• Creation of primary keys, foreign keys and indexes

  Hello
  
  I created 60 new tables based on 60 existing tables.
  
  The 60 current tables are named FY11_ACC1, FY11_ACC2, FY11_SALES1, FY11_SALES2..., but all of the 60 tables start with FY11. I created the same structured tables but with names like FY12_ACC1, FY12_ACC2, FY12_SALES1, FY12_SALES2 FY12...
  
  I used the below SQL and generated SQL code.
  
  Select 'create table ' | Replace (table_name, 11, 12).
  ' in select * from '. table_name | "where 1 = 0'.
  from user_tables;
  
  But this did not generate the PRIMARY KEYS, FOREIGN KEYS and INDEXES. How can I automatically or with similar like SQL above? _
  
  Thanks for your time and your help.

• Problem with the primary key and indexes

  Hi all
  
  I'm looking a mess on one of our main tables.
  One of the developers here added an index on 3 columns in the table, thinking that it would speed up (not noticing that it had not a PK).
  
  Subsequently another developer has noticed there do not have a primary on key. So they added a touch of primry on the single column.
  
  The problem is that now the index created on 3 columns is bein used as the primary key index. As when the primary key is created a new index was not created.
  
  Is there anyway to get rid of this index/change it correct?
  
  This table is related to many many other tables, so when we tried to remove the index we could not due to the primary key and foreign key violations with other tables.
  
  Thanks in advance

  Oracle, as you found, is quite capable to use a column enformce multi index a single column primary key, as long as the pk column is the leader in the index. This should not cause performance issues for a search of PK and if the three indexed columns are often selected only may benefit from these types of queries.

  The only way to change that now, would be to drop all CF, drop and add the PK constraint and then add all the FK constraints. A long time and potentially dangerous (if you miss to add back of the FKs) endeavour. Certainly not worth the risk in my opinion.

• Satellite L850 - 1 H 4 - a strange problem with the FN key

  Hello

  I have a strange problem on my laptop. When I uninstall my PVAT my start "FN" key works, when I install it it s not working not properly. Its market not only the volume key (F9 and F10) without pressing the "Fn", if I want to press F9 or F10 I have to press FN + F9, even with the rest of the buttons.

  When I install PVAT I have to press FN, so I can use my F keys (e.g. F3 to search on the browser tool, alt + f4 - I have to press Fn + alt + f4), and I can't use real functions like mute, disable Touchpad etc. Use the volume keys only. Y at - it a problem if I run my computer without PVAT, this may affect its performance?

  Where could be the problem and can I fix it? I'm with Windows7 x 64, but the laptop was with no OS when I bought it. And there is a problem with this version, I bought its impossible to install the Pakc3 Service, it s with SP1, can be the problem? I put t know what to do... perhaps I run the laptop without PVAT, sounds good, because the buttons work fine without it, but I don't know if it interacts with something else.

  Thanks in advance!

  Its possible to use the function buttons by pressing another button without the use of the fn or FN.
  This option can be changed in the BIOS.

  Go to the BIOS by pressing F2.
  In the BIOS, choose Advanced-> system configuration Options
  Here you should find the option that allows to change the special function keys which allows you to use the function FN or without button Fn button

  By the way: this theme has already spoken here in the forum several times. therefore recommend that you use the advanced search to Forums before posting new thread

• Strange problem with HorizontalFieldManager - it does not show on real device bitmap

  I have a rather strange problem with the HorizontalFieldManager on my Blackberry 8820, which I did not on the Simulator, or done other blackberries that I tried to install my game.

  The problem is that bitmaps that I add, do not appear on the actual device, as in the images below. The code is provided below as well. No idea how to debug, or resolve is appreciated.

  Here's what I see on Simulator and some devices

  

  Here's what I see on the real blackberry:

  

  Code:

  ......

  OK, I found the solution - the problem is that there seems to be a bug where you can't put more fields button radio on a horizontal layout manager with 4.2.2.x.

  The solution is to extend the RadioButtonField field and replace the positioning method:

  RadioButtonField radioField = new RadioButtonHack ("", textureGroup, isSelected);

  SerializableAttribute public class RadioButtonHack extends RadioButtonField {}

  public RadioButtonHack() {}
  Super();
  }

  public RadioButtonHack (String label, group RadioButtonGroup,
  Boolean selected, long style) {}
  Super (label, group, selected, style);
  }

  public RadioButtonHack (String label, group RadioButtonGroup,
  Boolean selected) {}
  Super (label, selected group);
  }

  public RadioButtonHack (label As String) {}
  Super (label);
  }

  Protected Sub layout (int width, int height) {}
  int temp = this.getPreferredWidth ();
  setExtent (time, height);
  Super.Layout (time, height);
  }

  }

• Strange problem with addinstance, first page not save

  So I spent some time designing a form for a local police department to facilitate their reports.  I'm having a strange problem using addinstance.

