1. 触发器方法
create Trigger Trigger_Name on Table1 after delete,UPDATE as begin set nocount on; if exists(select * from inserted) update Table2 set field1 = (select field1 from inserted) where field1 = (select field1 from inserted) else delete from Table2 where field1 = (select field1 from deleted) set nocount off; end
2. 创建外键关联关系
ALTER TABLE table1 ADD CONSTRAINT [FK_Table1_Table2] FOREIGN KEY(field1) REFERENCES table2 (field1) ON UPDATE CASCADE ON DELETE CASCADE
