撰写从亚洲开发银行到变数/更新触发器的记录
原标题:Write a record from DB to varchar variable/update trigger

i 有两个问题,要求帮助:

i 必须在玩具表中制造触发器,以记录任何变化,例如更新、删除和插入。

i 希望在表格中节省一个栏目,储存记录中的数据(旧或新字,加/提要),或储存记录旧版本和新版本之间的差异(更新日期)。

My problem is how to store this information, especially how to "convert" simple record into string, and how to log updates. i thought i can use something like:

exec ( select   + @col +   from deleted )

但是,它并不发挥作用。

页: 1 i 不知道一栏的名称及其编号(我希望我的触发点应为每个表格的通用)。 a. 根据指挥储存一栏使用 cur子:

select 
  COLUMN_NAME 
from 
  INFORMATION_SCHEMA.COLUMNS 
where 
  TABLE_NAME = (SELECT object_name(parent_obj) 
                FROM sysobjects WHERE id = @@procid)

请帮助:
