  < cfquery datasource = "RTW_ORA" name = "cn" >
  SELECT COLUMN_NAME
  OF ALL_COL_COMMENTS
  WHERE TABLE_NAME = ' #meas #
  < / cfquery >

  obtain data: -.

  < cfquery datasource = "RTW_ORA" name = "cd" >
  SELECT *.

  Your question is not stupid. You can use the concept of a query requestand their properties cfquery attributes name and result.

  
  SELECT *.
  To #meas #.
  

  
  
  
  

  
  
  column names: #column_names #.
  
  number of columns: #no_of_columns #.
  
  
  

  
  SELECT #column_names #.

• How to extract the names of file/URL of all files in a folder (in the same directory of site)?

  I am creating an online music player, simple Flash-based; the user clicks on a song in a DataGrid, and then he plays, simple. I displays the information of the song with the ID3 method in the class 'sound', but I don't want to hardcode all the songs in the ActionScript code, because I change them. I created a folder "tracks" in the directory of the site; How can I extract the names of the files in this folder without knowing how many there are by nature, and files without knowing the URL?

  Use PHP or another script server to read the contents of the folder and to deliver the names of files for Flash in the form of data (xml or txt).

• How to extract the values of column aliases based on different column values?

  Hello gurus,
  
  I have a table with the following struture-
  

  "drop table T;

  'Anderia', 'AA', 1050000,'HR' from dual union all select
  'Michael', 'ML',150000,'Sales' from DUAL union all select

       , dep

• How to change the name of column in table effectively

  Hello
  
  I use JDev 11.1.1.4.0.
  
  My JSF page is done with 3 or 4 EOs, your and LOVs. However, one of the EO tables has changed its column name. The name change is important for the standard project.
  
  I remember having a lot of harm in changing a prior column name (I had to start over), so I would ask the experts take on how to do it without too much impact.
  
  This particular column is an OT, VO and lives as a field test on a JSF page.
  
  All comments or suggestions will be greatly appreciated.
  
  Thank you
  
  Bones Jones

  Indeed, the only thing you would have to change is the ColumnName of the object attribute specific entity (name of column of data in the attribute from entity dialog box). Now, if you used sync with databases... feature you will need to go through a full process of refactoring. In this case, use the menu refactor in JDeveloper. See if anything on this post can help you to: http://jdeveloperfaq.blogspot.com/2010/04/faq-20-how-to-refactor-adf-components.html

• the number of columns in dynamic sql

  Hello
  
  I was wondering if you could count the number of columns had a dynamic sql code.
  
  Very simple eg.
  
  Say I had a string 'select 1, 2,3,4,5,6 double' and I only immediate excute. Is it possible to count the number of column IE 6 columns.
  
  I know s/n | THE USER | ALL_TAB_COLUMNS, but it could be a few different columns columns, and it is not a view.
  
  Thanks for you advice/help.

  with the "immediate execution" option you cannot get metadata such as the number of columns for the executed query. Use rather dbms_sql...

  Research of DESCRIBE_COLUMNS string in the link below... It will give you an idea of how to make to get the same.

• How to dynamically change the names of columns LOV

  Hello

  I use JDeveloper 11.1.1.4

  I have only one requirement, while I need to change the names of columns in the list of values dynamically.

  How can I achieve it.

  Please help me.

  Kind regards

  John.

  Hello

  > But I want to change the column names 'ID' and 'Name' dynamically.

  Based on what? Condition? If Yes, have you tried to set the text for the label as an expression? If not based on the condition, you can also expose the VO to Java Impl and need a way to get the attribute and change its label.

  Make a prompt like:

  SELECT case when 1 = 0 then 'D0 time. " "" T02 by month name "other" 'D2 market' '. "" M04 region' ' the end 'Sample Sales' UNION ALL SELECT case when 1 = 0 then 'D0 Time. " "" T02 by month name ' else ' 'Time D0. "" T02 by month name ' ' the end 'Sample Sales.

  Put the name of column in single quotes.

  Make your rank as a function:
  Rank ('F1 income'. "" Recipes 1-01 (after all) "by @{pColumn} {'D0 time'. ({"" T05 annually name '})

  It works fine for me

  Anyone has a solution please?

  Asuming LIBL_x columns have the same type or a base at least type

  then the changes above can help you.

  In addition, you can write your cursor loop in a loop "for i in (select...)."

  you don't need to write that match the code, but it is cosmetic.

  See you soon
