SAS Proc SQL計數問題

Question

我有一列數據，列名爲（Daily_Mileage）。我有15種不同類型的每日裏程和250行。我希望爲每日15個里程分別計數。我在SAS中使用PROC SQL，它不喜歡Cross join命令。我真的不知道我應該做的，但是這是我開始：

 
PROC SQL; 
select A, B 
From (select count(Daily_Mileage) as A from Work.full where Daily_Mileage = 'Farm Utility Vehicle (Class 7)') a 
cross join (select count(Daily_Mileage) as B from Work.full where Daily_Mileage = 'Farm Truck Light (Class 35)') b); 
QUIT; 

Answer 1

您可以先創建者的另一列，再總結該列和GROUP BY Daily_Mileage。如果我誤解了你的問題，請告訴我。

PROC SQL; 
    CREATE TABLE tab1 AS 
    SELECT Daily_Mileage, 1 AS Count, SUM(Count) AS Sum 
    FROM <Whatever table your data is in> 
     GROUP BY Daily_Mileage; 
QUIT; 

Answer 2

用例語句定義您的計數如下。

proc sql; 
    create table submit as 
    select sum(case when Daily_Mileage = 'Farm Utility Vehicle (Class 7)' 
        then 1 else 0 end) as A, 
     sum(case when Daily_Mileage = 'Farm Truck Light (Class 35)' 
        then 1 else 0 end) as B 
    from Work.full 
    ; 
quit ;

難道你不能只用一個proc頻率？

data example ; 
    input @1 Daily_Mileages $5. ; 
datalines ; 
TYPE1 
TYPE1 
TYPE2 
TYPE3 
TYPE3 
TYPE3 
TYPE3 
; 
run ; 

proc freq data = example ; 
    table Daily_Mileages ; 
run ; 

/* Create an output dataset */  
proc freq data = example ; 
    table Daily_Mileages /out=f_example ; 
run ;
