sql - 完成的 COMMIT 语句是否意味着它已完成提交？

Question

一旦提交语句完成，这是否意味着它实际上已完成提交？或者这是否意味着提交操作已经完成，但它仍然可能在后台提交？

Answer 1

是的。

曾经COMMIT命令成功完成，操作完成，并永久记录更改。没有需要以某种方式完成操作的后台进程的概念。

这是对 the MySQL documentation 的引用:

COMMIT commits the current transaction, making its changes permanent.

再举一个例子，Oracle docs说:

Use the COMMIT statement to end your current transaction and make permanent all changes performed in the transaction. A transaction is a sequence of SQL statements that Oracle Database treats as a single unit. This statement also erases all savepoints in the transaction and releases transaction locks.
