與proc中的嵌套select語句問題sql

Question

我被授予此代碼運行，但我仍然收到錯誤，即使我已經確定有正確數量的左/右括號。這是原始代碼，因爲我添加的括號似乎在錯誤的地方。

proc sql; 
    create table all as 
    select distinct a.id, a.count, b.date 
    from (select distinct id, count (*) as count from (select distinct id, p_id, date2 from table1) group by id) a 
(select distinct id, min(date2) as date format datetime. from table1) b 
where a.id=b.id; 
quit; 



(select distinct id, min(date2) as date format datetime. from 
        --------    - 
        22     22 
        202     76 
3520! table1) group by id) b 
ERROR 22-322: Syntax error, expecting one of the following:), ','. 

ERROR 202-322: The option or parameter is not recognized and will be ignored. 

ERROR 76-322: Syntax error, statement will be ignored. 

編輯：添加一個逗號後，然後我得到這個錯誤：

256  , (select id, min(date2) as date format datetime. from 
256! table1) group by id) b 
            - 
            22 
            76 
ERROR 22-322: Syntax error, expecting one of the following: ;, !, !!, &, (, *, **, +, ',', -, 
       '.', /, <, <=, <>, =, >, >=, ?, AND, BETWEEN, CONTAINS, EQ, EQT, EXCEPT, GE, GET, 
       GT, GTT, HAVING, IN, INTERSECT, IS, LE, LET, LIKE, LT, LTT, NE, NET, NOT, NOTIN, 
       OR, ORDER, OUTER, UNION, ^, ^=, |, ||, ~, ~=. 

ERROR 76-322: Syntax error, statement will be ignored. 

257 Where a.id=b.id; 
258 quit;

的錯誤是沒有括號的，但逗號（，）。您在第五行開頭錯過了逗號。

, (select distinct id, min(date2) as date format datetime. from table1) b 

編輯：縮進原代碼與我的逗號修復。我不知道你爲什麼會得到這個新的錯誤。我複製了你的原始代碼，並添加了逗號，並用虛擬數據測試了你的代碼，並且它工作正常。我猜想一些隱藏的垃圾字符會導致錯誤。

data table1; 
input id p_id date2 :yymmdd10.; 
datalines; 
1 1 2012-01-15 
1 1 2012-01-15 
2 1 2012-01-15 
2 2 2012-01-15 
4 1 2012-01-15

     from (select distinct id, count (*) as count 
       from (select distinct id, p_id, date2 from table1) 
      group by id 
      ) a 
    , (select distinct id, min(date2) as date format datetime. 
     from table1 
    ) b 
where a.id=b.id; 
quit;
