• Discovered lines with column names where the cell contains a value

  I have a table with columns Additive_ID, A, B, C. Each Additive_ID has a single row.
  
  I would like to write a query that returns a result set with two columns: Additive_ID and values. It will have up to three lines for each Additive_ID, with the values column that contains the name of the column in the source table if it contains a 1 for this Additive_ID.
  
  What is the best way to achieve this?
  
  (In fact, the source table contains about 50 columns.)

  Select additive_id, decode(A,1,'A') value from your_table union all
  Select additive_id, decode(B,1,'B') value from your_table union all
  Select additive_id, decode(C,1,'C') value from your_table
  

  Here's a quick way to get all the SELECT to build the union:

  Select 'Select additive_id, decode('||column_name||',1,'''||column_name||''') value from your_table union all'
  from cols
  where table_name = 'YOUR_TABLE';

• ERROR DUPLICATE COLUMN NAME

  I get an error of duplicate column name to submit using automatic processing of line.
  
  I have a few items on the page with the same column name, but they appear under certain conditions. Even if I put in them NEVER occurs again.
  
  I would understand that you still can't duplicate names even if the elements are conditional?
  
  If this is the case, then Ill have to do with javascript or something. Pain cos apart from that, my form is quite clean
  
  Thanks for the help of anyones :-)
  
  Colin

  Since your sql does not deal with conditional columns, you don't CAN NOT use the same column name several times... Unless you write your own DML to manage updates/inserts & removes...

• How would add labels to lines and columns of a spreadsheet?

  I got some data of an oscilloscope, which has about 500 lines I want to the label at the time of measurement (1ms, 2ms, 3ms...) and about 10 columns I want to mark it with a corresponding wavelength (800 nm, 805nm, 810nm...). Any idea or links to examples would be appreciated.

  Gregory

  Before you write data in your spreadsheet file, write a line of column names.  Just make a table 1 d of strings with column names.  Write the 1 d array to the worksheet.  If you want labels on each line, you will need to convert your data into strings.  So, you will have a table 2D-string data.  Create a table 1 d of your line labels.  Insert in the table to insert your picture label in the data table, making sure to wire a 0 in the index of the column, not the index of the row.  This will put your labels in the first column.  Then write the 2D table in the spreadsheet file.

• How to select data using the same remote database column name 3

  Hello
  
  
  Can anyone help me on how to get the data with the same remote database column names 3 and a unique nickname.
  
  E.g.
  
  SELECT *.
  B.SID, b.status, SUM (b.qty) qantity MAX (b.) date_as_of
  Of
  * ((table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) has, *)
  (* (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) b). *
  WHERE b.dept = 'finance '.
  AND a.position = "admin".
  AND a.latest = 'Y' AND (b.status <>"MLT") AND b.qty > 0;
  B.SID GROUP, b.status;
  
  NOTE: the instructions "BOLD" is just an example of what I want to do but I always get an error beacause of ambiguous column.
  
  Thanks to advnce. :)

  Not valid. This makes no sense and breaks all the rules of scope-resolution. And if it is in a single database, or uses tables in databases, is not relevant.

  Each object must be particularly well identified. If you cannot do this:

  select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a
  

  3 objects cannot share the same alias. Example:

  SQL> select * from (dual, dual) d;
  select * from (dual, dual) d
                     *
  ERROR at line 1:
  ORA-00907: missing right parenthesis
  

  You need to combine objects - by using a join union or similar. He will have to be done as follows:

  SQL> select * from (select * from dual d1, dual d2) d;
  select * from (select * from dual d1, dual d2) d
         *
  ERROR at line 1:
  ORA-00918: column ambiguously defined
  

  However, we need to have unique column in a projection of SQL names - so the join of the need to project a unique set of columns. So:

  SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
  
  DUM DUM
  --- ---
  X   X
  
  SQL> 
  

  I suggest that you look carefully at what opportunities are and how it applies in SQL - and ignore if the referenced objects are local or remote, because it has no effect on the basic principles of scope-resolution.

• 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

  Mike

  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

  FROM MyTable;

• Additional column names selected when you use the describe "popup" to select columns

  Hello

  In SQL Developer 3.2.20.09, if you use the popup describe the function on a individual table columns using Ctrl + click (not shift click choosing a range of columns) and select and then drag them to the SQL worksheet to find the column names, it includes all of the columns between the individual columns that have been selected.

  For example if I choose column 1 and 5, it includes 1,2,3,4,5 columns when I drag them through.

  Simple to reproduce on any table, just open the SQL worksheet, type the name of a table, open the popup describe and select some columns.

  Kind regards

  Hi all

  As well stressed Centinul this approach is prone to sql injection.
  Usage of DBMS_ASSERT function. SIMPLE_SQL_NAME can avoid this problem, but there are onliy on Oracle 10.2 and later.

• 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.
  
  I tried:
  
  Select distinct: P133_COLUMN d: P133_COLUMN r
  FROM MyTable
  
  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...
  
  If I change
  
  Select distinct P133_COLUMN d & P133_COLUMN r
  FROM MyTable
  
  I get the standard
  "LOV query is not valid, a display and a return value is needed, the column names must be different. If your query contains a query online, the first CLAUSE in the SQL statement must not belong to the query online. »
  
  Anyone?
  
  Also, I was wondering if it is possible to set the textfield object in the item popup LOV to accept the input text directly as well as the selected value, but the first part of the question is the important part.
  
  Concerning

  Hello Andy,

  Change your LOV to something like this:
  'select' return. : P133_COLUMN |' d, ' | : P133_COLUMN | "as r from myTable";

• Using PL/SQL to retrieve column names and column values

  If I have a table as follows

  and the table contains a row

  Is it possible in pl/sql to retrieve the names of columns and values. I have an object type
  (OBJECT) ACE DATA_DEFINITION_T
  VARCHAR2 (32) 'FIELD_NAME ',.
  'FIELD_VALUE' VARCHAR2 (32)
  
  I need to store the column name in field_name and the value of column in field_value.
  
  So, the result would be:
  
  Field_name = meals
  Field_value = pork_chops
  
  Field_name = drink
  Field_value = iced tea
  
  Field_name = desert
  Field_value = croustade
  
  Thanks in advance.

  The Subscriber to the queue will pick up the message and how to process the data (field_value) based on the field_name (s). With the domain name, it cannot be what to do with the data.

  Sounds like an XML approach would be better than this owner = value field.
