Answer 1

*I used here cursor and temp table to to get the output y for yellow,R for Red and G for Green. 

create table #test(
[Date] date,  
Item varchar(20), 
OrderQty int,  
AvailQty int 
) 

insert into #test values 

('2016-08-11', 'A', 10, 50), 

('2016-08-12','A', 20, 50), 

('2016-08-13','A', 30, 50), 

('2016-08-12','B', 40, 30), 

('2016-08-13','B', 50, 30), 

('2016-08-13','C', 100, 300), 

('2016-08-14','C', 170, 300), 

('2016-08-15','C', 40, 300), 

('2016-08-16','C', 30, 300) 


Alter table #TEST 
Add id int identity(1,1) 

--drop table #itemValue 
create table #itemValue (item varchar(100),AvailValue int) 

insert into #itemValue select distinct item,AvailQty from #TEST 

declare @item varchar(50) 

declare @order int 

declare @id int 

declare curname cursor 

Local scroll static 

for 

select Id,Item,OrderQty from #test 

open curname 

Fetch next from curname 

into @id,@item,@order 

declare @tem2 as int 

print cast(@id as varchar(1000)) 

set @tem2=(select AvailValue from #itemValue where item=@item) 

-------------------------------------------------------------------- 
if(@tem2>@order) 

begin 

update #test set st='G' where Item=@item and id=@id 

update #itemValue set AvailValue=AvailValue-@order where item=@item 

end 

else if(@tem2<@order) 

begin 

update #test set st='Y' where Item=@item and id=@id 

update #itemValue set AvailValue=0 where item=@item 

end 

else 

begin 

update #test set st='R' where Item=@item and id=@id 

end 
-------------------------------------------------------------------- 

while @@FETCH_STATUS=0 

begin 

declare @tem1 as int 

print cast(@id as varchar(1000)) 

print cast(@tem1 as varchar(100)) 

--update #itemValue set AvailValue=AvailValue-@order where item=@item 

set @tem1=(select AvailValue from #itemValue where item=@item) 

if(@tem1>@order) 

begin 

update #test set st='G' where Item=@item and id=@id 

update #itemValue set AvailValue=AvailValue-@order where item=@item 

end 

else if(@tem1=0) 

begin 

update #test set st='R' where Item=@item and id=@id 

end 

else if(@tem1<@order) 

begin 

update #test set st='Y' where Item=@item and id=@id 

update #itemValue set AvailValue=0 where item=@item 

end 

Fetch next from curname 

into @id,@item,@order 
--print cast(@item as varchar(1000)) 
end*
