目前姐姐们对相关于sql server触发器写法眼前一幕让人没有意外，姐姐们都想要分析一下sql server触发器写法，那么美玲也在网络上收集了一些对相关于sql数据库触发器怎么写的一些信息来分享给姐姐们，详情曝光令人惊个呆，姐姐们一起来看看吧。

create trigger trg_表a on [dbo].[表a] for insert as insert into 表b select inserted.日期,inserted.数据b-表a.数据b as 数据b,inserted.数据c-表a.数据c as 数据c from inserted,.

create trigger tri_table1_id on table1 for delete as begin declare @id int select @id=id from deleted update table1 set id=id-1 where id>@id end

基本语法格式 create trigger tri_name on table for insert/update/deleted as sql code 例: create trigger tri_mc(tri_mc:自定义触发器的名称) on table (table:触发的表名) for .

你这个写法是oracle的.sqlserver没有for each row也没有referencing.create trigger 月工资变动 on 考勤 after update begin declare @一月份缺勤扣薪_old .

基本语法格式 create trigger tri_name on table for insert/update/deleted as sql code 例:create trigger tri_mc(tri_mc:自定义触发器的名称) on table (table:触发的表名) for .

假如有表course字段有courseid,coursename,studentid 假如有表studentinfo 字段有studenid,studentname,score 现要删除某一学生,用触发去自动删除course中该学生信息 create trigger deletecourse on studentinfo after delete begin delete from course where studentid in (select studentid from deleted) //deleted 为删除的那条数据 end go

create trigger tr_studentb_inup for insert,update as begin update a set ssex = case when b.ssex ='男' then 'A' when b.ssex ='女' then 'H' else 'O' end from studentb a,inserted b where a.sno =b.sno end

通常创建触发器以在不同表中的逻辑相关数据之间实施引用完整性或一致性.例子: -- 创建一个表(数据库设计的部分) Create Table OrderLog ( EditDate smalldatetime ) -- 创建触发器,当OrderList表被UPDATE的时候,执行一段操作 CREATE TRIGGER tr_OrderList_Log On OrderList AFTER UPDATE AS Insert Into OrderLog(EditDate) Values(getDate()) GO -- 修改表OrderList中的OutDate,使得触发器被执行 Update OrderList Set OutDate = getDate.

create triggert gr_name on Class for update as update Student set class='new'

create trigger InsertCnt_info_cnt_msg on cnt_info for insert as begin declare @countip varchar(50) declare @username varchar(500) declare @userid int select @countip=counterip,@username=username from inserted if exists(select counterip from cnt_info where counterip=@countip) update cnt_msg set count01=count01+1 else update cnt_msg set count01=count01+1 and ip_hits=ip_hits+1 end

这篇文章到这里就已经结束了，希望对姐姐们有所帮助。
