• Understand the joins with more than one column?

  Hi all

  I want to know if I understand.

  When you join two tables, and the join condition has four columns (two for each table) as follows:

  where d.deptno = e.deptno

  and d.name = e.name

  I think it means the engine must choose "the selection list" when he sees a number of d.deptno (for example 10) equal number in e.deptno, and

  the d.name from the same folder (10) must be equal to the value of e.name.

  I understand?

  Another example, I want to understand, when we say:

  where d.deptno = e.deptno

  and d.deptno = s.deptno

  This means that the number (10) should for example equal to one (10) in the table (e), and the same 10 must be equal to a value in the table (s)?

  Am I wrong?

  Thank you

  Hello

  Yes, what you say is right; but don't take my word for it.  Try it yourself.   Create a couple of small tables.  Insert some data that matches (and will appear in the results of joints) and others that does not (and should not be in the results) and see if the results are what you expected.

  Hello

  Welcome to the forum!

  As Centinul said, it's called swivel and the Centinul post link has several good pages.

  Something crucial about swing is that before you do rotate, you know, look at each line of no cross-data Dynamics, rows and columns will be affected by this line. For example, looking at the line with id_dep = 2 and id_val = 'G', how can tell you where (what row and column) who will go 'G '? id_dep uniquely identifies the line, but there is nothing in the table that indicates if the 'G' will end up in the 1st column crosstab, or 2nd or 3rd, or... Before you can rotate the data, you must generate a number for yourself.

  Since I don't have a copy of your table, I'll use the table scott.emp to illustrate. Say we want to list the employees in each Department, in alphabetical order, like this:

  `   DEPTNO NAME1      NAME2      NAME3      NAME4
  ---------- ---------- ---------- ---------- ----------
          10 CLARK      KING       MILLER
          20 ADAMS      FORD       JONES      SCOTT
          30 ALLEN      BLAKE      JAMES      MARTIN
  

  Deptno column (like you id_dep) is all we need to know about what an exit row corresponds to each input line, but we must build something which says "CLARK" will go in the same column as "ADAMS" and "ALLEN". This soemthing is in this case, the ROW_NUMBER analytic function:

  WITH     got_r_num     AS
  (
       SELECT     deptno, ename
       ,     ROW_NUMBER () OVER ( PARTITION BY  deptno
                                 ORDER BY          ename
                         )         AS r_num
       FROM    scott.emp
  --     WHERE     ...     -- If you need any filtering, this is where it goes
  )
  SELECT       deptno
  ,       MIN (CASE WHEN r_num = 1 THEN ename END)     AS name1
  ,       MIN (CASE WHEN r_num = 2 THEN ename END)     AS name2
  ,       MIN (CASE WHEN r_num = 3 THEN ename END)     AS name3
  ,       MIN (CASE WHEN r_num = 4 THEN ename END)     AS name4
  FROM       got_r_num
  GROUP BY  deptno
  ;
  

  Thanks for posting your version number; It's always good to do whenever you have a question. Sometimes the difference between Oracle 10.1 and 10.2 can be important. It is best if you post your full version, for example 10.2.0.4.0.
  The query above works in Oracle 9 and 10. Of course, it will not work in higher versions, too, but if you have Oracle 11 then you would like to use the SELECT new... PIVOT functionality, instead.

• End of the file has detected the error for more than one column of a PDM file playback

  Hello fans of LabVIEW,.

  I write the data in several columns of a PDM file. After that, I would like to read the data in each column to treat it.

  writing data works without any problem, if I get a PDM file with say 4 columns of data. When I try to read these columns now, LabVIEW always gives me error 4 "end of file" for all but a PDM read functions. Regardless of the number of columns I've read or how big they are, its still the same. LabVIEW reads a column and gives the error for all other tdms read functions.

  Does anyone has an idea how to solve this problem?

• I can't have more than one value of function?

  I hope all of you can point me to some introductory articles/documents on function.

  I know the function is used to calculate a value and it always returns a single value.

  I want to know I can get more than one value of function? If so please share a few lines of code

  Hello

  Certainly, you CAN define functions with OUT parameters. It is generally not advisable to do so, however. Working with settings, for example, can be called from SQL, among other useful things.

  If you are wanting a function that returns multiple values, you would generally be

  -create a procedure that has several OUT parameters

  -create a function that returns a type of object that encapsulates the values that you want to return

• If having more than one plan - sql_id can check?

  Hello everyone;

  If sql_id with more that one plan - can check?

  Oracle documentation

  A SQL statement can have multiple plans in the shared pool.

  Each plan has a different hash value. If the same ID SQL_ has several plan hash values,

  the database knows that several plans exist for this SQL ID.

  
  

  WHAT a way to find, what sql_id having more than one plan?

