Alternative to cursor in SQL Server

You can use temp table in the same manner as you use SQL Server cursor

create table #temp (
    value1 int,
    value2 int
)

Declare 
    @SomeValue1 int,
    @SomeValue2 int

insert into #temp (
    value1, 
    value2)
select 
    field1, 
    field2
from realTable
--where some condition

select top 1 
    @SomeValue1 = value1, 
    @SomeValue2 = value2
from #temp

-- while we have rows in the table, do work with them.
while @SomeValue1 is not null 
Begin

    -- Do something with value1 and value2


    -- delete the row we have just worked with
    delete from #temp where value1=@SomeValue1 and value2=@SomeValue2

    -- don't forget this bit!! otherwise you'd be stuck in the infinite loop, 
    -- as variable is not reset to null on empty table
    set @SomeValue1 = null  

    -- get the next row  in the table
    select top 1 @SomeValue1=value1, @SomeValue2 = value2
    from #temp

End

-- here we are done, can drop the temp table
drop table #temp

Probably you would benefit from adding @ID uniqueidentifier to temp table, in case you have repeating data, and delete rows from temp table based by the ID value
