The following example finds the users that are connected to the server and returns the number of sessions for each user. The following example finds the cursors that have been open for more than a specific period of time, who created the cursors, and what session the cursors are on.
The following example finds sessions that have open transactions and are idle. An idle session is one that has no request currently running.

At this point, there are plenty of ways in SQL to find out, in detail, which users are active, and what they are up to. How many users are on your databases? Well, there could be just one user login doing one heck of a lot, using many sessions. This is especially true if you have a shared connection to the application under one User ID, so that there are many people or processes using one login name.
The better your security, the more users you are likely to have in proportion to the sessions, because it means that users are not sharing logins. We therefore need to track SPIDs and logins. Listing 1 shows a quick query to tell you how many sessions are being used by each login name on each database on a server. Then, we can investigate further using queries such as those above. There is usually, but not always, a relationship between connections and sessions.
At the database level, the built-in Active Transactions metric gives us only currently running transactions; it will miss reads and will probably include lots of system transactions. What we want instead is a database-level metric telling us how many sessions have been actively reading or writing over a recent period. You can also modify additional connection options by selecting Options.
Examples of connection options are the database you're connecting to, the connection timeout value, and the network protocol. This article uses the default values for all the fields. To verify that your SQL Server connection succeeded, expand and explore the objects within Object Explorer where the server name, the SQL Server version, and the username are displayed. These objects are different depending on the server type. After the query is complete, the new TutorialDB database appears in the list of databases in Object Explorer.
If it isn't displayed, right-click the Databases node, and then select Refresh. In this section, you create a table in the newly created TutorialDB database. Because the query editor is still in the context of the master database, switch the connection context to the TutorialDB database by doing the following steps:.
It's great you're an active member here on SF, but perhaps you should ask which training materials would best assist you in learning SQL ? That isn't a good fit for stack's format You can make a book suggestion if you have one. SteveC is free to ask as many questions as he needs. I didn't look at the date. Have a nice day. Learning through reading reference material is a great way to learn for some people. I've struggled throughout my life with concentration issues and have put in many thousands of hours and have decided I'm stupid or lazy.
