TRIGGER 触发器的问题
ORA-04098错误解决方法http://www.sudu.cn/info/html/edu/20071225/21007.html-- some piece copy:此时触发器不能编译过去,也不能删除了,因为触发器本身里面定义了ddl操作的触发,产生ora-04098: 触发器 ddl_deny 无效且未通过重新验证。发现是内部严重错误,其他看不出太多错误信息,于是想到采用隐含参数_system_trigger_enabled=false,在数据库启动的时候让所有触发器不起作用,然后删除。数据库8.1.5的提示没这个参数,于是查询了一下:select ksppinm from x$ksppi where substr(ksppinm,1,1)=_and ksppinm like %tri% order by k
