Question

在SQL Server 2008 R2中，您可以在调试死锁时使用以下命令查找所有打开的事务：

DBCC OPENTRAN

但是，该功能在Windows Azure SQL数据库中不可用;它改为抛出错误：

"DBCC command 'OPENTRAN' is not supported in this version of SQL Server."

sp_who2存储过程也不存在。

在Azure版本的SQL Server中获取所有打开的事务的正确查询是什么？

Answer 1

尝试使用DMV：

SELECT *
FROM sys.dm_tran_active_transactions

SELECT *
FROM sys.dm_tran_database_transactions

SELECT *
FROM sys.dm_tran_session_transactions

Answer 2

试试这个脚本：解释所有需要的案例。

SELECT 
     tdt.transaction_id
     ,tst.session_id
     ,tdt.database_transaction_begin_time
     ,CASE tdt.database_transaction_type
        WHEN 1 THEN 'Read/write transaction'
    WHEN 2 THEN 'Read only transaction'
    WHEN 3 THEN 'System transaction'
      END transaction_type
     ,CASE tdt.database_transaction_state
    WHEN 1 THEN 'Transaction not initialized'
    WHEN 3 THEN 'Transaction has not generated by any log'
    WHEN 4 THEN 'Transaction has generated by log'
    WHEN 5 THEN 'Transaction Prepared'
    WHEN 10 THEN 'Transaction Committed'
    WHEN 11 THEN 'Transaction Rolled back'
    WHEN 12 THEN 'Transaction committed and log generated'
     END transaction_state     
FROM sys.dm_tran_database_transactions tdt
INNER JOIN sys.dm_tran_session_transactions tst
  ON tst.transaction_id = tdt.transaction_id