  HR > select * from table (dbms_xplan.display_awr (& sqlid));

  Enter the value of sqlid: 7wj456mbwr2gu

  old 1: select * from table (dbms_xplan.display_awr (& sqlid))

  new 1: select * from table (dbms_xplan.display_awr (7wj456mbwr2gu))

  Select * from table (dbms_xplan.display_awr (7wj456mbwr2gu))

  *

  ERROR on line 1:

  ORA-00907: lack of right parenthesis

  Whatever i change, even still getting error.

  > If sql_id having more than one plan - can check?

  How would know you if any value of the column in any table there are more than once?

  > select * from table (dbms_xplan.display_awr (7wj456mbwr2gu))

  SQL_ID is a string of characters.  As such, it must be in quotation marks.

• I have to remove the duplicate files, but having problems by selecting more than one file in the player at the time.

  I have to remove the duplicate files, but having problems by selecting more than one file in the player at the time. How can I select multiple files at the same time so I can just delete them. I used to be able to do this in previous versions of Media Player, but this function seems now blocked or unavailable. The problem is this: through previous use of media player, it plays all my multimedia files several times whenever a device support has been added. He would try to save the files on my main drive, but since there is not enough room this would save the files somewhere else. This happened several times, I suppose, because when I upgraded my computer and a media scan was conducted he found duplicates of all my media various times of at least 6-8. I've consolidated since my plates on 3-disc multi to, but have now records duplicated hundreds and thousands of duplicate media files. Previous versions of Media Player would allow me to select all files and then delete them both of the reader, but also from my hard drive. So now I'm stuck with more than 300 GB of duplicate media I have to search line by line through all my hard drives to find each duplicate both, unless I can get media player to do what it can. Any help in this area would be appreciated.

  Hello

  1. did you of recent changes on the computer?

  2. is Windows media player files in double creation during playback of music files?

  To delete duplicate entries, click on another feature tab in the drive (for example the current playback), and then click library.
  
  If this does not remove duplicates from your library, you can use the Add to library dialog box to search computer to analyze a file on your computer the duplicate entries not valid-pointing. The player will remove invalid entries in your library that point to files that no longer exist in the folder.

  Complete the steps above for files that are stored in the hard disks.

  Method 1: Use the add to Library dialog box search for computers

  (a) start Windows Media Player.
  
  (b) press F3 on your keyboard to open Add to the library of the find computers dialog box.

  (c) click the Browse button to locate the folder on your computer so that your library contains invalid entries. Specify the location of the folder in the box look in.

  If you are not sure what duplicate in your library entry is not valid, you can add a path column to display in your library. Specify the folder on your computer that corresponds to the path not valid file displayed in your library.
  
  (d) click on the Search button.

  The player will search for digital media files and playlists in the folder that you specify and remove invalid entries in your library that point to files that no longer exist in the folder. If not valid in double entries point to other folders on your computer, repeat this procedure, specify a different folder every time.

  If only a small number of duplicate entries exist, you can delete those invalid manually by right-clicking on the invalid entry, and then clicking Delete .
  
  For large double-number of entries in your library (or if all your library is duplicated), it might be better to create a new library and delete the files.

  Method 2:

  After you remove the duplicate entries, run the troubleshooting of Windows Media Library settings to solve this problem.

  Open the troubleshooter in Windows Media Library

  http://Windows.Microsoft.com/en-us/Windows7/open-the-Windows-Media-Player-library-Troubleshooter

  Let us know the results.

  I hope this helps.

• How to create an entity with more than one primary key.

  Hello

  JDeveloper Version 11.1.2.4.0

  I am trying to create an entity object based on a table with 5 columns. The combination of them is unique.

  I do the five columns of primary keys, but when I delete a line I: RowAlreadyDeletedException, although always the line exists in the database.

  Also displaying the view sometimes I get Houston-25019: line entity oracle.jbo.Key [1 key 2 null null NULL].

  
  

  
  

  How to create an entity based on one object several columns in the primary key?

  I don't want to add an additional column to a primary key, because this table is used in many PL/SQL procedures, and I'm not sure that this will not affect the.
  

  Also using Rowid as a primary key should be avoided.

  Kind regards

  Pamela.

  As I said, the framework is not like that

  Check this old (but still relevant) blog of Sung Im on Table Whose Primary Key entity object can be NULL

  describing the reason behind the behavior you're seeing and the way around.

  Or you use the secondary key rather as described here Wael Abdeen Blog, how to look at the views - part 2 | Oracle ADF as a secondary key composed of more then one column can have null values.

  a unique constraint is simply "at any time, these values are unique - they can change and they can be null.

  You use a unique when constraint

  (a) you do not already have a primary key for a table can have only one
  (b) you allow NULL values in attributes
