ORA-02260: table can have only one primary key

• "A project can have only one temporal signature... '. ' Really?

  I find it very difficult to believe that Garageband requires this ridiculous limitation.  Am I missing something?  If this is not the case, the application is only a toy, musically speaking.  Compositions have systematically signature rhythmic changes!

  It is unfortunately true.  You can change the tempo or key of a song between different measure, but not the time signature.  You must upgrade to Apple professional DAW Logic Pro X, if you want to change the time signature or other advanced features.

  I use workaround to record the parts of the song that needs different signatures of time in separate projects and then combine the songs bounced into one.

• Why we cannot create more than one primary key on a table. Why we create several unique key on a table. Please explain if anyone have details of this.

  Why we cannot create more than one primary key on a table. Why we create several unique key on a table. Please explain if anyone have details of this.

  «a primary key has semantic meaning, it is to be immutable (never change of value), unique and not null.»

  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
  "(c) to allow you to update the values in the attributes.

• LOV cascading if I don't have only one table with the customer name and the name of the product in the ADF.

  Hi Please help me how to use cascade, if I don't have only one table with the customer name and the name of the product in the ADF... I use Jdeveloper 11.1.

  For the client, I used customer VO with client list to fill but to populate the product that I use bind variable PrODUCT_NAME select distinct from TABLE where client_name =: bindCustomer

  so first of all, I need to set the variable of liaison on behalf of the selected customer.

  Can you please tell me how to set this variable binding in this case.

  After you set the LOV to your product attribute, correspondting VO in the LOV will appear under view accessors.

  Change the accessor of the view, you will see the variable binding. Set its value to the customer field of the parent object.

• Limit the number of partitions of a table can have

  Hello
  
  It has been a while I think about a simple method and the best solution to a performance problem in my application. Benefiting from the table partitioning seems a simpler approach. It involves tiny my application code changes and more, it keeps the logic of global application 100% intact. However, sometimes the number of required partitions can grow to more than 500 thousand. I know another application implementation of partitions that 50 thousand for one of his paintings. I wonder if Oracle recommends or puts a limit to a number of partitions of the table can have. How does that limit, if it exists, varies so each of my partition table contains only a small amount of data. say, no more than 2 thousand records each of size 1 KB. What are the important considerations to keep in mind while creating the huge number of partitions of a table?
  
  All entries on this would be a great help.
  
  
  Thank you

• Add the same touch to three cans but only one gets the button

  Hi all

  I have these containers three pennies for my app and a button that I would add to all three of them.

  So I created the button

  totalParallal = new LabelButton();
              totalParallal.addEventListener(MouseEvent.CLICK, calculateParallal);  
  
              RightSub.addChild(totalParallal);
  

  added to a subcontainer, but when I tried to add another container (MidSub)

  MidSub.addChild(totalParallal)
  

  the button appears in my container MidSub, not the RightSub. Can someone explain to me why this is? All this is done in the function InitializeUI.

  Hey jzou,

  in AS3, all child objects can have only a single object parent. which means that the last place you add an object as a child, the new parent is the object that calls the addChild() method. important if the number of objects summon the addChild() on a single instance method, the last object that called the method will be the child object to himself.

  wats that past in your code is the MidSub container is the last caller of the of the object that you are adding, and consequently addChild() method, the final parent. you will need to create new instances of object to add it in several places. hope that things cleared up. Good luck!

• Toshiba Bluetooth stack & motorcycle S805 two profiles - can use only one?

  Toshiba Bluetooth stack on IBM T42/Windows 2000 test. Motorola S805/multimedia headset supports two audio A2DP stereo of high quality and HFP used as a helmet.

  If I create * only * audio sink profile then I can log in and use the headphones (rather good sound!). If I create * only * a headset profile, then they work well for that, too (not very good sound, but convenient and two-way).

  I am able to create two connection profiles by linking it first as an Audio receiver, then the pairing again as a helmet. The two profiles now appear in the Bluetooth settings window. First of all, I confirm that neither the profile is connected. Now when I try to 'connect' to the headset, it "sounds" the helmet. However, when I press the headset button to accept the connection I get the following message:
  "Now, connect, please wait."
  and then
  "Helmets and headphones can not be used simultaneously. Finished using the headphones and then establish a connection.
  Now the headset (audio receiver) is connected instead of the helmet!

  Note that before I tried to connect to the headset there was no link at all (message is wrong). Also note that if there is only one connection profile (headset) then the headset will connect correctly.

  I want to be able to move quickly from a helmet (good sound quality for music) and headset (for Skype). Deletion and recreation of the connections are too slow, if Skype sounds while I'm listening to music. (the S805 will automatically switch mode headphones while listening to the music, if the call is from a third device such as a cell phone).

  Anyone know if the software can be configured to allow me to do this fast switching between profiles on the same device?

  Thank you and best regards,

  Jeff in Aloha, OR, USA.

  You must use the hands-free profile if it is supported also by your device for VoIP instead of the headset profile!

