides this trigger can turn out to be inaccurate when other users post their transactions.

  The best you can do in a trigger is throw an exception. If you do this will affect the complete relaxation and all the lines he treated - not only one line you see that you want to reject.

  A requirement like yours needs to be satisfied by the presence of DML performed using functions or procedures and serialize the customer INSERT/update this transaction that a SINGLE session/user/can perform DML on the table for a client given.

  Hello

  That's what you asked for in Oracle 10:

  SELECT       a.*
  ,       CASE
             WHEN  action = 'break'
             THEN  LAST_VALUE ( CASE
                                  WHEN  action = 'fix'
                                  THEN  author
                                 END
                                 IGNORE NULLS
                             ) OVER ( PARTITION BY  id
                                             ORDER BY      tmstmp
                                  )
         END        AS lastfixby
  FROM       actionhistory         a
  ORDER BY  id
  ,            tmstmp
  ;
  

  Like all of the built-in functions, LAST_VALUE is documented in the manual of the SQL language:

  ... just in case where it might be useful, one of the queries I've tried myself a left subquery joined that Oracle has no right ("a column may be outside not attached to a subquery').

  Much more, it would help if you posted the request.
  It looks like you were using the old outer join notation (+). You can get the desired results by using an outer join with ANSI rating, but I think it would be more complicated and slower than with a LAST_VALUE.

  OK, problem solved by myself:

  IF: System. CURSOR_RECORD! = 1 and: global .rec_changed = 0 THEN

  : global .rec_changed: = 1;

  PREVIOUS_RECORD;

  : global .fec_hasta: = to_char(:cret_prod_pol_renovacionesb.crpn_fe_hasta,'DD-MM-YYYY');

• Satellite A200 - how to check the temperature of the processor fan?

  Hi all

  I have a Satellite A200 that my teenagers use a little, or abuse a little! Recently, it would not start up. I suspect the fan and pulled out the fan cleaned and tested the fan on a PSU, worked out well. He put it back together, ran startup repair and now the computer is operating normally. The fan is however not appear to come at all. In the Device Manager it tells me it works very well. I'm all good with the mechanical side of the House, but I'm a quamby operating system! How to check the temp CPU or fan?

  Thought that replace the fan but don't want to go that far just to get no results. Currently using the vacuum on low like an external fan and didn't want to just run the laptop with no cooling for fear of permanent damage. Although children watch movies with her on their doona may have already reached this!

  Any advice would be appreciated.

  Hey mate,

  How to clean the fan exactly? It s advisable to use the jet of compressed air. This could blow the dust of fans cooling and, therefore, it of not necessary to disassemble the laptop.

  In addition if the fan doesn't work anymore it of necessary to replace. You can order spare parts at an authorized service provider.
