Quickstart: Use [!INCLUDEname-sos] to connect and query data in Azure SQL Data Warehouse

This quickstart demonstrates how to use [!INCLUDEname-sos] to connect to Azure SQL data warehouse, and then use Transact-SQL statements to create, insert, and select data.

Prerequisites

To complete this quickstart, you need [!INCLUDEname-sos], and an Azure SQL data warehouse.

  • [Install [!INCLUDEname-sos]](download.md).

If you don't already have a SQL data warehouse, see Create a SQL Data Warehouse.

Remember the server name, and login credentials!

Connect to your data warehouse

Use [!INCLUDEname-sos] to establish a connection to your Azure SQL Data Warehouse server.

  1. The first time you run [!INCLUDEname-sos] the Connection page should open. If you don't see the Connection page, click Add Connection, or the New Connection icon in the SERVERS sidebar:

    New Connection Icon

  2. This article uses SQL Login, but Windows Authentication is also supported. Fill in the fields as follows using the server name, user name, and password for your Azure SQL server:

    Setting Suggested value Description
    Server name The fully qualified server name The name should be something like this: sqldwsample.database.windows.net
    Authentication SQL Login SQL Authentication is used in this tutorial.
    User name The server admin account This is the account that you specified when you created the server.
    Password (SQL Login) The password for your server admin account This is the password that you specified when you created the server.
    Save Password? Yes or No Select Yes if you do not want to enter the password each time.
    Database name leave blank The name of the database to which to connect.
    Server Group Select If you created a server group, you can set to a specific server group.

    New Connection Icon

  3. If your server doesn't have a firewall rule allowing Azure Data Studio to connect, the Create new firewall rule form opens. Complete the form to create a new firewall rule. For details, see Firewall rules.

    New firewall rule

  4. After successfully connecting your server opens in the Servers sidebar.

Create the tutorial data warehouse

  1. Right click on your server, in the object explorer and select New Query.

  2. Paste the following snippet into the query editor and click Run:

     IF NOT EXISTS (
    SELECT name
    FROM sys.databases
    WHERE name = N'TutorialDB'
 )
 CREATE DATABASE [TutorialDB] (EDITION = 'datawarehouse', SERVICE_OBJECTIVE='DW100');
 GO  
 
 ALTER DATABASE [TutorialDB] SET QUERY_STORE=ON
 GO

Create a table

The query editor is still connected to the master database, but we want to create a table in the TutorialDB database.

  1. Change the connection context to TutorialDB:

    Change context

  2. Paste the following snippet into the query editor and click Run:

    [!NOTE] You can append this to, or overwrite the previous query in the editor. Note that clicking Run executes only the query that is selected. If nothing is selected, clicking Run executes all queries in the editor.

    -- Create a new table called 'Customers' in schema 'dbo'
-- Drop the table if it already exists
IF OBJECT_ID('dbo.Customers', 'U') IS NOT NULL
DROP TABLE dbo.Customers
GO
-- Create the table in the specified schema
CREATE TABLE dbo.Customers
(
   CustomerId        INT     NOT NULL,
   Name      [NVARCHAR](50)  NOT NULL,
   Location  [NVARCHAR](50)  NOT NULL,
   Email     [NVARCHAR](50)  NOT NULL
);
GO

Insert rows

  1. Paste the following snippet into the query editor and click Run:

    -- Insert rows into table 'Customers'
INSERT INTO dbo.Customers
   ([CustomerId],[Name],[Location],[Email])
   SELECT 1, N'Orlando',N'Australia', N'' UNION ALL
   SELECT 2, N'Keith', N'India', N'keith0@adventure-works.com' UNION ALL
   SELECT 3, N'Donna', N'Germany', N'donna0@adventure-works.com' UNION ALL
   SELECT 4, N'Janet', N'United States', N'janet1@adventure-works.com'

View the result

  1. Paste the following snippet into the query editor and click Run:

    -- Select rows from table 'Customers'
SELECT * FROM dbo.Customers;

  2. The results of the query are displayed:

    Select results
