• Update multiple columns from multiple tables in a single UPDATE request

  Hello

  I'm trying to figure if I'm heading in the right direction.

  I want to update multiple columns from multiple tables in a single UPDATE request. Also, I would like to update multiple columns in a table from the tables.

  Scenario 1

  UPDATE Table2, Table 3
  SET T2.Column1 = T1.Column1 
  ,T2.Column2 = T1.Column2
  ,T3.Column2 = T1.Column2
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T1.id = T2.id
  and T1.id = T3.id
  
  

  Scenario 2

  UPDATE Table3
  SET T3.Column1 = T1.Column1 
  T3.Column2 = T1.Column2
  ,T3.Column3 = T2.Column3
  ,T3.Column4 = T2.Column4
  FROM Table1 T1, Table2 T2, Table3 T3
  WHERE T3.id = T1.id
  and T3.id = T2.id
  
  

  Hello

  For scenario 1, you must write separate instructions UPDATE table2 and table3.

  To guard against someone else change one of these tables while you act so you can copy all relevant data in a global temporary table and update this global temporary table table3.

  ENGAGE only when two tables have been changed.

  You can write a procedure or an INSTEAD OF trigger to do all this.

  For scenario 2, you can reference many tables that you need when new table3.  It might be more efficient and simpler to use the MERGER rather than UPDATED.  For example:

  MERGE INTO table3 dst

  WITH THE HELP OF)

  SELECT t1.id

  t1.column1

  t1.column2

  t2.column3

  t2.column4

  FROM table1 t1

  JOIN table2 t2 ON t1.id = t2.id

  )             src

  WE (dst.id = src_id

  WHEN MATCHED THEN UPDATE

  SET dst.column1 = src.column1

  dst.column2 = src.column2,

  dst.column3 = src.column3,

  dst.column4 = src.column4,

• PL SQL program unit does not compile with cursor for UPDATE NOWAIT

  All,
  
  I am trying to use a cursor for UPDATE NOWAIT to avoid hung sessions on the shape of the front end.
  
  I am using a syntax such as:
  
  CURSOR my_cur (p_val)
  IS
  SELECT 1
  FROM my_table
  WHERE my_col = p_val
  FOR UPDATE NOWAIT.
  
  However, later in the procedure, when I try to refer to the cursor with the following syntax:
  (after opening/get the cursor...)
  
  UPDATE my_table
  SET my_col2 =: MY_BLOCK. FOO
  WHERE CURRENT OF my_cur;
  
  I get the following compilation error:
  Error 404 on line 140, column 30
  cursor 'MY_CUR' must be declared with to use with the CURRENT UPDATES OF
  
  The strange thing is that if I remove the "NOWAIT" keyword, the program unit compiles.
  
  If nothing else has noticed this? No workaround or patch solution? Is this a known bug?
  
  Thank you very much
  -Chris

  Try one

  FOR UPDATE OF ID NOWAIT;
  

  where ID is the name of a column in the table.

• UPDATE multiple columns with conditional parameters

  I have a procedure that updates several columns of a table using the parameter of the procedure. Is it possible to have a update unique with the parameter SET conditional statement?

  Please help gurus!

• Display and update of fields in different tables on the same page.

  I am facing two problems...
  
  (1) I have a report on which I show several fields of 4 different tables. For each row of data, there is a link to change on the first column. By clicking on the link change, I show you a form where I want to show the respective data. On the link change, even if I send you the data in the report, they do not appear on the form (what edit link is clicked). Also, there is only room for 3 items to ship through the link change.
  How to display the data correctly on the form? Is there another way to use the link change?
  
  (2) on the form, how do I update the data from different tables?
  
  Thank you

  Hi Lisa,

  The text of presentation on the INSTEAD OF triggers is in: [http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7004.htm#sthref7918]

  First of all, your SQL View contains a unique key so that your triggers and the two Apex know what is updated.

  Then, you can create instead of triggers for "instead of INSERT ON viewname", 'instead of UPDATE ON viewname' and 'DELETE ON viewname' on your SQL view. What do these triggers depends on what you need. In the trigger code, you refer to new data using: NEW.column_name and old data using: OLD.column_name (updates both: OLD and: NEW values).

