1064 – You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ” at line 5

Answer 1

you forgot to set the delimiter and misspelled a word:

delimiter |
CREATE TRIGGER TRIG BEFORE INSERT ON employee 
FOR EACH ROW BEGIN 
    UPDATE employee SET userId = userId +1 WHERE userId >1; 
END;
|
delimiter ;

If you don’t set another delimiter than ; the statement will end at the first ; and your trigger definition will be incomplete. You need to tell MySQL that the stamentment should end at the delimiter you defined. After that you can set the delimiter back with delimiter ;
