Sql 在帮助我获得2013年和2014年的计数时，作为一名新程序员，你能告诉我在代码中找到重复项的位置吗？@RamatuVictoryousKuyateh在这种情况下，第一个cte是从1-n开始为每个年/bill_成员id，如果您从cte中选择*，您将看到重复项

在帮助我获得2013年和2014年的计数时，作为一名新程序员，你能告诉我在代码中找到重复项的位置吗？@RamatuVictoryousKuyateh在这种情况下，第一个cte是从1-n开始为每个

年

/

bill_成员id

，如果您

从cte

中选择*，您将看到重复项的

RN

值，我们使用该值过滤掉重复项

，其中RN=1

。随后的

cte

每

一年获取一条记录

/

法案成员id

，并获取法案成员id有多少年记录的计数。
