MySql Query Sent by Email - mysql

Question

I have a simple query that select some fields from a few different tables and I need it to run once a month. I know i can schedule a monthly "job" with the CREATE EVENT, however, is it possible to have that information emailed to some addresses after the query runs? That way i don't need to log into the server and look at the new file?

Answer 1

I think that Mysql doesn't support Email sending.
In this case, you can develop an auxiliary program that sends the file created, and execute it with - scheduled task, Cron ...(It depends on the Operating System of the server you're using).
The auxiliary program can be like this code adding the file/s you want to attach (attachFiles variable).
public class EmailAttachmentSender {
public static void sendEmailWithAttachments(String host, String port,
final String userName, final String password, String toAddress,
String subject, String message, String[] attachFiles)
throws AddressException, MessagingException {
// sets SMTP server properties
Properties properties = new Properties();
properties.put("mail.smtp.host", host);
properties.put("mail.smtp.port", port);
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.user", userName);
properties.put("mail.password", password);
// creates a new session with an authenticator
Authenticator auth = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
};
Session session = Session.getInstance(properties, auth);
// creates a new e-mail message
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(userName));
InternetAddress[] toAddresses = { new InternetAddress(toAddress) };
msg.setRecipients(Message.RecipientType.TO, toAddresses);
msg.setSubject(subject);
msg.setSentDate(new Date());
// creates message part
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(message, "text/html");
// creates multi-part
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// adds attachments
if (attachFiles != null && attachFiles.length > 0) {
for (String filePath : attachFiles) {
MimeBodyPart attachPart = new MimeBodyPart();
try {
attachPart.attachFile(filePath);
} catch (IOException ex) {
ex.printStackTrace();
}
multipart.addBodyPart(attachPart);
}
}
// sets the multi-part as e-mail's content
msg.setContent(multipart);
// sends the e-mail
Transport.send(msg);
}
/**
* Test sending e-mail with attachments
*/
public static void main(String[] args) {
// SMTP info
String host = "smtp.gmail.com";
String port = "587";
String mailFrom = "your-email-address";
String password = "your-email-password";
// message info
String mailTo = "your-friend-email";
String subject = "New email with attachments";
String message = "I have some attachments for you.";
// attachments
String[] attachFiles = new String[3];
attachFiles[0] = "e:/Test/Picture.png";
attachFiles[1] = "e:/Test/Music.mp3";
attachFiles[2] = "e:/Test/Video.mp4";
try {
sendEmailWithAttachments(host, port, mailFrom, password, mailTo,
subject, message, attachFiles);
System.out.println("Email sent.");
} catch (Exception ex) {
System.out.println("Could not send email.");
ex.printStackTrace();
}
}

Mysql does not support that functionality.
You can use a cron job (Quartz) to schedule a job every month,
where you can fetch the data and shoot an email containing your data.
Refer the below link for quartz job :

Answer 3

is it possible to have that information emailed to some addresses
after the query runs?
If you are looking for a MySQL built in solution then probably NO. This particular should be handled in application end.
So, if you are scheduling the query as cron job in linux (OR) batch job in windows then you can configure cron (or) batch to send an email to list of recipients once the query finishes.
How to configure cron to send mail can be checked HERE

I haven't done this myself but I see no reason why it shouldn't work: create a UDF (user defined function) that takes the e-mail parameters and sends out the e-mail. You can write UDFs e.g. in C++ and have so all necesssary libraries at hand.
