Recentemente mi è tornato utile avere l’elenco delle transazioni attive con il relativo statemente T-SQL.
Ecco la query che ho utilizzato:
SELECT s_tst.[session_id],
s_es.[login_name] AS [Login Name],
DB_NAME (s_tdt.database_id) AS [Database],
s_tdt.[database_transaction_begin_time] AS [Begin Time],
s_tdt.[database_transaction_log_record_count] AS [Log Records],
s_tdt.[database_transaction_log_bytes_used] AS [Log Bytes],
s_tdt.[database_transaction_log_bytes_reserved] AS [Log Rsvd],
s_est.[text] AS [Last T-SQL Text],
s_eqp.[query_plan] AS [Last Plan]
FROM sys.dm_tran_database_transactions s_tdt
JOIN sys.dm_tran_session_transactions s_tst
ON s_tst.[transaction_id] = s_tdt.[transaction_id]
JOIN sys.[dm_exec_sessions] s_es
ON s_es.[session_id] = s_tst.[session_id]
JOIN sys.dm_exec_connections s_ec
ON s_ec.[session_id] = s_tst.[session_id]
LEFT OUTER JOIN sys.dm_exec_requests s_er
ON s_er.[session_id] = s_tst.[session_id]
CROSS APPLY sys.dm_exec_sql_text (s_ec.[most_recent_sql_handle]) AS s_est
OUTER APPLY sys.dm_exec_query_plan (s_er.[plan_handle]) AS s_eqp
ORDER BY [Begin Time] ASC;
Utile nel caso di transazioni bloccate\bloccanti!
