• What is the role of the RETURN clause in a pipeline service?

  I wrote several functions in pipeline and they work fine without the return clause. However, in the oracle documentation he returns in pipeline positions:
  

  CREATE FUNCTION StockPivot(p refcur_pkg.refcur_t) RETURN TickerTypeSet
  PIPELINED IS
    out_rec TickerType := TickerType(NULL,NULL,NULL);
    in_rec p%ROWTYPE;
  BEGIN
    LOOP
      FETCH p INTO in_rec; 
      EXIT WHEN p%NOTFOUND;
      -- first row
      out_rec.ticker := in_rec.Ticker;
      out_rec.PriceType := 'O';
      out_rec.price := in_rec.OpenPrice;
      PIPE ROW(out_rec);
      -- second row
      out_rec.PriceType := 'C';   
      out_rec.Price := in_rec.ClosePrice;
      PIPE ROW(out_rec);

  In addition, at least in PL/SQL developer I receive advice that my pipeline functions return no values, well as I said features operate smoothly. So is it necessary in the return clause in the functions of pipeline or is redundant?
  
  My version of oracle is 11.2.0.2.0

  You can find it in the documentation (you linked):

  A function table pipeline must have a RETURN statement that does not return a value. The RETURN statement transfers control to the customer and ensures that the next extraction Gets an exception NO_DATA_FOUND.

• How to remove the name of the column in the select clause

  Hello guys,.
  
  I want to just delete a column name in the select clause. Because I don't want to write all the names of columns. I hope I am.
  
  In other words, I want the following.
  

  Select   * - unwanted_column  from table;
  
  instead of this 
  
  Select col1, col2, col3, col4, ........ col 10000 from table;

  Hello

  There is nothing in SQL, which means "all columns * except *...» ». As others have said, the only way to achieve these results in SQL is to list all the columns you want.

  Your front end may have a feature that allows you to hide a specific column. For example, in SQL * Plus, you can use COLUMN... NOPRINT , like this:

  COLUMN      dname     NOPRINT
  
  SELECT       *
  FROM       scott.dept
  ORDER BY  dname
  ;
  

  Output:

  `   DEPTNO LOC
  ---------- -------------
          10 NEW YORK
          40 BOSTON
          20 DALLAS
          30 CHICAGO
  

  There is a column called dname in the scott.dept table; the query above uses actually. But, because of the order of the COLUMN, SQL * Plus will not display this column.

• massive many update column of the cursor?

  I have the problem of finding how to make an update of several columns using the update statement block (if possible). I know how to do it using merge or correleated update, I just want to know how to write using features in bulk by pl/sql. Here's the code for the sample tables:
  

  create table emp_tmp as select empno, job, sal, comm from emp where deptno = 30;
  update emp_tmp set sal=1000, comm=200, job='CLERK';
  commit;

  Now, I want to update original emp table with job, sal, comm emp_tmp table for some empnos. So I write:
  

  declare
    cursor c is ( select e.empno, t.job, t.sal, t.comm
                  from emp e, emp_tmp t
                  where e.empno = t.empno
                  and e.empno > 7700 );
  begin
    -- ... here I would like to use bulk feature for update statement on emp
  end;

  I can't understand the syntax above idea in bulk using statements. Could you give me some advice about this? How it should be written?
  
  Thank you

  A sample:

  declare
    cursor csr is ( select t.empno, t.job, t.sal, t.comm
                  from emp_tmp t
                  where t.empno > 7700 );
   type t_emp is table of csr%rowtype;
   t_emp1 t_emp;
  begin
    open csr;
    loop
      fetch csr bulk collect into t_emp1 limit 100;
      forall i in 1..t_emp1.count
        update emp
        set sal = t_emp1(i).sal
        where empno = t_emp1(i).empno;
      exit when csr%notfound;
    end loop;
    close csr;
  end;
  

• You will need to insert update column with the username?

  Hi all
  
  I'm new to this forum of the apex. New to apex as well.
  
  My question is do we have a form and a single column is editable by the user. whenever an update to this column, I need to write their name in the update column.
  
  I heard that we can do with trigger using the variable app_user. But in our project, they made authentication ldap for this form and when an employee login with their company login id they can see only this form of apex. no other option.
  
  In the same form, they were able to show the user name. I checked how they did it. they used * & user * variable for this. , It makes sense for you gentlemen?
  
  all I have to do is insert this & user in the column value.
  
  How to do this. I'm started working in the apex for the past four days alone. willing to bare with me if im a very stupid question.
  
  Thank you
  knani
  
  PS: I know that what im asking is the user name for the Web page the user name of the apex.
  
