• Any version of the document database oracle for other languages?

  The Oracle documentation itself is always in English, although in the last translations have been completed (up to Oracle 7, if I remember correctly). There are some translated 3rd party books on the market, you can get your tongue in an online bookstore.

• filling of datetime column SQL Server with the data in the date column oracle

  After a lot of "finangling", I think I have my link dg4msql works well between Oracle and MSSQL.
  
  Now, what I'm trying to do, is fill a table in MSSQL with an Oracle table column values, whenever a new row is inserted in the Oracle table. I use a very simple trigger on the oracle table that goes basically like this:
  
  mware is dblink to MSSQL database, oracle col worth DATE and mssql col is of type DATETIME
  
  This is the relaxation: (edited to show only the column in question)
  ==================================================================================
  CREATE or replace TRIGGER < oracleowner >. INSERT_INTO_NVDB
  AFTER INSERT ON < oracleowner >. < oracletable > for each row
  BEGIN
  insert into '< mssqlowner > '. «< mssqltable > @mware «»
  (
  "load_date_time,"
  )
  VALUES)
  : new.loading_date,.
  );
  
  END;
  ==================================================================================
  
  Now, when you enter a record in the Oracle trigger triggers ok table but does not insert a date in the MSSQL table, the 'load_date_time' in the mssql table can have NULL values so I guess there just inserts a null value.
  
  When I activate the triggers on the table MSSQL, which then takes these values and inserts them into another table with values from other tables, inserting in the Oracle table fails because the relaxation on the MSSQL database tries to pass the date (which is empty) table MSSQL in another table where the datetime field is not null.
  
  I guess it's because Oracle date format is not compatible with MSSQL, which I think is "yyyy-mm-dd hh: mm:"- so I have to either convert the date format by default Oracle to match a MSSQL, or convert a char of the trigger value. (The developer of the side MSSQL says if I can convert it to a char value that should be ok too)
  
  I think that it is probably better to leave it in the date format, the best way to do this would be to put an "alter session set nls_date_format ="at the beginning of the trigger?
  
  Can I convert the date to char the trigger easily? If there is a better way to proceed in the way I approach it I'm all for it.
  
  Thank you!

  Hello
  Your best option is to explicitly convert dates Oracle in a format recognized by SQL * Server. It's more coding, but then you know exactly what is being inserted and you give more control, if anything changes. You can also code to handle null data.
  I'm not sure than to try to change the format of date to 'alter session... ". "do what you want.
  You can use "to_char" on a date into character data-

  To_char (, "HH24:MI:SSxFF of MON-DD-YYYY")

  and use any mask format supported.
  You also use 'to_date' to transform the character data in a date format, as well as 'to_char' and 'to_date' in combination.
  For example -.

  SELECT TO_CHAR (TO_DATE (October 27, 98 ',' DD-MON-RR'), 'YYYY') 'Year' FROM DUAL;

  This is all discussed in the documentation-

  Oracle® database
  SQL language reference
  11g Release 2 (11.2)

  where it also describes the different format masks.
  If you need further assistance on the use of to_date, to_char formats then ask in the forum SQL/PLSQL.

  SQL and PL/SQL

  where they have more experience.

  You can usually speed up the units of PL/SQL compile native code (code system processor-dependent), which is stored in the SYSTEM tablespace.

  You can compile natively any PL/SQL for any unit, including those providing the database Oracle.

  The program compiled natively units work in all environments of servers, including the configuration of shared server (formerly called "multi-threaded server") and Oracle Real Application Clusters (Oracle RAC).

  And this from the section How PL/SQL Native Compilation Works
  >
  How does the Native Compilation of PL/SQL
  Without native compilation, statements from PL/SQL in a PL/SQL unit are compiled into an intermediate form, the system code, which is stored in the catalog and interpreted at run time.

  With native compilation of PL/SQL, PL/SQL instructions in a PL/SQL unit are compiled into native code and stored in the catalog. Native code should not be interpreted at the time of execution, so that it runs faster.

  Because the native compilation applies only to the PL/SQL statements, a unit of PL/SQL that uses only SQL statements may not work faster when it is compiled into native mode, but it works at least as fast as the interpreted code. The compiled code and the interpreted code are the same library calls, their action is the same.

• Need to WF_COUNTRIES and WF_WORLD_REGIONS of the Academy of Oracle PL/SQL tables

  Hello world
  
  I hope someone here has access to these 2 items.
  
