Answer 1

You should maintain a space between 'delimiter' key word and its values '//' , and ';'
Unless which it is a 1064 syntax error .

Example :

delimiter // -- <--- observe the space here. It is a MUST

-- your trigger definition

end;

//

delimiter ; -- <--- maintain space here too. This too is a MUST
