I need help underdstanding a proc sql code in SAS as below: what kind of join are they doing here? 我需要了解SAS中的proc sql代码的帮助，如下所示：他们在这里进行哪种联接？

PROC SQL;
CREATE TABLE ACO AS  (
SELECT DISTINCT
ID,
c.OUTID
Reason
FROM s.cr             A
JOIN s.os            C        on a.AId = c.AId ;
quit();

Thank you in advance. 先感谢您。

A JOIN operator with no other qualifier is an INNER JOIN . 没有其他限定词的JOIN运算符是INNER JOIN 。
