PL/SQL下邮件发送程序 - 数据库编程

对DBA而言，尽管在os级别下发送邮件是轻而易举的事情，然而很多时候我们也需要在PL/SQL中来发送邮件，比如监控job的执行状况等。本文根据网友(源作者未考证)的代码将其改装并封装到了package，感谢这位网友的无私奉献。文章首先给出演示调用该包发送邮件的情形后面给出了完整的代码。经测试Oracle 10g，Oracle 11g下均可用。关于os下发送邮件可参考：不可或缺的 sendEmail

1、调用SENDMAIL_PKG来发送邮件

gx_admin@SYBO2SZ> set serveroutput on;
gx_admin@SYBO2SZ> DECLARE 
  2    P_RECEIVER VARCHAR2(32767);
  3    P_SUB VARCHAR2(32767);
  4    P_TXT VARCHAR2(32767);
  5    ERR_NUM NUMBER;
  6    ERR_MSG VARCHAR2(32767);
  7  
  8  BEGIN 
  9    P_RECEIVER := 'robinson.chen@12306.com';
 10    P_SUB := 'Test mail';
 11    P_TXT := 'This is a test mail.';
 12    ERR_NUM := NULL;
 13    ERR_MSG := NULL;
 14  
 15    SENDMAIL_PKG.SENDMAIL ( P_RECEIVER, P_SUB, P_TXT, ERR_NUM, ERR_MSG );
 16  
 17    DBMS_OUTPUT.Put_Line('ERR_NUM = ' || TO_CHAR(ERR_NUM));
 18    DBMS_OUTPUT.Put_Line('ERR_MSG = ' || ERR_MSG);
 19  
 20    DBMS_OUTPUT.Put_Line('');
 21  
 22    COMMIT; 
 23  END;
 24  /
ERR_NUM = 0
ERR_MSG =

PL/SQL procedure successfully completed.