• I don't have a single drive hard, but pc says I have c and d ' training is posible to bolt to merge and have only one

  I can't update windows xp drive c doesn't say not enough free space do not understand how I c and d when I have only a hard drive

  This article (KB187876) is a little dated.  The suggestion to convert to FAT32 FAT16 is!  And references to Scandisk and DriveSpace3 reveal even that the article was probably written with Win 98 in mind.

  I realize that the article header says "Last Review: February 3, 2011 - review: 4.1", but without doubt, Microsoft should have removed this article or at least Windows 95, Windows 98, and Windows Me added to the list of "products of this article applies to" rather than leave it just to "Windows Update" (which makes it sound as if it applies to current versions of Windows).

  To the original poster:

  If D: is on your hard drive (instead of referring to a CD player), TechGeek2 is probably right that there is a restore partition and should be left alone.  Here is my answer to the question of the "low disk space": canned

  There are a number of things you can do to- temporarily - free up disk space.  The only real solution, however, is to get a bigger internal hard drive or internal a second drive.   You can move the data to an external drive, but if it's the data that you use frequently, slower access times may annoy you.  Therefore, I do not recommend that you move your My Documents folder in its entirety on an external drive, but you can certainly do this by following the related instructions. Moving My Documents to a second internal drive would be OK.

  • You can run Disk Cleanup (start > run > cleanmgr > OK)
  • You can reduce the size allocated for the restoration of the system to about 1 GB (right click on desktop > properties > system restore > settings)
  • You can disable hibernation (if you don't use it) (right click on an empty spot on the desktop > properties > screen saver > power > Hibernate)
  • You can disable the indexing of the drive, which will also speed up your computer a bit (http://lifehacker.com/031440/turn-off-indexing-and-speed-up-windows-xp)
  • You can reduce the size of your Internet browser cache (depending on the browser that you use)
  • You can remove most of the $NTUninstallKBxxxxxx files $ following the directions here: http://windowsxp.mvps.org/Hotfix_backup.htm (read the warnings in the gray box first)
  • See also:

  " How to recover disk space on Windows Server 2008 and Windows XP computers? ."

  " Forty ways to free disk space ."

  But none of these answers you will earn really large amounts of space for very long.  The term solution time is a bigger hard drive.

  In the meantime, download and run JDiskReport, that will show you graphically what files take up more space and seem to so indicate what files you must move it to your external drive.  If you want to move an application to another drive (external drive or secondary internal drive), you will need to uninstall and then reinstall it specifying the other drive as the installation location.  You can not simply move the files.  Even when an application is installed on a different drive, however, it may well put some files on the system drive (i.e. the drive where Windows is located).

• Make required error appears only the primary key generated in prior Database Table insert trigger

  Dear all,

  I am a beginner in the ADF and am under Jdeveloper Studio Edition Version 12.2.1.0.0.

  
  

  I'm trying to insert a record, I created the trigger for insertion prior to get the primary key and set some other default values.

  
  

  On the page, I did read-only primary key column and false required.

  
  

  When I try to save - commit (Programmatic), I get errors for the required value. How can I stop this errors.

  
  

  Secondly, I also tried changing the agent to disabled on the attribute View object that raised the error below:

  If the primary key values from DB sequence, you can follow this approach:

  Using the sequence of database in ADF - Souza Waslley Blog

  Oracle Fusion Middleware Technologies: ADF 11 G: generate the primary key sequence number

  Otherwise, instead of DB trigger, create the DB function that retrieves the value of the PK and call stored function in the overloaded method create() entity:

• 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.

• Call a page after you have created a primary key?

  Hello
  
  I have a form on a table with a button create on this subject. When I click on the button CREATE and brings back me to this report which shows my new record, the primary key is created. Here, everything's fine.
  
  Now, I want to create a branch to a new page (after treatment), passing the value of my new primary key to this page. But it seems that this value is zero (if I look in the URL there is no value)
  
  For example, I need to create a new customer, then pass the primary key of my client to a new page. But it does not work... someone can help me?
  
  Thank you
  
  Mathieu

  You should take a look in your SRM process and he'll say

  Return key in point

  You must put the name of the key (primary) here like this:

  P1_PRIMARY_KEY

  If you create a new record, the process will get the primary key and set the item with this value. You can refer to this element in your conditional branch and it'll pass this value to your target page. That's essentially what Scott said in his first response.

• How can I update the primary key column

  Hello
  Can you suggest me best workaround/algorithm for task below:
  
  (Oracle 10g, Solaris OS.)
  Location:
  Table a primary key column P 'Code', tables children F1, F2,..., reference to F15 "Code_P' foreign key column"P.Code"column, and we do not know which of the child tables data available for a particular value"P.Code.
  Task:
  Change the value "P.Code" from 100 to 200. So that the result would be that record P [Code = 100] should be updated:

  update P set
  Code = 200
  where Code = 100;

  And child tables 'Code_P' column should be updated as:

  update F1, F2, .., F15 set
  P_code = 200
  where P_code = 100;

  The best solution would be that you can easily repeat this task.

  Will there be FK constraints in place?
  If so, you may need to modify them so that their application may be temporarily deferred.

  The gameplan would be something like this:

  -Making of CF can be deferred, immediate departure.
  -Alter FK set delay.
  -Update of Parent table.
  -Update of the children tables.
  -Immediate constraints set
