Mysql程序錯誤，

Question

我正在嘗試創建下面的mysql程序，但是我被困在最後兩個小時了，我不知道它有什麼問題。

delimiter $$ 
drop procedure if exists pos_finder; 
    create procedure pos_finder() 
    begin 
    declare below, normal, normal_h, svalue, eid, above int default 0; 
    declare bcounter, ncounter, acounter int default 0; 
    declare done int default 0; 
    declare userData cursor for select e.id, s.value, t.below_normal_h, 
t.Normal_b, t.Normal_h, t.above_normal_l from k_employee as e, k_trackers_data as s, k_trackers_sub as t where e.id = 3 and s.user_id = e.id and t.id = s.sub_tracker_id; 
    declare continue handler for not found set done = 1; 
    open userData; 
    fetch userData into eid, svalue, below, normal, normal_h, above; 
    if svalue < below then 
    set bcounter = bcounter + 1; 
    else if svalue > normal then 
    set ncounter = ncounter + 1; 
    else if svalue > above then 
    set acounter = acounter + 1; 
    end if; 
    close userData; 
    end$$ 

Mysql的說

ERROR 1064 (42000): 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 19 

這是接近用戶數據線。我在這裏和那裏移動換行符總是給這條線上的錯誤

請有人可以告訴我，我在做什麼錯了？

elseif而不是else[space]if。有了空間，您就可以開啓一個全新的if區塊。所以當你到達close電話時，有兩個「懸掛」的。
