SQL Triggers: Are they fired after a statement or a transaction?

Question

我正在寻找一个答案，以确定在语句引起的操作之后是立即触发SQL中的触发器，还是仅在提交整个事务之后？

Answer 1

In SQL Server, AFTER triggers are fired immediately following an action caused by a statement. (A transaction can be rolled back by a trigger).

There are also INSTEAD OF triggers which fire in place of the triggering action.
