  Hello

  So, instead of having 2 columns on 1 row, you want to have 1 column on 2 rows.  It's just that UNPIVOT:

  SELECT DISTINCT

  ID, num

  D

  UNPIVOT (num

  FOR the label IN (num1, num2)

  )

  ORDER BY id, num

  ;

  It is more effective than the UNION, because it requires only 1 pass through the table.

• I need to return the result of a query on a stored procedure

  I need to return the result of a query to a stored procedure, I mean when I run a stored procedure it returns a result set in a select statement.
  Best regards...

  Hello.

  Do you really want a stored procedure for this?
  Why not just a script that contains the query?

  Assuming that you don't really want a stored procedure, you'll have to decide what to do with the results.
  An option is a slider.

  For example, you can write a procedure of this type to hold the query:

  CREATE OR REPLACE PROCEDURE USP_TEST
  (     out_cursor     OUT     SYS_REFCURSOR
  )
  IS
  BEGIN
       OPEN  out_cursor
       FOR     SELECT     *
            FROM     scott.emp;
  END  USP_TEST;
  /
  SHOW ERRORS
  

  You can move the cursor to another procedure for handling.

  You could test this in SQL * more by creating a variable blond:

  VARIABLE     usp_test_cursor     REFCURSOR;
  
  EXEC  usp_test (:usp_test_cursor);
  
  PRINT     :usp_test_cursor
  

• Ask... How to reach the result sets in order?

  Let me give a few examples of data first to give an idea of what I am working with:
  
  Oracle: 10g
  

  --Table xTable
  
  NAME             DESC_ID
  ALAN                   2 
  AMY                    3
  BILL                    5
  BOB                     7
  CARL                   1
  CHRIS                  8
  DAN                    4
  DEREK                 6  

  So what I try to do is right out of names (ALAN, CHRIS, DAN) in ascending order (according to out of name) and then all the names (AMY, BILL, BOB, CARL, DEREK) in ascending order (according to out name)... and I want all of this in a single result set. So basically the first set of names in alphabetical order, followed by the rest of the names in alphabetical order.
  
  I want the output to look exactly like this:

  NAME       DESC_ID     
  ALAN               2
  CHRIS                8
  DAN                  4
  AMY                  3
  BILL                   5
  BOB                    7  
  CARL                  1
  DEREK                6  

  I tried the following, but it doesn't seem to work
  

  select distinct a.name, a.desc_id
  from xTable,
  (select distinct name, desc_id
  from xTable
  where DESC_ID  in (2,8,4)
  order by name
  ) type1,
  (select distinct name, desc_id
  from xTable
  where DESC_ID  in (1,3,5,6,7)
  order by name
  ) type2
  where desc_id in (type1, type2);

  The code above seems terribley unefficent and apparently not at the exit of the things in the order I want. Any ideas?

  If you have a known list of DESC_ID you could do something like this:

  SQL> WITH xTable AS
    2  (
    3          SELECT 'ALAN'   AS NAME, 1 AS TYPE_ID, 2 AS DESC_ID FROM DUAL UNION ALL

    6          SELECT 'BOB'    AS NAME, 2 AS TYPE_ID, 7 AS DESC_ID FROM DUAL UNION ALL

• Need to print the results of a query in a CASE statement

  I want to print the results of a query in a CASE statement:

  SELECT RUN_STATUS

  Of

  (select check BOX WHEN COUNT (ROW_WID) = 0 THEN 'NO JOBS RAN AFTER' |) (select sysdate - XXAFL_MINUTES MINUTE)

  END RUN_STATUS

  of W_ETL_RUN_SDTL

  where START_TS >

  (sélectionnez sysdate-MINUTES de XXAFL_MINUTES)) where RUN_STATUS is not null; e

  The query above subtracted 5 minutes from SYSDATE and he shoots XXAFL_MINUTES. I am doing this because we could change the number of minutes in the future. I want to print the number of minutes in the case statement.

  If I execute this statement, it throws an error stating:

  ORA-00937: not a single group group function

  00937 00000 - 'not a single-group function.

