Question

alright i built this stored procedure to take the columns from a stagging table and copy them into my other table, but if these four columns are duplicates it wont insert the rows, works fine.

however, what i want to do is if only the tour, taskname and deptdate are the same, then i will update the rest of the information. and if all four columns are the same dont instert.

INSERT INTO dashboardtasks1
    SELECT [tour], [taskname], [deptdate], [tasktype], [desc], [duedate], [compdate], [comments], [agent], [compby], [graceperiod]
    FROM staggingtasks
    WHERE NOT EXISTS(SELECT * 
                     FROM dashboardtasks1 
                     WHERE (staggingtasks.tour=dashboardtasks1.tour and
                         staggingtasks.taskname=dashboardtasks1.taskname and 
    staggingtasks.deptdate=dashboardtasks1.deptdate and 
   staggingtasks.duedate=dashboardtasks1.duedate 
    )
                     )

i saw something like this

INSERT INTO table (a,b,c) VALUES (1,2,3)
  ON DUPLICATE KEY UPDATE c=c+1;

UPDATE table SET c=c+1 WHERE a=1;

but how could i do it if my stated 3 columns are the samed then update?

or is there a way to do this with an if statement and use 2 different queries, but how would my if statement work would it check if the row exists in the table i am uploading to and then run the insert statement?

or what if i did something like

alter PROCEDURE test

AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here


update dashboardtasks set
    duedate = s.duedate
from staggingtasks as s
    where s.tour=dashboardtasks.tour and
            s.taskname=dashboardtasks.taskname and 
        s.deptdate=dashboardtasks.deptdate


INSERT INTO dashboardtasks
SELECT [tour], [taskname], [deptdate], [tasktype], [desc], [duedate], [compdate], [comments], [agent], [compby], [graceperiod]
FROM staggingtasks
WHERE NOT EXISTS(SELECT * 
                 FROM dashboardtasks 
                 WHERE (staggingtasks.tour=dashboardtasks.tour and
                       staggingtasks.taskname=dashboardtasks.taskname and 
staggingtasks.deptdate=dashboardtasks.deptdate and 
staggingtasks.duedate=dashboardtasks.duedate 
)
                 )

This might work for you.

update dashboardtasks1 set
  tasktype = s.tasktype,
  [desc] = s.[desc],
  duedate = s.duedate,
  compdate = s.compdate,
  comments = s.comments,
  agent = s.agent,
  compby = s.compby,
  graceperiod    = s.graceperiod
from staggingtasks as s
where
  s.tour=dashboardtasks1.tour and
  s.taskname=dashboardtasks1.taskname and 
  s.deptdate=dashboardtasks1.deptdate and
  not exists (select *
              from dashboardtasks1 as d
              where s.tour=d.tour and
                    s.taskname=d.taskname and 
                    s.deptdate=d.deptdate and
                    s.duedate=d.duedate
             )        


insert into dashboardtasks1 (tour, taskname, deptdate, tasktype, [desc], duedate, compdate, comments, agent, compby, graceperiod)
select tour, taskname, deptdate, tasktype, [desc], duedate, compdate, comments, agent, compby, graceperiod
from staggingtasks as s
where not exists (select *
                  from dashboardtasks1 as d
                  where s.tour=d.tour and
                        s.taskname=d.taskname and

                 )
