• (ORA-00955) conflict of naming for index and constraint when you use a unique index (.. desc,.. CSA)

  Hello

  indexes and constraints are in different namespaces, so it should be possible to give them the same name.

  In the following case that apparently does not work:
  

  create unique index orders_year_show_uq
    on orders (year desc, show_orders asc);
   
   alter table orders
    add constraint orders_year_show_uq unique (year, show_order);
  

  When I run these statement, I get a "SQL Error: ORA-00955: name is already used by an existing object". ""

  If I clean and I execute the same instructions as above with the only difference on the 2 line, using "asc year" instead of "year desc":

  
    on orders (year asc, show_orders asc);
  

  then it success.

  I can't explain it, you have an idea?

  Thanks in advance.

  Kind regards

  Giovanni

  First of all, you have show_orders in index and show_order in the constraint. I'll assume that it's a typo. Second, when you create constraint without index enhance the specification Oracle seeks indexes existing on the same set of columns in ascending order. If this index does not exist (and it's your case, since one of your columns to index is in descending order), Oracle tries to create one with the same name as the constraint. That's why you get ORA-00955: name is already used by an existing object. In general, you can specify explicitly the index name to force the Oracle by using the existing index. But it will not help you. If you issue

  ALTER table orders add unique constraint (year, show_orders) orders_year_show_uq using index orders_year_show_uq;

  You will get the ORA-14196: specified index cannot be used to apply the constraint.

  In any case, Oracle does not support using index DESC for PK/UK.

• Backgrounds of different bodies for the index and the child pages?

  Hello

  Can someone tell me if it is possible to create different background images for the index and the child pages? Thank you!

  Yes it is possible.  There are several ways to do so; one way is to use styles inline like this for each of your pages:

  Good luck.

• reverse key indexes and clustering factor...

  I read the Oracle 11.1 on the reverse key index doc, and I'll try to find the best case to use them (outside extra sequence mentioned in docs)...
  
  But my question would be who would be the real scenario where we could see the benefits of the key index reverse?
  survival gear, I'm harming the key index I wondered how reverse index clusters factor? I'm feelin that factor of clustering are bad/high for them... Am I wrong?

• Difference between the foreign key index and secondary index

  Hello
  
  Suppose we have two primary databases,
  
  Employee (id, company_id)
  
  Company (id, name)
  
  (where: the employee of the company is one to many, and I use the collections API)
  
  If we want to perform a join between the employee and the company based on the ID of the company. I want to know the difference between the following two options:
  
  1 - construction of a secondary index on the Employee (company_id). call this index index1. Then, we use the following code:
  
  For each company c
  index1.get (c.ID)
  
  2 - construction of a foreign key on Employee (company_id) index where the database of foreign key was undertaken. call this index index2. Then, we use the following code:
  
  For each company c
  index2.get (c.ID)
  
  I have two questions:
  
  1 - What is the difference between these two options in terms of performance?
  
  2. I know that one of the benefits of the foreign key are the application of integrity constraints (CASCADE, CANCEL, etc. to DELETE). That declare a foreign key to give me any advantage when I want to do a join? (for example a quick method, or a single statement to a join)
  
  Thank you
  Wait.

  It doesn't matter what the example, the only advantage of a foreign key index (above, the benefits of a secondary index) is that it imposes of foreign key constraints. There is no other advantage to a foreign key index.

• Where is the text for the index and search tabs saved?

  It is specifically in RoboHelp 9 - although the answer may be the same for other versions.

  I wonder, when WebHelp is created, where to get the text to use in the indexing and search tabs?

  Specifically, I'm looking for (and change), the text in the Index tab that reads, "type in the keyword to find:" and the text in the Search tab that reads, "Type in the words to search for:

  I suspect these two phrases are in a file .lng somewhere, and just this file needs to be changed...

  Any ideas?

  The mentioned Colum .lng file are accessible more easily by clicking on file > project settings > Advanced button > LNG tab

  Under LNG, you will see everything most of the default labels for different items. It is better to work here on the source of LNG, rather than trying to change the output WebHelp that will be replaced later the next time that you build.

