推荐答案

这显示了每个 DB 的连接数:

This shows the number of connections per each DB:

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

这给出了总数:

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0

如果您需要更多详细信息，请运行:

If you need more detail, run:

sp_who2 'Active'

注意:使用的 SQL Server 帐户需要 'sysadmin' 角色(否则它只会显示单行和 1 作为结果)

Note: The SQL Server account used needs the 'sysadmin' role (otherwise it will just show a single row and a count of 1 as the result)
