Azure SQL Database is a relational database-as-a service (DBaaS) in the Microsoft Cloud ("Azure"). In this tutorial, you learn how to use the Azure portal and SQL Server Management Studio (SSMS) to:
- Create a database in the Azure portal
- Set up a server-level firewall rule in the Azure portal
- Connect to the database with SSMS
- Create tables with SSMS
- Bulk load data with BCP
- Query that data with SSMS
- Restore the database to a previous point in time restore in the Azure portal
If you don't have an Azure subscription, create a free account before you begin.
To complete this tutorial, make sure you have installed:
Log in to the Azure portal
Log in to the Azure portal.
Create a blank SQL database
Follow these steps to create a blank SQL database.
Click the New button found on the upper left-hand corner of the Azure portal.
Select Databases from the New page, and select SQL Database from the Databases page.
Fill out the SQL Database form with the following information, as shown on the preceding image:
Setting Suggested value Description Database name mySampleDatabase For valid database names, see Database Identifiers. Subscription Your subscription For details about your subscriptions, see Subscriptions. Resource group myResourceGroup For valid resource group names, see Naming rules and restrictions. Select source Blank database Specifies that a blank database should be created.
Click Server to create and configure a new server for your new database. Fill out the New server form with the following information:
Setting Suggested value Description Server name Any globally unique name For valid server names, see Naming rules and restrictions. Server admin login Any valid name For valid login names, see Database Identifiers. Password Any valid password Your password must have at least 8 characters and must contain characters from three of the following categories: upper case characters, lower case characters, numbers, and non-alphanumeric characters. Location Any valid location For information about regions, see Azure Regions.
Click Pricing tier to specify the service tier and performance level for your new database. For this tutorial, select 20 DTUs and 250 GB of storage.
Select a collation for the blank database (for this tutorial, use the default value). For more information about collations, see Collations
Click Create to provision the database. Provisioning takes about a minute and a half to complete.
On the toolbar, click Notifications to monitor the deployment process.
Create a server-level firewall rule
The SQL Database service creates a firewall at the server-level that prevents external applications and tools from connecting to the server or any databases on the server unless a firewall rule is created to open the firewall for specific IP addresses. Follow these steps to create a SQL Database server-level firewall rule for your client's IP address and enable external connectivity through the SQL Database firewall for your IP address only.
SQL Database communicates over port 1433. If you are trying to connect from within a corporate network, outbound traffic over port 1433 may not be allowed by your network's firewall. If so, you cannot connect to your Azure SQL Database server unless your IT department opens port 1433.
After the deployment completes, click SQL databases from the left-hand menu and then click mySampleDatabase on the SQL databases page. The overview page for your database opens, showing you the fully qualified server name (such as mynewserver20170313.database.windows.net) and provides options for further configuration. Copy this fully qualified server name for use later.
You need this fully qualified server name to connect to your server and its databases in subsequent quick starts.
Click Set server firewall on the toolbar as shown in the previous image. The Firewall settings page for the SQL Database server opens.
Click Add client IP on the toolbar to add your current IP address to a new firewall rule. A firewall rule can open port 1433 for a single IP address or a range of IP addresses.
Click Save. A server-level firewall rule is created for your current IP address opening port 1433 on the logical server.
Click OK and then close the Firewall settings page.
You can now connect to the SQL Database server and its databases using SQL Server Management Studio or another tool of your choice from this IP address using the server admin account created previously.
By default, access through the SQL Database firewall is enabled for all Azure services. Click OFF on this page to disable for all Azure services.
SQL server connection information
Get the fully qualified server name for your Azure SQL Database server in the Azure portal. You use the fully qualified server name to connect to your server using SQL Server Management Studio.
- Log in to the Azure portal.
- Select SQL Databases from the left-hand menu, and click your database on the SQL databases page.
In the Essentials pane in the Azure portal page for your database, locate and then copy the Server name.
Connect to the database with SSMS
Use SQL Server Management Studio to establish a connection to your Azure SQL Database server.
Open SQL Server Management Studio.
In the Connect to Server dialog box, enter the following information:
Setting Suggested value Description Server type Database engine This value is required Server name The fully qualified server name The name should be something like this: mynewserver20170313.database.windows.net. Authentication SQL Server Authentication SQL Authentication is the only authentication type that we have configured in this tutorial. Login The server admin account This is the account that you specified when you created the server. Password The password for your server admin account This is the password that you specified when you created the server.
Click Options in the Connect to server dialog box. In the Connect to database section, enter mySampleDatabase to connect to this database.
Click Connect. The Object Explorer window opens in SSMS.
In Object Explorer, expand Databases and then expand mySampleDatabase to view the objects in the sample database.
Create tables in the database
Create a database schema with four tables that model a student management system for universities using Transact-SQL:
- Credit that model a student management system for universities
The following diagram shows how these tables are related to each other. Some of these tables reference columns in other tables. For example, the Student table references the PersonId column of the Person table. Study the diagram to understand how the tables in this tutorial are related to one another. For an in-depth look at how to create effective database tables, see Create effective database tables. For information about choosing data types, see Data types.