  Use the two separate sections of the addinstance form; subject/witnesses/victims and the narrative section.  The two sections have buttons add and remove additional if necessary pages.

  • The witness/subject/victim section works as expected, additional pages can be added or removed, and they are preserved when you save the document, and then reopen the document
  • The narrative section does not work as expected, other pages can be added or removed.  The problem comes when the document is reopened, the first page which is generated using addinstance is no longer present in the file, all the pages generated after the first page that has been deleted remains.  It is extremely strange, and I have no idea what is the cause.

  Some possibilities I have already looked at in

  • Document is saved in dynamic form
  • Type of the Interactive preview
  • form is presented in preview as a form xml dnymaic
  • automatically keep your changes to scripts to form when registering
  • I use acrobat x to activate additional features so that end users can fill in the form and save it using the adobe reader software

  Here is the link to the file, I have been unable to share via acrobat.com http://www.FileSwap.com/DL/kp2BTWSTQR/

  Any help would be greatly appreciated, I have no idea on how to solve this problem!

  Hi Ian,

  I think you have little code in the form1 docReady event that are causing you problems.  There are also exceptions to come JavaScript, it looks like test code, but you got "display the console on errors and messages" in Reader/Arobat (Edit... Preferences... JavaScript)

  Good luck

• Satellite P300 - strange problem with num lock keys

  I had a problem with my keyboard lock num. I have a P300D - 131

  By pressing '4' and '8' at the same time, it shows on the screen '4 '.

  By pressing "0" and "6" at the time, tamed, it shows on the screen "0 0".

  This also happens if I touch the very fast numbers. That's why you can't count on the num lock keys! I have this problem since I bought the laptop in July 2008. Now, I found this forum and I hope that really that someone can help me solve this issue!

  Thank you

  Hello

  These issues in the past have been resolved with BIOS update. I therefore recommend as a first step of the BIOS update.
  Check the current version on your laptop and the most recent proposed on the Toshiba download page.

  To be honest I don't understand why you waited so long on this subject. Laptop warranty valid and the nearest Toshiba authorized maintainer can help you about this.

• To index foreign keys in 11 g?

  Hello
  
  We are on 11.2.0.2 on Solaris 10. A day back I had a mistake in our application due to a blockage. The trace file indicates that a single sql and the table. The table involved is a parent to a child table table and the foreign key of the child table is not indexed. What is the reason for the deadlock? Are foreign keys should be indexed in 11g also?
  Note that the trace file has this statement: ("" the only resource deadlock: block the queue blocking himself, f 0 ' ").
  
  It's the statement recorded in the trace file:

   delete from tab1  a where exists (select 1 from tab1 where col1 = a.col2 and col3 = :1) . 

  Here the col1 is a key to parent to an another table tab2 which has the same col1 column, but it is not indexed.
  
  (I changed the names of the tables and columns to remove our specific details of the app).
  Parts of the trace deadlock below:

  So I think you have your first suspect.

  It is always helpful if you can come up with a script to reproduce the problem outside the application and then test that the foreign key indexing fixes the problem.

  I hope that you would be able to lead to a test that relate to what your application is doing - you may have to really follow the sessions to discover all of the States involved.

  But for something completely artificial:

  SQL> create table parent
    2  (col1 number not null primary key);
  
  Table created.
  
  SQL> create table child
    2  (col1 number not null references parent(col1) on delete cascade
    3  ,col2 number not null);
  
  Table created.
  
  SQL> insert into parent values(1);
  
  1 row created.
  
  SQL> insert into parent values(2);
  
  1 row created.
  
  SQL> insert into parent values(3);
  
  1 row created.
  
  SQL> insert into child values(1,1);
  
  1 row created.
  
  SQL> insert into child values(2,2);
  
  1 row created.
  
  SQL> commit;
  

  Session 1:

  SQL>  update child set col2=col2+1 where col1 = 1;
  
  1 row updated.
  
  SQL> 
  

  Session 2:

  SQL> update child set col2=col2+1 where col1 = 2;
  
  1 row updated.
  
  SQL> 
  

  Session 1:

  SQL> delete from parent where col1=1;
  

  Session 2:

  SQL> delete from parent where col1=2;
  

  Which translates this in session 1:

  delete from parent where col1=1

  The following deadlock is not an ORACLE error. It is a

• Problem with keyboard: some keys return two, not one, characters

  I have a MacBook Air 11 '' mid-2012 128 GB SSD model running OS X Yosemite 10.10.5 and my keyboard has developed a strange problem occultation key repeat.  Whenever you press the "3" button, the system generates thus simultaneously a '3' and '6 '.  This motif is repeated this diagonal of the keyboard down, i.e.

