11
..
sql:select * from mytable order by a

我想要从大到小的排列如何办？如：
1
2

..
---------------------------------------------------------------
select * from yourtable order by cast(a as int)
---------------------------------------------------------------
对，你的字段是字符型的，要变成int的才行
---------------------------------------------------------------
order by cast(substring(a,1,charindex('-',a)-1) as int),a
