• With the help of the ORA-00904 granted by ROLE

  Hi all

  I have an error using the grant through ROLE (Oracle 11.2.0.1 on redhat Linux)

  Here is the explanation of my problem:

  I create a package to wear patterns

  create or replace 
  PACKAGE                     usera.pkg_utils AS 
   function f_my_function return RAW;
  END pkg_utils;
  

  I create the package body:

  create or replace 
  PACKAGE BODY usera.pkg_utils  AS 
   function f_my_function return RAW  is
    v_uuid RAW(16);
  begin
    v_uuid := sys.dbms_crypto.randombytes(16);
    return (utl_raw.overlay(utl_raw.bit_or(utl_raw.bit_and(utl_raw.substr(v_uuid, 7, 1), '0F'), '40'), v_uuid, 7));
  end f_random_uuid;
  END pkg_utils;
  

  I create a 'R_ROLE1' role to which I admit "EXECUTE ON USERA. PKG_UTILS TO R_ROLE1.

  I give you that R_ROLE1 to the PUBLIC so that each user can access the package USERA. PKG_UTIS

  If I call another user f_my_function, it works well.

  If I call another user from a procedure f_my_function I get "ORA-00904".

  ex: to UserB

  create or replace 
  PROCEDURE P_PROC
  AS
  num int;
  uuid_ RAW(16);
  BEGIN
      select usera.pkg_utils.f_my_function() into uuid_ from dual;
  END P_PROC;
  /
  

  If I give you that directly "GRANT EXECUTE ON USERA. PKG_UTILS TO PUBLIC' so it works well.

  Thus, the error comes from the fact that I use a role, but I can't fix it. I don't understand why USERB does not use its grant to the role of r_role1 granted to PUBLIC.

  Is there something as USERB is unusable cascade role during the call to a procedure? is there something to "activate"? ".

  Thank you all

  Operation of the roles in PL/SQL blocks

  The use of roles in a PL/SQL block depends on if it is an anonymous block, or a block named (stored procedure, function, or trigger), and if it runs with the rights of the author or the rights of the applicant.

  Roles used in the appointed with rights to define blocks

  All roles are disabled in any PL/SQL block named (stored procedure, function, or trigger) that runs with the rights of the author. Roles are not used to privilege control, and you cannot define roles within the procedure of a DEFINER rights.

  The SESSION_ROLES view shows all roles that are currently enabled. If a named PL/SQL block that runs with Definer Rights queries SESSION_ROLES , then the query will return no rows.

• How to set the condition of rule to check the Primary Key, Foreign Key and Unique

  I use Oracle 10.2
  Could someone tell me please how to set the rule condition to check the primary key, foreign key constraint of uniqueness?

  Hello

  Primary key, unique constraints and foreign key are better applied using the native functionality of database constraint. If you like the rules to check if a key exists at the time of the evaluation, you can use a function defined by the user in a rule condition and this function can ask to turn the table keys.

  Hope this helps,

  Is it an upgrade license?

  However, the requirements for the media upgrade is that you have an operating system already eligible such as Windows XP or Vista installed to use it. Since the Windows 7 end user license agreement.

  15 UPDATES. To use upgrade software, you must first be licensed for the software that is eligible for the upgrade. After the upgrade, this agreement takes the place of the agreement for the software that you upgraded. After upgrade, you can no longer use the software that you upgraded.

  So, if you are always denied, you will just have to reinstall Windows XP or Vista and let it do the verification of eligibility.

• Questions about the creation of a foreign key on a table

  Hello @ll,
  
  during an update of the database, I lost a foreign key between two tables. The tables are called werteart and werteartarchiv_pt. Because of its size, werteartarchiv_pt is a partitioned table. The missing foreign key was a constraint on werteartarchiv_pt table referencing werteart.
  
  Some statistics on the size of the mentioned tables:
  werteart 22 MB
  werteartarchiv_pt 223 GB
  werteartarchiv_pt (Index) 243 GB
  
  I tried to create the foreign key again but it failed with the following error (apologies for the German error message):
  
  sqlplus ORA-00604: Fehler auf rekursiver SQL-ebony 1
  sqlplus ORA-01652: Temp-Segment kann nicht um 128 in Tablespace TEMPS00 judgements
  
  The statement that I used:
  
  ALTER table werteartarchiv_pt
  Add constraint werteartarchiv_pt_fk1
  foreign key (rail, werteartadresse, merkmale)
  Reference werteart (rail, werteartadresse, merkmale)
  on delete cascade
  at the delayed start can be delayed;
  
  So, the problem seems to be that Oracle needs a lot of temporary tablespace to generate foreign key and I do not know how and why.
  
