Question

我尝试执行此操作，但它在默认表空间中出错。我想给我创建的用户提供一个默认的表空间，但是如何？

BEGIN
  FOR USERNAME IN (SELECT studentname from students)
  LOOP
    EXECUTE IMMEDIATE 'CREATE USER ' || USERNAME.studentname  || ' IDENTIFIED BY ' || USERNAME.studentname;
    EXECUTE IMMEDIATE 'DEFAULT TABLESPACE "USERS"'; 
    EXECUTE IMMEDIATE 'TEMPORARY TABLESPACE "TEMP"';
    EXECUTE IMMEDIATE 'GRANT STUDENT TO ' || USERNAME.studentname ;                                    
  END LOOP;
END;

您需要将前三个语句合并为一个并添加适当的空格。由于您使用的是不区分大小写的标识符，因此不需要在表空间名称周围使用双引号。

BEGIN
  FOR USERNAME IN (SELECT studentname from students)
  LOOP
    EXECUTE IMMEDIATE 'CREATE USER ' || USERNAME.studentname  || ' IDENTIFIED BY ' || USERNAME.studentname ||
                      '  DEFAULT TABLESPACE USERS  
                        TEMPORARY TABLESPACE TEMP';
    EXECUTE IMMEDIATE 'GRANT UNLIMITED TABLESPACE TO ' || USERNAME.studentname;
    EXECUTE IMMEDIATE 'GRANT STUDENT TO ' || USERNAME.studentname ;                                    
  END LOOP;
END;

就个人而言，我总是使用SQL语句生成一个字符串，并将该字符串传递给EXECUTE IMMEDIATE。这样可以很容易地执行诸如记录执行的SQL语句或记录哪个语句失败等操作。这将使调试变得更加容易。
