Query by query column names

• Dependent on the value of query column names

  Hi guys, I don't think this is possible, but I thought I'd give it a go.
  
  I am wanting to values that are returned by my query as column headings. For example:
  
  SELECT 1,2,3,4,5
  OF trade_table
  WHERE < 6
  
  The table contains 10 records, "A1", "B1", "C1", "D1", "E1", "F1" etc... and my query returns 5 records of each with a rating of 1 to 5. The first record in the standings, lets say "D1" must be the column heading.
  
  I'm extremely sorry for being vague, but my request first contains a lot of analytical functions and I try to simplify it.
  
  Thanks in advance.

  To do this with the reporting you tool use and not with SQL and PL/SQL.

• 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;

• 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

• Anyway, to remove the column names in the result of the query of SQLPLUS

  Hello
  
  I am using sqlplus to run a script that returns results with the column names.

  Comparing the old and new values wud tell me which column is updated then how to get the anme of column

  for example update test set emp_name = "Sicard' where emp_pos = 'President ';

  now I want to insert 'emp_name' in the table test_hist as follows

  name colmn = old value = new value = update the = updated by
  emp_test = notsapan = sapan = sysdate = syscontext_user

  Well, since you have a typical requirement (for which Oracle doesn't have a built-in support), you will need to compare the old and new values, and insert the name of the column "manually" in the logging table.

  Little extra processing is indeed (CPU cycles) to find the modified column.

• Having a column name as a variable in a query, problem!

  I have a problem with a simple query below
  
  
  SELECT * FROM DisneyWHERE Upper (COLNAME) AS SUPERIOR ('%' |) SEARCHSTRING. '%'); SELECT * FROM Disney
  WHERE Upper (COLNAME) AS SUPERIOR ('%' |) SEARCHSTRING. '%');
  
  My problem, the variable of column name is not recognized as a column for example name
  A user can select to display a set of characters from the database by user name, movies, etc (they selecting this function since a combobox), they then enter a search string (textbox)
  column name = user name
  SearchString = pluto
  
  SELECT * FROM Disney
  WHERE Upper (COLNAME) AS SUPERIOR ('%' |) SEARCHSTRING. '%');
  
  The problem is orac; e does not seem to be picking up this column name is a column name and seems to be a simple comparison. To make this more clear
  
  It "seems to match the username = pluto
  instead of find pluto in the username column.
  
  Someone at - it ideas how I can get around this. I have a strange feeling, it's something to do with pl/sql dynamic, but I am new to oracle, so I have no idea of how to write dynamic queries. Any help would be appreciated muchly

  Sort of Yes and no.

  If colname is 'film' and the search string 'star wars' is the place where actually takes the clause...

  WHERE username as username
  AND the movie like 'star wars % % '.

  If username is not limited in any way and it limits just on film.

  Conversely if the column name is "username" and the search string is 'Bob Smith' then where clause evaluates actually to...

  WHERE username like ' %% of Bob Smith.
  AND the film as film

  then move is not limited in any way and simply limits on the user name.

• fix column names in a sql Query

  Hi people,
  
  I am upgrading an application and there are database columns that have major changes that could affect the production of reports. I want to the investigation from v$ SQL for a few days to see if these columns are affected. That is the problem.
  
  Watching a SQL query to determine which columns are used is not nearly as easy as it sounds. Are there functions oracle or 3rd party tools that allows to display the columns used by a sql query? (this becomes extremely difficult when subqueries are involved)
  
  For example.
  
  Select
  
  name, b.dep_id, employe_id
  EMP a
  Inner join v_department b on a.dep_id = b.dep_id
  
  Used columns:+.
  EMP. Name+.
  Departments.dep_id (under the view).
  EMP.employee_id+.
  EMP.dep_id (from the join)+.

• Invalid or missing query column.

  If anyone knows why I get this error?
  You must specify the name of a column in the query "nameoflists" for the attribute Value of the CFSelect tag.
  
  I just want to show PBT_LISTNAME inside my selection box.
  
  < cfquery name = "nameoflists" datasource = "webbs" >
  SELECT DISTINCT PBT_LISTNAME
  OF PBT_BILLS
  WHERE (PBT_USERNAME = ' #form.) PBT_USERNAME #')
  Order by PBT_LISTNAME
  < / cfquery >
  
  < cfoutput >
  < cfform action = "pers_bill_hist.cfm" >
  < cfselect query = "nameoflists" name = "list" size = "1" >
  < option value = "#PBT_LISTNAME #" > #PBT_LISTNAME #.
  < / cfselect >
  < / cfform >
  < / cfoutput >

  When you use the query of the , it's going to tag option
  build your tags option automatically for you. To do this, he wants that you
  to tell which column in the query to use for the option values.

  
  #PBT_LISTNAME #.

  You can also use the display property to indicate which column
  to use for the displayed option.

• How to map Dynamic Query columns on variables of forms.

  Dear all,
  This is a correct code for executing a dynamic query and display data.
  In this program that I have defined variables ("BOLD" of police) later I binds these with the query (in the second code "BOLD").
  
  How I can map a column in the query, in which case I don't know that the surveyed fields type?
  
  
  
  GetData PROCEDURE IS

  If you want to use EXEC_SQL and a dynamic query with unknown data types, but the known table name,
  Then you can declare a rowtype variable
  for example;

   NOT TESTED ---A ROUGH IDEA
  m_emp_row employee_master%rowtype;
  m_col_cnt number := 0;
  So when you define collumn, create a procedure to find the column name and its width if it is varchar2 with respect to the column name .

  ---------------------------------------------------------------------------------------------------------------------------------------------------
    while m_col_cnt < 3 loop

  ---------------------------------------------------------------------------------------------------------------------------------------------------
  --Your procedure will look like this

• TDM file query property names

  I use the TDM files to save data from the trial.  At the file level, I am inserting a number of custom property labels (using the Property.vi defined in the IO file-> storage-> advanced storage pallet).

  Is it possible to query the names of these properties once the file has been written?  For example, if I put in a custom property "TestLocation", is there a way I can find the name of this property afterwards, so I can read the value?

  JoeG

  Hey Joe,

  Please try the attached VI for the names of the custom properties.

  Best regards

  How to get those details using sql querry.

  SELECT column_name

  Of all_tab_cols

  WHERE table_name = 'name of the Table.

  or

  SELECT column_name

  Of all_tab_cols

  WHERE table_name = 'name of the Table.

  AND owner = 'name of the owner.

• 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 ,

  COUNTY (*) Total

  DE DOCUMENT_TABLE

  OUTPUT:

  Zero

  One

  Two

  Three

  Four

  Five

  More than five

  Total

  3

  6

  3

  6

  10

  50

  100

  178

  Now the desired output:

  The column name must be the date, for example the column name, we're Sysdate, two column name is Sysdate-1 day and the result would look like:

  OUTPUT:

  17/12/2014

  16/12/2014

  15/12/2014

  14/12/2014

  13/12/2014

  12/12/2014

  More than five

  Total

  3

  Hi, just try below as you say it's urgent

  Select sysdate, sysdate-1, sysdate-2, sysdate-3,-4, etc of daul sysdate

  Union

  your query

  (you must ensure for the same type of data)

  are you using oracle report or just in the sql query. If the reports, then you can manage very easily with the introduction of a formula column.

• 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

  , a. *-If wanted

  Of abc123 one