  My questions now are, and I hope that someone is there who can answer all or part of it:
  
  (1) why Oracle should temporary tablespace to create the foreign key? The foreign key uses the same columns as the primary key.
  
  is 2 (a) possible to change the statement without using the temporary tablespace?
  
  2 (b) if it is not possible to avoid the use of temporary storage space, is there a formula how to calculate the necessary temporary tablespace?
  
  (3) is it possible to modify data in tables while the foreign key is created or is the whole table locked during the process?
  
  Any help or advice is appreciated.
  
  Kind regards

  Because it is data validation to ensure that the foreign key are violated. If you had specified NOVALIDATE ACTIVATE in its creation then the existing data in the table should be checked and the statement must fill out instantly (future data added is enabled by the constraint).

• Hard drive failure: have a few questions!

  Some info about my computer:
  • Toshiba Satellite laptop P755
  • There was more than one year
  • Windows 7 Home Edition Premium came with the laptop.
  Hello
  In the last few days I received an error saying that my hard drive can fail at any time, and for this reason, I have to back up my files. I run that a full backup as Windows Error Message had recommended that I do, but instead I just backed up my important files on a USB key. Finally, I know that my hard drive will fail, and at this point I am waiting. I am looking to buy a new HDD replacement , but I have a few questions that NEED to know before you proceed with the replacement of my current hard drive. Since I'm getting a new hard drive, should I buy a new key to activate Windows 7? Under my laptop, I have a Windows 7 Home Premium product key and my friend said that I will be able to borrow his Windows 7 Home Premium CD to install the operating system on my new hard drive. So do I still need to buy a new copy of Windows 7? I looked around forums and some people responded by saying that I won't need to buy a new copy of Windows 7 and when I install Windows on the new drive, it will be recognized that I had a genuine Windows 7 operating system. I had also heard tell that if I turned off my key using CMD, then I could re - use my key to install Windows. That's really all that I have questions, and I hope that this gets answered. Thank you.
  I also ran a scan through my hard drive and here are the results.
  
  

  Hello

  When the new drive arrives and it is installed, you shouldn't have any problems activating you replace just the hard drive and not the motherboard. The motherboard is what is important in the main OEM installations. If you have a COA sticker at the bottom of the laptop, or elsewhere, it will be what you use to activate Windows.

  If you have however poorly (you shouldn't), don't panic, just follow the phone activation method and you will be straightened out:

  1. start > Search > in the search box, type slui.exe 4
   
  2. press the key "enter".
   
  3. Select your country in the list
   
  4. choose the phone Activation
   
  5. stay on the phone and wait for an operator to help you, do not press the buttons, etc. Once you get an operator, explain your activation trouble and you should be set.

  Kind regards

• Optimize the foreign key for the removal of the cascade constraint.

  Hello

  JDeveloper version: 11.1.2.3.0

  I saw this blog and found something new to me: http://snag.gy/qI6dY.jpg

  Jdeveloper user interface, there is an option to select all tables to select the foreign key and set it for the removal of the waterfall.

  My project is deployed on multiple databases. I wonder where this change is registered. None of the project files is modified.

  Can I make this change (from limitations to the waterfall) for each database that I use?

  Here is the blog where I saw that: http://tompeez.wordpress.com/2013/04/22/master-detail-insertdelete-sample/

  I have my object associations optimized for the removal of the waterfall, but without the option above together, I always get constraint violations...

  Concerning

  Not sure however if you set the option the DOF looks like

  	"EMP_JOB_FK' FOREIGN KEY ('JOB_ID') CONSTRAINT
  	REFERENCES 'HR '. "" SELECT JOBS "("JOB_ID') WE DELETE CASCADE

  If you set the option to cascade for fk Job_id from the employees table.

• "ORA-00904 of invalid identifier", what's the problem?

  Hey,.

  I am trying to create very basic (via Script Editor) 4 tables in Application Express 4.1.0.00.32 and get this error and cannot understand why. If anyone can point out where I am going wrong would be perfect!

  Here's the script:

  ----------

  Drop TABLE County CASCADE CONSTRAINTS ;

  Drop TABLE City CASCADE CONSTRAINTS ;

  Drop TABLE Offence CASCADE CONSTRAINTS ;

  Drop TABLE Region CASCADE CONSTRAINTS ;

  
  

  CREATE TABLE County (

  PRIMARY County_Name VARCHAR2()55) KEY

      Rental VARCHAR2 (55) ,

      Details VARCHAR2 (222) );

  
  

  CREATE TABLE Offence (

      Offence_ID NUMBER (3) PRIMARY KEY ,

  Offence_Desc VARCHAR2()333)

  Offence_Type VARCHAR2()111() NOT NULL

      Date DATE NOT NULL ,

      Time NUMBER (5) ,

  County_Name VARCHAR2()55( ) REFERENCES County()County_Name)

  City_Name VARCHAR2()55( ) REFERENCES City()short-term()

  Region_Name VARCHAR2()55( ) REFERENCES region()rated()()

      Building_Name VARCHAR2 (55) );

  CREATE TABLE Region (

  PRIMARY Region_Name VARCHAR2()55) KEY

      City VARCHAR2 (55) NOT NULL ,

      Est_Population NUMBER (9) NOT NULL );

  -----------

  
  

  The error I get in the summary when I run the script is:
  

  6 «»

  CREATE TABLE offence (Offence_ID NUMBER PRIMARY KEY (3),)

  "ORA-00904: invalid identifier.

