• Creation of a new database Oracle and Sql Developer

  Hello
  
  I am a newbie to Oracle and and a beginner not so Sql Server and Visual Studio.
  
  I am trying to learn Oracle on my local machine. I want to create a new Oracle database and start learning from here.
  
  I downloaded the Client Oracle sql developer and maker of data. Could someone please provide some guidance on how to create an Oracle database?
  
  From the responses, it seems that none of the articles I've mentioned actually creates a database. SQL Server provides a free download, also a developer version for a small fee. What specific Oracle product would be better to provide this type of service?
  
  Thank you
  Mark

  You can download the company for educational use via the OTN site. There is also the Express edition, which includes limits on the OTN site as well.

  Whatever it is, read the agreements to make sure that you use it properly.

• What is this new SQL Beta - 1z1 - 071 - 2 SQL - Oracle Database SQL 12 c

  Hello

  It's confusing.

  This looks like a 2nd review SQL for Oracle 12 c.

  What is this new SQL Beta - 1z1 - 071 - 2 SQL - Oracle Database SQL 12 c

  Can someone explain.

  Roger

  OK - I guess I should have held off a few hours before my previous answer.  I just got an email in the Certification of Oracle program manager. Now, I have inside information.

  1Z0-071 is a SQL new test and the role it plays is between that of the review of databases SQL and SQL Expert.  Specifically, unlike review of databases SQL, passing it will give proof of the OCA for people who spend. I don't know more than that yet.  The review details page is not available and if the subjects are currently a grey area for me.  I'll probably create a blog on the review, if I can get a few details about it.

• New to Oracle - interested in certification SQL

  The book is related to the exam 1z0-051. I'm not sure it's the best way to learn SQL from scratch. However, since once you know a little SQL book is useful, though sometimes, some might say t make sure that you get enough practice.

  However, it doesn't seem to be a book for Oracle SQL Fundamentals II, although I saw somewhere that it will be published before the end of the year?

  Don't worry in the short term. There is a review of SQL, you may want to consider longer term (1z0-047), but which is advanced. ISBN-13: 978 - 0071498500 probably apply the material (but does not focus on the review... maybe it's a good thing).

  Which is the best db Oracle. Download for Windows XP that I can put on more than one computer, it is better for my sql certification?

  Oracle is resource intensive; and more as it increases version numbers.

  10g XE [http://www.oracle.com/technology/products/database/xe/index.html] is perfect, EXCEPT that it is 10g 11g not and cannot indicate features of 11g but its greate from the manageability perspective.

  11 GR 1 material has a much higher footprint, but course has all the features.

  Unfortunately, it's a choice s one or the other. and historically the windows uninstaller can be an ightmare.

  I think that I must really be suggesting you look at virtualization - example: [http://www.virtualbox.org/] to run Oracle 10 g XE at first... but then again I am not sure if I'm over complicating things and have not tried it myself.

  Versions of the database newever and reviews using the SQL syntax that is no longer compatible with ansi standards more late especially in the use of the joins of tables in my humble OPINION.

  Can I take the exam SQL 9i or it is no longer used (can't seem to download from anywhere?)

  You can take the exam but its is no longer available for download. REF for example unable to download Oracle 9i database (any version)

  Can I take the exam at the Oracle headquarters or an authorized service center, without their own path?

  You can take in some centres of Pearson VIEW [http://pearsonvue.com/oracle/locate]. (1z0-051 can also be taken online).

• Dblink Oracle to sql server, multiple database on the same server sql under a dblink

  Hi, we managed to set up an Oracle dblink to sql server and retrieve data.

  The user of sql server have been using via dblink has access to multiple databases on the same sql server

  But the question is how in oracle (if possible) prepend you the SQL access to this?

  For example:

  Sqlserver_prod has the user sqlserver_user which seems to be set up as default database sqlserver_db1

  But we have select access to sqlserver_db2

  all work well as sqlserver_user

  Select * from table_fromdb1

  Select * from dbo.table_fromdb1

  Select * from sqlserver_db1.dbo.table_fromdb1

  as does

  Select * from sqlserver_db2.dbo.table_fromdb2

  more in Oracle

  Oracle_db a dblink sqlserver_prod. World connection sqlserver_user

  everything works fine

  Select * from 'table_fromdb1"@sqlserver_prod '.

