在SQL语句中添加分数相同的项的相同排名

--建立测试环境

create table studentQK (CG float, MC int)

--插入数据

insert into studentQK

select 55, ' ' union all

select 65, ' ' union all

select 88, ' ' union all

select 88, ' ' union all

select 88, ' ' union all

select 66, ' ' union all

select 66, ' ' union all

select 90, ' ' union all

select 99, ' '

--测试

Update A Set MC=(Select IsNull(Count(Distinct CG),0)+1 from studentQK Where CG> A.CG) from studentQK A

Select * from studentQK Order By MC

--删除测试环境

Drop table studentQK

--结果

/*
