桌子 :
CREATE TABLE GUESTS (
GUEST_ID int IDENTITY(1,1) PRIMARY KEY,
GUEST_NAME VARCHAR(50),
GUEST_SURNAME VARCHAR(50),
ADRESS VARCHAR(100),
CITY VARCHAR(50),
CITY_CODE VARCHAR(10),
COUNTRY VARCHAR(50),
STATUS VARCHAR(20),
COMMENT nvarchar(max);
对于日志记录:
CREATE TABLE AUDIT_GUESTS (
ID int IDENTITY(1,1) PRIMARY KEY,
GUEST_ID int,
OLD_GUEST_NAME VARCHAR(50),
NEW_GUEST_NAME VARCHAR(50),
OLD_GUEST_SURNAME VARCHAR(50),
NEW_GUEST_SURNAME VARCHAR(50),
OLD_ADRESS VARCHAR(100),
NEW_ADRESS VARCHAR(100),
OLD_CITY VARCHAR(50),
NEW_CITY VARCHAR(50),
OLD_CITY_CODE VARCHAR(10),
NEW_CITY_CODE VARCHAR(10),
OLD_COUNTRY VARCHAR(50),
NEW_COUNTRY VARCHAR(50),
OLD_STATUS VARCHAR(20),
NEW_STATUS VARCHAR(20),
OLD_COMMENT nvarchar(max),
NEW_COMMENT nvarchar(max),
AUDIT_ACTION varchar(100),
AUDIT_TIMESTAMP datetime);
我想在我的GUESTS表上创建一个触发器来记录我表中的所有更改AUDIT_GUESTS.我如何在SQL Server 2014 Express中执行此操作？
我试过了 :
create TRIGGER trgAfterUpdate ON [dbo].[GUESTS]
FOR UPDATE
AS
declare @GUEST_ID int;
declare @GUEST_NAME varchar(50);
declare @GUEST_SURNAME VARCHAR(50);
declare @ADRESS VARCHAR(100);
declare @CITY VARCHAR(50);
declare @CITY_CODE VARCHAR(10);
declare @COUNTRY VARCHAR(50);
declare @STATUS VARCHAR(20);
declare @COMMENT nvarchar(max);
declare @AUDIT_ACTION varchar(100);
declare @AUDIT_TIMESTAMP datetime;
select @GUEST_ID=i.GUEST_ID from inserted i;
select @GUEST_NAME=i.GUEST_NAME from inserted i;
select @GUEST_SURNAME=i.GUEST_SURNAME from inserted i;
select @ADRESS=i.ADRESS from inserted i;
select @CITY=i.CITY from inserted i;
select @CITY_CODE=i.CITY_CODE from inserted i;
select @COUNTRY=i.COUNTRY from inserted i;
select @STATUS=i.STATUS from inserted i;
select @COMMENT=i.COMMENT from inserted i;
if update(GUEST_NAME)
set @audit_action='Updated Record -- After Update Trigger.';
if update(GUEST_SURNAME)
set @audit_action='Updated Record -- After Update Trigger.';
if update(ADRESS)
set @audit_action='Updated Record -- After Update Trigger.';
if update(CITY)
set @audit_action='Updated Record -- After Update Trigger.';
if update(CITY_CODE)
set @audit_action='Updated Record -- After Update Trigger.';
if update(COUNTRY)
set @audit_action='Updated Record -- After Update Trigger.';
if update(STATUS)
set @audit_action='Updated Record -- After Update Trigger.';
if update(COMMENT)
set @audit_action='Updated Record -- After Update Trigger.';
insert into AUDIT_GUESTS
(GUEST_ID,GUEST_NAME,GUEST_SURNAME,ADRESS,CITY,CITY_CODE,COUNTRY,STATUS,COMMENT,audit_action,AUDIT_TIMESTAMP)
values(@GUEST_ID,@GUEST_NAME,@GUEST_SURNAME,@ADRESS,@CITY,@CITY_CODE,@COUNTRY,@STATUS,@COMMENT,@audit_action,getdate());
GO
有点好,但我想看到新旧的价值观.
在SQLite中我有:
CREATE TRIGGER [LOG_UPDATE]
AFTER UPDATE OF [GUEST_NAME], [GUEST_SURNAME], [ADRESS], [CITY], [CITY_CODE], [COUNTRY], [STATUS], [COMMENT]
ON [GUESTS]
BEGIN
INSERT INTO GUESTS_LOG
( GUEST_ID,
NAME_OLD,NAME_NEW,
SURNAME_OLD,SURNAME_NEW,
ADRESS_OLD,ADRESS_NEW,
CITY_OLD,CITY_NEW,
CITY_CODE_OLD,CITY_CODE_NEW,
COUNTRY_OLD,COUNTRY_NEW,
STATUS_OLD,STATUS_NEW,
COMMENT_OLD,COMMENT_NEW,sqlAction,DATE_TIME)
VALUES
(OLD.GUEST_ID,
OLD.GUEST_NAME,NEW.GUEST_NAME,
OLD.GUEST_SURNAME,NEW.GUEST_SURNAME,
OLD.ADRESS,NEW.ADRESS,
OLD.CITY,NEW.CITY,
OLD.CITY_CODE,NEW.CITY_CODE,
OLD.COUNTRY,NEW.COUNTRY,
OLD.STATUS,NEW.STATUS,
OLD.COMMENT,NEW.COMMENT,'record changed',datetime('now','localtime'));
END
它运作正常.只是不知道如何将其传递给SQL服务器.刚开始学习它.

