  You don't realize that you have just set a UNIQUE INDEX of several columns?

  create unique index index_name_uq on table_name( user#, upper(item_name) );
  

  In addition, a GUI Design point, (using the terms of the APEX) that you want to validate the data before submit you.

• Trigger that avoids "is changing, function of triggering/can not see ' error

  Version Oracle 11.2.0.2

  I have a problem where I try to avoid duplicates in a table using a trigger.  Data looks like:

  EQUIP LO ACCT

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

  1000000000 0

  1000000001 0

  1000000002 0

  1000000003 0

  1000000004 0

  Equipment = equipment identifier

  Location = location number

  Acct = account associated with the equipment

  I need avoid the same account to have 2 pieces of equipment are allocated to the same location.

  for example

  EQUIP LO ACCT

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

  1000000000 1 1234

  1000000001 1 1234

  1000000002 0

  1000000003 0

  1000000004 0

  I can't create a unique index for this table that when there is no assigned equipment (first example) I couldn't have uniqueness through the location and number.  So, I wrote the following:

  CREATE or REPLACE TRIGGER TEST_TRG before update of test WE acct

  Old SEO AS OLD AS new NEW

  for EACH LINE

  DECLARE

  v_chk number: = 0;

  BEGIN

  Select count (*) in the test v_chk where acct =:new.acct and rental =:new.location;

  IF v_chk > 0 then raise_application_error ("-20001, ' multiple devices at the same location not allowed");

  END IF;

  END;

  /

  .. but of course that I'm shot in the table that is being updated, I get the error of mutation:

  setting a day of test set acct = "1234", location = '1' where equip = '1000000001'

  *

  ERROR on line 1:

  ORA-04091: table xxx. TEST is changing, function of triggering/can not see

  ORA-06512: in "xxx. TEST_TRG', line 4

  ORA-04088: error during execution of trigger ' xxx. TEST_TRG'

  I tried this split into two pieces where a trigger calls another procedure to perform the check and write error, but results were inconsistent and end-user demand does not pick up the error for a reason - it seems to process the transaction very well even if the update was not made at the table level.

  Are there other ways in addition to a trigger to achieve?

  Thank you!

  Thank you!

  Then also consider this value in your index of function according to:

  create table test

  (

  equip the varchar2 (10),

  location varchar2 (2),

  ACCT varchar2 (4)

  );

  CREATE a UNIQUE INDEX TestLocationAcct_UK ON Test

  (case when the ACCT is not null ACCT AND! =' ' then location |) « ; » || end of the ACCT);

  Insert test values ('1000000000 ', ' 0',' ');

  Insert test values ('1000000001 ', ' 0',' ');

  Insert test values ('1000000002 ', ' 0',' ');

  Insert test values ('1000000003 ', ' 0',' ');

  Insert test values ('1000000004 ', ' 0',' ');

  Update test set acct = "1234", location = '1' where equip is '1000000000';.

  Update test set acct = "1234", location = '1' where equip is '1000000001';.

  Error on line 1

  ORA-00001: unique constraint (SYSADM. TESTLOCATIONACCT_UK) violated

• ORA-04091: table that postal_address is changing, function of triggering/can not see

  First of all, there are any number of TRIGGERS defined on the table in question in our database.

  The process that we have to do is:

  1. load the addresses from the table.

  2. send the addresses by a routine of standardization.

  3. down any address that has been standardized with success and is not already present.

  So, how can I say ODI 12 c to create a temporary table before doing the multicables?  So far, everything I've tried gets 'flattened' and translates into the same error.

  OR

  Is there another solution?

  Thanks for your help,

  Scott

  I fixed that by creating a second physical + sense + model to this same base (not sure if I need all three, but because of this way to make sure).  This caused ODI generate a SOURCE_GROUP and TARGET_GROUP instead of just a TARGET_GROUP in the physical view.  I had to do everything on the properties of the first element in the target, set the properties on the Oracle of LKM Oracle shoot (DB Link). GLOBAL no matter what option I wanted to (USE_STAGE_TABLE or SELECT_FROM_SOURCE_VIEW).  One thing to do is put the database owner SID in the SOURCE_ACCESS_DB_LINK so it does not create an unnecessary DB link.

  Hope that helps someone else!

• Trigger - "Trigger is undergoing change, function of triggering/can not see.

  Hi all
  
  This is the first time I work with triggers. I have a question, because I don't understand how it works.
  

  create or replace trigger ctai_delivery
    after insert on delivery   
    for each row
  begin
    if :new.delivery_status_code is null then
      update delivery d
      set d.delivery_status_code = 'LEV'
      where d.delivery_number = :new.delivery_number;
    end if;
  end ctai_delivery;

  This trigger must run after an insertion. It will need to check if the inserted row delivery_status_code is not null, if it is, then fill it with 'LEVl.
  
  I read that you are not allowed to change the values of: news and: old. So, how can I change the value of delivery_status_code?
  
  Kind regards

• Microsoft Visual C ++ Runtime Error - can not see the path of the file.

  When I get the runtime at startup error, I don't see the destination of the file. It is very annoying that I can not see the program that gives me the problem.

  All it says, this is:

  Runtime error!

  Program: C:\Program F...

  How can I extend the above so I can see the path of the actual file?

  Also going to go for a 2 for 1 here...

  Immediately after the closure of the runtime error box, I get the message that search settings stopped working.  I close who and everything is fine until I reboot (by making the error happen) but I'd rather not have the problem in the first place.  I run Windows 7 Ultimate.

  Hello

  ·         Did you the latest changes on the computer?

  We must first identify to identify the program that is causing startup problems.

  Step 1:

  Check if the problem persists in safe mode.

  Start your computer in safe mode

  http://Windows.Microsoft.com/en-us/Windows7/start-your-computer-in-safe-mode

  Restart the computer to return to normal mode.

  If the problem does not persist in safe mode, then it is possible that some third-party programs installed on the computer is causing the problem.

  Step 2:

   

   

  I suggest that you put the computer in a clean boot state and check.

  To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  See section to learn more about how to clean boot.

  Reset the computer to start as usual

  When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

  (a) click Start, type msconfig in the search box and press ENTER.

  (b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

  (c) under the general tab, click the Normal startup option, and then click OK.
