Question

我一直在从事课堂作业，由于某种原因，我无法解决的唯一问题是带有课程的程序...有人可以为我提供指导吗？因此，我需要获取电子邮件的域并进行更新。示例：将boogers@us.now转换为boogers@gmail.com

规则需要一个游标：：

class AperioSlidesAfterDate(object):
  def go(self, session):
    return session.query(Slide).join(Image) ...
    # ^^^

如果未找到实际查询，请尝试使用该通用块：

Declare
V_Old Varchar2(30);
V_New Varchar2(30);
name_wo_domain Varchar2(30);
cursor DomainCursor is select Email_Address from Broker;
v_domain Varchar2(30) :='gmail.com';

BEGIN 
FOR i in DomainCursor
LOOP
      select REGEXP_SUBSTR(i.Email_Address,'[^@]+',1,1) 
      into name_wo_domain
      from dual;
      DBMS_OUTPUT.PUT_LINE(i.Email_Address || ' , ' );
      UPDATE Broker
      SET Email_Address = name_wo_domain||'@'||v_domain
      WHERE Email_Address = i.Email_Address;
    END LOOP;
COMMIT;
END ;
