What is wrong with my syntax when creating an event? phpmyadmin - mysql

Question

I have been at this for hours now, and I have tried everything I could find on stackoverflow and the internet. Nothing has worked. I have tried entering the code directly in the SQL prompt on phpmyadmin, as well as tried to create the event in the events tab.
For some odd reason, when giving it a second command, I get a syntax error. Each command on its own is accepted just fine. Together though? Syntax error.
Here's the code.
CREATE EVENT update_stats
ON SCHEDULE EVERY 15 MINUTE
ON COMPLETION PRESERVE ENABLE
DO
BEGIN
UPDATE stats JOIN temp_stats ON stats.unique_key = temp_stats.unique_key
SET stats.clicks = stats.clicks + temp_stats.clicks;
TRUNCATE temp_stats;
END
This yields a syntax error. I found a similar question on stackoverflow (see below) but none of the solutions worked. Yes, I tried setting and using a different delimiter. I even updated phpmyadmin to 4.4.1. Nothing works, just says I have a syntax error. I'm at my wits end here. MySQL 5.6.17.

Answer 1

I think this answer is missing an explanation as Jean-Francois was the correct answer but I didn't get it to work until I worked out what the "Delimiter" is.
When sending commands to SQL they are separated with a "Delimiter" the default is ";"
When I was making my event, inside the "CREATE EVENT" statement contains SQL queries inside the "BEGIN" and "END". SO MYSQL, parsing the query, runs into a ';' inside the BEGIN statement and correctly ends the statement there, saying "error in syntax near '' at line X" (the line it found the semi-colon on).
So to get around this you have to change the default delimiter for parsing, then run the query so you can include SQL statements inside your CREATE EVENT query with it ignoring the semi-colon and set the default delimiter back to a semi-colon:
DELIMITER $$
CREATE EVENT `snap_extcrs`
ON SCHEDULE
EVERY 1 DAY STARTS '2020-04-17 23:59:59'
ON COMPLETION PRESERVE
ENABLE
COMMENT ''
DO
BEGIN
INSERT INTO table (field, field2)
SELECT 1, 2 FROM table2
WHERE
date = DATE(NOW());
INSERT INTO table3 (field, field2)
SELECT 1, 2 FROM table2
WHERE
date = DATE(NOW());
END$$
DELIMITER ;

Answer 2

You forgot to put the END delimiter
DELIMITER #
CREATE EVENT update_stats
ON SCHEDULE
EVERY 15 MINUTE
ON COMPLETION PRESERVE ENABLE
DO BEGIN
UPDATE stats JOIN temp_stats ON stats.unique_key = temp_stats.unique_key
SET stats.clicks = stats.clicks + temp_stats.clicks;
TRUNCATE temp_stats;
END#
DELIMITER ;