  I need to the WF_COUNTRIES and WF_WORLD_REGIONS tables.
  
  The SQL to create these may be all that's necessary and the easiest way to do it for me.
  
  Explanation:
  
  
  I try to make the class trip adventure since Oracle Academy in the APEX and finished project, but our schools APEX accounts were deleted, prematurely (says my instructor). I still have my Oracle Academy connection for the PL/SQL course (and I finished the last class), but never connected to this term to see even if the data WERE never there. I asked an APEX Oracle workspace and requested that they include the necessary data for the project, but he seems almost automated, because my application been approved quickly, and data were not included.
  
  I need these 2 tables for the project, I need of graduates of this program (a class that I needed was not available, so I bought a substitution to do an additional project). I already wrote the Oracle Academy team but they have not yet responded, (2 days and I sent an e-mail Thursday evening/Friday morning).
  
  This has already cost me days of work time and put things on hold, so if anyone has these tables, which would be more useful.
  
  I don't know how to contact me here, perhaps, we can understand that, I'll check this forum.
  
  Thank you very much!
  
  Erichter

  Have you tried google? search for 'create a table WF_COUNTRIES' (including the quotation marks) returns only one, inside you will find create table statement for the named tables. Maybe they fit your needs.

  user name: sys
  password: enter_your_correct_password given at the time of the installation of oracle

  role: select sysdba if you would connect as sysdba otherwise select normal for users other than the sys

  HostName: Enter your ip or hostname of the oracle example server address:-192.168.11.12

  to find the terminal/command prompt open hostname in oracle installed machine
  type---> hostname

  type ping hostname--->

  You can find the IP address of the server

  Port number: 1521 (default)---> I guess, otherwise check the port number in the file tnsnames.ora under your ORACLE_HOME/network/admin folder

  SID: DB1

  try it

• Taking JDBC connection configuration supported the RAC in Oracle SQL Developer?

  How can one Oracle SQL Developer be configured to successfully connect to a [Oracle RAC | http://en.wikipedia.org/wiki/Oracle_RAC] environment, that is, not only the installation program always to connect to one of the individual nodes?
  
  [http://programmersjournal.blogspot.com/2008/08/jdbc-connection-string-for-oracle-rac.html] is an example of a classic and taking version supported the equivalent CARS of a JDBC connection string. I've used a CAR of the same format connection string from within Java applications custom without problem. I thought that the same thing should be configurable in Oracle SQL Developer, by setting the 'Connection Type' drop-down menu on "Advanced", then enter the connection string JDBC RAC-aware as "Custom URL JDBC". However, after the test connection, the following error message is displayed at the bottom of the dialog box:
  
  Status: Failure-Test failed: IO exception: NL Exception has been generated
  
  There is no additional information shown on the display 'Page Logging'. With the help of Oracle SQL Developer 1.5.5.
  
  Thank you!

  You could always give the current 2.1 ai2 test... continuous development may have fixed the issues in this area...

  Hope that helps,

• Where the SQL Scripts running after the installation of the ODAC for Oracle Client?

  I just installed ODAC for Oracle Client on a windows server that runs a database of sql server, allowing developers to connect to a web application to an Oracle/Unix database. The installation States to run SQL scripts, located in the $ORACLE_HOME\ASP.NET\SQL directory after installation. I don't know where to run them? On the ORACLE DB on the Unix server? If someone could let me know, I'd appreciate it. Thank you.

  You must run on the Oracle database server, but they are necessary only if you use Oracle for ASP.NET providers.

  If you just install the software, so you can use OLEDB with SQL Server linked server, for example, you don't need them. What do you need to run although if this is the case is the oramtsadmin.sql script that creates the objects used by the Oracle MTS Recovery Service (if you do not have these objects created on the database) that SQL Server uses a distributed transaction for Oracle connections I think.

  It will be useful,

• What is the integer equivalent of the t - sql in oracle?

  I heard that oracle is not an ' Integer ' for table structures.
  
  He took all my fields of integer type and makes them Number (10.0).
  
  When my program runs, it compares the result in full and fails... If I look at the value it says "1 d" which I assume means 1 decimal Typedonnees.
  I need to return an integer data type. I need to change the Number (10,0) number (10) or something else?

  number (10,0) is an integer type. How do you compare numbers? I suspect a problem of conversion of customer.

