• In the form of table-update of rows based on the selection of the checkbox

  Hi all
  
  I have a tabular layout with line selector. I need to update manually checked columns, how would write a process audited records updated?
  
  Something like this:

  BEGIN     
       FOR i in 1..apex_application.g_f01.count LOOP
  
            IF apex_application.g_f01(i) is not null THEN
                 UPDATE TEST_USERS
                      set USER_ID = :P14_TO
                 WHERE rowid = :APEX$ROW_ID;
                 COMMIT;
            END IF;
       END LOOP;
  END;

  Thank you very much.

  You can refer to the line that you want to process through the value stored in the box.

  If you use apex_application.g_f01 (i) to make reference to the line and you want to update the row based on the ROWID in your request, your SQL query should have the box as follows:

  apex_item. CheckBox2 (1, rowid)

  Then your PLSQL process would be like this:

  BEGIN
       FOR i in 1..apex_application.g_f01.count LOOP
  
            IF apex_application.g_f01(i) is not null THEN
                 UPDATE TEST_USERS
                      set USER_ID = :P14_TO
                 WHERE rowid = APEX_APPLICATION.G_F01(i);
                 COMMIT;
            END IF;
       END LOOP;
  END;
  

  I hope this helps.

• Compare multiple columns and update a column based on the comparison

  Hi all

  I have to update the column STATUS of the slot structure of the table.

  Status should be 'P' if all the columns count are equal on the other should be "F".

  The value of the column can be "NA'. If the value is NA, then avoid this comparison column; compare only other 3 columns.

• update of column based on another column

  Hi all
  
  I want to update the column 2 of the table based on the value of update in column 1 and the existing value in column 1
  
  Assume that table1 has columns ID, col1 and col2
  
  I update col2 based on the update to col1 value and comparing the existing value of col1 in the table.
  
  trying to decode, I think it should work.
  
  Thank you.

  Not like that.

  You change a column of type CHAR, VARCHAR2 column, right? Thus, the data will be same. (Completed with space). For the new data inserted into a column VARCHAR2 TRIM is not necessary.

• update of column based on the sum of the data from another table

  I have two tables:

  Table1 (col1, col2, col3, col4, val1, status) Table2 (col1, col2, col3, col4, val2)

  For Table1 and Table2, column (col1, col2, col3, col4) are the primary key of composit.

  Table2 could have duplicated lines, that's why I want to group by (col1, col2, col3, col4) and sum (val2)

  After that, I want to update Table1.val1 with the value of sum (Table1.val2) where Table1.col1 = Table2.col1 and Table1.col2 = Table2.col2 and Table1.col3 = Table2.col3 and Table1.col4 = Table2.col4 and status = 'V '.

  I did something like this:

  UPDATE Table1 SET val1 = (

     

  WHERE Table1.col1 = t_sommevbrute.col1 and Table1.col2 = t_sommevbrute.col2 and Table1.col3 = t_sommevbrute.col3 and Table1.col4 = t_sommevbrute.col4)

• Update a column-based

  Hi all

  Let us examine below in Oracle 11 g:

  create table xx_test1 (line_num  number, line_group_num number, type varchar2(25));
  
  
  insert into XX_TEST1 values('',1, 'ITEM');
  insert into XX_TEST1 values('',1, 'TAX');
  insert into XX_TEST1 values('',2, 'ITEM');
  insert into XX_TEST1 values('',2, 'TAX');
  insert into xx_test1 values('',3, 'ITEM');
  insert into xx_test1 values('',3, 'TAX');
  

  I want the line_number update based on type and line_group_num columns column.

  So necessary result:

    LINE_NUM LINE_GROUP_NUM TYPE
  ---------- -------------- ----
           1              1 ITEM 
           2              2 ITEM 
           3              3 ITEM 
           4              1 TAX  
           5              2 TAX  
           6              3 TAX  
  

  That means I want the sequence to be - items in the first place, only the lines of the TAX.

  Line_group_number is the column that combines the tax line to the line item.

  Any ideas?

  Regrads,

  You can do this by using the ROW_NUMBER function analytical in a MERGE statement.  For example:

  MERGE INTO dst xx_test1

  WITH THE HELP OF)

  SELECT line_group_num, type

  ROW_NUMBER () (ORDER BY TYPE, line_group_num) AS line_num

  OF xx_test1

  )              src

  WE (dst.line_group_num = src.line_group_num

  AND dst.type = src.type

  )

  WHEN MATCHED THEN UPDATE

  SET dst.ine_num = scr.line_num

  ;

  This assumes that the combination (type, line_group_num) is unique, and none of these columns are NULL, like your sample data.

  If this isn't the case, then the above statement needs to be changed a little, but only a louis577.

• Comparison of column in the form of table II

  Hello
  
  At the APEX 4.1 I am doing something similar to this thread: in table form: compare two fields in column where I need to do a validation on two columns in tabular form. It works for both columns are columns of text box, but I can't make it work when comparing to a single column to display. For validation, I have defined it as an "Expression of PL/SQL" and my expression is: CURRENT_VALUE >: PREV_VALUE where CURRENT_VALUE is a column of text box that accepts user input and PREV_VALUE is only one display column.
  
  Regardless of the absorbed power, the row is updated without any errors raised; He seems to treat the single display value in the vacuum and made the comparison with an empty value. The only solution I could find was to make the comparison in a update trigger on and will raise an error if validation fails; but the result is not as nice as the built in features of validation of the APEX.
  
  No indication on how to make it work using the validation of the APEX is greatly appreciated.
  
  Thank you!

  Only column display are for display only and are not saved in the session when you send, so that you can't access with pl/sql.

