如何,我需要先顯示正數,負數,而在SQL Server排序號2008的正負號排序,以顯示第一
防爆正數: 可以說我有號碼 - 4,-3,null,2,3 Then then result:2,3,-4,-3,null

根據你的小例子,你似乎想要正數的順序是遞增的,然後是負數依次遞增。
這使問題稍微有趣一些。試試這個order by
條款:
order by (case when col > 0 then 2 when col < 0 then 1 else 0 end) desc,
col asc
下面是一個例子:
with t as (select 2 as col union all select 3 union all select -4 union all select -3 union all select null)
select *
from t
order by (case when col > 0 then 2 when col < 0 then 1 else 0 end) desc,
col asc;
