Question

每当在CUSTOMER表中发生INSERT时，我需要调用＆＃34; StoredProcedure1 ＆＃34;和更新发生在CUSTOMER表中，我需要调用＆＃34; StoredProcedure2 ＆＃34;在触发器中。 如何确定是否在SQL Server 2008中插入或更新触发器。

有人可以帮我解决一下吗？

代码：

CREATE TRIGGER Notifications ON CUSTOMER
FOR INSERT,UPDATE
AS
BEGIN
DECLARE @recordId varchar(20);
set @recordId= new.Id;
    //if trigger is insert at the time I call to SP1
        EXEC StoredProcedure1 @recordId
    //if trigger is Upadeted at the time I call to SP2
        EXEC StoredProcedure2 @recordId
END

Answer 1

让SQL Server成为SQL Server，让它为您完成工作！

为每个更改事件（插入，更新和/或删除）创建单独的触发器。将每个逻辑放入需要它的触发器中。无需检查事件类型。

除非快速，快速且无法阻止他人，否则不要调用程序。

Answer 2

解决此问题的最简单方法是使用两个触发器，一个用于插入，另一个用于更新。

CREATE TRIGGER InsertNotifications ON CUSTOMER
FOR INSERT
AS
BEGIN
DECLARE @recordId varchar(20);
set @recordId= new.Id;
    //if trigger is insert at the time I call to SP1
        EXEC StoredProcedure1 @recordId

END

CREATE TRIGGER UpdateNotifications ON CUSTOMER
FOR UPDATE
AS
BEGIN
DECLARE @recordId varchar(20);
set @recordId= new.Id;
    //if trigger is Upadeted at the time I call to SP2
        EXEC StoredProcedure2 @recordId
END

Answer 3

尝试使用此代码来触发INSERT，UPDATE和DELETE。这适用于Microsoft SQL SERVER 2008

if (Select Count(*) From inserted) > 0 and (Select Count(*) From deleted) = 0
begin
   print ('Insert...')
end

if (Select Count(*) From inserted) = 0 and (Select Count(*) From deleted) > 0
begin
   print ('Delete...')
end

if (Select Count(*) From inserted) > 0 and (Select Count(*) From deleted) > 0
begin
   print ('Update...')
end

Answer 4

在INSERT上，虚拟DELETED表将为空。

Answer 5

create or replace trigger comp
before
insert or delete or update
on student
referencing old as o new as n
for each row
begin
  if deleting then
           insert into student_backup values
      (:o.studid,:o.studentname,:o.address,:o.contact_no,:o.branch,sysdate);
  end if;
  if inserting then
        insert into student_backup values
      (:n.studid,:n.studentname,:n.address,:n.contact_no,:n.branch,sysdate);
 end if;
  if updating then
       insert into student_backup values
      (:o.studid,:o.studentname,:o.address,:o.contact_no,:o.branch,sysdate);
  end if;
end comp;
