有如下表结构
col1 col2
5 20
6 16
7 10
现在要在col2中查询数据,当查询出来的数据要小于同列中最大值的3/4时 col1取0,并按col1排序
即
col1 col2
6 16
5 20
0 10
------解决方案--------------------
- SQL code
declare @t table (col1 int,col2 int)insert into @tselect 5,20 union allselect 6,16 union allselect 7,10select col1=case when col2<col3 then 0 else col1 end,col2 from (select *,(select max(col2)*0.75 from @t) col3 from @t b) aa order by 1 desc/*col1 col2----------- -----------6 165 200 10*/
