followed by the name of the column that is changed

Hello

How can I track the following information on a table

I have the name of table tab1, that's like that

--------------------------
col1 col2
-------------------------
1 2

Now if I change the value of col1 by a trigger I can follow the value of change, but how can I track the name of the column

say in the table tab2 I am tracking the results

changed_col_name changed_val prev_val
--------------------------------------------------------------

now changed val and prevval can be followed by trigger, but in the column changed_col_name how can I follow the name of the column to which I changed?

Thanks in advance

It's a pain to dynamically manage the column in a trigger.

  • The column that does not match when comparing two records

    Hi all

    We try to compare two tables and find the differences. So if two records (1 of each table) have same PK but not always matching because of some columns, then we would display this columnname. For example:

    Table 1

    PK Parent Child Property1 Property2
    1AA1P1PR1
    2BB1P2oraPR2
    3CC1P3SRP

    Table 2

    PK Parent Child Property1 Property2
    1AA1P1PR1
    2BB1P2PR2
    3CC1P3PR4

    In the above example when I compare 2 tables all matches except Property2 online n ° 3. Thus, we would like to get an output like:

    PK Column_Mismatch
    3Property2 (this must be the name of the column that does not match)

    Appreciate the help.

    Thank you

    Why you don't want no matter what exit for pk = 2?  Property2 does not correspond either to pk.

    What happens if the 2 columns (or more) do not match?  The following query would produce a list delimited, such as ' parents; PROPERTY2 '.

    WITH got_mismatch AS

    (

    SELECT pk

    , CASE WHEN t1.parent <> t2.parent THEN '; PARENT' END

    || CASE WHEN t1.child <> t2.child THEN '; CHILD ' END

    || CASE WHEN t1.properry1 <> t2.property1 THEN '; PROPERTY1 ' END

    || CASE WHEN t1.properry2 <> t2.property2 THEN '; PROPERTY2 ' END

    AS the offset

    FROM table_1 t1

    JOIN table_2 t2 ON t2.pk = t1.pk

    )

    SELECT pk

    , SUBSTR (incompatibility, 3) AS column_mismatch

    OF got_mismatch

    WHERE mismatch IS NOT NULL

    ;

    If you would care to post CREATE TABLE and INSERT statements for your sample data, and then I could test this.

    The query above does not count NULL values as inadequate.  If you want that, the same basic approach will work, but you can use DECODE instead of <> to compare columns.

    What happens if a pk exist in a table, but not the other?  You want an outer join, where I used an inner join above.

  • APEX do not allow to change the lines of the columns that are the primary key?

    I have pictures:
    http://img508.imageshack.us/my.php?image=21269582oe8.jpg


    Book (id_book - 'Primary key', title, year); book_author (id_author id_book - 'Primary key', - 'Primary key'); author (id_author - "Primary key", name)



    I created a new page-> Form-> form of 'author' table because I want to add new authors, modification and deletion. During the creation of this page, I have chosen column 'id_author' as '1 primary key column' and everything is OK (I can't edit the 'id_author' column - this column is autoincrement and I can change the 'name' column).

    BUT I also created a new page-> Form-> table for table "book_author" because I like to write numbers like id_book and id_author, change and remove them (so add relations between tables: book, book_author and author). During the creation of this page, I have chosen column 'id_book' as '1 primary key column' and 'id_author' as 'column primary key 2'. And on the Web site, I can't edit these fields. And I can not add also new line because I see in each new line: (null).

    APEX do not allow to change the lines of the columns that are the primary key? It's stupid... What can I do?

    Edited by: user10731158 2008-12-20 11:40

    Column unique and not meaningful if you ever want to update. In the case of your example, you need to add an ID column in the intersection of book_author table. Honestly, I was so blown away (and pleasantly surprised) by the absence of rebuttal and the "thx" I advanced and set up an example of how I would define the book_author table:

    create table  book_author
   (id varchar2(32),
    book_id varchar2(32),
     author_id varchar2(32),
     modified_on     date,
     modified_by varchar2(255),
     constraint book_author_pk primary key (id),
     constraint book_auth_book_fk foreign key (book_id) references books(id),
     constraint book_auth_author_fk foreign key (author_id) references authors(id)
     )
/

create unique index book_author_uq on book_author (book_id,author_id)
/

create or replace trigger  biu_book_author before insert or update on book_author
for each row
begin
     if inserting then
          :new.id := sys_guid();
     end if;
     modified_on := sysdate;
     modified_by := nvl(v('APP_USER'),user);
end;
/

  • My iTunes playlist display has changed and I can't control the columns that appears? My old playlists are very good.

    OK, I make playlists for radio broadcast. I need to change the columns shown, and it has always been easy. The playlist I created just has a different view, and there seems to be no way for me to change the columns that are visible. Any ideas?

    Click Show main menu, and then click Show the Options. You can select the columns that you want or do not want to here.

  • The user can only download the columns that I choose?

    Hey, guys:

    Is that possible I put somewhere in the APEX so that the user can download only the columns that I choose instead of all the columns in the report, that this user can see, like some columns of links that directs the detailed individual pages? It makes no sense for the user to see these columns in a CSV file.

    Thank you.

  • Is it possible to make a reflection of the image that will change with the image? [was: reflection]

    Is it possible to make a reflection of the image that will change with the image?

    I believe that a dynamic object will solve your problem.

    Place your original image to a new file as a smart object and do the same for reflection (made by processing, reducing the opacity and introduce a slight blur horizontal) on its own layer, then:

    by double clicking on the smart object in the layers panel and return to the original image, any change in the original and save, automatically update the vertical image and its reflection.

  • Table with list of value to load on another value of the column that is never changed by the user

    Nice day!

    I work with JDeveloper 11.1.2.4.

    I have a Table of the ADF that has 4 lines.  Each row has a column with a unique value.  The plan should include a LOV column in the row show a different list of values based on a single column value.  I have install the list of values, use a display with a variable binding criterion.  When you create the data LOV source, I Specifies the name of a single column for the value of the bind variable.  However, it seems that the LOV changes none selecting different lines.

    Is there a good way to handle this?  I did LOVs of person in charge in the past, but this isn't quite the same as the user can view only the value that depends on the LOV on.

    Any suggestions are greatly appreciated!

    Hey, it's always a case of use of the dependent list of values. If the attribute that you bind the bind variable view criteria at part of the view object then the value LOV to be examined accordingly.
