SQL Server：触发器触发

Question

CREATE table1;
CREATE table2;

CREATE trigger1 ON table1 AFTER DELETE AS DELETE FROM table1;
CREATE trigger2 ON table1 AFTER DELETE AS DELETE FROM table2;

DELETE FROM table1

上次查询将触发trigger1和trigger2。

trigger1是否再次触发trigger2（如果设置了数据库默认选项）？

Answer 1

这取决于服务器上的nested triggers设置。参见：

Answer 2

如果选项RECURSIVE_TRIGGERS设置为on并且配置“嵌套触发器”设置为1然后是触发trigger1将导致trigger1和trigger2再次触发，然后再触发等等至32级深度后触发。否则他们不会递归发射。
