SQL stands for Structured Query Language and is designed for the retrieval and management of data in a relational database. It is a special-purpose programming language for expressing queries, statements and commands to be processed by database systems.
As a database administrator (DBA), you will often find yourself searching through your SQL database to find certain pieces of information. In this article, we’ll take a look at some sample SQL queries, so that you can get familiar with what they look like and how they work.
Sample Database For Practice SQL
SQL Server is a relational database management system developed by Microsoft. SQL Server databases can be created, accessed and managed using Microsoft SQL Server Management Studio. The following are some sample databases that can be used to practice SQL queries.

Sample SQL Database for Practice Online
The following is a sample database for practice online. You can use the following databases to practice writing queries and learn about relational database concepts.
The following table lists the employee tables from the sample database. The first table contains information about employees, and the next two tables contain information about their departments and their boss’s name:
Table Name Columns Type
emp_id int (identity) Primary Key, Not Null PRIMARY KEY
emp_name varchar(50) Primary Key, Not Null PRIMARY KEY
emp_salary money Primary Key, Not Null PRIMARY KEY
dept_id int (identity) Foreign Key (to dept_id) in dept_table
dept_name varchar(50) Foreign Key (to dept_name) in dept_table
boss_id int Foreign Key (to boss_id) in boss_table
SQL is a programming language used to create and manage databases. SQL stands for Structured Query Language, and it is used to communicate with databases.
This article provides a list of sample SQL database tables with data that you can use for free in your practice. You can use this database as an example when learning SQL or demonstrating how to query a database to others.
If you don’t have access to the sample database below, then you can download some free sample SQL databases with million records from here.
Some of the sample tables below are: employee, customer, product and store. These tables contain both numeric and character fields that have been populated with data. The samples also contain foreign keys between them as well as indexes on various fields.
The following sample SQL database is a good starting point for practicing the skills you learn in this course. The table and data were created using Microsoft SQL Server Management Studio.
The database contains a single table named employees. It has two columns: employee_id, which uniquely identifies each employee, and first_name, which contains each employee’s first name.
The data in this table was generated using the following statement:
INSERT INTO employees (first_name) VALUES (‘John’);
INSERT INTO employees (first_name) VALUES (‘Mary’);
INSERT INTO employees (first_name) VALUES (‘Bob’);

The SQL Server database is the most common database used by software developers. Many of the modern programming languages have built-in support for SQL Server, making it easy to access data from your applications.
The following are some tips to help you get started using SQL Server:
1) Downloading SQL Server Express: For those who don’t want to pay for a full version of SQL Server but still want to use the product, Microsoft offers a free download called SQL Server Express Edition that is limited in features and size. You can download this version at http://msdn.microsoft.com/en-us/sqlserver/bb980928.aspx
2) Installing SQL Server Express on Windows: The process of installing SQL Server depends on whether you’re using Windows 7 or Windows 8/8.1. If you’re using Windows 7, follow these steps:
a) Go to http://msdn.microsoft.com/en-us/sqlserver/bb980928.aspx and click Download under “SQL Server 2008 R2” (or whichever

SQL Server
SQL Server is a relational database management system developed by Microsoft. It is a powerful tool for storing structured data and accessing it quickly. SQL Server is available in many different editions, but the most commonly used are the Express, Standard and Enterprise editions.
SQL Server databases are made up of tables that contain rows, columns and data. The rows represent records (or “facts”) and columns represent fields (or “attributes”). For example, a simple table might contain customer names and addresses in one table row. A more complex table could include many rows with multiple columns for each customer.
A database can be stored on one computer or distributed across several computers connected by a network. Once you have created your database, you can use SQL Server Management Studio (SSMS) to create queries that retrieve data from the database tables. You can also use SSMS to add new tables or modify existing ones as needed.