  * Cause:

  * Action:

  Error on line: 1 column: 96

  How can I include "select sysdate - MINUTES of XXAFL_MINUTES" in the CASE that it calculates the number of minutes and it prints with the results.

  Thanks in advance!

  Hey guys,.

  I found the solution:

  SELECT

  RUN_STATUS | TO_CHAR ((sélectionnez sysdate-MINUTES de XXAFL_MINUTES), 'HH24:MI:SS')

  Of

  (select check BOX WHEN COUNT (ROW_WID) = 0

  THEN "NO JOB RAN.

  END RUN_STATUS

  of W_ETL_RUN_SDTL

  where

  START_TS > (select sysdate - XXAFL_MINUTES MINUTE))

  where

  RUN_STATUS is not null;

  The output:

  NO JOBS RAN AFTER 09:07:54

  Thanks to you all!

• Need help understanding the results of security analysis.

  My agency has recently started using tool to fortify scanner of HP, which aims to analyze the code of the CF directly, rather than the rendered page.  The scanner always seems to mark our pages for some error when I use the following code (used to create a PDF file on the fly):

  <cfheader name="Content-Disposition" value="attachment;filename=#pdffile#">
  <cfcontent type="application/octet-stream" file="#expandPath('.')#\#pdffile#" deletefile="Yes">
  

  01. is line 299 in my code.

  I'm basically generates a name of file elsewhere on the page that is based on what a user is requested, then using the code above to create a downloadable PDF of this file.

  The error is:

  Manipulation of the header (validating input and representation, stream)

  The myfile.cfm file includes data not validated in a 299 online HTTP response header.  This allows attacks such as the poisoning of the cache, cross-site scripting, cross-user daub, hijacking the page, cookie or open redirect handling.

  I think it is one of two potential problems.

  1. ExpandPath() is exploitable
  2. The scanner is programmed to any variable passed to a Pavilion cfheader tag.

  Any thoughts?

  You need to scope the variable pdffile.  Without a specific scope, it could be overwritten by URL or form variables entrants.  I would try that and then re-run the analysis.

  Well, when I run a query through TOAD, SQL or SQL Developer *, it results the first time.

• Need to query the result with two different of a same attribute values

  Hi all
  
  I have a search query where I need the query result when an attribute have two different values (e.g.: want the query result when the attribute 'status' is equal to 1 and 2)
  
  And also, the user will be able to search by any State result.
  
  What is the best way to implement this.
  
  Thank you
  DK

  The solution to this use case is to put the part by default ((statut == 1 ou statut == 2) and: bindUserInput is null) as part of the query and the Pratt of the query to run when a value is entered by the user in a view criteria. East view criteria (Status ==: bindUserInput) and the value of the checkbox to ignore the values null. If the binding variable: bindUserInput is null, only the portion of the query is running, if the binding variable is not null, the display criteria is added at the request of three and three default components will not return any line.

• Pavilion Elite HPE-170 t: need help with the result of a command prompt to Power Options

  I have recently upgraded to Windows 10 in Windows 7.  Like so many thousands of people, I problelms of sleep mode.  Mine will not be auto-sleep.  It has been suggested that I saw to run command prompt: powercfg-applications

  It supposedly will list the items running on your computer which can now be auto-sleep to work.  I tried several times and up to now, I get the same item displayed each time.  This is what is displayed: \device\harddiskvolume2\windows\sysWOW64\svchost.exe (hpqddsvc) is followed by this message: a file delete operation is underway

  My first thought is that if there is an operation to remove file in progress all the time, it's maybe the reason why my computer is not auto-sleep.  If there is someone out there who can shed some light on this situation, I would appreciate the help.

  EUREKA * SOLVED
  

  I found the answer to my problem!  After using the control system: powercfg-query and get the answer: \device\harddiskvolume2\windows\sysWOW64\svchost.exe (hpqddsvc) delete file operation is in progress

  I started looking for whatever it is associated with the answer above.  In the Manager of tasks in respect of the services, I found the name of the file hpqddsvc, with a description of HP CUE DeviceDiscovery Service was running.  When I stopped the task and re-tried in opt power standby mode, it worked correctly.  In the Configuration of the system (by typing msconfig at the run prompt) on the Services tab, I unchecked the box for HP CUE DeviceDiscovery Service and rebooted the computer.  The service is no longer running.

