trova il numero di connessione aperta sul database

Questo mostra il numero di connessioni per ogni DB:

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

E questo dà connessioni totali:

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