• Need to retrieve the last line/record in a table

  Hello
  
  I have a requirement like getting the ending balance of the last record in the table and the same insertion in the opening balance of the immediatetly created the next record.
  
  In simple terms, I need to extract a value from the last line of the recording.
  
  For example, I use the query below
  
  Select rownum emp, empno, ename
  where rownum = (select count (rownum) from emp);
  
  But, the above query does not return all of the recording.
  
  Therefore, need help on this.
  
  Kind regards

  Hello
  Strictly speaking there is no such LAST or FIRST folder until that order you them.
  But check the following:

  SELECT * FROM emp MINUS
  SELECT * FROM emp WHERE rownum<=(SELECT count(empno)-1 FROM emp);

  Is it possible to get this result from the discussion I see that oracle does not maintain insertion order unless you have a specific column to keep track of changes and insertions.

  Thanks in advance

  Of course; If you can tell which way these 2 rows are the last 2: can someone show you how do it.

  They are the last 2 in order by empno?  If so:

  WITH got_r_num AS

  (

  SELECT ename, empno, mgr, hiredate, sal, comm, deptno

  , EVALUATE () OVER (ORDER BY empno DESC) AS r_num

  FROM scott.emp

  )

  SELECT ename, empno, mgr, hiredate, sal, comm, deptno

  OF got_r_num

  WHERE r_num<=>

  ;

  Is this another thing that makes the last 2 rows?  If so, change the analytical ORDER BY clause.

• Get the updated record the last based on the Date and the van of the user ID corresponding (multiple tables)

  Hello people,

  I currently have a working for this using PL/SQL solution, but it would be nice to have it using SQL. Any help is appreciated and once again, to your practice time.

  I'm looking to pick up the most recent date and the corresponding user that updated registration for a student in particular. There are two tables T1 and T2. The most recent date can be the create_date or modified_date of T1 or T2.

  Scripts for creating the table and INSERT statements:

  create table T1
    ( code           varchar2(4),
      create_date    date,
      create_userid  varchar2(20),
      modified_date  date,
      modify_userid  varchar2(20));
  
  create table T2
    ( code           varchar2(4),
      visit_id       number,
      visit_date     date,
      create_date    date,
      create_userid  varchar2(20),
      modified_date  date,
      modify_userid  varchar2(20));
  
  

  insert into T1 values ('1001',to_date('06-FEB-2013 09:12:12','DD-MON-YYYY HH24:Mi:SS'),'ROGER',to_date('12-APR-2013 13:01:12','DD-MON-YYYY HH24:Mi:SS'),'BRIAN');
  insert into T2 values ('1001',1,to_date('10-JAN-2013','DD-MON-YYYY'), to_date('10-JAN-2013 14:12:12','DD-MON-YYYY HH24:Mi:SS'),'ROGER',to_date('12-MAR-2013 12:01:06','DD-MON-YYYY HH24:Mi:SS'),'AMY');
  insert into T2 values ('1001',2,to_date('31-JAN-2013','DD-MON-YYYY'), to_date('12-MAY-2013 16:11:12','DD-MON-YYYY HH24:Mi:SS'),'GRACIE',null,null);
  
  insert into T1 values ('1002',to_date('12-JAN-2013 11:12:13','DD-MON-YYYY HH24:Mi:SS'),'LYNNELLE',to_date('12-APR-2013 13:01:12','DD-MON-YYYY HH24:Mi:SS'),'BRIAN');
  insert into T2 values ('1002',1,to_date('10-JAN-2012','DD-MON-YYYY'), to_date('10-JAN-2012 09:12:12','DD-MON-YYYY HH24:Mi:SS'),'ROGER',to_date('12-APR-2013 13:04:12','DD-MON-YYYY HH24:Mi:SS'),'AMY');

  I want to show for the three codes are the following records:

  Code      Table Date                              User ID
  1001      T2  12-MAY-2013 16:11:12   GRACIE
  1002      T2 12-APR-2013 13:04:12   AMY
  1003 T1 04-FEB-2014 12:01:01 LYNNELLE
  
  

  1001 students, the most recent is the create_date of the visit count = 2 for the Code 1002, the most recent date comes from modified_date for visit 1 (its 3 seconds later than the T1 modified_date). Finally, for students 1003 (who did not all records in T2, the create_date is the only date and must be picked up.

• Update the records in the table

  I have an INCOME_LOT table. Now, I need to update records with the current max (lot_id) + rownum where lot_id = 0.
  Note: There are multiple records with lot_id = 0.

  CREATE TABLE INCOME_LOT
  (
  LOT_ID NUMBER OF NON-NULL,
  NUMBER OF DETAIL_ID
  DATE OF EFFECTIVE_DATE,
  DATE OF UPDATE_DATE
  )
  It is only a sample data of 4 records, while in fact, I have millions of records to be updated.

