CREATE OR REPLACE TRIGGER trigger_name<before | after | instead of> <insert | update | delete> ON table_name
[FOR EACH ROW]
WHEN (condition)
DECLARE
BEGIN
--触发器代码
END;
Trigger_name是触发器的名称。<before | after | instead of>可以选择before或者after或instead of。
Before表示在DML语句实施前执行触发器，而after表示在在dml语句实施之后执行触发器，instead of触发器用在对视图的更新上。
<insert | update | delete>可以选择一个或多个DML语句，如果选择多个，则用or分开，如：insert or update。
Table_name是触发器关联的表名。
[FOR EACH ROW]为可选项，如果注明了FOR EACH ROW，则说明了该触发器是一个行级的触发器，DML语句处理每条记录都会执行触发器；
否则是一个语句级的触发器，每个DML语句触发一次。
WHEN后跟的condition是触发器的响应条件，只对行级触发器有效，当操作的记录满足condition时，触发器才被执行，否则不执行。
Condition中可以通过new对象和old对象（注意区别于前面的:new和:old，在代码中引用需要加上冒号）来引用操作的记录。
