MySQL-> table using SQL Developer Oracle

Greetings,

Currently, I am a (student) temporary employee who is responsible for the migration of the MySQL database of a company to their new (gr 11, 2) Oracle database.

So far, I use SQL Developer, because I learned a few minor techniques with this application.

I have tried different methods for the migration, including those of the Oracle (Migration of MySQL) page

I however got no positive results with most of the methods.

-J' have established a connection to the MySQL database Oracle database aswell, within SQL Developer

Now, so far, I've copied manually (right click on the table, copy to Oracle) 90% of the tables from the MySQL to Oracle database successfully.

However, these tables contain only about 5% of the data. The problem is in the 2 tables that actually have a decent amount of records.

FOR INFO:

File 1: 75MB file .csv, ~150.000 records (individual records contain all select queries, where the size)

File 02:50 MB of files .csv, ~2.200.000 records

My previous attempts to use the same copy for Oracle option to right click on one of the two largest tables resulted in the following error:

The table of queries down. Message: java.io.IOException: IO error: socket read timed out

My first action to prevent this error has been to add a second file data to the current storage space, giving it 200M maxsize.

Okay it's coming, my real questions!

This could be a possible solution to avoid the error mentioned earlier to return?

What other issues are possible in case of failure?

Uses an external table to a faster and more effective method?

(The reason for which I have not yet tried external tables is because I had no SYS (TEM) privileges, so anything that requires privileges, I first have to discuss with my superior).

Any help is appreciated! Although my next answer is maybe not earlier that come Monday 17.

Welcome, Brent

Hello

I just discovered there is a csv Import Wizard in sqldeveloper also - don't know if you tried?

tables in the destination database (oracle) - right-click and choose Import data - this will bring you in a Wizard of csv.

However, I think that due to the volumes of data it may have similar problems.

sqlldr is probably your best choice - it's pretty simple once you find a decent example - it seems to cover the basics of ok - Oracle SQL Stuff (for example): SQL-Loader: the tutorial step by step - example 1 (CSV file)

See you soon,.

  • How to add a column to a specific location within a table using Sql developer.

    Hello

    I need to add a column to a table in a specific location, how to proceed?
    I tried following
    clicked on a right-> Edit table then I got a screen with all the columns in the table
    where move column up and down column options are disabled.
    can someone help me with this.


    Thank you
    Harry

    Its not supported. In the database to insert a column in a specific location, you must re-create the table and SQL Developer team have, decided quite rightly, it is a step away.

    Remember in connection with the database column order is not serious.

    This error usually indicates a corrupt repository of migration or a user privilege is missing.

    Also the migration of SQL Developer 2 and 1 repository is not compatible - so I would say to create a single repository user for each new version.
    It is a repository of sample for SQL Developer 2.x user:

    CREATE USER migration IDENTIFIED BY migration DEFAULT TABLESPACE users TEMPORARY TABLESPACE temp;

    GRANT CONNECT, RESOURCE, CREATE VIEW, CREATE A PUBLIC SYNONYM TO
    Migration WITH the ADMIN OPTION.

    GRANT ALTER ANY ROLE, ALTER ANY SEQUENCE, ALTER ANY TABLE, ALTER TABLESPACE, ALTER ANY TRIGGER, COMMENT ANY TABLE, CREATE ANY SEQUENCE, CREATE ANY TABLE, CREATE ANY TRIGGER, CREATE ROLE, CREATE TABLESPACE, CREATE USER, DROP ANY SEQUENCE, DROP ANY TABLE, DROP ANY TRIGGER, DROP TABLESPACE, DROP USER, DROP ANY ROLE, GRANT ANY ROLE, INSERT ANY TABLE, SELECT ANY TABLE UPDATE no matter WHAT TABLE OF migration;

    I try with model db (DB empty, just a single table), but the error is same. However, if I try to copy the acronym tabele from SQL Server to Oracle it works fine...

    I guess it's something with the configuration, but beacause I am new in Oracle still have no idea...

