无法使用此SQL摘要函数

在SAS SQL中生成摘要值的这一练习整天都让我疲惫不堪。它的SAS部分基本上只是我模拟一些数据，如果您想尝试回答问题，一般SQL原则适用

考虑以下因素：

输入数据

data test;
account_rk = 111111;
customer_rk = 111111;
ca_flag = 0;
score1 = 100;
score_with_ca = 0;
score_without_ca = 100;
output;
account_rk = 111111;
customer_rk = 222222;
ca_flag = 1;
score1 = 150;
score_with_ca = 150;
score_without_ca = 0;
output;
run;

已尝试摘要功能

proc sql;
create table test2 as 
select
account_rk,
sum(ca_flag) as sum_ca_flag,
    min(case
    when score_with_ca ne 0 then score_with_ca
    else score1 end) as min_score_with_ca,
    min(case 
    when score_without_ca eq 0 then score_without_ca
    else score1 end) as min_score_without_ca
from test
group by account_rk
having sum_ca_flag > 0;
quit;

期望的结果应该是什么样的

data test3;
account_rk = 111111;
sum_ca_flag = 1;
min_score_with_ca = 150;
min_score_without_ca = 100;
output;
run;

为了得到与第三步中生成的输出类似的输出，我需要在SQL中更改什么？这里的逻辑步骤是根据

ca\u flag

的值为

score1

生成最小值，并按

account\u rk

对其进行分组

谁能告诉我我做错了什么

谢谢

我想您只需要

NULL

或no

else

子句，然后是正确的逻辑：

proc sql;
create table test2 as 
    select account_rk, sum(ca_flag) as sum_ca_flag,
           min(case when score_with_ca > 0 then score_with_ca
               end) as min_score_with_ca,
           min(case when score_without_ca > 0 then score_without_ca
               end) as min_score_without_ca
    from test
    group by account_rk
    having sum_ca_flag > 0;
quit;

当你有Ca标志时，用Ca检查分数或不用Ca检查分数似乎很奇怪；但我认为这不是问题所在。谢谢你的回复。我想我这一天过得很糟糕…这是一个很容易解决的问题。。。