  Insert into INCOME_LOT
  (LOT_ID, DETAIL_ID, EFFECTIVE_DATE, UPDATE_DATE)
  Values
  (0, 5773490, TO_DATE (MAY 5, 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (MAY 6, 2014 00:22:40 ',' DD/MM/YYYY HH24:MI:SS'));))
  Insert into INCOME_LOT
  (LOT_ID, DETAIL_ID, EFFECTIVE_DATE, UPDATE_DATE)
  Values
  (0, 5773491, TO_DATE (MAY 5, 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (MAY 6, 2014 00:22:40 ',' DD/MM/YYYY HH24:MI:SS'));))
  Insert into INCOME_LOT
  (LOT_ID, DETAIL_ID, EFFECTIVE_DATE, UPDATE_DATE)
  Values
  (0, 5773492, TO_DATE (MAY 5, 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (MAY 6, 2014 00:22:40 ',' DD/MM/YYYY HH24:MI:SS'));))
  Insert into INCOME_LOT
  (LOT_ID, DETAIL_ID, EFFECTIVE_DATE, UPDATE_DATE)
  Values
  (0, 5773493, TO_DATE (MAY 5, 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (MAY 6, 2014 00:22:41 ',' DD/MM/YYYY HH24:MI:SS'));))
  COMMIT;

  Can someone help me to update all records with a single SQL query or maybe a PL/SQL block? I could design a cursor to update, but it would be tedious to use.

  Do you want this:

  UPDATE INCOME_LOT

  Set lot_id = 262696 + ROWNUM

  WHERE lot_id = 0;

• Record in the table don't is not updated correctly after sail of detail page

  I have 2 jspx pages (page A) a table showing the employee record, another a (page B) is used to update the file of the selected employee. On the page, when the button select a folder and clicking on the 'details' I may be navigaed at pag B on which I can edit registration information in a form component. I have a table column 'Prospect', which applies to a LOV layer VO pageB I use < af:inputComboboxListOfValues > to display a combo of LOV for this attribute, when I enter a new value here and save it, I can go back to page one, but the name of the team for this record shows empty, by querying the database that I find the record updated successfully with the changed value. And when I reloaded the page this record may indicate the new team name value. Why it is not updated in the employee table, when browsing immediately return of page B? I put the table attribute to 'always', but always refresh iterator not. Can anyone help with this? Thank you!!
  
  BTW, for the other columns (not LOV), they are ok, the table can display the value correctly.

  Not possible as your data model do not answer for him. As simple as that.

  If there is a need to determine an order or associate some time to an entity, then that should be part of the data model - and a relationship, or one or several attributes are necessary to represent this information. Your data model in this case is therefore unable to meet your requirements.

  If the requirements are valid, set the data model. In other words - your question has nothing to do with Oracle and nothing to do with the other pseudo columns in Oracle, the rowscn or the rowid. It is a question of pure data modeling. Nothing more.

• How to insert the last updated date and user id to a form?

  Hello
  
  I created a form to enter data into a custom table.
  When a new record is created, I want to keep track of the date created, last updated date, and who (user id) enters the form.
  
  Can you please help or point me to a good place to look for this information?
  
  Thank you!
  LC

  Create four new columns in your table called Created_On, Created_By, Last_Updated_On and Last_Updated_By.

  You can create a trigger for the rest:

  create or replace trigger ""
    before insert or update on ""
    for each row
  begin
    if inserting then
      :NEW.Created_On := sysdate;
      :NEW.Created_By := v('APP_USER');
    end if;
  
    if updating then
      :NEW.Last_Updated_On := sysdate;
      :NEW.Last_Updated_By := v('APP_USER');
    end if;
  end;
  

  Whenever you will add or modify data in this table, the trigger will automatically fill these fields.

  Kind regards

• iPhone 6plus iOS 9.3.5 since the last update my touch screen is freezing. Has yet to be decided. Connection to the computer did not help. I had to wait my battery died to restart. Once restarted I could use touchscreen but it now

  It is a list of the problems I have with my iPhone 6plus since updating to IOS 9.3.5.

  1. A single date after update my touch screen froze and I was unable to trouble or to use until the battery died and the phone has rebooted.
  2. Since this restart my touch screen hangs for 5 minutes at a time at least 5 times per hour.
  3. My screen goes completely black 20 seconds in the reading of an article. I have to refresh my browser at least 6 times by reading an article on the web.
  4. If I'm in iBook I can't read yet a page without the screen goes black. I hit the home back to iBook button try to keep reading where I left off the coast, but within 20-30 seconds it goes back to black.
  5. While I'm typing, even this message, I hit the button of the space and the words are charged or inserted which does not appear. I myself taking much time to type anything bc I have to go back and get rid of the words that the phone has decided to him only to change or insert.
  6. Improvements that never going to this last day f__d my phone. Difficulty what you did in the last updated bc I will eventually lead to an Apple Store and throw the phone home.

  What have I tried to fix it. Everything. For many in the list and you already know what the normal things are that the average person would be difficult it phone. I have no problems until I updated to iOS more recent so caused my problems of telephones you people. PLEASE FIX NOW

• Mozilla, your last update does not include the last cert of intermediaries of extended validation from Verisign, Symantec class 3 EV SSL CA - G2, please fix ASAP

  Your last update of firefox, Mozilla does not include the last cert of intermediaries of extended validation from Verisign, Symantec class 3 EV SSL CA - G2, please fix ASAP

  Firefox never includes the intermediate certificates.
  It is the responsibility of a server to include all the intermediate certificate required to make it possible to build a certificate chain that ends with a trusted root certificate embedded.

  Note that Firefox automatically records the intermediate certificates that servers send in certificates for future use Manager (they appear labelled as 'Software security device' in the References tab).
  If a server does not send a complete certificate chain then you get an untrusted error when Firefox has stored missing intermediate certificates to visit a server in the past that a send it, but you get an untrusted error if this intermediate certificate is not yet registered.
