The SQL Practice database is a collection of data stored in SQL Server. You can use this database to practice writing queries or learn more about the relational database model.

The practice database contains tables, views, and stored procedures that are used in many examples throughout this book. You can use these tables to test your knowledge as you learn how to write queries and create data access code.

If you have never worked with databases before, you might want to spend some time reading about their structure before going through the examples in this book. For example, see What is SQL? for an introduction to Structured Query Language (SQL), which is used in all relational databases.

Sample Database For SQL Practice

The SQL database for practice is a simple database with two tables: employees and products.

The employees table has three columns: id, name and department. The products table has four columns: id, name, type and price.

Database example 1: Employee Database Tables with Data

In this post, I will share with you a sample database for SQL practice. The database contains a product table, an employee table and a contact table.

Product Table:

The product table has the following columns:

Name – The name of the product

Description – Description of the product

Price – The price of the product in US dollars.

Employee Table:

The employee table has the following columns:

Name – Name of employee.

Position_ID – Employee position ID number, which is unique in this table. (i.e., no two employees can have the same position ID number)

Contact Table:

The contact table has the following columns:

Name_First – First name of contact person. This column is not nullable and must contain at least one value. (i.e., it is required)

Name_Last – Last name of contact person. This column is not nullable and must contain at least one value. (i.e., it is required)

SQL database is a collection of tables, rows, and columns. It stores data in an organized manner.

SQL Database is a cloud-based database service offered by Microsoft Azure. It supports multiple programming languages that allow you to develop applications using SQL Server features with minimal development work.

This article will give you an overview of different ways to create a SQL database in Azure SQL Database. We will also discuss creating databases using the Azure portal and through code.

Creating Databases Using the Azure Portal

You can create a database using the Azure portal in the following ways:

In the dashboard page, click New > Data + Analytics > SQL Database. In this section, select your subscription and region where you want to create your database. Click Create, provide a name for your database, select an availability set (optional), and then click Create again to create your database.

The database is the basic unit of SQL. You can create a table or view in the database, insert data into the table and retrieve data from the table.

SQLite is a relational database management system (RDBMS) contained in a small executable file. It’s often used for local/offline storage of data and for creating software prototypes.

It is released under the terms of the SQLite License, which is included in the distribution. The author encourages using it for testing and development, but not for production systems unless you’re prepared to take responsibility for supporting it yourself.[1]

The source code for SQLite is in the public domain and is thus free for use for any purpose, including commercial applications.

This is a sample database download. This is a sample employee database tables with data. In this example we have the product table in sql example, and employee table in sql example for practice online.

The following is a list of common SQL commands and how to use them:

Select command – Selects specific columns from the database

Insert command – Adds new records to the database

Delete command – Deletes records from the database

Update command – Updates existing records in the database

Create Table command – Creates new tables in the database

Drop Table command – Drops existing tables from the database

Here is a sample database download. The database contains a table named employee with the following data:

– ID : integer, primary key (primary key constraint)

– Name : varchar(50)

– Age : integer (0 – 120)

– Sex : char(1) (1 = male, 2 = female)

– Salary : float(10,2) (10 decimals, 2 decimal places.)

SQL Database Example

CREATE DATABASE MyDatabase;

USE MyDatabase;

CREATE TABLE Product (productId INT PRIMARY KEY, productName VARCHAR(255), price INT);

INSERT INTO Product VALUES (1, ‘Chai’, 20);

INSERT INTO Product VALUES (2, ‘Chang’, 15);

INSERT INTO Product VALUES (3, ‘Aniseed Syrup’, 10);

INSERT INTO Product VALUES (4, ‘Chef Anton’s Cajun Seasoning’, 45);

INSERT INTO Product VALUES (5, ‘Grandma’s Boysenberry Spread’, 25);

A sample database is a collection of sample data that can be used to test your SQL queries, or as a starting point for your own database.

A sample database can be used by anyone who wants to learn how to use SQL.

Employee table

EmployeeID – Int, NOT NULL PRIMARY KEY EmployeeID is the primary key for the employee table.

EmpName – Varchar(50), NOT NULL The EmpName column is a variable-length field that can store up to 50 characters.

EmpPosition – Varchar(50), NOT NULL The EmpPosition column is a variable-length field that can store up to 50 characters.

EmpAddress – Varchar(100), NOT NULL The EmpAddress column is a variable-length field that can store up to 100 characters.

EmpCity – Varchar(20), NOT NULL The EmpCity column is a variable-length field that can store up to 20 characters.

EmpState – Varchar(5), NOT NULL The EmpState column is a variable-length field that can store up to 5 characters.
