Hi All,

I have a requirement whenever a request is raised which comes as a new row in the database, i need to send a SMS and an email to the users. I wrote a trigger on my input table to send the SMS which is just a insert query into the SMS table. Now i also have to send an email. Please help me out how can i send an email from trigger. Is there is any way of invoking a Java Program from a Trigger?

Thanks in advance.

Yes, if your database supports Java. Does it?

If it doesn't some database include mechanisms to make calls to the OS shell. Also some database support the sending for notifications without the need to write a Java program to do it. Which database are you using?

If your database supports none of these things you could poll the table from your Java program. OK there will be a delay, but email is asynchronous so a delay is acceptable.

Oracle 10 does support Java so you could go down the Java route. Alternatively you could use the procedures in the UTL_SMTP package to do much the same.

Well, Oracle 9i also supports Java. And it contains the UTL_SMTP package.

Another solution would be to insert the message that you want to send with the all the necessary details and make a java scheduler that checks the content of this table from time to time and handles every record with the way it should.

This solution is more universal since not all databases support java.

The SMTP service appears not to be available.
