Question

我有一个简单的触发器，当用户在表中插入行时运行。

由于批量插入和插入顺序也很重要，有没有办法在触发器中保留它？

可以这样做，还是有更好的方法呢？

ALTER TRIGGER simpleTrigger
ON shop
AFTER INSERT AS

SELECT * INTO #orderedInserted from inserted i ORDER BY i.Emp_Sal

declare @empid int;
    declare @empname varchar(100);
    declare @empsal decimal(10,2);
    declare @audit_action varchar(100);

    select @empid=#orderedInserted.Emp_ID from inserted i;  
    select @empname=#orderedInserted.Emp_Name from inserted i;  
    select @empsal=#orderedInserted.Emp_Sal from inserted i;    
    set @audit_action='Inserted Record -- After Insert Trigger.';

    insert into Employee_Test_Audit
           (Emp_ID,Emp_Name,Emp_Sal,Audit_Action,Audit_Timestamp) 
    values(@empid,@empname,@empsal,@audit_action,getdate());
GO;

Answer 1

类似这样的事情

ALTER TRIGGER simpleTrigger
ON shop
AFTER INSERT AS

    insert into Employee_Test_Audit
           (Emp_ID,Emp_Name,Emp_Sal,Audit_Action,Audit_Timestamp) 
    select i.Emp_ID, i.Emp_Name, i.Emp_Sal, 'Inserted Record -- After Insert Trigger.', getdate()
    from inserted i
    order by i.Emp_Sal

GO;

但如果Employee_Test_Audit中没有标识列，则ORDER BY无关紧要

很简单，你不使用变量：

ALTER TRIGGER simpleTrigger
ON shop
AFTER INSERT AS    
    declare @audit_action varchar(100);
    set @audit_action='Inserted Record -- After Insert Trigger.';

    insert into Employee_Test_Audit
           (Emp_ID,Emp_Name,Emp_Sal,Audit_Action,Audit_Timestamp) 
    SELECT i.Emp_ID, i.Emp_Name, i.Emp_sal, @audit_action, getdate() from inserted i ORDER BY i.Emp_Sal ;
GO;
