你刚才有点错误的方式

IF NOT EXISTS(SELECT *
                  FROM   dashboardtasks
                  WHERE  ( @tour = dashboardtasks.tour
                           and @taskname = dashboardtasks.taskname
                           and @deptdate = dashboardtasks.deptdate
                           and @duedate = dashboardtasks.duedate
                           and  @tourname = dashboardtasks.tourname
                         and @agent = dashboardtasks.agent
                         )
)  
BEGIN
  INSERT INTO dashboardtasks
           ([tour]
           ,[tourname]
           ,[taskname]
           ,[deptdate]
           ,[tasktype]
           ,[desc]
           ,[duedate]
           ,[agent]
           ,[graceperiod])

     VALUES (@tour,
           @tourname,
           @taskname ,
           @deptdate,
           @tasktype  ,
           @desc ,
           @duedate ,
           @agent ,
           @graceperiod
                  )

END