    Any help would be much appreciated

    I thank in advance

    Stefan

    Hello Stefan,

    did you create the repository Migration of your database to Oracle (Tools-> Migration-> repository management)?

    The SS2K5ALLPLATFORM package is usually created when you add the migration of the Oracle database repository and it contains the function StageCapture.

    So please make sure that you have created a repository of migration in an Oracle database and associate it with the first step of your migration.

  • Import Export using SQL Developer

    People

    I have 6 tables whose data must be exported from a database and imported into the other. The structure of the table constraints etc. is the same across both of the DB.

    Database is 11g. Average amount of data in tables 5 is 2.5million contain lines and 1 340million.

    Could you please suggest the best possible way to the export and import of data using SQL Developer. Developer SQL version 3.2.20.09

    There is an option in the 'View' tab in Developer SQL by using 'DBA' but do not have s/n of these patterns. I am well aware expdp and impdp operations but it is managed by another team that can cause delays both want to do it myself.

    Can we do expdp and impdp on SQL Developer without access s/n?

    All of the suggestions.

    Thank you

    Simple method would be to create external table Using the ORACLE_DATAPUMP Access Driver. Its neat and fast.

    Thanx

    Download the latest developer SQL on your PC. Enable your firewall rules accept connections from your PC to the database port (usually 1521 - Oracle, 3306 - MySQL).
    Establish a connection with your data (assuming that the privileges are sorted) and start the migration.
    Note: For MySQL, you will need to download third party connector (a quick Google and you'll find the download and installation instructions).

    You already have the URL for the migration.

    Of course, you'll want to change the types of data, etc. as needed.

    I assumed that the XML can contain several "" sections and that each section can contain several entries.

    Thus the XMLTABLE aliasing as 'x' gives information of XML, and supplies the data associated with the XMLTABLE with alias 'y' which gets the multiple authors, which itself section of the XMLTABLE with alias 'z' for each of the article_item.

  • Demonstrating the PL/SQL using SQL Developer functions

    Good afternoon

    I started writing some PL/SQL functions to replace some of the SQL I use most often.  Some very simple examples would be:

    create or replace function func_test (p_1 number) return number
    
    is
    
    x number;
    y number;
    
    begin
    
    
    x :=1;
    y :=2;
    
    
    return p_1 * x * y;
    
    
    end func_test;
    
    

    create or replace function func_test2 (p_1 varchar2) return varchar2
    
    
    is
    
    
    return_val varchar2(10);
    
    
    begin
    
    
    select p_1 into return_val from dual;
    
    
    return return_val;
    
    
    end func_test2;
    

    However, on my place of work that I have not been granted created function privileges again until I can show some examples, which is understandable.

    For the moment, without these privileges, is there a way I can build/test functions in principle locally using SQL Developer without the need to write functions in our database? I.e. can demonstrate meanings in SQL Developer, but devoid of envelope to create or syntax of replace?

    I hope that's not too vague.

    Thank you

    Hello

    The obvious solution is to get privileges.  If your employer wants to do you something, they give you the necessary privileges to do so.  It's silly for them to tell you to do something, but refuses to let you do.

    Otherwise, you can install Oracle on your own machine, as suggested above.  It's free and legitimate, if you only use it for learning and development.  Oracle Express Edition is very easy to install.

    As a last resort, you can write functions and procedures that are local to an anonymous block, like this:

    SET SERVEROUTPUT ON

    DECLARE
    Function func_test (p_1 number) return number
    is
    x number;
    number of y;
    Start
    x: = 1;
    y: = 2;
    return p_1 * x y;
    end func_test;
    BEGIN
    dbms_output.put_line (func_test (3))
    || '= func_test results.
    );
    END;
    /

    You can only call this kind of function of the anonymous block in which it is defined.

  • To use SQL Developer 4.0.1 (4.0.1.14.48) on the operation of Win7 32-bit; but no JDK provided with the 32-bit download?

    For some reason, my IT Department installed a 32-bit Win7 on a laptop capable of 64-bit (HP ProBook 6460 b).

    I want to download and use SQL Developer 4.0.1 but see there is no 32 - bit download of it delivered with a suitable JDK.