  Select * from 'dbo '. "table_fromdb1"@sqlserver_prod

  But how to (if possible) access from oracle

  sqlserver_db2.dbo.table_fromdb2

  without having to create a new sqlserver_db2_user referenced in a new dblink

  If oracle for oracle would be

  Select * from remote_oracle_schema.table@remote_oracle_db

  Hello

  You cannot select a table in a different SQL * database server from that to which the gateway instance connects.
  As stated in the documentation-

  Oracle® database gateway

  11g Release 2 (11.2) for AIX 5 L Based Systems (64-bit), HP - UX

  Itanium, Solaris (SPARC 64-Bit), Linux x 86 operating system,

  and Linux x 86-64

  In the section.

  The example SQL Server multiple databases: Configuration of the modem router

  A separate instance of the gateway that is required for each SQL Server database. Each

  instance needs its own Gateway system ID (SID).

  You will need to create a new instance of the gateway for the SQL * Server DB2 as well as a link separate db.

• Convert a MySQL function in Oracle PL/SQL

  
  Hello

  I'm trying to transfer a MySQL database in Oracle 12 c, there are a number of functions that I need to convert since I am new to Oracle and PL/SQL in particular, I would really appreciate your help for the conversion:

  CREATE FUNCTION get_customer_balance()p_customer_id INT p_effective_date DATETIME() RETURNS DECIMAL()5,2( )
  DETERMINISTIC
  READS SQL DATA
  BEGIN
  
  DECLARE v_rentfees decimal PLACES ()5,2) ; #TAXES PAID to RENT VIDEOS INITIALLY
  DECLARE v_overfees INTEGER ; #LATE FEES FOR RENTALS PREREQUISITES
  DECLARE v_payments decimal PLACES ()5,2) ; #SUM OF PREVIOUSLY MADE PAYMENTS
  
  SELECT IFNULL (SUM(film. rental_rate ),0) INTO v_rentfees
  FROM film , inventory , rental
  WHERE film . film_id = inventory . film_id
  ET inventory . inventory_id = rental . inventory_id
  AND rental . rental_date <= p_effective_date
  AND rental . Customer_ID = p_customer_id ;
  
  SELECT IFNULL (SUM(IF((TO_DAYS(rental. return_date ) - TO_DAYS(rental. rental_date )) > film. rental_duration ,

  
  ((TO_DAYS(rental. return_date ) - TO_DAYS(rental. rental_date )) - film. rental_duration ),0)),0) INTO v_overfees

  OÙ payment . payment_date <= p_effective_date
  AND payment . Customer_ID = p_customer_id ;
  
  RETURN v_rentfees + v_overfees – v_payments ;
  END

  This means that rental.return_date and rental.rental_date are declared as a TIMESTAMP. Question is why? Return_date/rental_date store fractions of a second? In any case, assuming rental_duration is in days:

  WHEN rental.return_date - rental.rental_date > numtodsinterval (film.rental_duration, 'day')

  But the question is return_date and rental_date stores it part time too. I assumed that he didn't, and simply omitted TO_DAYS. If so, then TO_DAYS should be translated to TRUNC:

• Number of databases such as Oracle and SQL Server in the same application ADF

  Hello
  
  In my application, I need to use two different databases such as Oracle and SQL Server. There are screens that I need to develop in the ADF where I need to involve fields of the tables in these two different databases. I just want to know - is it possible to do so in application of the ADF?
  
  Or to create a sort of link between these databases in the backend? Then create a view object involving some distributed SQL queries. What can I do with this type of request than anything? I mean, can I use the two insert or update operation using this VO?
  
  Or y at - it another way to do this?
  
  Please help, help here would be really appreciated. I've been stuck with this problem for a while now. I did search our forums for the same problem, but was not able to find a reliable solution.
  
  Thank you
  Vijay

  It's still not clear to me if you need two db tables in a query, or a transaction.
  If this is the case, your best option (to my knowledge) is to use a db link. in this way, you only need to access (for example the oracle db) and can access the objects from the other data from the oracle database.
  I don't understand

  (3) a model project with a meeting of the two datasource. I selected a data source and created OT and VO. When I have selected a different data source and select tables to create VO and EO and finished but these EO and VO is displayed in project. >

• Need help to write to Oracle and SQL Server in the Oracle triggering

  We have a third which feeds data for us. Their client application feeds directly to some source tables in our Oracle database 10g. We have triggers on those tables that sort and treat lines as they come.
  
  We have a new operation and try to write some of these incoming data now to a SQL Server database through heterogeneous services - essentially the same exact data in two databases. I have a related database that works very well for the selection, but I've never tried to write Oracle PL/SQL to write in a DB SQL Server 2008. My first attempt was met with the following error: "ORA-02047: impossible to join the current distributed transaction.
  
  I found another thread where they say that the only way to do it is by using a stand-alone transaction, but they do not give an example. Here is the section of relaxation that I use:

    select to_char(new_date,'MM-DD-YYYY') into sql_txt from dual;
    insert into mancamp_location@sqlweb
         ("UnitID", "ManCampID", "Lat", "Long", "UpdateDT", "VehSpeed", "VehDirection", "Landmark")
      values (v_truck, f_unit, f_lat, f_long, sql_txt, f_spd, f_dir, f_ldmk);

  Can someone point me to a way to accomplish this simple insertion?

  An example of a standalone trigger is:

  Suppose you have a table in Oracle:

  CREATE TABLE emp_sal
  (
  EMPNO NUMBER 4,
  SAL NUMBER (7.2));

  and a similar table in a SQL server:
  SQL Server:

  CREATE TABLE emp_sal
  (
  EMPNO NUMERIC (4).
  SAL NUMERIC (7.2));

  Then, you can create an insert trigger that replicates the data:
  CREATE OR REPLACE TRIGGER dg4odbc_repl AFTER INSERT ON emp_sal
  FOR EACH LINE
  DECLARE
  PRAGMA AUTONOMOUS_TRANSACTION;
  BEGIN
  INSERT INTO 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB '.
  VALUES (: new.empno,: new.sal);
  COMMIT;
  END;
  /

  -Note the validation, otherwise risk of ORA-6519

  When you now insert a record into the Oracle database:
  insert into emp_sal values (1234, '1200,89');
  the trigger is activated and inserts the record in SQL Server:
  Select * from 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB;
  EMPNO, SAL
  ----- -------
  1234 1200.89

  It works fine when you post data insert, but as soon as restore you the insert only data Oracle will be cancelled - data will remain as long as the independent transaction dedicated to its SQL Server insert:

  insert into emp_sal values (1384, '1200,89');
  Rollback;
  Select * from emp_sal;
  EMPNO, SAL
  ----- -------
  1234 1200.89

  Select * from 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB;
  EMPNO, SAL
  ----- -------
  1234 1200.89
  1384 1200.89

  So I strongly recommend to use the DG4MSQL gateway which is able to participate in distributed transactions and allows validation/restore transactions.

  DG4ODBC lie on OTN (http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html-online check out the "See all" link for your favorite platform), cloud of delivery of software Oracle (https://edelivery.oracle.com/) or "My Oracle Support". My Oracle support welcomes the latest version 11.2.0.3. In My Oracle Support goto patches and updates, then search for 11.2.0.3 data set Patch 10404530patch: 11.2.0.3.0 PATCH SET for ORACLE database SERVER, choose your preferred platform and see the Readme which CD contains the gateway software.

• How to do? Need help for syntax - new syntax Oracle

  create or replace
  PROCEDURE "SP_SAMPLE_data" (AutoCAD in VARCHAR2) AS
  where_criteria tank (100);
  BEGIN
  
  
  If prodName = 'A' then
  I want to build the where criteria string as the 'product_name in ('iPod', 'iPad').

  where concatenated where_criteria here - do not know how to concatenate.
  
  END SP_SAMPLE_data;
  
  New Oracle PL/SQL syntax.
  
  Oracle 10 g 2

  You can try something like this

  create or replace procedure SP_SAMPLE_data (prodName in VARCHAR2) AS
     where_criteria char(100);
     sql_stmt varchar2(1000);
  BEGIN
     if prodName = 'A' then
        -- I want to build the where criteria string as "product_name in ('iPod','iPad')"
        where_criteria := 'product_name in (''iPod'',''iPad'')';
     else
        -- I want to build the where criteria string as
        -- "product_name = directly read from the passed variable(prodName)"
        where_criteria := 'product_name = '''||prodName||'''';
    end if;
  
    sql_stmt := 'select * from MySchema.MyTable'||where_criteria;
  
  END SP_SAMPLE_data;
  

  I added the variable SQL_STMT as I'm not sure what you want to do with SQL statement once it is created. Do you intend to run it in the procedure or pass it on to the calling environment? If you need to pass this return, specify SQL_STMT as the out parameter.