  I'm not sure of the SEPARATE, the GROUP IN question. You would certainly have a unique key on each record. It could be that the DISTINCT or GROUP BY clause will have to be taken out of the SQL view and is part of the source of the region, so that the SQL view does nothing with the data other than to join several tables in a single "table" from the Primary Key/Foreign Key relationship.

• PL/SQL with cursor for update another slider

  END;
  
  ERR: PLS-00320: the declaration of the type of the expression is incomplete or incorrect
  
  Thanks in advance...

  Hello

  I see.
  My answer is always application: do not use the sliders if you don't have to. Looking for a way to do what you need to use only the SQL statements.

  If you really not to use the two sliders, where some values in a come on the other, you can have nested cursors.
  For example, the use of scott tables, you want to give a raise of 10% for all salaray everyone in any department based in a given city.
  You may have two sliders:
  (1) find each department based in the city of right
  (2) find every employee in the Department of (1)

  CREATE OR REPLACE PROCEDURE     slow_update
  (     in_city_name     IN     VARCHAR2
  )
  AS
       CURSOR     dept_csr     (target_loc     VARCHAR2)
       IS     SELECT     deptno
            FROM     dept
            WHERE     loc     = UPPER (target_loc);
  
       CURSOR     emp_csr     (target_deptno     NUMBER)
       IS     SELECT     empno
            FROM     emp
            WHERE     deptno     = target_deptno;
  BEGIN
       FOR     dept_rec IN dept_csr (in_city_name)
       LOOP
            FOR     emp_rec IN emp_csr (dept_rec.deptno)
            LOOP
                 UPDATE     emp
                 SET     sal     = sal * 1.1
                 WHERE     empno     = emp_rec.empno;
            END LOOP;
       END LOOP;
  END     slow_update;
  

  Notice how I used parameters in the sliders.

  You must perform the procedure as follows:

  EXECUTE  slow_update ('Dallas');
  

  Repeat: This is only for demonstration purposes.
  The smart way to do such an UPDATE does not require the sliders or PL/SQL:

  UPDATE     emp
  SET     sal     = sal * 1.1
  WHERE     deptno     IN     (
                 SELECT     deptno
                 FROM     dept
                 WHERE     loc     = UPPER (:target_city_name)
                 );

• Automatically update the column in the table in OBIEE

  Hi people,
  
  I have a requirement to say I need to update a column of table based on a condition, but this update should happen on a daily basis (I mean that it would be held once per day) by checking if all the records in this column meets the condition then update
  
  example:-column = 'pending', then using the "approved". As records of transactions every day in the table lights. OBIEE should check and update the line so the next time it does not show this line as "pending".
  
  I thought of 2 approaches to this
  (1) through the write-back, it is possible to update but manually (the question is it can't be automated or on demand on daily basis and update multiple records on a go)
  (2) write a stored procedure or a function of update, but how can I perform this procedure either regular or run once daily.how to use it?
  
  Any thoughts on the above two points or any method you can think off the coast.
  
  Any help is appreciated!
  
  See you soon,.
  KK

  Murielle,

  This shud be easy...
  -Create a direct database... with the Update statement
  for example: Update table set col = "Approved" where col = 'pending '.
  -Create an ibot using the RFI above and plan on a daily basis.

  This will update the complete table with the new value on a daily basis based on the State

• Update multiple rows in a table at a time

  Hi all
  
  I write a stored procedure that fills all columns in a table, that table with a query with the exception of a single column, say 'ABC' column in this table. I have to load this left on column using a different query that refers to some other tables. How can I update this column 'ABC' with all its rows of data from a different query?
  
  Thank you very much!!

  If you post an update with a create table and insert statements, it would be useful... I think that you want to update a table with a select from another table using a join... is that correct?

  c customer update
  Set client_name =)
  Select client_name
  of another_customer_table one
  where a.customer_id = c.customer_id_from_original_customer_table
  )
  where c.customer_id in (select customer_id from another_customer_table)

  Where clause is required only if you don't want to update missing customer_ids to null.