You can also use the table designer in SQL Server Management Studio to create and design your tables.
In Object Explorer, right-click mySampleDatabase and click New Query. A blank query window opens that is connected to your database.
In the query window, execute the following query to create four tables in your database:
-- Create Person table CREATE TABLE Person ( PersonId INT IDENTITY PRIMARY KEY, FirstName NVARCHAR(128) NOT NULL, MiddelInitial NVARCHAR(10), LastName NVARCHAR(128) NOT NULL, DateOfBirth DATE NOT NULL ) -- Create Student table CREATE TABLE Student ( StudentId INT IDENTITY PRIMARY KEY, PersonId INT REFERENCES Person (PersonId), Email NVARCHAR(256) ) -- Create Course table CREATE TABLE Course ( CourseId INT IDENTITY PRIMARY KEY, Name NVARCHAR(50) NOT NULL, Teacher NVARCHAR(256) NOT NULL ) -- Create Credit table CREATE TABLE Credit ( StudentId INT REFERENCES Student (StudentId), CourseId INT REFERENCES Course (CourseId), Grade DECIMAL(5,2) CHECK (Grade <= 100.00), Attempt TINYINT, CONSTRAINT [UQ_studentgrades] UNIQUE CLUSTERED ( StudentId, CourseId, Grade, Attempt ) )
Expand the 'tables' node in the SQL Server Management Studio Object explorer to see the tables you created.
Load data into the tables
Create a folder called SampleTableData in your Downloads folder to store sample data for your database.
Right-click the following links and save them into the SampleTableData folder.
Open a command prompt window and navigate to the SampleTableData folder.
Execute the following commands to insert sample data into the tables replacing the values for ServerName, DatabaseName, UserName, and Password with the values for your environment.
bcp Course in SampleCourseData -S <ServerName>.database.windows.net -d <DatabaseName> -U <Username> -P <password> -q -c -t "," bcp Person in SamplePersonData -S <ServerName>.database.windows.net -d <DatabaseName> -U <Username> -P <password> -q -c -t "," bcp Student in SampleStudentData -S <ServerName>.database.windows.net -d <DatabaseName> -U <Username> -P <password> -q -c -t "," bcp Credit in SampleCreditData -S <ServerName>.database.windows.net -d <DatabaseName> -U <Username> -P <password> -q -c -t ","
You have now loaded sample data into the tables you created earlier.
Execute the following queries to retrieve information from the database tables. See Writing SQL Queries to learn more about writing SQL queries. The first query joins all four tables to find all the students taught by 'Dominick Pope' who have a grade higher than 75% in his class. The second query joins all four tables and finds all courses in which 'Noe Coleman' has ever enrolled.
In a SQL Server Management Studio query window, execute the following query:
-- Find the students taught by Dominick Pope who have a grade higher than 75% SELECT person.FirstName, person.LastName, course.Name, credit.Grade FROM Person AS person INNER JOIN Student AS student ON person.PersonId = student.PersonId INNER JOIN Credit AS credit ON student.StudentId = credit.StudentId INNER JOIN Course AS course ON credit.CourseId = course.courseId WHERE course.Teacher = 'Dominick Pope' AND Grade > 75
In a SQL Server Management Studio query window, execute following query:
-- Find all the courses in which Noe Coleman has ever enrolled SELECT course.Name, course.Teacher, credit.Grade FROM Course AS course INNER JOIN Credit AS credit ON credit.CourseId = course.CourseId INNER JOIN Student AS student ON student.StudentId = credit.StudentId INNER JOIN Person AS person ON person.PersonId = student.PersonId WHERE person.FirstName = 'Noe' AND person.LastName = 'Coleman'
Restore a database to a previous point in time
Imagine you have accidentally deleted a table. This is something you cannot easily recover from. Azure SQL Database allows you to go back to any point in time in the last up to 35 days and restore this point in time to a new database. You can you this database to recover your deleted data. The following steps restore the sample database to a point before the tables were added.
On the SQL Database page for your database, click Restore on the toolbar. The Restore page opens.
Fill out the Restore form with the required information:
- Database name: Provide a database name
- Point-in-time: Select the Point-in-time tab on the Restore form
- Restore point: Select a time that occurs before the database was changed
- Target server: You cannot change this value when restoring a database
- Elastic database pool: Select None
- Pricing tier: Select 20 DTUs and 250 GB of storage.
Click OK to restore the database to restore to a point in time before the tables were added. Restoring a database to a different point in time creates a duplicate database in the same server as the original database as of the point in time you specify, as long as it is within the retention period for your service tier.
In this tutorial, you learned basic database tasks such as create a database and tables, load and query data, and restore the database to a previous point in time. You learned how to:
