SQLDBA - SQL query to retrieve detailed information about active sessions in SQL Server.

 Here is a SQL query to retrieve detailed information about active sessions in SQL Server. This query provides insights into session details, including session ID, login name, database name, status, and more:

Sql
SELECT 
    s.session_id,
    s.login_name,
    s.host_name,
    s.program_name,
    s.status,
    s.cpu_time,
    s.memory_usage,
    s.total_elapsed_time,
    r.database_id,
    DB_NAME(r.database_id) AS database_name,
    r.command,
    r.wait_type,
    r.wait_time,
    r.blocking_session_id
FROM 
    sys.dm_exec_sessions s
JOIN 
    sys.dm_exec_requests r
ON 
    s.session_id = r.session_id
WHERE 
    s.is_user_process = 1; -- Filters only user sessions

Explanation:

• sys.dm_exec_sessions: Provides information about all active sessions.
• sys.dm_exec_requests: Provides details about requests currently executing.
• JOIN: Combines session and request data for detailed insights.
• WHERE s.is_user_process = 1: Filters out system sessions, showing only user-initiated sessions.

This query is adaptable and can be modified to include additional columns or filters based on your specific requirements.
