oracle 中有没有办法将数据从表导出到电子邮件?问题是，我有一个日志表，用于保存失败的日志.我想要一个程序来检查前一天是否有任何日志，如果有，则通过电子邮件发送它们.结果应该类似于:
is there a way in oracle how to export data from table to email? The thing is, I have a log table, where I keep failed logs. I would like to have a procedure which check if there are any logs on the day before, if yes then sends them in an email message. The result should look something like:
Log_id - Procedure_name - Fail_type - Message
Log_id - Procedure_name - Fail_type - Message
Log_id - Procedure_name - Fail_type - Message
Log_id - Procedure_name - Fail_type - Message
这就是我现在的程序
PROCEDURE send_mail(v_recipient VARCHAR2
,v_subject VARCHAR2
,v_text VARCHAR2
,v_from VARCHAR2 DEFAULT 'hsdfafjh@jhh.jij') IS
v_mail_host VARCHAR2(30) := 'hgiugiuyg';
v_mail_conn utl_smtp.connection;
crlf VARCHAR2(2) := chr(13) || chr(10);
BEGIN
v_mail_conn := utl_smtp.open_connection(v_mail_host, 25);
utl_smtp.helo(v_mail_conn, v_mail_host);
utl_smtp.mail(v_mail_conn, v_from);
utl_smtp.rcpt(v_mail_conn, v_recipient);
utl_smtp.data(v_mail_conn, 'Date: ' ||
to_char(SYSDATE, 'Dy, DD Mon YYYY hh24:mi:ss') || crlf ||
'From: ' || v_from || crlf || 'Subject: ' ||
v_subject || crlf || 'To: ' || v_recipient || crlf || crlf ||
v_text || crlf);
utl_smtp.quit(v_mail_conn);
EXCEPTION
WHEN utl_smtp.transient_error OR utl_smtp.permanent_error THEN
raise_application_error(-20000, 'Unable to send mail', TRUE);
END;
您可以生成 HTML 脚本并将其添加到邮件中.就像如果您想要表格格式一样，您可以创建 HTML 脚本并将其附加到邮件中.
You can generate an HTML script and add it in mail. Like if you want a tabular format, you can create the HTML script and attach it in mail.
以下内容供参考

你可以用你的表格替换你想要的数据.
You can substitute the data you want with your table.
