如果不向数据库(例如 SQL Server)提交事务会发生什么?

What happens if you don#39;t commit a transaction to a database (say, SQL Server)?(如果不向数据库(例如 SQL Server)提交事务会发生什么?)

问题描述

假设我有一个查询:

begin tran
-- some other sql code

然后我忘记提交或回滚.

And then I forget to commit or roll back.

如果另一个客户端尝试执行查询，会发生什么?

If another client tries to execute a query, what would happen?

推荐答案

只要你不COMMIT 或 ROLLBACK 一个事务，它仍然在运行"并且可能持有锁.

As long as you don't COMMIT or ROLLBACK a transaction, it's still "running" and potentially holding locks.

如果您的客户端(应用程序或用户)在提交之前关闭了与数据库的连接，则任何仍在运行的事务都将回滚并终止.

If your client (application or user) closes the connection to the database before committing, any still running transactions will be rolled back and terminated.
