oracle sql cursor 使用邮件域名更新邮件域名

Question

我想给一个域名换一个新的域名。该过程将传递两个字符串。 不使用主键但使用电子邮件 执行程序('gmail.com', 'hotmail.com');

数据库中所有带有“Gmail.com”的电子邮件都将更改为“Hotmail.com”的新域名。 这是我的代码。

我在调用 PR_Q3 时遇到错误的参数数量或类型错误

create procedure PR_Q3
is P_NewEamil varchar2(50); P_OldEmail varchar2(50);
cursor E_info is select Email_Address from Broker where P_OldEmail = Email_Address
for update of Email_Address;
begin 
open E_info;
fetch E_info into P_NewEamil;
while E_info%found loop 
if(P_NewEamil like '%.com') then 
update Broker set Email_Address = P_NewEamil where Email_Address= P_OldEmail;
else 

 end if;
end loop;
close E_info;

 end PR_Q3;

Answer 1

您的程序应如下所示：

create procedure PR_Q3(p_oldemail in varchar2,
                       p_newemail in varchar2)
As
Begin

UPDATE BROKER
SET
    EMAIL_ADDRESS = REPLACE(EMAIL_ADDRESS, p_oldemail, p_newemail)
WHERE
    REGEXP_LIKE ( EMAIL_ADDRESS,'.*@'|| p_oldemail|| '$' );

Commit;

End;
/

要调用此过程，您需要传递两个域，如下所示：

Begin
Pr_q3('gmail.com', 'hotmail.com');
End;
/

干杯！！
