SQL Server 结果集循环处理的 避免游标处理方法

结果集循环，避免使用游标的方法（游标的性能一般不好）：
创建一个临时表：

declare @tempTable table(ID int identity(1,1), unitID int, unitState int, partID bigint)
insert into @tempTable
select distinct u.id, u.UnitStateID, u.PartID
from ffUnit u
join ffUnitDetail ud on u.id =  ud.unitID
where ud.InmostPackageID = @packageID

declare @i int
declare @j int
set @i = 0

select @j = MAX(ID) from @tempTable
begin tran---Rex
while @i < @j begin
set @i = @i+1
set @UnitID = null
set @CurrUnitStateID = null
set @PartID = null

select @UnitID=unitID, @CurrUnitStateID = unitState, @PartID = partID from @tempTable where ID = @i
exec @ret = objUNTCheckRouting @UnitID, @xmlPart, @xmlStation
if @ret <> 0 or @@ERROR >0
begin
if @@TRANCOUNT = 1 rollback else commit
return @ret
end

end

commit tran