  Published by: kart on May 26, 2010 11:45

  Hello

  You can use: APP_USER substitution string.
  If you like to use that in the syntax of database trigger is v('APP_USER') for example

  :NEW.CHANGED_BY := NVL(v('APP_USER'), user);

• How to update columns with the value of other lines in the same table

  Hello
  
  I use Oracle 11.2, I'd use SQL statements to update a column based on values in other rows in the same table. Here are the details:
  
  create table TB_test (number 4 myId, crtTs date, date of MDPU);
  
  insert into tb_test (1, to_date ('20110101', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110201', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110301', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110901', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110902', 'YYYYMMDD'), null);
  
  After you run the SQL code, I would like to have the following result:
  
  1, 20110101, 20110201
  1, 20110201, 20110301
  1, 20110301, null
  2, 20110901, 20110902
  2, 20110902, null
  
  Thanks for your suggestion.

  I guess you need this, otherwise please explain logic correctly:

  SQL> merge into tb_test t
    2  using (
    3    select rowid as rid
    4         , lead(crtts) over(partition by myid order by crtts) as updts

    8  when matched then update
    9   set t.updts = v.updts

  I don't know a lot of your application, but if you build it near standard forms (e.g. base your blocks on the tables), then its standard Frédérique you type the new value in the field and press save. the button... do you want to the "economy"? then put a DO_KEY ('COMMIT_FORM'); in it.

• email accounts + updated column on the page of the options not available

  Hello, sorry to ask this, but I can't find a similar problem on the community forum:

  I tried to change the look of my Thunderbird and switched in Vertical mode, now all the options in the view > page layout are empty, no way to change it back...

  Second question: while I was managing the columns in layout with the cursor, the one on the left with all accounts, now gone, there seems to be no way to recover it. It appears when I run Thunderbird for a fraction of a second, then nothing.

  I even removed Thunderbird and installed it again, but it opens with the same layout.

  Is there anyway that I can change to the default layout?

  Thanks for any help.

  Are you using a Add ons? If so restart with Add ons disabled in order to see if it works better. Helps in the menu.

• Columns in the WHERE clause - order affect the output?

  I work on some queries to feed a DWH and stumbled upon this question. Let's say I have this query:

• Update or merge it with the return data

  Hello, I want to do an update in a single statement, and select (I want to get the data and update a field in one of the tables involved with a timestamp), I tried this:

  merge into table t

  using (SELECT ... a long and complex select...) e

  on (e.ID = t.ID)

  When matched then

  update the value t.ts = systimestamp

  e return

  It does not work because his return does not seem possible with the merger, he did the update but I get no data...

  With an update, I tried:

  Update

  (

  SELECT...) e

  Aliens set = systimestamp

  And I get ORA-01779: cannont change a column that maps to a table of key-preserver nonkey.

  The select is complex with many paintings and selects involved and more than 20 KB of text only select... and this isn't mine so I want a solution that does not need to change the internal selection if possible.

  Any ideas? Sorry for my limited knowledge of sql :-(

  No, you did not read what I said.  The RETURNING clause allows you to capture the details of the update table.  You may not have the details of the complex query that you use to determine the return lines.  There is no way in SQL to a single statement that updates a table and queries data from other tables at the same time.

  The best you're going to manage is to update the data, turning the ID (or regardless of the primary key is appropriate) and then query the query data complex where once again the ID in your collection.  However, it's really messy.  What US the real purpose of all this?

• parent ID column in the outbreak of the child

  Hello

  It's Jean Philippe

  I use a sequence to generate the primary key column in the table emp

  How to insert

  Thank you

  You could use the RETURNING clause on your insert statement to get the value that the trigger is created and then use this value in your child table for example inserts

  SQL > create table emp_parent (ID, ename varchar2 (50), number of deptno)
  2.

  Table created.

  SQL > create trigger TrgEmpChild before insert on emp_child
  2 for each line
  3. start
  4: new.id: = generic_sequence.nextval;

  Hi, yes you can create a hierarchy of alternative for periods. For more information, see rolling forecast Web Form

• Slider with return return clause

  Hello
  
  What is the use of the cursor with return return clause?
  
  
  Thank you
  
  REDA

  Hello

  The return clause lets you create a specification for the cursor and always hide the implementation.

  So you can write in the specification of the package:

  CURSOR emp_cur (empno IN emp.empno%TYPE) RETURN emp%ROWTYPE;
  

  And then put in place the cursor in the body, as usual.

• DML with values returned of dml another inside the WITH clause

  Hello community, I want to use the ELECTION of an insert or update values to other insertion within a single transaction without staging of values returned. Here's what I mean. In some other dbs, I can do it like this

  WITH moved_rows AS)

  DELETE FROM products

  "WHERE purchased_date > = ' 2010-10-01' AND purchased_date < ' 2010-11-01"

  RETURN *.

  )

  INSERT INTO products_log

  SELECT product_id, product_date, sysdate, user moved_rows;

  I know the return value must be assigned to a local variable before they can be used within other dml, but I'm curious to know if the approach described above is supported in Oracle. Note that outside dml returns all columns (*) of the table products and then I took and chose the values I want to be inserted in the log table.
