• How to make reference to a column name in the domain constraint

  When specify us a constraint check (for SQL Server) in a field, we need to enter an expression in the syntax, for example
  
  Len (Phone) > 7
  
  Later, the Modeler will exactly this expression in the SQL code. But it would be wrong as a constraint to refer to a column name in the table (which would not be 'phone').
  So, how to make the data name Modeler to a real column in the constraint domain?

  Hello

  Use the % COLUMN as a placeholder column name - len (%COLUMN%) > 7

  I have to print the values within the tag to a file by choosing the value of the flags. the sequence of the tags will vary each time, as the tag name will change dynamically.

  So here is the example of input data and the expected output. The string in the text column must be separated as the column names and values.

• new to 4.02, no grid or column names in the query results

  It is a bit strange, I have SQL Developer 4.02 just installed, and I don't see grid or column names in the query results.  Don't see anything useful in tools > Preferences, what don't get me?

  The worksheet gives you a couple of different ways to run a query...

  1. instruction execute sheet icon toolbar (large green arrow, or Ctrl + Enter).

  This produces a results tab of the query with the data displayed in a grid.

  2. worksheet icon toolbar Execute the Script (the small tip of the green arrow on lined paper, or F5).

  This produces a tab out of the Script with the data displayed on the printer.

  If execution of the statement to Execute the Script, using some SQL * most orders will remove the column headers:

  1. set the position

  2. set the pagesize 0 (or 1 or 2).

  Pagesize and linesize default is - 1.  By default, the spreadsheet is free for formatting output script as he wishes.  If you have not changed these settings in the spreadsheet, then see if you point to a startup script in Tools > Preferences > Database > name of the connection startup script file

  Kind regards

• Display the column name of the column more recently updated

  I wonder if it is possible to display the name of the column in the column most recently updated in a table.

  Example:

  Emp table

  Name

  Height

  Weight

  Age

  Update_Date

  Update_Column

  Original record (03/20/14)

  Name size weight Age Update_date Update_Column

  John                                                 03/20/14          Name

  Then someone comes and update the height on 22/03/14:

  Name size weight Age Update_date Update_Column

  John 5'9 03/22/14 height

  And the Update_date and the Update_column would change again if someone came and put a value for the age. And so on.

  Is this possible?

  Also, if the above is possible, would it be possible to display the name of extreme right column if a user updated several columns at the same time?

  Example:

  User updates the sub-folder:

  Name size weight Age Update_date Update_Column

  John 5'9 03/22/14 height

  And adds weight and age at the same time on 24-03-14:

  Name size weight Age Update_date Update_Column

  John 5'9 150 31 03/24 / 14

  The Update_Column would display age because it is the furthest to the right. (Think by reading from left to right, the column that has been updated if the extreme right)

  So to sum things, I need to be able to display Updated_date (which will be the date of the day when the record is the last updated) and Updated_Col (which is the column name of the column was last updated, and if multiple columns are updated then display that value has been updated last in)

  I hope that the examples help to clarify things.

  Thank you

  Steven

  I think I found a solution.

  delimiter //
create table a (
  id int (10) unsigned auto_increment,
  a int(10),
  b int(10),
  update_date datetime NULL,
  update_column varchar(16) NULL,
  primary key (id)
)//

  create trigger bu_a before update on a for each row begin
  set NEW.update_date = NOW();
  set NEW.update_column = NULL;
  -- you need to start with the rightmost column if you want
  -- that matched with the highest priority
  if OLD.b != NEW.b then
   set NEW.update_column = "b";
  elseif OLD.a != NEW.a then
   set NEW.update_column = "a";
  end if;
end //

  TEST

  insert into a (id,a,b) values (1,1,1), (2,1,1), (3,1,1), (4,1,1)[
update a set b = 2 where id = 2;
update a set a = 2 where id = 3;
update a set a = 2 where id = 4;
update a set b = 2 where id = 4;
select * from a;

  DISPLAY

  ID  A   B   UPDATE_DATE                    UPDATE_COLUMN
1   1   1   (null)                          (null)
2   1   2   March, 24 2014 23:22:33+0000      b

  As an alternative to the linesize parameter, you can format the columns:

  SCOTT>col module for a30
  SCOTT>select status, machine, module

  How to use several adf 12 shape and insert the form data in to table during the click on "submit" button. Can we use several form from adf or not?

  Make sure that you dragged the VO based EO.

  Also make sure that the VO attributes based EO Updatable property.

  The query according to VO is used only to add LOV to the column of the original VO ModelId.