  I'm sure that this Service has been added to my computer when I downloaded the hp.com/support product detection tool .  The tool scans your computer to detect and identify HP products.

  This can be useful to others who have the problem of the auto-sleep I've had.

• How to display the results of the database from several tables in descending order?

  I have a key word to search for images on my website that allows visitors to search for specific things. My db msysql has 15 tables and for the search function I use a UNION ALL operation to join them any visitor can find all tables at the same time. The problem is that all the results are in ascending order. How can I get the results in descending order.

  SELECT *.

  FROM table1

  Keyword WHERE AS id LIKE %s or %s

  UNION ALL

  SELECT *.

  FROM table2

  Keyword WHERE AS id LIKE %s or %s

  UNION ALL

  SELECT *.

  TABLE 3

  Keyword WHERE AS id LIKE %s or %s

  PS

  I tried this and it doesn't work:

  SELECT * FROM table1 WHERE AS %s or id AS %s ORDER BY id DESC keyword

  and I know that this is not conventional to use SELECT * with so many tables, but believe me, I have my reasons. I'm not trying to do is to wrap the whole UNION within an external SELECTION

  Once more, the order by clause can only appear at the end of the last select statement in a UNION query. You have it on all select statements.

  If the user makes a search with "MADONNA", I view the results as title begins with "MADONNA" first then the rest of the records.
  Please let me know is possible to show the results in this order.

  This can be a little more specific:

• Procedure to export the result of the query to an excel or csv

  Hi all

  I have two identical paintings

  EMP_TEST OF THE EMP

  ID ID NAME

  1     SAM                      1        SAM

  2 JOHN 2 ROCK

  3 3 STEVE BRAND

  I need to combine the result under the query and intent to export data to excel using a procedure

  my query is

  Select 'EMP_ID', E1. EMP_ID, AND. EMP_ID from emp E1,

  emp_test AND WHERE E1. EMP_ID = AND. EMP_ID

  UNION

  Select "EMP_NAME", E1. EMP_NAME, AND. Emp E1 EMP_NAME,

  emp_test AND WHERE E1. EMP_ID = AND. EMP_ID

  but I get this error message

  ORA-01790: expression must have same type of corresponding data

  EMP_ID is a number and EMP_NAME is of type varchar.

  I need any idea or suggestion on sub queries.

  (1) I have to combine the result set in a single query.

  (2) I need to write the procedure that will export the result of the query to an excel or csv.

  Thank you.

  As PR has said, there are ways that have already been explained in this forum to write in external files. For your query condition, try this.

  SELECT CASE WHEN (REGEXP_LIKE (T1.ID,'[^ [: alpha:]] "")) THEN 'EMP_ID '.

  ELSE "EMP_NAME' END AS COL_NAME.

  T1.ID,

  T2.ID

  DE)

  SELECT CASE WHEN ID IS NULL THEN NAME ANOTHER TO_CHAR (ID) END AS ID,

  ROW_NUMBER () OVER(ORDER BY RN NULLS FIRST,ID) RN

  DE)

  SELECT ID, NULL,

  NAME,

  RN ID

  FROM EMP

  UNION ALL

  SELECT ID,

  NAME,

  RN NULL

  FROM EMP)) T1.

  (SELECT CASE WHEN ID IS NULL THEN NAME ANOTHER TO_CHAR (ID) END AS ID,)

  ROW_NUMBER () OVER(ORDER BY RN NULLS FIRST,ID) RN

  DE)

  SELECT ID, NULL,

  NAME,

  RN ID

  OF EMP_TEST

  UNION ALL

  SELECT ID,

  NAME,

  RN NULL

  OF EMP_TEST)) T2

  WHERE T1. RN = T2. RN;

  OUTPUT:

  COLUMN-NAME ID ID
  --------  ---------------
  1 1 EMP_ID
  2 2 EMP_ID
  3 3 EMP_ID
  SAM EMP_NAME MARK
  EMP_NAME JOHN JOHN
  EMP_NAME STEVE DARREN