    What are my options here

    (1) anyone can provide a download link for the appropriate JDK, and then what I do with it? I can place it in the same folder as the SQL Developer? I don't have administrative rights on my laptop by the way...

    (2) can I ask my IT dept to reimage my machine with Win7 64 bit rather than the 32-bit Win7?

    Here are the specifications of my laptop. Because it seems to be able to address up to 16 GB of RAM, I suspect 32 bit Win7 was installed as the laptop has only 4G of RAM in it. And without having to address more than 4 GB of RAM, it was perhaps the deciding factor to install a 32-bit version on Win7. Frankly, had not realized, he had nothing, but a 64 bit version of Windows 7:

    What is the least disruptive option / path of least resistance here?

    http://h10010.www1.HP.com/wwpc/pscmisc/VAC/us/product_pdfs/HP_ProBook_6460b_Notebook_PC_Datasheet.PDF

    You must inform your IT Department, you want a 64 bit OS.

    Then tell them you want to double your RAM.

    Trust me on this one.

    If they say no, then ask them to install Java 32 bit 7 on your machine, and you'll be ready to go.

    What could be the reason for this error please notify.

    Thank you

    Don't know if it is related to your question, but you need a JDK 1.6 (Java SDK). What do you get in Help - about - Version?

  • A question about the Oracle SQL Developer Oracle instance connection

    Hi all

    I would be grateful if you could kindly give me a helping hand.

    Recently, I installed the Oracle 11 g on Linux (ubuntu 8.10) database. I not create startup scripts. So here's how I start the server: (my linux user name is "dariyoosh", but in order to start the server I have connection on the terminal shell as user 'oracle')
    dariyoosh@alborz:~$ su oracle
    Password: 
    oracle@alborz:/home/dariyoosh$ cd
    oracle@alborz:~$ ORACLE_SID=database01
    oracle@alborz:~$ . oraenv
    ORACLE_SID = [database01] ? 
    The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1 is /u01/app/oracle
    oracle@alborz:~$ sqlplus '/as sysdba'
    ...
    SQL> STARTUP NOMOUNT
    ORACLE instance started.
    ...
    SQL> ALTER DATABASE MOUNT;
    ...
    SQL> ALTER DATABASE OPEN;
    
    Database altered.
    Then I can work without any problems with my database and everything works pretty well. Today, I decided to install Oracle SQL Developer IDE as it makes it easier to modify the SQL code. My problem is that after reading the tutorial Oracle online, that I am still able to connect to my database. Firstly according to the method that I wrote, I have set up the Oracle instance. But then when I run Oracle SQL Developer I don't know what to choose for the user name and password? because since SQL * Plus shell as you can see I always write: "sqlplus 'virtue sysdba' and it does not prompt me for any password, I can access the database directly." Any idea? What password? What user name? for Oracle SQL Developer?

    Thanks in advance.

    When you connect "/ as sysdba", you actually connect as the user named SYS from the privileges of your operating system. SYS is the owner of the database and a privileged user. You really want to use this username for the day to day operations, but only for what can do only SYS. If you need a different user name. Several Oracle databases have a user named SCOTT who has a number of tables for use tutorial. By default, the password for SCOTT's "Tiger." You may also have other demo users, such as "HR". I admit that I forgot what is the password of the HR, but it doesn't really matter because SYS can change with this command:

    ALTER USER hr IDENTIFIED BY whateveryouwant;
    

    This command:

    SELECT USERNAME FROM ALL_USERS;
    

    lists all the users in your database. Understand that many of these users are there as owners of objects such as stored procedures and tables for Application Express, or TYPEs for Oracle Locator, not for general use. When you are ready to create your own objects, ask SYS create a username for them with

    CREATE USER myusername IDENTIFIED BY mypassword;
    

    and grant that user the privileges as necessary. You'll want to read before you get too far - I think that the developer of the Application Guide is a good starting point.

    As long as you have 'no listener', you can't wait to connect to the site of the developer SQL or any other LDAP client.
