--我们有一个table如下，需要跟踪修改对该表的insert/update/delete操作：

create table testMonitor(c1 int, c2 char(10))


--创建的辅助表如下：

create table tempLog_testMonitor(
rowID bigint identity(1,1),
hostname nchar(128),
program_name nchar(128),
nt_domain nchar(128),
nt_username nchar(128),
net_address nchar(12),
loginame nchar(128),
login_time datetime,
EventType nvarchar(30),
parameters int,
EventInfo nvarchar(255)
)

--创建的trigger如下：

create trigger trg_testMonitor
on testMonitor
for insert,update,delete
as
begin

            declare @hostname nchar(128)
            declare @program_name nchar(128) 
            declare @nt_domain nchar(128) 
            declare @nt_username nchar(128) 
            declare @net_address nchar(12)
            declare @loginame nchar(128)
            declare @login_time datetime
            declare @rowID bigint

            
            insert into tempLog_testMonitor(EventType,parameters,EventInfo)
            exec ('dbcc inputbuffer(@@spid)')
            select @rowID = scope_identity()                  
            select  @hostname = hostname,
                        @program_name = program_name,
                        @nt_domain = nt_domain,
                        @nt_username = nt_username,
                        @net_address = net_address,
                        @loginame = loginame,
                        @login_time = login_time
            from master..sysprocesses where spid = @@spid

            update tempLog_testMonitor set 
            hostname = @hostname,
            program_name = @program_name,
            nt_domain = @nt_domain,
            nt_username = @nt_username,
            net_address = @net_address,
            loginame = @loginame,
            login_time = @login_time
            where rowID = @rowID
end

--如果我们执行如下的语句：

insert into testmonitor values(1,'aaa')
update testmonitor set c2 = 'bbb'
delete from testmonitor

--您再查询辅助表，就能看到对表修改的相关信息：

select * from tempLog_testMonitor
