Question

我很惊讶这还没有得到解决但是我在stackoverflow中搜寻并且无法找到它。

基本上，我尝试在系统中启用学生帐户的大量删除，但希望将这些记录存档，以便记录仍然可用，而不再是系统的一部分。

我已经写了一个删除触发器来自动将已删除的记录存档到存档表中。

但是，我不知道如何使触发器接受处理多个记录，至少对于insert into语句。现在，我的insert into语句只会将内存中已删除表的第一条记录输入到我的归档表中。我使用的是SQL Server。

drop trigger trgDelete;

create TRIGGER trgDelete ON KPMG_URecruiting_CIS484_Group21.dbo.Student AFTER DELETE
as begin
	Declare @Email varchar (50);
	Declare @Password varchar(50);
	Declare @FirstName varchar(50);
	Declare @MiddleName varchar(50);
	Declare @LastName varchar(50);
	Declare @PreferredName varchar(50);	
	Declare @CellPhone char(20);
	Declare @Notes varchar(max);
	Declare @Institution varchar(100);
	Declare @EducationLevel char(20);
	Declare @Major varchar(100);
	Declare @Minor varchar(100);
	Declare @GPA float;
	Declare @GradDate date;
	Declare @CPA bit;
	Declare @Service varchar(100);
	Declare @Industry varchar(100);
	Declare @Location varchar(100);

	Select @Email=d.Email from deleted d;
	Select @Password=d.Password from deleted d;
	Select @FirstName=d.FirstName from deleted d;
	Select @MiddleName=d.MiddleName from deleted d;
	Select @LastName=d.LastName from deleted d;

	Select @GradDate=d.GradDate from deleted d;
	Select @Service=d.Service from deleted d;
	Select @Industry=d.Industry from deleted d;
	Select @Location=d.Location from deleted d;

	Insert into Student_Archive 
	(
		Email, Password, FirstName, MiddleName, LastName, PreferredName, CellPhone, Notes, Institution, EducationLevel, Major, Minor, GPA, GradDate, CPA, Service, Industry, Location, Audit_TimeStamp
	)
	Values 
	(
		@Email, @Password, @FirstName, @MiddleName, @LastName, @PreferredName, @CellPhone, @Notes, @Institution,@EducationLevel, @Major, @Minor, @GPA, @GradDate, @CPA, @Service, @Industry, @Location, getdate());

你能指点我如何强制触发器在内存中删除的表中执行插入到EACH记录而不仅仅是第一个吗？任何建议都非常感激。

Answer 1

好吧，直接执行INSERT：

create TRIGGER trgDelete ON KPMG_URecruiting_CIS484_Group21.dbo.Student AFTER DELETE
as 
begin

    Insert into Student_Archive 
    (
        Email, Password, FirstName, MiddleName, LastName, PreferredName, CellPhone, Notes, Institution, EducationLevel, Major, Minor, GPA, GradDate, CPA, Service, Industry, Location, Audit_TimeStamp
    )
    SELECT Email, Password, FirstName, MiddleName, LastName, PreferredName, CellPhone, Notes, Institution, EducationLevel, Major, Minor, GPA, GradDate, CPA, Service, Industry, Location, Audit_TimeStamp, getdate()
    FROM DELETED;

end

Answer 2

试试这个 - 只是一个简单的，简单的基于集合的方法：

CREATE TRIGGER trgDelete 
ON KPMG_URecruiting_CIS484_Group21.dbo.Student 
AFTER DELETE
AS BEGIN
    INSERT INTO dbo.Student_Archive (Email, Password, FirstName, MiddleName, LastName, PreferredName, CellPhone, Notes, Institution, EducationLevel, Major, Minor, GPA, GradDate, CPA, Service, Industry, Location, Audit_TimeStamp)
       SELECT
          Email, Password, FirstName, MiddleName, LastName, PreferredName, CellPhone, Notes, Institution, EducationLevel, Major, Minor, GPA, GradDate, CPA, Service, Industry, Location, SYSDATETIME()
      FROM
         Deleted
END
