proc sql 中嵌套 select 语句的问题

Question

有人将此代码提供给运行，但即使在确定 left/right 括号的数量正确后，我仍不断收到错误消息。这是原始代码，因为我添加的括号似乎在错误的位置。

   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.

编辑：添加逗号后出现此错误：

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, ^, ^=, |, ||, ~, ~=.

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

错误不是括号错误，而是逗号(,)错误。您错过了第 5 行开头的逗号。

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

编辑： 用我的逗号修复缩进了原始代码。我不知道你为什么会收到这个新错误。我用逗号添加复制了你的原始代码，并用虚拟数据测试了你的代码，它工作正常。我猜是一些隐藏的垃圾字符导致了错误。

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
;;;;
run;
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;