• Problem updating multiple rows in the table using subquery

  Hi everyone, I can't update multiple lines with a subquery. Here is the configuration:

  create table mytable (
  col_a number primary key,
  col_b number,
  col_c number,
  col_d number);
  
  insert into mytable values (1 ,1,1,15);
  insert into mytable values (2 ,1,2,7 );
  insert into mytable values (3 ,1,3,11);
  insert into mytable values (4 ,1,4,23);
  insert into mytable values (5 ,1,5,14);
  insert into mytable values (6 ,2,1,50);
  insert into mytable values (7 ,2,2,41);
  insert into mytable values (8 ,2,3,13);
  insert into mytable values (9 ,2,4,12);
  insert into mytable values (10,2,5,19);
  insert into mytable values (11,3,1,10);
  insert into mytable values (12,3,2,92);
  insert into mytable values (13,3,3,81);
  insert into mytable values (14,3,4,17);
  insert into mytable values (15,3,5,66);
  insert into mytable values (16,4,1,54);
  insert into mytable values (17,4,2,41);
  insert into mytable values (18,4,3,22);
  insert into mytable values (19,4,4,24);
  insert into mytable values (20,4,5,17);

  For this example, by using an update statement (or merge if this is better), I mean set values for col_d where col_b = 3 equal to that of the col_d where col_b = 1 and col_c equal between them. Results should resemble the following after the update:

  col_a col_b col_c col_d
  1     1     1     15
  2     1     2     7
  3     1     3     11
  4     1     4     23
  5     1     5     14
  6     2     1     50
  7     2     2     41
  8     2     3     13
  9     2     4     12
  10    2     5     19
  11    3     1     15
  12    3     2     7
  13    3     3     11
  14    3     4     23
  15    3     5     14
  16    4     1     54
  17    4     2     41
  18    4     3     22
  19    4     4     24
  20    4     5     17

  I see her there within my reach using this query, where I want to put b_col_d = a_col_d, but miss me something, this query returns too many rows when it is used in the update statement.

  select * from (
    select col_a as a_col_a, col_b as a_col_b, col_c as a_col_c, col_d as a_col_d
    from mytable
    where col_b = 1
    ) a, (
    select col_a as b_col_a, col_b as b_col_b, col_c as b_col_c, col_d as b_col_d
    from mytable
    where col_b = 3
    ) b
  where a.a_col_c = b.b_col_c

  Update column_d set mytable = (select? where?)
  
  Can someone help me get there? I use 10 gr 2.
  
  Thank you!

• How to upgrade all the record for a particular column in a table based on search criteria.

  Hi all

  I'm new to ADF. I have a requirement where I have to perform the update of mass on a table.

  Scenario:

  Ex: I have a search region manual dept. where I search with deptId: 20. I get 20 records in my table. now I have another area where I have an inputchoice list that contains all the column names that exist in the dept table. Beside that, I have a text box and a button update

  The user now, first research with dept id: 20 and click on the button Search, where it shows 20 record in the table. He then select an input choicelist(ex: ManagerId) column, then enter the new value in the decision-making box(ex: abc) then click on the button update.

  Now, I want to, all the records in the ManagerId column with dept id: 20 update with the new value 'abc '.

  Can someone help me with the code.

  Thanks in advance...

  Hello

  If you go to your VO and generate the ViewObjectImpl, here you can create a method that contains two parameters, 1 the name attribute and 2 the value.

  Then you can follow something as explained in this post:

  ADF tutorial: how to apply actions in bulk to a view object lines

  The only difference is that you must create a method like this:

  ' Public Sub updateAttribute (attribute String, Integer value) {}

  RowSetIterator iter = createRowSetIterator (null);

  While (iter.hasNext ()) {}

  Line = iter.next ();

  row.setAttribute (attribute, value);

  }

  }

  Then execute you who expose a customer interface and then after you filter your table according to your criteria just this method passing the correct parameters.