请看Pop Rivett在Simple-talk.com 上的这篇文章.它将指导您创建一个通用触发器,该触发器将记录所有更新列的OLDVALUE,NEWVALUE.代码非常通用,您可以将它应用于您想要审计的任何表,也适用于任何CRUD操作,即INSERT,UPDATE和DELETE.唯一的要求是您要审核的表应该有一个PRIMARY KEY(设计最好的表应该有).
这是与您的GUESTS表相关的代码.
1)创建AUDIT表.
IF NOT EXISTS
(SELECT * FROM sysobjects WHERE id = OBJECT_ID(N'[dbo].[Audit]')
AND OBJECTPROPERTY(id, N'IsUserTable') = 1)
CREATE TABLE Audit
(Type CHAR(1),
TableName VARCHAR(128),
PK VARCHAR(1000),
FieldName VARCHAR(128),
OldValue VARCHAR(1000),
NewValue VARCHAR(1000),
UpdateDate datetime,
UserName VARCHAR(128))
GO
2)在GUESTS表上创建UPDATE触发器,如下所示.
CREATE TRIGGER TR_GUESTS_AUDIT ON GUESTS FOR UPDATE

@field INT ,
@maxfield INT ,
@char INT ,

@PKSelect VARCHAR(1000)
--You will need to change @TableName to match the table to be audited.

SELECT @TableName = 'GUESTS'

RETURN
END
SELECT @field = 0,
@maxfield = MAX(ORDINAL_POSITION)

WHILE @field < @maxfield

SELECT @bit = (@field - 1 )% 8 + 1

这是带有两个错误修复的代码。Royi Namir 在对该问题的已接受答案的评论中提到了第一个错误修复。该错误在 StackOverflow 上的Bug in Trigger Code 中进行了描述。第二个是由@Fandango68 发现的，并修复了名称中有多个单词的列。

我知道这是旧的,但也许这会帮助别人.
不要记录"新"值.您现有的表GUESTS具有新值.您将拥有双重数据输入,而且您的数据库大小将以这种方式增长得太快.
我清理了这个并最小化了这个例子,但是这里是你需要注销变更的表格:
CREATE TABLE GUESTS (
GuestID INT IDENTITY(1,1) PRIMARY KEY,
GuestName VARCHAR(50),
ModifiedBy INT,
ModifiedOn DATETIME
)
CREATE TABLE GUESTS_LOG (
GuestLogID INT IDENTITY(1,1) PRIMARY KEY,
GuestID INT,
GuestName VARCHAR(50),
ModifiedBy INT,
ModifiedOn DATETIME
)
当GUESTS表中的值发生更改时(例如:访客姓名),只需使用触发器将整行数据按原样注销到Log/Audit表.您的GUESTS表具有当前数据,Log/Audit表具有旧数据.
然后使用select语句从两个表中获取数据:
SELECT 0 AS 'GuestLogID', GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS] WHERE GuestID = 1
UNION
SELECT GuestLogID, GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS_LOG] WHERE GuestID = 1
ORDER BY ModifiedOn ASC
您的数据将显示表格的样子,从最旧到最新,第一行是创建的,最后一行是当前数据.您可以确切地看到更改的内容,更改内容以及更改时间.
或者,我曾经有一个循环通过RecordSet的函数(在经典ASP中),并且只显示在网页上更改了哪些值.它创建了一个伟大的审计跟踪,以便用户可以看到随着时间的推移发生了什么变化.
