sys.dm_tran_active_transactionssys.dm_tran_active_transactions DMV 包含有关打开事务的数据,这些事务可以加入其他 DMV,以获取等待提交或回滚事务的完整信息。 使用以下查询返回有关已加入其他 DMV(包括sys.dm_tran_session_transactions)的打开事务的信息。 考虑事务的当前状态、transaction_begin_time和其他情况数据,以评估其是否可能是阻塞源。SELECT tst.session_id, [database_name] = db_name(s.database_id) , tat.transaction_begin_time , transaction_duration_s = datediff(s, tat.transaction_begin_time, sysdatetime()) , transaction_type = CASE tat.transaction_type WHEN 1 THEN 'Read/write transaction' WHEN 2 THEN 'Read-only transaction' WHEN 3 THEN 'System transaction' WHEN 4 THEN 'Distributed transaction' END , input_buffer = ib.event_info, tat.transaction_uow , transaction_state = CASE tat.transaction_state WHEN 0 THEN 'The transaction has not been completely initialized yet.'
