如何從proc sql向本地SAS分配聚合值？

Question

我有麻煩調試如下因素proc sql：

%local datasetCount; 
%let datasetCount = 0; 

proc sql; 
      select count(*) 
      from path.dataset_list 
      into: &datasetCount.; * I also tried into: datasetCount; 
quit; 

什麼是我的語法錯誤？我得到以下

ERROR 22-322: Syntax error, expecting one of the following: ;, ',', ANSIMISS, CROSS, EXCEPT, FULL, 
       GROUP, HAVING, INNER, INTERSECT, JOIN, LEFT, NATURAL, NOMISS, ORDER, OUTER, RIGHT, 
       UNION, WHERE. 

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

您的訂單是錯誤的。如果& datasetcount是包含要存儲（可能不是）要存儲的變量的名稱的宏變量的名稱，則只需要「＆」符號。

proc sql; 
select count(1) into :datasetcount from path.dataset_list; 
quit;