  So either do the validation in javascript/jQuery or, and it is best if you ask me, make a text field and set to read-only.

  What you're doing results in the engine of the APEX, P24_CASE_NAME 'C254DB' value in the default value and then try to assess this string as a piece of PL/SQL. Outside a block in which it is defined as a variable, constant, or a function 'C254DB' is not a valid expression of PL/SQL.

• Column of link does not work on a manual in the form of table

  Hello
  
  I'm having some problems by creating a link on a column based on a tabular presentation manual (I use Apex 4.1.1.00.27, Oracle DB 10.2.0.5.0):
  
  On my 1 page, I created a method that deletes and creates a collection based on the table 'emp '; Then I have a manual tabular presentation based on this collection; and finally, a link in the column "deptno" of the manual tabular form that points to my Page 2 (form of Department) and is passing the P2_DEPTNO parameter: #DEPTNO #.
  
  The problem is that when I press on the link, the page does not present the value of DEPTNO. In addition, I note that as soon as I specify the column as a column of link, it does not show the value in the form of my table, but if I remove the link, it shows the value correctly.

• update to column values (false) in a copy of the same table with the correct values

  Database is 10gr 2 - had a situation last night where someone changed inadvertently values of column on a couple of hundred thousand records with an incorrect value first thing in the morning and never let me know later in the day. My undo retention was not large enough to create a copy of the table as it was 7 hours comes back with a "insert in table_2 select * from table_1 to timestamp...» "query, so I restored the backup previous nights to another machine and it picked up at 07:00 (just before the hour, he made the change), created a dblink since the production database and created a copy of the table of the restored database.
  
  My first thought was to simply update the table of production with the correct values of the correct copy, using something like this:
  
  
  Update mnt.workorders
  Set approvalstat = (select b.approvalstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  where exists (select *)
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  
  It wasn't the exact syntax, but you get the idea, I wanted to put the incorrect values in x columns in the tables of production with the correct values of the copy of the table of the restored backup. Anyway, it was (or seem to) works, but I look at the process through OEM it was estimated 100 + hours with full table scans, so I killed him. I found myself just inserting (copy) the lines added to the production since the table copy by doing a select statement of the production table where < col_with_datestamp > is > = 07:00, truncate the table of production, then re insert the rows from now to correct the copy.
  
  Do a post-mortem today, I replay the scenario on the copy that I restored, trying to figure out a cleaner, a quicker way to do it, if the need arise again. I went and randomly changed some values in a column number (called "comappstat") in a copy of the table of production, and then thought that I would try the following resets the values of the correct table:
  
  Update (select a.comappstat, b.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi - this is a PK column
  and a.comappstat! = b.comappstat)
  Set b.comappstat = a.comappstat
  
  Although I thought that the syntax is correct, I get an "ORA-00904: 'A'. '. ' COMAPPSTAT': invalid identifier ' to run this, I was trying to guess where the syntax was wrong here, then thought that perhaps having the subquery returns a single line would be cleaner and faster anyway, so I gave up on that and instead tried this:
  
  Update mnt.workorders_copy
  Set comappstat = (select distinct)
  a.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi
  and a.comappstat! = b.comappstat)
  where a.comappstat! = b.comappstat
  and a.workordersoi = b.workordersoi
  
  The subquery executed on its own returns a single value 9, which is the correct value of the column in the table of the prod, and I want to replace the incorrect a '12' (I've updated the copy to change the value of the column comappstat to 12 everywhere where it was 9) However when I run the query again I get this error :
  
  ERROR on line 8:
  ORA-00904: "B". "" WORKORDERSOI ": invalid identifier
  
  First of all, I don't see why the update statement does not work (it's probably obvious, but I'm not)
  
  Secondly, it is the best approach for updating a column (or columns) that are incorrect, with the columns in the same table which are correct, or is there a better way?
  
  I would sooner update the table rather than delete or truncate then re insert, as it was a trigger for insert/update I had to disable it on the notice re and truncate the table unusable a demand so I was re insert.
  
  Thank you

  Hello

  First of all, after post 79, you need to know how to format your code.

  Your last request reads as follows:

  UPDATE
    mnt.workorders_copy
  SET
    comappstat =
    (
      SELECT DISTINCT
        a.comappstat
      FROM
        mnt.workorders a
      , mnt.workorders_copy b
      WHERE
        a.workordersoi    = b.workordersoi
        AND a.comappstat != b.comappstat
    )
  WHERE
    a.comappstat      != b.comappstat
    AND a.workordersoi = b.workordersoi
  

  This will not work for several reasons:
  The sub query allows you to define a and b and outside the breakets you can't refer to a or b.
  There is no link between the mnt.workorders_copy and the the update and the request of void.

  If you do this you should have something like this:

  UPDATE
    mnt.workorders     A      -- THIS IS THE TABLE YOU WANT TO UPDATE
  SET
    A.comappstat =
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B   -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  WHERE
    EXISTS
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  

  Speed is not so good that you run the query to sub for each row in mnt.workorders
  Note it is condition in where. You need other wise, you will update the unchanged to null values.

  I wouold do it like this:

  UPDATE
    (
      SELECT
        A.workordersoi
        ,A.comappstat
        ,B.comappstat           comappstat_OLD
  
      FROM
        mnt.workorders        A      -- THIS IS THE TABLE YOU WANT TO UPDATE
        ,mnt.workorders_copy  B      -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
  
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    ) C
  
  SET
    C.comappstat = comappstat_OLD
  ;
  

  This way you can test the subquery first and know exectly what will be updated.
  This was not a sub query that is executed for each line preformance should be better.

  Kind regards

  Peter
