Question

I have a mysql table as follows.

CREATE TABLE `events` (
  `event_id` int(11) NOT NULL AUTO_INCREMENT,
  `eventName` varchar(45) DEFAULT NULL,
  `eventType` varchar(45) DEFAULT NULL,
  `user_id` varchar(45) DEFAULT NULL,
  `eventStartDate` date DEFAULT NULL,
  `eventStartTime` time DEFAULT NULL,
  `eventEndDate` date DEFAULT NULL,
  `eventEndTime` time DEFAULT NULL,
  `eventoptions` varchar(1000) DEFAULT NULL,
  PRIMARY KEY (`event_id`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=latin1;

I need to send an email three days before eventStartTime. I need query to get the event, I hope to through event get the user and send email. Can I do that using DATE_SUB(),
But how can I do that? I am very bad at sql.

I use Mysql connector Java.

Thank you!

Answer 1

   SELECT * from events where date_add(curdate(),INTERVAL 3 days)=eventStartTime 

This will give you all events which are 3 days from now.
