create or replace trigger bj_customer
before update on customer
for each row
begin
update order set
cu_no=:new.cu_no，
cu_name=:new.cu_name，
cu_address=:new.cu_addess，
where cu_no=:old.cu_no；
end
调用executeUpdate方法即可
Trigger不是java特性也不是java内置的代码，而是其它程序的封装。在Quartz中Trigger是触发器，Quartz中的触发器用来告诉调度程序作业什么时候触发
即Trigger对象是用来触发执行Job的
2.在Java程序里创建触发器String sql=+" CREATE TRIGGER catefiles_trigger AFTER INSERT ON catefiles FOR EACH ROW"
+" begin"
+" declare scannum int"
+" set scannum = (select num from est_client_catescan_status where"
+" cateid=new.cateId and taskid=new.taskId and clientid=new.clientId)"
+" if(scannum>=0) then"
+" update catescan_status set num=scannum+1 where cateid=new.cateId and taskid=new.taskId and clientid=new.clientId"
+" else"
+" insert catescan_status(cateid,num,status,taskid,clientid) values(new.cateId,1,0,new.taskid,new.clientId)"
+" end if"
+" end"
Connection con = DbConnectionManager.getConnection()
PreparedStatement pstmt = con.prepareStatement(sql)
pstmt.execute()