• convert to oracle pl/sql

  Hi all
  
  can - anybody know how convert transact sql from sql server to oracle pl/sql.is any them tool or whatever is available.
  
  Kind regards
  Ankur

  Frankly - it's all just stupid to convert T - SQL in PL/SQL.

  There are significant differences between these two. PL is a real procedural and declarative language. It has features of OBJECT-oriented programming. It is absolutely nothing like T - SQL.

  Oracle is also different from SQL-Server. There are conceptual major and fundamental differences. After all, why do you buy Oracle customers? Because it's just like SQL-Server? Or because it is not and is very different from SQL-Server?

  Oracle is a very poor imitation of SQL-Server. It has no sense to treat it as SQL-Server.

  And in this vein, it is meaningless to implement the fundamental concepts of the T - SQL and SQL-Server by converting in PL/SQL. The result will probably happen again worse than what he has done in SQL Server. He will not be able to scale. It will be difficult to maintain. It will not use the features of Oracle that puts a technically superior product of RDBMS of SQL Server to Oracle.

  It only converts SQL Oracle server. A ports. And this is refactoring and redesign to better utilize the features of Oracle. Another thing, how can you only achieve the perceived benefits and the benefits of the passage of the SQL for Oracle Server?

• That means 1z0-117 oracle 11g sql tuning now say it includes v12 addition v11

  Hello

  I did the 1z0-117 sql tuning review once.

  Not too far away.

  I studied under and turned off for a while.

  I anticipate taking in 1 month.

  However, I just noticed that the oracle site says 1z0-117 also said that v12 is also included for consideration:

  Oracle 11g sql tuning.

  It makes no sense at all.

  Roger

  However, I just noticed that the oracle site says 1z0-117 also said that v12 is also included for consideration:

  Oracle 11g sql tuning.

  Unless you are looking for something I'm not, what actually is the 1Z0-117 page says: "validated against: review has been validated against Oracle Database 11g Release 2 version 11.2.0.1.0 and database Oracle 12 c 12.1.0.1.0"

  What they actually mean by it is that someone went through all the issues and and asked the question "is still a relevant issue for the release of 12 c to Oracle?'." "  If they find issues that are not valid because of an update/change, then the question will be removed from review (or changed) so that someone who has used 12 c but not 11 g will not at a disadvantage.

• Hi I am new to Oracle forms and reports I want to know the differences between the Enter query mode and Normal mode?

  Hi I am new to Oracle forms and reports I want to know the differences between the Enter query mode and Normal mode?

  Welcome to Oracle Forms!  Out of curiosity, what do you mean by 'new '?  You are a student or new to an organization that uses Oracle Forms?  Or just play with Oracle Forms to learn something new?

  Let me start by saying that many of your questions designtime can answer by searching in the help of the constructor of the form library.  It's accessible, like most of the other products in the Builder menu > help.

  Regarding your question, ENTER QUERY mode, as the term implies, is when it is in a State where it is accept input for the execution of a query.  When in this mode, there are various restrictions.  Yet once, it will find more details in the Builder Help.  In this case, search help for these two subjects, "SYSTEM." MODE'and "built-ins comments that are not allowed in the input query Mode".  There are many other pages that contain information about the ENTER_QUERY method, but these two should help you get started.

  Normal mode, as its name implies, is when it is in a State of 'normal '.  Basically to do nothing in particular, but also not in ENTER QUERY mode.  In this State, you can move the shape, INSERT, UPDATE, DELETE, documents, etc..

  You will find additional information, as well as a lot of documentation on the product page of forms of OTN:

• Am new to oracle ADF, what JOBS prospect within 3 years?

  Am new to oracle ADF, what jobs prospect within 3 years in ADF, actually am a form oracle developer and I would like to know if oracle will be good learning and good in terms of career...

  You do not you ask this in the wrong place?

  The people here are biased for JDeveloper and ADF. From my point of view, the chances are great!

  Oracle has announced to do more or less everything with ADF. However, this will not mean that you as a developer of forms are without a chance.
