Display the column names in a table

• 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

  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 the name of the tag as the column name and the value in the tag as a row of data from the input string.

  Hi Forum members,

  I am looking for a query display the name of the tag as the column name and the value in the tag as a row of data.

  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.

• How to export data to excel that has 2 tables with the same number of columns and the column names?

  Hi everyone, yet once landed upward with a problem.

  After trying many things to myself, finally decided to post here...

  I created a form in form builder 6i in which clicking on a button, the data gets exported to the excel sheet.

  It works very well with a single table. The problem now is that I cannot do the same with 2 tables.

  Because the tables have the same number of columns and the columns names.

  Here are the 2 tables with column names:

  Table-1 (MONTHLY_PART_1)	Table-2 (MONTHLY_PART_2)
  SL_NO	SL_NO
  MODEL	MODEL
  END_DATE	END_DATE
  U-1	U-1
  U-2	U-2
  U-4	U-4
  ..........	........
  ..........	........
  U-20	U-20
  U-25	U-25

  Given that the tables have the same column names, I get the following error :

  402 error at line 103, column 4

  required aliases in the SELECT list of the slider to avoid duplicate column names.

  So how to export data to excel that has 2 tables with the same number of columns and the column names?

  Should I paste the code? Should I publish this query in 'SQL and PL/SQL ' Forum?

  Help me with this please.

  Thank you.

  Wait a second... is this a kind of House of partitioning? Shouldn't it is a union of two tables instead a join?

• How to not display the column heading in the table view?

  I don't want to display the column header in the table display, how I can make?

  If you use JavaFX 8, you can use the following text in an external style sheet:

  .table-view .column-header-background {
    -fx-pref-height : 0 ;
  }
  

  If you use JavaFX 2.2, the - fx-pref-height attribute is not available in css, so I think that you must resort to a search:

  final Region tableHeader = (Region)table.lookup(".column-header-background");
      tableHeader.setPrefHeight(0);
  

  As always, I am obliged to point out that I don't really like the research. Sometimes, they seem to be the only way, however.

• Necessary emergency with a request: fill date of prior art on the column name

  Hello

  Can you please help me with the query. I would be grateful for your time and your help.

  I have the query and the following output. Basically, the query selects a date, a table and counties received documents based on the current date, day-1, - 2 days-, 3 days-4 days-5 days and especially 5 days. It's the query I wrote. Now the requirement has slightly changed and described below.

  Current query:

  SELECT SUM (CASE WHEN TRUNC (SYSDATE) TRUNC ( )File_Date() = 0 PUIS 1 AUTRE 0 FIN) Zéro ,

  SUM (CASE WHEN TRUNC (SYSDATE) TRUNC ( )File_Date() = 1 PUIS 1 AUTRE 0 FIN)   One ,

  SUM (CASE WHEN TRUNC (SYSDATE) TRUNC ( )File_Date() = 2 PUIS 1 AUTRE 0 FIN) Two ,

  SUM (CASE WHEN TRUNC (SYSDATE) TRUNC ( )File_Date() = 3 ALORS 1 SINON 0 FIN) Trois ,

  SUM (CASE WHEN TRUNC (SYSDATE) TRUNC ( )File_Date() = 4 PUIS 1 AUTRE 0 FIN) Quatre ,

  SUM (BOX WHEN TRUNC (SYSDATE) TRUNC (File_Date) = 5 THEN 1 ELSE 0 END) Five ,

  SUM (CASE WHEN TRUNC (SYSDATE) TRUNC ( )File_Date() > 5 PUIS 1 AUTRE 0 FIN) OverFive ,

• Select the column name when the value = something

  Is there a way to select the column name when there is a specific value in it?

  As follows:

  create table (abc123)

  COLUMN1 VARCHAR2 (50).

  COLUMN2 VARCHAR2 (50).

  Column3 varchar2 (50)

  );

  insert into abc123 values ('yes', 'Yes', 'No');

  insert into abc123 values ('no', 'Yes', 'No');

  INSERT INTO ABC123 VALUES ('no ',' no', 'No');

  insert into abc123 values ('yes', 'Yes', 'Yes');

  SELECT CASE WHEN COLUMN1 = 'Yes' THEN - the name of the column would be here somehow?

  WHEN COLUMN2 = 'Yes' THEN - the name of the column would be here somehow?

  WHERE Column3 = 'Yes' THEN - the name of the column would be here somehow?

  Another null

  finish as abc123 columnname

  final results for the just Column1 would be:

  COLUMN1

  NULL VALUE

  NULL VALUE

  COLUMN1

  I'm not sure what I use to get the name of column in there

  Thank you.

  Thanks for posting the CREATE TABLE and INSERT for the sample data.

  Don't forget to post the exact results you want from these sample data.  If the results depend on the parameters you want to pass a run time, then give a few different examples, with the the desired results of each.

  You can hardcode the values you want, such as the column names in a query.  For example:

  SELECT CASE WHEN column1 = 'Yes' THEN 'Column1' END like y1

  CASE WHEN column2 = 'Yes' THEN 'Column2' END like y2

  CASE WHEN Column3 = 'Yes' THEN 'Column2' END like y3

• Can I use * and the list of the column names in a select query

  PLSQL again.  Can I use * and the list of the column names in a select query, i.e. Select *, col1, col2 from Mytable.  When I do that my questions tend to the bomb.  Can do in other databases.

  Thank you

  Hi, Mike,.

  If there is something else in the more SELECT clause *, then * must be qualified with a table name or alias.

  For example:

  SELECT Mytable. *, col1, col2

• How to display the member name and/or Alias according to generation in Studio EN?

  I have a report that contains relatives in lines that are set to stretch and show Member aliases. During the expansion under the parent I would like to display the member name and Member Alias. I tried conditional formatting to replace the Alias members using a text function, but replace only accepts text, not functions. Does anyone know how to do this?

  I use 11.1.2.3

  Do you need to in the same column? If this isn't the case, you could pull in another column of the alias and use conditional formatting to hide either or depending on the generation.

• Rename the column name of the view

  Suppose I have an employee of the table with the column name. Now, I want to make a view of the employee to the table with the name of the First_name and Last_name column. Is this possible?

  You can also use aliases in the view definition:

  CREATE VIEW employee_view (
    first_name,
    last_name
  ) AS
    SELECT first,
           last
    FROM   employee;
  

  However, you can rename a column in a view. You would have to DROP and CREATE or to CREATE or REPLACE.

• use a (selection list) element as the column name in the select?

  I have a popup LOV key based on a select (dynamic list of values)
  I want to display and return - select columns in the select statement to be determined by another list.

  but then I don't you the value of: P133_COLUMN... so if: P133_COLUMN is 'EMPNO' LOV popup displays the text "EMPNO" and referred the text 'EMPNO', not the empno column values...