  So I guess it's related to the "Offence_ID" line (designed as the primary key / identifier), but I don't see a problem.

  Any help is greatly appreciated!

  The DATE is an Oracle reserved word.

  Oracle reserved words and keywords

  SQL > create table test_tbl

  () 2

  3 date default sysdate

  4  );

  date default sysdate

  *

  ERROR at line 3:

  ORA-00904: invalid identifier

  SQL > create table test_tbl

  () 2

  3 'DATE' date default sysdate

  4  );

  Table created.

  I wouldn't recommend do not name your DATE column, but to use something like Offence_date instead.

• Is a foreign key MUST have a UNIQUE or PK column as a reference?

  First I tried, from what I saw Yes it must be Unique or PK. Secondly, I am pretty sure that I read somewhere where there are PK or unique. Thirdly, I checked oradocs and other pages, the thing ends, I owe an answer

  Constraint foreign key (also called a constraint referential integrity) designates a column as a foreign key and establishes a relationship between this foreign key and a primary or unique key specified, called the referenced key.

  
  

  This implies, but does not explicitly specify that it MUST be a PK or a SINGLE.

  
  

  Basically I want a simple yes/no answer just to give me some peace of mind. I don't want to waste any time, but changes to the oracle from time to time, and I'd rather have a confirmation from someone with more knowledge/experience.

  
  

  Thank you!

  Yes.

  This same document you are referencing tells you what are the rules for the creation of a foreign key.

  Data integrity

  Foreign key constraints

  Whenever two tables have one or more common columns, Oracle database can apply the relationship between the two tables with a foreign key, also called a referential integrity constraint constraint. The constraint requires that for each value in the column on which the constraint is defined, the value in the other specified that another table and column must match. An example of a referential integrity rule is that an employee may work for only one Department.

  Table 5-2 lists the terms associated with referential integrity constraints.

  Table 5-2 referential integrity constraint conditions

  Term

  Definition

  Foreign key

  The column or set of columns included in the constraint definition that refers to a key that is referenced. For example, the department_id column employees is a foreign key that refers to the department_id column of departments . Foreign keys can be described as several columns. However, a composite foreign key must refer to a primary or unique key with the same number of columns and the same types of data.

  The value of the foreign keys can be either the primary or unique key value referenced or be null. If any column of a composite foreign key is null, then the portions not null the key do not match any corresponding part of a parent key.

  Referenced key

  The unique key or the primary key of the table referenced by a foreign key. For example, the department_id column departments is the key referenced to the department_id column of employees .

  Table dependent or child

  The table containing the foreign key. This table is based on the values present in the primary or unique key referenced. For example, the employees table is a child of departments .

  Referenced or the parents table

  The table that is referenced by the foreign key of the child table. It is the key to this table reference that determines whether specific inserts or updates are allowed in the child table. For example, the departments table is a parent of employees .

  The first three terms defined in the table EXPLICITLY State references to the 'core' or 'unique' keys to the parent.

  The doc also refers to the Application Developer Guide:

  Maintaining the integrity of the data in Database Applications

  Foreign key references a primary key by default

  If the list of columns is not included in the REFERENCES option when you set a FOREIGN KEY constraint (simple or composite column), then Oracle database assumes that you want to reference the primary key of the specified table. You can also explicitly specify the columns to reference the table parent in parentheses. Oracle database checks automatically to check this list of column refers to a primary or unique to the parent table key. If it isn't, an informative error is returned.

  That the entire paragraph is as explicitly as it gets.

  No list of columns? Oracle then checks for a primary key.

  There is a list of columns? Then Oracle 'control to verify this list of column made reference to a primary or unique key'...

  Have you read this statement ? It explains how to set the registry value:

  If the REG_SZ useDefaultTimer does not already exist, you must create it under HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\CVI Run-Time Engine\cvirte. "" This can be done navigate to the appropriate folder, and then click Edit "New" string value. Then, click on means the name of the new value created, select Rename, and then specify useDefaultTimer as the name. Finally, double click on the name and specify the value True or False.