• Indexes and constraints

  Hi guys!
  
  I did a little test and now I do not understand the result. Please explain to me the following:
  
  (1.) I created the following table emp1
  
  < pre >
  CREATE TABLE emp1
  (
  EmpNo NUMBER CONSTRAINT emp1_pk PRIMARY KEY
  USING INDEX
  (
  CREATE UNIQUE INDEX emp1_idx ON emp1 (empno)
  )
  );
  < / pre >
  
  2.) now, I interviewed user_indexes and user_constraints
  
  < pre >
  SELECT i.index_name, i.index_type, i.uniqueness, c.constraint_name, c.constraint_type, c.status
  From user_indexes i, user_constraints c
  WHERE i.table_name (+) = c.table_name
  AND c.constraint_name AS 'emp1_pk '.
  ORDER BY c.constraint_name;
  < / pre >
  The result displays the following lines:
  < pre >
  INDEX_NAME INDEX_TYPE UNIQUENESS CONSTRAINT_NAME, CONSTRAINT_TYPE STATUS
  ---------------------
  NORMAL SINGLE ACTIVE P EMP1_PK EMP1_IDX
  < / pre >
  
  3.) after that I disabled the emp1_pk constraint and I Redid the same query
  
  < pre >
  ALTER TABLE emp1 DISABLE NOVALIDATE CONSTRAINT emp1_pk;
  
  SELECT i.index_name, i.index_type, i.uniqueness, c.constraint_name, c.constraint_type, c.status
  From user_indexes i, user_constraints c
  WHERE i.table_name (+) = c.table_name
  AND c.constraint_name AS 'emp1_pk '.
  ORDER BY c.constraint_name;
  < / pre >
  The result displays the following lines:
  < pre >
  INDEX_NAME INDEX_TYPE UNIQUENESS CONSTRAINT_NAME, CONSTRAINT_TYPE STATUS
  ---------------------
  EMP1_PK NULL NULL NULL P DISABLED
  < / pre >
  
  So far so good. I got disabling of this constraint is okay to delete the corresponding index. But in the following example, the corresponding index would not be deleted.
  
  < pre >
  CREATE TABLE emp2
  (
  EmpNo NUMBER
  );
  
  CREATE UNIQUE INDEX emp2_idx
  ON emp2 (empno);
  
  ALTER TABLE emp2
  ADD CONSTRAINT emp2_pk PRIMARY KEY to the AID of INDEX emp2_idx;
  < / pre >
  
  2.) now, I interviewed user_indexes and user_constraints
  
  < pre >
  SELECT i.index_name, i.index_type, i.uniqueness, c.constraint_name, c.constraint_type, c.status
  From user_indexes i, user_constraints c
  WHERE i.table_name (+) = c.table_name
  AND c.constraint_name AS 'emp1_pk '.
  ORDER BY c.constraint_name;
  < / pre >
  The result displays the following lines:
  < pre >
  INDEX_NAME INDEX_TYPE UNIQUENESS CONSTRAINT_NAME, CONSTRAINT_TYPE STATUS
  ---------------------
  NORMAL SINGLE ACTIVE P EMP2_PK EMP2_IDX
  < / pre >
  
  The result of this query is the same as emp1_pk. But at the next step, the results differ.
  
  < pre >
  ALTER TABLE emp2 DISABLE NOVALIDATE CONSTRAINT emp2_pk;
  
  SELECT i.index_name, i.index_type, i.uniqueness, c.constraint_name, c.constraint_type, c.status
  From user_indexes i, user_constraints c
  WHERE i.table_name (+) = c.table_name
  AND c.constraint_name AS 'emp1_pk '.
  ORDER BY c.constraint_name;
  < / pre >
  The result displays the following lines:
  < pre >
  INDEX_NAME INDEX_TYPE UNIQUENESS CONSTRAINT_NAME, CONSTRAINT_TYPE STATUS
  ---------------------
  NORMAL EMP2_PK UNIQUE P DISABLED EMP2_IDX
  < / pre >
  
  That's what I did not understand. Emp1_pk has been disabled and the corresponding index emp1_idx was abandoned. Emp2_pk has been turned off but the corresponding index has not been deleted. Can someone explain to me please, the difference between the example 1 (emp1_pk) and example 2 (emp2_pk).