  '3' generates a '3' and '6 '.

  'e' generates an 'e' and a 'y '.

  "d" generates a "d" and an "h".

  'c' generates a 'c' and a "n".

  The reverse is also true, that is, a '6' generates a '3' and so on.  Curiously, the sign '=' generates a character "§" as well, a special character generated by keeping down option and pressing "6".

  (This combo generates a ' § ' and a ' £', hidden under the '3'.)

  The same problem occurs when you use the Shift or Control keys as modifiers.

  I can work around the problem by using either a connection wireless Bluetooth or wired USB keyboard (like using the "Keyboard Viewer" option under "System Preferences"), but that kind of defeats the point of having a laptop as a MacBook Air, Yes?  The problem is intermittent, but becomes very annoying.  (Try to type a password with such a mess!) It sounds like a mechanical problem requiring a possible replacement of the sale wholesale (and), but I hope someone out there can have a software or another solution.  Thank you!

  That certainly points to make it a hardware problem.  It is difficult to imagine a software problem that would not affect both internal and external keyboards.

• Foreign key delete rule: no matching combination does not show a difference to compare models

  Hello

  I've noticed that if there are in the relational model a foreign key with delete rule NO ACTION and in the database (Data Dictionary), the delete rule is RESTRICT, no difference appears in the dialog box to compare. The difference is displayed if the delete rule for example is CASCADE and RESTRICT.

  Kind regards

  Robert

  Hi Robert,.

  Thanks for reporting this problem.  I connected a bug on this subject (21754221).

  This situation does not normally flow when an Oracle database is imported, but may occur when importing other types of database.

  Kind regards

• index and foreign key

  I just read an article on the index.

  Jonathan Lewis - during indexing

  The author says that if you update the primary key or a unique key at the end of 'parent' of the referential integrity constraint Oracle locks the "child" table to find the rows of children committed and uncommitted if a suitable index does not exist. After that he says do not create indexes 'foreign key '. I mean, there is a contradiction. What do you think?

• ODI is not able to detect the primary/foreign keys to XML - the user has no privilege or object not found

  Hi guys,.

  Im trying to load an XML with the address of two entities and employee as below. The topology of reverse engineering, everything works well. Even able to display the xml data in ODI, but when I try to load the data of these two entities join by the schema of the primary keys and foreign keys which created odi engineering process reverses for xml, im im getting the error below.  IM able to load an entity data, error occurs only when I use the join odi creates internally to identify employees for xml and address components

  It is clear from the content of the xml file, you have given here. In this xml file, you have four type of complex. Two of them are employed and address. However the employee doesnot has nothing to do with the address that you have not added the relationship. That is why its failure. This isn't the fault of the ODI.

  Also I suggest not to use self-generated by ODI dtd that you might face problem in the future. For example, the address of XML type has 8 attributes, and 4 of them are not mandatory. This means that each of your xml file may have attributes between 4 and 8.  That's where ODI auto generated DTD fails.

  ComplexType element XML schema

  Thank you

• foreign key 'generate' strange behavior check box, any idea?

  Summary: in the properties of the table, the foreign keys, the box generate behaves badly, and I don't understand why or how I got there.

  Oracle Data Modeler 4.0.2.840 8.1 X 64 Windows, jdk1.7.0_55

  the behavior is:

  (1) add the foreign key (two different more to see strange behavior)

  (2) uncheck 'generate' on a foreign key

  (3) apply, Ok

  (4) ask 'Preview DDL', a foreign key constraint is generated, SO FAR SO GOOD, I'm happy

  5-now click on the button 'generate the DDL' for any design = > * * TWO foreign keys are generated?

  (6) even more strange: sometimes the 'generate' check itself after step 5, most of the time is not

  (7) at the beginning this has occurred for a couple of foreign key 'uncheckees', now it almost always happens.

  The relational model was built by importing the SQL scripts already exist (try to migrate the Data Modeler). No too complex ~ 115 tables, 12 times.

  I think it's a bug, but I can't find any reference on the web, maybe I do something wrong?

  Hi Michel,.

  The generation is different depending on whether or not the relevant storage design is open.

  If the design of the storage is not open, the option "Generate DDL" on the foreign key is taken into account (for an overview of the DDL or full generation of DDL).  For an entire generation of DDL, the foreign key will initially not selected phase in the generation of the DDL if Options the option "Generate DDL" on the foreign key has been disabled.  (This change in the phase of the generation of DDL Options will also cause the option "Generate DDL" on the foreign key update.)

  If the design of the storage is open, the option 'generate DDL"on the foreign key has no effect (in a Preview of DDL or full DDL generation).

  Also in a generation full of DDL, an object will be initially marked as not selected if it has been disabled in the previous generation of DDL.

  I hope that this helps to explain the behavior that you find.
