loop through values and update after each one completes - sql-server

Question

I have the following code that i need to run for 350 locations it takes an hour to do 5 locations so I run 5 at a time by using where location_code in ('0001', '0002', '0003', '0005', '0006') I would like to create a temp table with 2 columns one location_id and the other completed and loop through each value on the location_id column then update the completed column with date and time stamp when complete and commit after each. This way I can just let it run and if i need to kill it i can see the last completed location_id and know where to restart the process from or better yet have it check for a vaule in the completed column and if exists go to the next .....
--Collecting all records containing remnant cost. You will need to specify the location number(s). In the example below we're using location 0035
select sku_id, ib.location_id, price_status_id, inventory_status_id, sum(transaction_units) as units, sum(transaction_cost) as cost,
sum(transaction_valuation_retail) as val_retail, sum(transaction_selling_retail) as sell_retail
into #remnant_cost
from ib_inventory ib
inner join location l on l.location_id = ib.location_id
where location_code in ('0001', '0002', '0003', '0005', '0006')
group by sku_id, ib.location_id, price_status_id, inventory_status_id
having sum(transaction_units) = 0
and sum(transaction_cost) <> 0
--Verify the total remnant cost.
select location_id, sum(units) as units, sum(cost) as cost, sum(val_retail) as val_retail, sum(sell_retail) as sell_retail

group by location_id
select *

Making some assumptions about your schema:
-- A working table to track progress that will stick around.
create table dbo.Location_Codes
( Location_Code VarChar(4), Started DateTime NULL, Completed DateTime NULL );
Then break up the work this way:
if not exists ( select 42 from dbo.Location_Codes where Completed is NULL )
begin
-- All of the locations have been processed (or this is the first time through).
delete from dbo.Location_Codes;
-- Get all of the location codes.
insert into dbo.Location_Codes
select Location_Code, NULL, NULL
from Location;
end
-- Temporary table to make things easier.
declare #Pass_Location_Codes as Table ( Location_Code VarChar(4) );
-- Loop until all locations have been processed.
while exists ( select 42 from dbo.Location_Codes where Completed is NULL )
begin
-- Get the next five locations for which processing has not completed.
delete from #Pass_Location_Codes;
insert into #Pass_Location_Codes
select top 5 Location_Code
from dbo.Location_Codes
where Completed is NULL
order by Location_Code;
-- Record the start date/time.
update dbo.Location_Codes
set Started = GetDate()
where Location_Code in ( select Location_Code from #Pass_Location_Codes );
-- Run the big query.
select ...
where Location_Code in ( select Location_Code from #Pass_Location_Codes )
...
-- Record the completion date/time.
update dbo.Location_Codes
set Completed = GetDate()
where Location_Code in ( select Location_Code from #Pass_Location_Codes );
end
