MySQL/phpMyAdmin freezes from DELIMITER

Question

Running this procedure causes MySQL (or phpMyAdmin) to freeze. I have to stop MySQL with from XAMPP command, which freezes and \"is not responding\" about 20 seconds before

Answer 1

the update command should:

update teams set live = live-1 where id = new.victim;
update teams where id = new.shooter set score = score+points;

the where after the set clause

Answer 2

As it turns out, phpMyAdmin has a field marked "delimiter:" below the SQL query box. Using it rather than the command solves the problem. Further research explains that "DELIMITER" is not a SQL command, but a command generally implemented by all SQL ui's.
