CREATE TABLE tb(Name varchar(10),Score decimal(10,2))
INSERT tb SELECT 'aa',99
UNION ALL SELECT 'bb',56
UNION ALL SELECT 'cc',56
UNION ALL SELECT 'dd',77
UNION ALL SELECT 'ee',78
UNION ALL SELECT 'ff',76
UNION ALL SELECT 'gg',78
UNION ALL SELECT 'ff',50
GO
--1. 名次生成方式1,Score重复时合并名次
SELECT *,Place=(SELECT COUNT(DISTINCT Score) FROM tb WHERE Score>=a.Score)
FROM tb a
ORDER BY Place
/*--结果
Name Score Place
---------------- ----------------- -----------
aa 99.00 1
ee 78.00 2
gg 78.00 2
dd 77.00 3
ff 76.00 4
bb 56.00 5
cc 56.00 5
ff 50.00 6
就是理解不了Place=(SELECT COUNT(DISTINCT Score) FROM tb WHERE Score>=a.Score) 这句语句 有谁能帮帮我吗
