Oracle Sql Developer High Quality Download Tutorial
Leigh Mccowin
Developed in Java, SQL Developer runs on Windows, Linux and the Mac OS X. This is a great advantage to the increasing number of developers using alternative platforms. Multiple platform support also means that users can install SQL Developer on the Database Server and connect remotely from their desktops, thus avoiding client server network traffic.
In this tutorial, you will use SQL Developer to create objects for a simplified library database, which will include tables for books, patrons (people who have library cards), and transactions (checking a book out, returning a book, and so on).
Many other SQL Developer tutorials are available. For information, see the Start Page (click Help, then Start Page, then the Get Started tab if it is not already visible), especially the Tutorials and Online Demonstrations.
The tables are deliberately oversimplified for this tutorial. They would not be adequate for any actual public or organizational library. For example, this library contains only books (not magazines, journals, or other document formats), and it can contain no more than one copy of any book.
To create the BOOKS table, connect to the database as the user in the schema you want to use for this tutorial. Right-click the Tables node in the schema hierarchy on the left side, select New Table, and enter the following information. (If a tab or field is not mentioned, do not enter anything for it. Be sure that the Advanced box is not checked when you start creating the table.)
To create the PATRONS table, if you are not already connected, connect to the database as the user for the schema you are using for this tutorial. Right-click the Tables node in the schema hierarchy on the left side, select New Table, and enter the following information. (If a tab or field is not mentioned, do not enter anything for it. Be sure that the Advanced box is not checked when you start creating the table.)
To create the TRANSACTIONS table, if you are not already connected, connect to the database as the user for the schema you are using for this tutorial. Right-click the Tables node in the schema hierarchy on the left side, select New Table, and enter the following information. (If a tab or field is not mentioned, do not enter anything for it. Be sure that the Advanced box is not checked when you start creating the table.)
To create the sequence, if you are not already connected, connect to the database as the user for the schema you are using for this tutorial. Right-click the Sequences node in the schema hierarchy on the left side, select New Sequence, and enter information using the Create Sequence dialog box.
For your convenience in using the view and the PL/SQL procedure that you will create, add some sample data to the BOOKS, PATRONS, and TRANSACTIONS tables. (If you do not add sample data, you can still create the remaining objects in this tutorial, but the view and the procedure will not return any results.)
To create the patrons_trans_view view, if you are not already connected, connect to the database as the user for the schema you are using for this tutorial. Right-click the Views node in the schema hierarchy on the left side, select New View, and enter the following information. (If a tab or field is not mentioned, do not enter anything for it.)
To create the procedure, if you are not already connected, connect to the database as the user for the schema you are using for this tutorial. Right-click the Procedures node in the schema hierarchy on the left side, select New Procedure, and enter the following information using the Create PL/SQL Procedure dialog box.
To create this procedure, if you are not already connected, connect to the database as the user for the schema you are using for this tutorial. Right-click the Procedures node in the schema hierarchy on the left side, select New Procedure, and enter the following information using the Create PL/SQL Procedure dialog box.
You can use the SQL Worksheet to test SQL statements using a database connection. To display the worksheet, from the Tools menu, select SQL Worksheet. In the Select Connection dialog box, select the database connection that you used to create the BOOKS, PATRONS, and TRANSACTIONS tables for the tutorial.
The following statements create and use the database objects that you have created (or will create) for the tutorial in SQL Developer Tutorial: Creating Objects for a Small Database. You can view these commands to help you understand the library database objects that are covered in the tutorial.
The next section of this tutorial covers downloading and installing SQL Developer. If you already have SQL Developer downloaded and installed, you may wish to skip ahead to the next page to learn how to create a new database connection.
Towards the end of this tutorial, there are a few pages that cover how to write, run and save SQL statements, how to export data using SQL Developer and how to import data into Oracle using SQL Developer. You may also be interested in using SQL Developer to reverse engineer an Oracle schema. That tutorial is linked here.
As you go through the entire tutorial series, you will acquire a lot of new knowledge about PL/SQL programming. These PL/SQL tutorial series present the best practices in PL/SQL programming language. The best part is that each tutorial contains a lot of examples and helpful scripts.
In SQL Developer 3.0, the DBA Navigator is a new feature. This tutorial focuses on several of the DBA Navigator features, including database usage, intialization parameters, auditing, roles, privileges, and storage information.
I am new to SAS and so far I have always used Sqldeveloper from Oracle, could someone tell me pros and cons of each or differences. In SAS we have libraries that target each bbdd and we have detected some disadvantages like:
Our Oracle tutorial includes all topics of Oracle database such as insert record, update record, delete record, select record, create table, drop table etc. There are also given Oracle interview questions to help you better understand the Oracle database.
PL/SQL is a combination of SQL along with the procedural features of programming languages. It was developed by Oracle Corporation in the early 90's to enhance the capabilities of SQL. PL/SQL is one of three key programming languages embedded in the Oracle Database, along with SQL itself and Java. This tutorial will give you great understanding on PL/SQL to proceed with Oracle database and other advanced RDBMS concepts.
This tutorial is designed for Software Professionals, who are willing to learn PL/SQL Programming Language in simple and easy steps. This tutorial will give you great understanding on PL/SQL Programming concepts, and after completing this tutorial, you will be at an intermediate level of expertise from where you can take yourself to a higher level of expertise.
Before proceeding with this tutorial, you should have a basic understanding of software basic concepts like what is database, source code, text editor and execution of programs, etc. If you already have an understanding on SQL and other computer programming language, then it will be an added advantage to proceed.
This tutorial is an introduction to using Python with Oracle Database. It contains beginner and advanced material. Sections can be done in any order. Choose the content that interests you and your skill level. The tutorial has scripts to run and modify, and has suggested solutions.
If you need to create a new user, review the grants created in samples/tutorial/sql/create_user.sql. Then open a terminal window, change to the samples/tutorial/sql directory, and run the create_user.sql script as the SYSTEM user, for example:

SQL Developer is a free Database IDE that allows you to interact with databases using a graphical user interface instead of command-line tools like Db2 command line or Db2 command line plus. In the past, SQL Developer solely supported Oracle Database. However, by using third party plugins, you can use SQL developer to work with other database systems such as MySQL, SQL Server, or IBM Db2.
There are many ways to access Postgres databases. Many database designers, developers and administrators use IDEs (Integrated Development Environment) as tools to access the internals of their database estate.
In this PL/SQL Tutorial, you will learn basic introduction to PL/SQL and basic concepts like structure, syntax, etc. Moreover in the advanced stuff in this PL/SQL tutorial in Oracle, you will learn Data types, variables, collections, Loops, stored procedure, exception handling, packages, triggers, and so on.
This Oracle PL/SQL Tutorial is specially designed for the Software Professionals who are interested to learn PL SQL. This PL SQL tutorial will help you learn PL/SQL programming in a simple and easy way and will help you to understand all the PL/SQL concepts.