  Moreover, this forum is specifically for the SQL Developer tool. You can get more answers in the forum 'SQL and PL/SQL '.

• Are constants of body of the PL/SQL Package in the shared or private area

  Based on that it is not clear to me if body Package PL/SQL constants are stored in the shared or private area.
  
  http://docs.Oracle.com/CD/B28359_01/server.111/b28318/memory.htm
  
  "PL/SQL program units and the Shared Pool
  
  Oracle database treats PL/SQL program units (anonymous blocks, procedures, functions, packages and triggers in database) much the same way he treats the individual SQL statements. Oracle database allocates a shared area to hold the shape analyzed, compiled a program unit. Oracle database allocates a private space to hold values specific to the session who runs the program unit, including local, global and package variables (also known as the package is instantiated) and stamps of SQL execution. If more than one user is running the same program unit, a place unique and shared is used by all users, while each user runs a separate copy of his own private SQL area containing session-specific values.
  
  The individual SQL statements contained in a PL/SQL program unit are processed as described in the previous sections. Despite their origins within a PL/SQL program unit, these SQL statements use a shared area to hold their analysed representations and a private space for each session, who executes the statement. »
  
  
  I am also curious to know what are the differences in fine grain in a perspective of memory and performance (multisession) for the two examples below. One is more effective?

  end application_util;
  
  vs.
  
  Example 2.
  
  create or replace
  package body
  application_util
  as
  
  procedure process_xxx
  (
  )
  as
  
  c_create_metadata constant varchar2 (6000): =...
  
  Start
  ...
  end process_xxx;

  But I still have to ask because it seems still more particularly in example 1 that the constant can be attributed to the use that the actual value could be a pointer to a constant string value in a table of symbols or something related to the compilation unit. I'm always curious in a perspective of management of memory if there is a difference between the example 1 and example 2, and if one is better and why.

  The storage is real, references to this storage internal to the PL/SQL engine. And irrelevant to the PL/SQL programmer.

  This question is really a disagreement over the shape is better: example 1 or example 2. I prefer the 1 example, for readability, testability, etc., and so the question is where is the performance of the memory/differences and or is it just preference of developer.

  I agree with rp0428 - he raised a very important point that it is a problem of scope and nothing else.

  Basically is there any trade-off between using one shape on the other insofar as the performance and memory management?

  Not really. Most runtime engines release not just actual system memory when a variable is out of range. the malloc() calls are expensive. Free() calls are expensive (and are not always the result in usable free memory which can be malloc'ed again).

  Several execution engines use what is called a managed heap. A malloc is made of a new process when it is initialized. The heap memory / managed malloc'ed is adjacent. Pointer allocation of memory for this process is initially pointing to the base of the managed heap. As the process allocates / uses memory, the pointer is moved just advance in the managed heap, which indicates the HWM as such - the beginning of the 'free' memory in the heap. Allocation is sequential.

  Reset of your variable execution, or releasing your runtime object, does not reset the HWM as other objects/variables can still be used and located after this place in the bunch. In this case set him free memory by releasing / resetting the language variables does not restore the kernel memory.

  Memory management is a sophisticated process entirely processed by the engine running - and best left to the runtime engine. As you as a programmer do not explicitly control the memory management, it is not a good idea to try to write code that artificially attempt to use 'better' for the runtime engine memory management. The next version of the runtime of that aura of new features, optimizations and so on — and your interference in your code to get the "valorisation" of memory can happen just bite you not bad after an upgrade to execution.

  Regarding the performance aspect - variable initialization is dependent on scope. In order to have a global scope means a one-time initialization, whereas a private scope (created each call) is a multiple unit. If the first is a little faster than the latter.

  However, the performance differences are tiny - IMO too small to justify this as a valid consideration to spend in addition to the decision of functional design on what possibilities a variable or a constant need to have.

  Subprogramme Aliasing parameter with the parameters passed by reference

  When the compiler passes a real parameter by reference, the actual and formal parameters refer to the same memory location. Therefore, if the subroutine changes the value of the formal parameter, change immediately shows in the real setting.

  The compiler always happening IN reference parameters, but the aliasing resulting cause any problems, because the subprogrammes could not assign values to the PARAMETERS.

  PARAMETERS are passed by reference, so when you change the actual variable, you change even as a variable IN.
