For an instructor lead, in-depth look at learning SQL click below.
Microsoft Azure SQL Database (often named Azure SQL) is a managed cloud database provided as part of Microsoft’s Azure Services. It shares a common code base with Microsoft SQL Server and presents a complete platform for managing relational databases for both small and large businesses. In this blog post, I will take you through the basic understanding of Microsoft Azure SQL Database and we will explore some practical SQL code examples.
What is Azure SQL?
Azure SQL is a cloud-based service built on the robust SQL Server Database Engine and provides a scalable database platform with advanced security features. This service enables you to focus on the design and implementation of your applications without having to maintain the underlying infrastructure.
Basic Azure SQL Operations
Here are the basic Azure SQL operations that every SQL programmer needs to know:
1. Creating a Database
Creating a new database in Azure SQL is quite simple. You just need to use the CREATE DATABASE statement as shown below:
|
1 2 3 |
CREATE DATABASE SampleDB; |
This statement creates a new database named ‘SampleDB’.
2. Inserting Data
Inserting data into a Azure SQL database is accomplished using the INSERT INTO statement. For example:
|
1 2 3 4 |
INSERT INTO Employees (FirstName, LastName, Email) VALUES ('John', 'Doe', <a href="mailto:'johndoe@example.com'" >'johndoe@example.com'</a>); |
This statement inserts a new record into the ‘Employees’ table.
3. Retrieving Data
To retrieve data from the database you can use the SELECT statement. For example:
|
1 2 3 |
SELECT * FROM Employees; |
This statement retrieves all records from the ‘Employees’ table.
4. Updating Data
Data in the Azure SQL database can be updated using the UPDATE statement. For example:
|
1 2 3 4 5 |
UPDATE Employees SET Email = <a href="mailto:'new_email@example.com'" >'new_email@example.com'</a> WHERE FirstName = 'John' AND LastName = 'Doe'; |
This statement updates the email address of the employee named ‘John Doe’.
5. Deleting Data
To remove records from the database, the DELETE statement is used. For example:
|
1 2 3 4 |
DELETE FROM Employees WHERE FirstName = 'John' AND LastName = 'Doe'; |
This statement deletes the record of the employee named ‘John Doe’.
Conclusion
This is a brief introduction to the Microsoft Azure SQL Database. There’s much more to explore and learn. With hands-on practice, you can master the capabilities of this powerful cloud-based platform. Happy coding!
