PL/SQL：在存储过程中出现错误 ORA-006550 PLS-00306

Question

我开发了一个存储过程，可以发送一次通知电子邮件，这样我就不会从我的显式光标“crs”中收到 100,000 封单独的电子邮件。 存储过程名称是“a_test_email”。我创建了一个名为“crs”的显式游标。游标查询 user_objects 以检查数据库中是否有任何对象无效。我对“a_test_email”存储过程如何循环发送电子邮件有疑问。 “批量收集”获取光标“crs”中的所有记录，然后发送一封电子邮件，将所有行（即记录）一起显示在一封电子邮件中。但是，我不断收到错误 ORA-0065550 PLS-00306。我不确定我做错了什么。请帮我用“a_test_email”存储过程纠正这个问题。

create or replace procedure a_test_email is

TYPE user_obj_tbl IS TABLE OF user_objects%ROWTYPE;
messages    user_obj_tbl;
v_email_body  varchar2(32767) := 'Oracle found ';

cursor crs is
 select *
 from user_objects
 where status = 'INVALID';

Begin

open crs;

loop
  fetch crs bulk collect into messages limit 100;
   exit when messages.count = 0;

  for indx in 1 .. messages.COUNT
  loop
    v_email_body := v_email_body||', '||messages(indx);
  end loop;
end loop;

v_email_body := v_email_body ||' object in your database. Please
troubleshoot issue. Thank you.';

email_format_test(p_to => 'test_email_1@testing.com',
                  p_cc => 'test_email_2@testing.com',
                  p_from => 'test_email_3@testing.com',
                  p_subject => 'INVALID OBJECTS '||messages.COUNT,
                  p_message => v_email_body,
                  p_smpt_host => '11.11.111.11'
                 );
 close crs;

 end;

utl_smtp.write_data(v_mail_conn, p_message ||utl_tcp.crlf||utl_tcp.crlf); 
utl_smtp.close_data(v_mail_conn); 

utl_smtp.quit(v_mail_conn); 
END; 

Answer 1

我认为问题就在这里。

v_email_body := v_email_body||', '||messages(indx);

Oracle 找不到将字符串与行类型连接的函数。消息（索引）是 user_object%rowtype。

试试这个。 v_email_body := v_email_body||', '||messages(indx).OBJECT_NAME;

Answer 2

您的过程语法无效。声明变量时不要使用=>。

改成这样：

create or replace procedure email_format_test(p_to IN varchar2, 
                                              p_cc IN varchar2, 
                                              p_from IN varchar2, 
                                              p_subject IN varchar2, 
                                              p_message IN varchar2, 
                                              p_smpt_host IN varchar2, 
                                              p_smpt_port IN number
                                              default 25) 

Answer 3

您正在使用 6 个参数调用该过程，但它需要 7 个参数（缺少 p_smpt_port 参数）。
