SQL Developer is a free, open-source, cross-platform IDE for SQL, PL/SQL and the Oracle Database. It is developed by Oracle Corporation.
This tutorial will introduce you to SQL Developer and show how to use its features to connect to an Oracle database and perform basic tasks such as creating tables, inserting data and running queries.
The tutorial assumes that you have already installed SQL Developer on your machine. If not, please refer to this article: “How To Install Oracle SQL Developer On Linux”.

SQL Sample Database For SQL Developer
The SQL sample database for SQL developer is a collection of tables, views and data that can be used when learning how to work with SQL. The tables in the SQL sample database are designed to demonstrate the most commonly used features of SQL. These tables are created using Oracle 11g PL/SQL scripts and can be imported into any Oracle database. The basic purpose of this sample database is to provide an easy way for people who are new to SQL to learn how to use it effectively and efficiently.
The tables in this database are divided into two categories:
1) Tables which contain information about employees and their salaries. These tables include employee_id, salary, commission_pct, commission_yr, commission_qtr, commission_mth, hire_date and job_id.
2) Tables which contain information about vendors and their vendors names, addresses and phone numbers. These tables include vendor_id, vendor_name, vendor_address1, vendor_address2, vendor_city, vendor_state, vendor_zipcode and vendor_phone number
SQL Developer is a free tool for SQL database development and administration. It is provided with the Oracle database server, which allows users to run SQL statements and scripts against an Oracle database.
SQL Developer provides a graphical user interface (GUI) for working with SQL databases and managing data. Users can also use it to create, edit and run PL/SQL code.
The following are some of its key features:
Data import wizard — A wizard-based tool that helps you import data into an existing table or create a new table based on existing data in another database or file format. You can also use this tool to export data from a table into another file format (previously analyzed by the wizard).
SQL Query Builder — An interactive tool that helps you build simple queries quickly by providing predefined query templates based on common SQL commands. You can also save any query as a named query for future reuse.
Scripting — A scripting panel where you can write and execute scripts using SQL syntax directly in the panel, without having to enter individual statements manually at each step of execution like when using SQL*Plus; however, unlike when using SQL*Plus, there is no command line prompt available in SQL Developer’s scripting panel so it cannot be used to write
