SQL University: Basic Tools Pt. II

In Tuesday’s class we covered the different authentication methods as well as did a quick walk-through of the SQL Management Studio interface. In today’s lecture we’ll continue looking at SSMS. Some of the things we look at include how to create a query against a database, brief intro to the Profiler tool as well as a brief intro to the Database Engine Tuning Advisor.

In addition to watching the video you guys have a little bit of homework. Don’t worry, it’s not hard. Just try a few of the things on this list to help you get accustomed to the environment.

  • Connect to your local database using SSMS using Windows authentication
  • Browse to the AdventureWorks Database, Open up the Tables folder and select the TOP 1000 Rows from Person.Address table. In comments below, post the AddressLine1 for AddressID 17.
  • [Extra Credit] Browse to the Security folder, Open up the Logins folder. Create a new login called testlogin. Make it SQL Server authentication, give it password of ‘P@$$w0rd’ (NOTE: Thanks to Brian Kelley for pointing this out. Do NOT use your production servers/databases for this excercise. Also NEVER use password this simple in your production environment…ever. Security will be covered in a few weeks.), make its default database AdventureWorks.

Next week we’ll be covering Backup and Restore with Argenis Fernandez (Blog | Twitter). The full syllabus for the semester will be posted shortly.

SQL University: Basic Tools

Welcome to the first day of SQL University. Today we’re going to be talking about basic tools you’ll be using as a database administrator (DBA).

Throughout our lessons you will notice I will be linking heavily to SQL Server Books Online. Books Online is the official documentation for all things SQL Server. This is important to know as many administrators and developers refer to this documentation on a daily basis as well as in everyday conversation. You can access Books Online in one of two ways. One is directly via the website on MSDN or you can actually download Books Online (Click to Download Latest as of 9/23/09) so that you can access and refer to the documentation even when no network access is available. While downloading it for offline use can be beneficial (and portable) be aware that Microsoft does update Books Online with new information which means you would have to download and install the latest version of Books Online when this occurs. The good news is that when you use the local version of Books Online it does ask you up front if you want to use the internet as the first point of reference. Another advantage of having Books Online locally installed is that you can bookmark topics and searches so you can save time if you find yourself referring to a certain topic (which I can almost guarantee you will!). That being said make sure you explore the various links given to fully get the most out of the content delivered here at SQL U.

The most basic tool in the SQL Server toolset for an administrator or developer is a management graphical interface called the SQL Server Management Studio (SSMS). SSMS is where you can access, configure, manage and administrate your servers. The following video walks you through the basics of SSMS so you can become familiar with it. Before you watch the video there are a few things you need to know about SQL Server.

Authentication

In order to connect to a server or database you need to provide it valid credentials. This method is referred to as authentication. SQL Server recognizes two different types of authentication: Windows authentication and SQL Server Authentication. Windows authentication (sometimes also referred to as Integrated Security)  is when you provide SQL Server Windows account credentials. This can be either a Windows domain account (i.e. domainusername) or a local Windows account (i.e. local-machineusername). By default Windows authentication is the default authentication method selected when you open SSMS, and of note, is also more secure. We’ll get in to the hows and whys of that in another class. When you open SSMS, the Windows credentials for the account you are logged into the machine as will automatically pass to SSMS. For instance if I’m logged into my computer as a user called JSEGARRA, that is on a domain called MSDOMAIN, SSMS will open and you will see in the box for username (will be greyed out) MSDOMAINJSEGARRA.

The second method of authentication is SQL Server Authentication (sometimes also referred to as just SQL Authentication). This method of authentication is useful for instances that, for whatever reason, do not have access to a Windows domain account or just a domain in general. SQL accounts are created and kept within the database instance itself.  An example of a use for this type of authentication method would be a database server that resides outside of a company firewall so that the public needs to get to it. Typically these servers are kept in what’s called the DMZ (demilitarized zone), which is an area that belongs to the company but is segregated from the internal network for security reasons. Since the DMZ is outside of the normal network you wouldn’t be able to authenticate with a domain account so instead we use local credentials like a SQL account.

Best of Both Worlds

For those curious, yes you CAN have both Windows authentication and SQL authentication enabled on your database server. This mode is called Mixed mode since you’re mixing both types of authentication methods. Be aware, however, that this increases your attack surface as you’re opening more holes to access your database server. Microsoft best practices recommend using Windows authentication for security reasons (account is managed at domain level, leverage AD groups, etc.).
