Question

我想在插入后在学生表上创建一个触发器，以在学生审核表中添加行（服务器用户名，日期，注释），其中注释为“[用户名]在表中插入带有键的新行= [键值]学生

create trigger t1 on Student
after insert
as
declare @x int
begin
insert into Audit
(ServerUserName, Date, Note)
select SUSER_SNAME(), getdate(),SUSER_SNAME()+'Insert New Row with Key'+@x+'in Student '
from Student t
end
go

我怎么能用@x做这个，我的意思是@x是等于键

首先，删除declare @x int行。您无法将参数传递给触发器。如果您想要插入行，可以像inserted一样选择它;

create trigger t1 on Student
after insert
as
begin
    insert into Audit
    (ServerUserName, Date, Note)
    select SUSER_SNAME(), getdate(),SUSER_SNAME()+'Insert New Row with Key'+cast(t.Id as nvarchar(10))+'in Student '
    from Student t where Id IN (select Id from inserted)
end
go

如何在插入后在表上创建触发器以在Audit表中添加Row