  Hello

  In the first example, Index was done by primary key, and when we disable the primary key, it also drops the corresponding index.
  But in the second example, the Index is created on the column separately and then the primary key is created. Now that there is already an index on the primary key column will use this existing index and when we disable the constraint this index will not be droppped because it was not created by primary key. It was only used by primary key.

• Signature request failed for key RRT and CPR

  Hello world

  I received 3 csi lines of RIM to sign my application. I recorded these 3 keys without problem.

  When I try to sign my application, I correctly get signature only for applications RBB. RRT and CPR requests fail: "the signature on the code signing application did not check.  The probable cause of this problem is entered a wrong password CSK. »

  I checked the passwords. The same goes for these 3 files.

  I use JDE 4.2.1.

  It is a problem of password.  I recommend removing your keys and start over with a new series.  You can request new keys (for free) here: https://www.blackberry.com/SignedKeys/

• Is there a difference between old W7 for 10 months and the current version?

  A year ago, I bought an HP computer and got the drive of W7 a few months later, but never installed. Do I have to install or download the last update? There were bug fixes and improvements over the last 8 months? I have the choice to install W7 disk I had in February and stay with it; buy the upgrade from Vista to W7 or install my drive and get the upgrade at any time of W7. I use the computer at home and need a few bells and whistles. I heard that the early W7 was not great. Thanks for the tips

  Hello

  It is not released a newer version. All bugs that have been found since this date can be fixed by runing Windows Update.

  Do not buy the new copy. Use what you already have.

• Help. I need help for the upgrade and the English Version for my Acer One Notebook

  I have an Acer One Notebook all in Japanese and to go to the English version and its still a product of windows 7. What kind of windows program should I update and do so as English version?

  Thank you

  Option 1: You have to upgrade your current edition to Windows 7 Ultimate.

  Option 2: You need to download and install the copy of English language of the current edition you have installed.

  Your options are very limited. I honestly would buy 10 Pro in Windows and install in English.

• Portege R700 - no autorun for CD/DVD and USB keys

  In my Portege R700 there is no way to make autorun works (for key USB and CD/DVD as well). CD/DVD and USB keys work perfectely, but not the autorun.

  I tried to use both the automatic repair of Microsoft and PowerToys, but the problem that it is still there. I also tried to change the registry, but it seems that the changes are not retained. I suspect that it is something related to some utilities or so.
  Can someone help me?

  Thanks in advance.
  Gerlando

  Hey,.

  > I suspect that it is something related to some utilities or so.
  What utilities you have installed? Theoretically, they could block the autorun

  Normally if autorun doesn t work on XP, you can enable it in the Windows registry:
  Start > run > regedit

  The registry editor will open and go to:
  HKEY_CURRENT_USER / Software / Microsoft / Windows / CurrentVersion / policies / Explorer
  Double-click the NoDriveTypeAutoRun value and set the value of 91.

  Now he must navigate to:
  HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Services / Cdrom

  Double-click the AutoRun value and set the value to 1.

  Now restart your computer and try it again, usually autorun should work again.
  Additionally, make sure that the latest Service Pack is installed for XP (SP3).

• ORA-01418 for an index.

  Hello
  
  I have the following problem. I can't drop or change a return to index a unique constraint (primary key constraint). The index and constraint have the same name. I always get the error ORA-01418.
  
  What could be the reason for this strange behavior? Index constraint/is known, because the views all_constraints resp. all_indexes show that. Will there be a brute force method to deposit such things and create a new?

  Usually its difficult to believe when someone says something dubious, until and unless it don't stick the sqlplus output.

  So, just for us your alter index index-name command and select of all_indexes where index-name = "YOUR_INDEX_NAME".

  A guess, that you have created indexes with qutation mark "'"and now (alter index...) " you use no quotes.

  Because for ORA-01418; answer is "Specify the name of an index in the ALTER INDEX, DROP INDEX, or VALIDATE INDEX statement".
