SQL server - get list of active connections to each database
Many times, we want list of all users who are connected to the SQL server - to determine it  use the below query. It returns the Database, Number of open connections and logged-in user credentials.

SELECT DB_NAME(dbid) as Database, COUNT(dbid) as Number Of Open Connections,
loginame as LoginName
FROM sys.sysprocesses
WHERE dbid > 0
GROUP BY dbid, loginame

Hope this helps.

Thanks a lot for this.

At least in my version of MSSQL, Database is a keyword. You can't use it as a column name unless you put it in quotes.

Thanks. Very useful. I had to put brackets or double quotes around the field name aliases to get them to work properly.

Examples:
SELECT DB_NAME(dbid) as [Database]
or
SELECT DB_NAME(dbid) as "Database"

loginame as LoginName

Is there a way to determine if they are valid? I have found that a machine that loses connectivity (unplugged cable in test) leaves a connection for hours.

Very new to this!! What is "dbid"? Is this where I put in the name of my database? Or do I replace "DB_NAME" with the name of my database? Or, is there no need for the name of mine to be in here?

Here is good list of the important components of SQL server. People who are learning SQL server must understand and use of these components while creating connection to make a app, software or a website. Well! I want rushmyessay but this is reliable site to learn the basic points about programming.
