在 SQL Server 中，我如何知道我当前使用的是哪种事务模式?

问题描述

在 SQL Server 中，我如何知道我当前使用的是哪种事务模式?例如自动提交、显式或隐式.以及如何使用 tsql 将一种模式更改为另一种模式?非常感谢.

In SQL Server, how do I know what transaction mode I'm currently using? Such as autocommit, explicit, or implicit. And how can I change one mode to another using tsql?Great thanks.

推荐答案

IF @@TRANCOUNT = 0 PRINT 'No current transaction, autocommit mode (default)'
ELSE IF @@OPTIONS & 2 = 0 PRINT 'Implicit transactions is off, explicit transaction is currently running'
ELSE PRINT 'Implicit transactions is on, implicit or explicit transaction is currently running'

我认为没有办法确定当前事务是显式启动还是隐式启动.因此，这段代码只是尝试猜测:如果 IMPLICIT_TRANSACTIONS 为 OFF，则假定事务已显式启动.

I don't think there is a way to determine whether current transaction was started explicitly or implicitly. So, this code just tries to guess: if IMPLICIT_TRANSACTIONS is OFF, the transaction is assumed to be started explicitly.

MSDN 参考资料:

• @@OPTIONS 函数
• 选项的数值
• @@TRANCOUNT
